Alternative CNDOL Fockians for fast and accurate description of molecular exciton properties.

CNDOL is an a priori, approximate Fockian for molecular wave functions. In this study, we employ several modes of singly excited configuration interaction (CIS) to model molecular excitation properties by using four combinations of the one electron operator terms. Those options are compared to the experimental and theoretical data for a carefully selected set of molecules. The resulting excitons are represented by CIS wave functions that encompass all valence electrons in the system for each excited state energy. The Coulomb-exchange term associated to the calculated excitation energies is rationalized to evaluate theoretical exciton binding energies. This property is shown to be useful for discriminating the charge donation ability of molecular and supermolecular systems. Multielectronic 3D maps of exciton formal charges are showcased, demonstrating the applicability of these approximate wave functions for modeling properties of large molecules and clusters at nanoscales. This modeling proves useful in designing molecular photovoltaic devices. Our methodology holds potential applications in systematic evaluations of such systems and the development of fundamental artificial intelligence databases for predicting related properties.

Modification of the existing maximum residue levels in various plant commodities resulting from the use of potassium phosphonates.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicants De Sangosse SAS and Tilco-Alginure submitted two requests, respectively, to the competent national authorities in France and Germany to modify the existing maximum residue levels (MRLs) for the active substance potassium phosphonates in various plant commodities. The data submitted in support of the requests were found to be sufficient to derive MRL proposals for the commodities under assessment. For the derived MRL on baby leaf crops, further risk manager consideration is required to decide between two MRL options. Adequate analytical methods for enforcement are available to control the residues of potassium phosphonates in accordance with the residue definition 'phosphonic acid and its salts expressed as phosphonic acid' in the commodities under consideration. Based on the risk assessment results and assuming that the existing MRLs will be amended as proposed by EFSA in previous outputs, EFSA concluded that the long-term intake of residues resulting from the existing uses of fosetyl and phosphonates (previously assessed in a joint MRL review) and new proposed uses of potassium phosphonates is unlikely to present a risk to consumer health. Considering the toxicological profile of the active substance, a short-term dietary risk assessment was not required. The risk assessment shall be regarded as indicative because some MRL proposals derived by EFSA in the framework of the MRL review according to Articles 12 and 43 of Regulation (EC) No 396/2005 require further consideration by risk managers.

Review of the existing maximum residue levels for gamma-cyhalothrin according to Article 12 of Regulation (EC) No 396/2005.

According to Article 12 of Regulation (EC) No 396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance gamma-cyhalothrin. To assess the occurrence of gamma-cyhalothrin residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Commission Regulation (EU) No 188/2011, as well as the European authorisations reported by Member States (including the supporting residues data) in the framework of this review. Based on the assessment of the available data, MRL proposals were derived, and a consumer risk assessment was carried out. Although no risk to consumers was identified, some information required by the regulatory framework was missing. The residue definition for monitoring (lambda-cyhalothrin (includes gamma-cyhalothrin) (sum of R, S and S, R isomers)) covers both lambda- and gamma-cyhalothrin. Appropriate enantioselective techniques, which are not commonly used in routine analysis, are required to differentiate gamma-cyhalothrin residues from lambda-cyhalothrin. According to the available data, it is expected that the MRLs currently set in Regulation (EC) No 396/2005 will cover the uses of gamma-cyhalothrin assessed in the present review. Therefore, risk managers can consider maintaining the existing EU MRLs.

We present the complete mitochondrial genome of Carausius morosus from Salinas, CA. The mitochondrial genome of C. morosus is circular, AT rich (78.1%), and 16,671 bp in length. It consists of 13 protein-coding, 22 transfer RNA, and 2 ribosomal RNA genes and is identical in gene content to Carausius sp.

Evaluation of confirmatory data following the Article 12 MRL review for myclobutanil.

The applicant Corteva Agriscience submitted a request to the competent national authority in Austria to evaluate the confirmatory data that were identified for myclobutanil in the framework of the MRL review under Article 12 of Regulation (EC) No 396/2005 as not available. To address the data gap related to the lack of information on the triazole derivative metabolites (TDMs), new residue trials analysing for TDMs were submitted on apples, grapes, strawberries, tomatoes and melons. Following the assessment of the submitted data, EFSA concluded that Article 12 confirmatory data gaps are considered addressed for pome fruits, grapes, cucurbits with inedible peel, strawberries and tomatoes. The new information provided required the assessment of consumer exposure to TDMs, which identified no consumer intake concerns for the crops under consideration. No information was provided to address the Article 12 confirmatory data referred to in Regulation (EU) 2020/770 for blackberries, gooseberries, bananas, aubergines/eggplants, lamb's lettuces/corn salads, beans (with pods), globe artichokes, hops, sugar beet roots and products of animal origin. For these commodities, the existing EU MRL could be lowered to the enforcement limit of quantification (LOQ). For kaki/Japanese persimmon and azararoles/mediterranean medlars, the existing EU MRL is set on the basis of Codex MRL in pome fruits. The applicant did not request maintaining a Codex MRL in these commodities, but should risk managers decide otherwise, the Article 12 data gap is considered addressed for kaki/Japanese persimmon while for azaroles/Mediterranean medlars, a risk management decision might be required. No consumer intake concerns were identified.

