Characterisation of "flushable" and "non-flushable" commercial wet wipes using microRaman, FTIR spectroscopy and fluorescence microscopy: to flush or not to flush.

The introduction to the market of wet wipes, advertised and labelled as "flushable", has been the subject of controversy due to their perceived potential to block sewer systems as observed with other non-woven cloths such as traditional non-flushable wipes. Non-woven cloths that enter wastewater systems can find their way into the aquatic environment via wastewater effluents and it has been suggested that the breakdown of these fabrics can release materials such as microplastics into the environment. Worldwide research has revealed the alarming number of aquatic organisms affected by the presence of plastic debris in the aquatic environment harbouring a potential risk to humans through the introduction of microplastics into the food chains. However, the actual material composition of flushable wipes, their fate and impacts in the aquatic environment have not yet been scientifically studied. This paper investigates the fibre composition of flushable and non-flushable wipes, specifically with regard to synthetic polymer material, using Fourier transform infrared (FTIR) and microRaman spectroscopy along with fluorescence microscopy. The study demonstrated the presence of polyester (polyethylene terephthalate, (PET)), high-density polyethylene (HDPE) and polyethylene/vinyl acetate (PEVA/EVA) in some flushable wipes and PET in all non-flushable. Other polymers such us polypropylene (PP), low-density polyethylene (LDPE), expanded polystyrene (EPS) and polyurethane (PU) were also identified as potential components in the flushable material. Hence, commercially available wet wipes labelled as flushable could also be considered as a possible source of microplastic fibres in the wastewater streams and, if not retained, in the environment.

Patterns of cleaning product exposures using a novel clustering approach for data with correlated variables.

PURPOSE: Clustering methods may be useful in epidemiology to better characterize exposures and account for their multidimensional aspects. In this context, application of clustering models allowing for highly dependent variables is of particular interest. We aimed to characterize patterns of domestic exposure to cleaning products using a novel clustering model allowing for highly dependent variables. METHODS: To identify domestic cleaning patterns in a large population of French women, we used a mixture model of dependency blocks. This novel approach specifically models within-class dependencies, and is an alternative to the latent class model, which assumes conditional independence. Analyses were conducted in 19,398 participants of the E3N study (women aged 61-88 years) who completed a questionnaire regarding household cleaning habits. RESULTS: Seven classes were identified, which differed with the frequency of cleaning tasks (e.g., dusting/sweeping/hoovering) and use of specific products (e.g., bleach, sprays). The model also grouped the variables into conditionally independent blocks, providing a summary of the main dependencies among the variables. CONCLUSIONS: The mixture model of dependency blocks, a useful alternative to the latent class model, may have broader application in epidemiology, in particular, in the context of exposome research and growing need for data-reduction methods.

Classification of consumer products under the EU CLP Regulation: what to consider when caring for contact dermatitis patients.

Possibly hazardous chemical substances and mixtures need to be clearly and correctly classified and labelled, in order for their hazards to be properly identified and communicated. As dermatologists may encounter cases of harm to patients induced by chemicals, such as chemical burns, and irritant and allergic contact dermatitis, it is essential for them to be aware of the EU CLP Regulation and its potential pitfalls. Manufacturers are required by CLP to classify their products according to the rules given in the CLP Regulation. The enforcement duty lies with the Member States and their competent authorities. Dangerous non-food consumer products have to be reported to the European Commission to be entered into the Rapid Alert System for Dangerous Non-food Products (RAPEX) notifications. The sheer complexity of the CLP Regulation and lack of awareness of its ramifications by companies, competent authorities, consumer associations and the public at large may prevent efficient enforcement actions. When dermatologists become aware of inappropriately labelled chemicals, they should inform the competent authorities.

Presence in, and release of, nanomaterials from consumer products.