The 2022 European Union report on pesticide residues in food.

Under European Union legislation (Article 32, Regulation (EC) No 396/2005), the European Food Safety Authority provides an annual report assessing the pesticide residue levels in foods on the European market. In 2022, 96.3% of the overall 110,829 samples analysed fell below the maximum residue level (MRL), 3.7% exceeded this level, of which 2.2% were non-compliant, i.e. results in a given sample exceeded the MRL after taking into account the measurement uncertainty. For the EU-coordinated multiannual control programme subset, 11,727 samples were analysed of which 0.9% were non-compliant. To assess acute and chronic risk to consumer health, dietary exposure to pesticide residues was estimated and compared with available health-based guidance values (HBGV). Continuation of the probabilistic assessment methodology was consolidated to all pesticides listed in the 2022 EU Regulation providing the probability of a consumer being exposed to an exceedance of the HBGV. Overall, the assessed risk to EU consumer's health is low. Recommendations to risk managers are given to increase the effectiveness of European control systems and to ensure a high level of consumer protection throughout the EU.

Modification of the existing maximum residue levels for fluxapyroxad in kaki/Japanese persimmons and cultivated mushrooms.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant BASF SE submitted two requests to the competent national authority in Spain and Ireland to modify the existing maximum residue levels (MRLs) for the active substance fluxapyroxad in kaki/Japanese persimmons and in cultivated fungi, respectively. The data submitted in support of the requests were found to be sufficient to derive MRL proposals for kaki/Japanese persimmons and cultivated fungi. Adequate analytical methods for enforcement are available to control the residues of fluxapyroxad on the commodities under consideration at the validated LOQ of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of fluxapyroxad, according to the reported agricultural practices, is unlikely to present a risk to consumer health. The long-term consumer risk assessment is indicative, pending the submission of the confirmatory data requested under the MRL review.

Herramientas para el tamizaje de aneurisma de aorta abdominal / Tools for abdominal aortic aneurysm screening

Introducción. El aneurisma de la aorta abdominal (AAA) es la dilatación de la aorta abdominal mayor de 1,5 veces el diámetro esperado. Su prevalencia es variable, con tasas reportadas de hasta el 12,5 %. Se considera como causa de muerte de más de 10.000 personas al año en los Estados Unidos. El objetivo de esta revisión de la literatura fue describir los factores de riesgo y las herramientas de tamizaje de AAA. Métodos. Se realizó una búsqueda de la literatura utilizando dos ecuaciones en bases de datos electrónicas, empleando términos seleccionados de "Medical Subject Heading" (MeSH) y "Descriptores en Ciencias de la Salud" (DeCS). Se evaluó la calidad de los estudios con la herramienta STROBE (Strengthening the Reporting of Observational Studies in Epidemiology). Resultados. Se recolectaron 40 artículos y a partir de ellos se construyó el texto de revisión, identificando en estos, los factores de riesgo asociados al desarrollo de AAA, tales como sexo masculino, tabaquismo, hipertensión arterial, antecedente familiar y obesidad, entre otros. La diabetes mellitus parece actuar como factor protector. Dentro de los instrumentos de tamizaje, el ultrasonido abdominal es uno de los más usados. Conclusión. El AAA es una patología multifactorial. En la actualidad la ultrasonografía de aorta es el método de elección para el tamizaje, permitiendo la detección precoz. El tamizaje de AAA con métodos no invasivos, como el ultrasonido, es útil sobre todo en zonas con prevalencia alta de la patología y en pacientes con determinados factores de riesgo.

Introduction. Abdominal aortic aneurysm (AAA) is a dilation of the abdominal aorta greater than 1.5 times the expected diameter. Its prevalence is variable, with reported rates of up to 12.5%. It is considered the cause of death of more than 10,000 people a year in the United States. The objective of this literature review was to describe risk factors and screening tools for AAA. Methods. A literature search was conducted using two equations in electronic databases, using terms selected from "Medical Subject Heading" (MeSH) and "Descriptors in Health Sciences" (DeCS). The quality of the studies was evaluated with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) tool. Results. Forty articles were collected and from them the review text was constructed, identifying the risk factors associated with the development of AAA, such as male sex, smoking, high blood pressure, family history and obesity, among others. Diabetes mellitus seems to act as a protective factor. Among the screening instruments, abdominal ultrasound is one of the most used. Conclusion. AAA is a multifactorial pathology. Currently, aortic ultrasonography is the method of choice for screening, allowing early detection. Screening for AAA with non-invasive methods, such as ultrasound, is useful especially in areas with a high prevalence of this pathology and in patients with certain risk factors.

Updated reasoned opinion on the toxicological properties and maximum residue levels (MRLs) for the benzimidazole substances carbendazim and thiophanate-methyl.

In compliance with Article 43 of Regulation (EC) No 396/2005, EFSA received from the European Commission in 2020 a mandate to provide its reasoned opinion on the toxicological properties and maximum residue levels (MRLs) for the benzimidazole substances carbendazim and thiophanate-methyl. Specifically, EFSA was asked to assess whether thiophanate-methyl or carbendazim has clastogenic potential and, in case clastogenic potential can be excluded, to derive toxicological reference values necessary for consumer risk assessment and assessment of maximum residue levels (MRLs). Although these active substances are no longer authorised within the European Union, MRLs were established by the Codex Alimentarius Commission (codex maximum residue limits; CXLs), and import tolerances are in place. Based on the assessment of the available data, toxicological reference values and MRL proposals were derived and a consumer risk assessment was carried out. Some information required by the regulatory framework was found to be missing and a possible acute risk to consumers was identified. Hence, the consumer risk assessment was considered indicative only and all MRL proposals derived by EFSA still require further consideration by risk managers. In October 2022, to ensure that MRLs derived by EFSA in its assessment of 2021 are safe for consumers also in view of endocrine-disrupting properties, EFSA was requested to carry out a follow-up assessment taking into account the scientific criteria for identifying endocrine disruptors (ED). Based on the outcome of the assessment, the experts agreed that the reference values are also covering the concern related to the identified hazards indicative of endocrine disruption for thiophanate-methyl. No further considerations on the impact of the ED assessment on the current reference values were needed for carbendazim since the ED criteria are not met for this substance. Therefore, the risk assessment and the MRL recommendations derived in 2021 are confirmed.

Evaluation of confirmatory data following the Article 12 MRL review for quizalofop-P-ethyl, quizalofop-P-tefuryl and propaquizafop and modification of the existing maximum residue levels for quizalofop-P-tefuryl.

The applicant Arysta Life Science Great Britain Limited submitted a request to the competent national authority in Croatia to evaluate the confirmatory data that were identified for quizalofop-P-tefuryl in the framework of the maximum residue level (MRL) review under Article 12 of Regulation (EC) No 396/2005 as not available. Since Article 12 data gaps were also set for the two other quizalofop-P variants sharing the same residue definitions for risk assessment and monitoring, EFSA included in the present assessment all quizalofop-P variants: quizalofop-P-ethyl, quizalofop-P-tefuryl and propaquizafop. Moreover, in the application submitted to Croatia, the applicant also included a request to modify the existing MRLs for quizalofop-P-tefuryl in grapes, sunflower seeds and soyabeans in accordance with Article 6 of Regulation (EC) No 396/2005. To address the data gaps, new data on hydrolysis efficiency of quizalofop-P-tefuryl, quizalofop acid, quizalofop-pentanoic acid and quizalofop-P-glycerate in different matrices of animal origin in accordance with the guidance document SANTE/2020/12830 Rev.1 were submitted, along with a validated analytical method for animal commodities. EFSA concluded that the data gap on validation of the efficiency of the extraction and hydrolysis included in the enforcement method of residues in livestock animal commodities was only fully addressed for muscle, poultry liver and eggs. Regarding plant commodities, the remaining data gaps were not addressed. EFSA also considered data gaps for quizalofop-p-ethyl in caraway as sufficiently addressed in the context of a previous MRL application. In general, the new information provided required a revision of the existing MRLs for several commodities of plant and animal origin. Further risk management considerations are required. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of quizalofop-P-tefuryl according to the reported agricultural practices is unlikely to present a risk to consumer health.

Evaluation of confirmatory data following the Article 12 MRL review and modification of the existing maximum residue levels for aluminium phosphide and magnesium phosphide.

The applicant Detia Freyberg GmbH submitted to the competent national authority in Germany two requests to evaluate the confirmatory data that were identified for tree nuts, oilseeds, cereals and commodities of animal origin in the framework of the maximum residue level (MRL) review under Article 12 of Regulation (EC) No 396/2005 as not available and two requests in accordance with Article 6 of Regulation (EC) No 396/2005 to increase the existing MRL for the active substance aluminium phosphide in peanuts, barley, oat, rye, rice and wheat, roots of herbal infusions, cocoa beans and seed spices and for the active substance magnesium phosphide in oilseeds (except peanuts) and pistachios. The four applications were combined by EFSA under the current assessment. To address the data gaps, validation data for the method of analysis for enforcement of phosphide in high-oil content commodities and new residue trials were submitted. The data gaps on additional residue trials supporting authorisations on oilseeds and cereal grains, on clarifications regarding the discrepancies observed in the residue trial results for pistachios, and on data confirming the negligible occurrence of phosphane and its oxidation products in livestock products were considered addressed. The data gap on independent laboratory validation (ILV) and a confirmatory method for monitoring of phosphide in high-oil content commodities was considered not fully addressed. The information provided justified a lowering of the current tentative MRLs for the whole group of cereals (except rice and 'others'), an increase of the current tentative MRLs for pistachios, the whole group of oilseeds, rice and 'other' cereals, herbal infusions from roots, cocoa beans and seed spices, and a revision of the risk assessment performed for phosphane and its phosphide salts. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of AlP and Mg3P2 according to the reported agricultural practices is unlikely to present a risk to consumer health. Further risk management considerations are required.

Modification of the existing maximum residue level for clopyralid in honey.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Corteva Agriscience International Sàrl submitted a request to the competent national authority in Finland to modify the existing maximum residue levels (MRLs) for the active substance clopyralid in honey. The data submitted in support of the request were found to be sufficient to derive MRL proposals for honey. Adequate analytical methods for enforcement are available to control the residues of clopyralid (including potential conjugates) in honey at the validated limit of quantification (LOQ) of 0.001 mg/kg. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of clopyralid residues in honey, resulting from the authorised use of clopyralid on oilseed rape notified in the present MRL assessment, is unlikely to present a risk to consumer health.

Modification of the existing maximum residue levels for flonicamid in various crops.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant ISK Biosciences Europe N.V. submitted two requests to the competent national authority in Finland and Belgium, respectively, to modify the existing maximum residue levels (MRLs) for the active substance flonicamid in potatoes and in various crops. The data submitted in support of the requests were found to be sufficient to derive MRL proposals for potatoes, lettuces and salad plants, spinaches and similar leaves, beans (without pods), cardoons, celeries, Florence fennels and rhubarbs. Adequate analytical methods for enforcement are available to control the residues according to the residue definition as of the sum of flonicamid, TFNA and TFNG, expressed as flonicamid in the plant matrices under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg for each compound. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the uses of flonicamid according to the reported agricultural practices is unlikely to present a risk to consumer health.

Modification of the temporary maximum residue levels for mepiquat in cultivated fungi and oyster mushrooms.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant BASF SE submitted a request to the competent national authority in Finland to modify the temporary maximum residue level (MRL) to a permanent MRL for the active substance mepiquat in cultivated fungi (with a specific MRL for oyster mushrooms). The data submitted in support of the request (monitoring data from food business operators) are not sufficient to derive permanent MRL proposals. The assessment of these data, complemented by an analysis of the most recent monitoring data available from EU monitoring programmes, supports the conclusion that the existing t-MRL for cultivated fungi is still sufficient to account for the residue uptake in cultivated mushrooms other than oyster mushrooms. It was also noted that lower t-MRLs could be derived based on the assessment of the most recent monitoring data. A risk management decision is still needed on whether to maintain the existing t-MRL value. Regarding oyster mushrooms, EFSA derived different options for risk managers to eventually update the values of the temporary MRLs based on the most recent monitoring data from food business operators. Adequate analytical methods for enforcement are available to control the residues of mepiquat (expressed as mepiquat chloride) in the commodities under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the cross-contamination of untreated cultivated fungi (including oyster mushrooms) from cereal straw lawfully treated with mepiquat according to the current agricultural practices is unlikely to present a risk to consumer health.

Targeted review of maximum residue levels (MRLs) for profenofos.

In accordance with Article 43 of Regulation (EC) 396/2005, EFSA received a request from the European Commission to review the existing maximum residue levels (MRLs) for the non-approved active substance profenofos in view of the possible lowering of the MRL. EFSA investigated the origin of the current EU MRLs. Existing EU MRLs are based on Codex Maximum Residue Limits still in place or reflect temporary MRLs set from monitoring data. EFSA performed an indicative chronic and acute dietary risk assessment for the list of MRLs to allow risk managers to take the appropriate decisions. For some commodities, further risk management discussions are required to decide which of the risk management options proposed by EFSA should be implemented in the EU MRL legislation.

Setting of an import tolerance for fenazaquin in hops.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Gowan Crop Protection Limited submitted a request to the competent national authority in Greece to set an import tolerance for the active substance fenazaquin in hops imported from the United States of America. The data submitted in support of the request were found to be sufficient to derive an maximum residue limit (MRL) proposal for hops. An adequate analytical method for enforcement is available to control the residues of fenazaquin in the plant matrix under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues of fenazaquin and its toxicologically relevant plant metabolite TBPE resulting from the use of fenazaquin on imported hops from United States according to the reported agricultural practice is unlikely to present a risk to consumer health.

Targeted review of maximum residue levels (MRLs) for chlorfenapyr.

In accordance with Article 43 of Regulation (EC) 396/2005, EFSA received a request from the European Commission to review the existing maximum residue levels (MRLs) for the non-approved active substance chlorfenapyr in view of the possible lowering of the MRL set for tea. This current EU MRL is based on an import tolerance established in 2007. EFSA reviewed the toxicological data assessed by other scientific bodies, proposing toxicological reference values to be used for an indicative risk assessment, noting that the values are affected by additional, non-standard uncertainties. According to the indicative chronic and acute dietary risk assessment the existing MRL for tea does not pose an unacceptable risk for consumers. Further risk management discussions are required to decide which of the risk management options proposed by EFSA should be implemented in the EU MRL legislation.

Modification of the existing maximum residue levels and setting import tolerances for flupyradifurone and difluoroacetic acid (DFA) in various crops.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Bayer AG, Crop Science Division submitted a request to the competent national authority in the Netherlands to modify the existing maximum residue levels (MRL) and to set import tolerances for flupyradifurone and its metabolite difluoroacetic acid (DFA) in various plant commodities. The data submitted in support of the request were found to be sufficient to derive MRL proposals for flupyradifurone and DFA in avocados, mangoes, papayas, asparagus, sesame seeds, sunflower seeds, sugar beet roots and chicory roots. Adequate analytical methods for enforcement are available to control the residues of flupyradifurone and DFA in plant matrices under consideration at the validated limits of quantification (LOQs) of 0.01 and 0.007 mg/kg, respectively. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of flupyradifurone and DFA residues resulting from the use of flupyradifurone according to the reported agricultural practices is unlikely to present a risk to consumer health.

Setting of an import tolerance for lambda-cyhalothrin in avocados.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Syngenta Crop Protection AG submitted a request to the competent national authority in Greece to set an import tolerance for the active substance lambda-cyhalothrin in avocados. The data submitted in support of the request were found to be sufficient to derive maximum residue level (MRL) proposals for avocados. Since the general data gap related to toxicity of degradation products formed under sterilisation conditions and identified in the framework of the MRL review has not yet been addressed, a risk management decision is required as to whether it is appropriate to take over the proposed MRLs in the MRL legislation. Adequate analytical methods for enforcement are available to control the residues of lambda-cyhalothrin in the commodity under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of lambda-cyhalothrin according to the reported agricultural practice is unlikely to present a risk to consumer health. However, the consumer exposure calculation shall be considered provisional, pending the toxicological assessment of the compounds formed under sterilisation conditions.

Review of the existing maximum residue levels for zoxamide according to Article 12 of Regulation (EC) No 396/2005 and setting of an import tolerance for onions, garlic and shallots.

According to Article 12 of Regulation (EC) No 396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance zoxamide. To assess the occurrence of zoxamide residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Regulation (EC) No 1107/2009, the MRLs established by the Codex Alimentarius Commission and the European authorisations reported by Member States and the UK (including the supporting residues data). Based on the assessment of the available data, MRL proposals were derived, and a consumer risk assessment was carried out. Although no apparent risk to consumers was identified, some information required by the regulatory framework was missing. Hence, the consumer risk assessment is considered indicative only and some MRL proposals derived by EFSA still require further consideration by risk managers. Furthermore, in accordance with Article 6 of Regulation (EC) No 396/2005, the Applicant Gowan Crop Protection Ltd, submitted a request to the competent national authority in Latvia to set an import tolerance for zoxamide in onions (extrapolated to garlic and shallots) based on the use authorised in USA. The data submitted in support of the request were found to be sufficient to derive MRL proposals for all crops under assessment. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of zoxamide according to the agricultural practices on onions, garlic and shallots is unlikely to present a risk to consumer health.