Widespread use of engineered nanomaterials (ENMs) in consumer products has led to concerns about their potential impact on humans and the environment. In order to fully assess the impacts and release of ENMs from consumer products, this chapter provides an overview of the types of consumer products that contain nanomaterials, the potential release mechanisms of these ENMs from consumer products, and the associated human exposure. Information from two large datasets on consumer goods associated with ENMs, namely, the U.S.-based Project for Emerging Nanotechnologies from the Woodrow Wilson International Center, and the European-based National Institute for Public Health and the Environment of Netherlands, have been summarized. These databases reveal that silver, titanium, carbon-based ENMs are the major nanomaterials associated with consumer products. The presence and potential release of silver, titanium, carbon-based, and other nanomaterials from consumer goods available in published literature are also summarized, as well as the potential human exposure scenarios of inhalation, ingestion, dermal, and combination of all means. The prospecting of nanomaterial in water and biosolids provides further evidence of ENM occurrence, which could be linked to the use of nanomaterials containing consumer goods. Finally, this overview provides guidelines on toxicity studies, which calls for further efforts to analyze the biological effects of ENMs on human beings and their exposure pathways in consumer products.

[Poisoning with household cleaning products in a city in Northeast Brazil]. / Avaliação das intoxicações por domissanitários em uma cidade do Nordeste do Brasil.

This study analyzes toxic exposures to household cleaning products based on data from the Center for Notification and Treatment of Poisoning (CEATOX) in Campina Grande, Paraíba State, Brazil, from 2007 to 2010. The data were collected from the reporting forms from the Information System on Notifiable Diseases (SINAN), analyzed with SPSS (Version 17). Chemical identification was performed in urine samples using high-resolution chromatography techniques (GC-MS and HPLC-UV). Six hundred and sixty cases of poisoning were reported, with pesticides as the principal causal agents (42.2%). Poisoning with household cleaning products occurred mainly in children (30.1%) and/or females (55.21%) who were exposed to the product accidentally (55.4%) by the oral route (82%). These data indicate that poisoning with household cleaning products in Campina Grande should be treated with specific prevention and control measures, including evaluation of ease of access to pesticides, in order to reach the goals set by the Brazilian National Health Plan for 2012-2015.

The epidemiology of chemical eye exposures reported to the Victorian Poisons Information Centre.

OBJECTIVE: We aimed to determine the epidemiology of chemical eye exposures reported to the Victorian Poisons Information Centre, Australia. METHODS: This was a prospective case series comprising consecutive calls to the Victorian Poisons Information Centre that related to chemical eye exposures (January 2009-2010). Data included patient demographics, place and cause of exposure, nature of the chemical, symptoms and advice given. Patients were telephoned 48 h later to determine the outcome and whether the advice had been taken. RESULTS: One thousand four hundred and eighty patients were enroled (45.7%, aged <16 years) with 937 (63.3%) followed up. Cleaning agents (32.6%), topical personal products (25.4%), industrial agents (11.8%), herbicides/pesticides (5.7%), petroleum products (4.2%) and miscellaneous agents (20.3%) comprised the exposure groups. Men were exposed to significantly more industrial agents (74.8 vs. 25.2%) and fewer topical personal agents (31.3 vs. 68.7%) than women, (P<0.001). Children were exposed to significantly more topical personal agents (65.2 vs. 34.8%) and fewer industrial agents (28.7 vs. 71.3%) than adults (P<0.001). The median time between exposure and the call for advice was significantly shorter for children (P<0.001). Eight hundred and ten (54.7%) patients were advised that medical care was not required. The remainder were advised to seek care or were already receiving care. At follow-up, only 63 (6.7%) patients were symptomatic. Eight hundred and fifty patients (90.8%) had complied with the advice given. There were no compliance differences between men/women and children/adults (P>0.05). CONCLUSION: Most exposures are of little consequence. However, there are clear epidemiological differences between sex and age groups. These findings will help inform prevention strategies.

Targeting aquatic microcontaminants for monitoring: exposure categorization and application to the Swiss situation.

BACKGROUND, AIM, AND SCOPE: Aquatic microcontaminants (MCs) comprise diverse chemical classes, such as pesticides, biocides, pharmaceuticals, consumer products, and industrial chemicals. For water pollution control and the evaluation of water protection measures, it is crucial to screen for MCs. However, the selection and prioritization of which MCs to screen for is rather difficult and complex. Existing methods usually are strongly limited because of a lack of screening regulations or unavailability of required data. METHOD AND MODELS: Here, we present a simple exposure-based methodology that provides a systematic overview of a broad range of MCs according to their potential to occur in the water phase of surface waters. The method requires input of publicly available data only. Missing data are estimated with quantitative structure-property relationships. The presented substance categorization methodology is based on the chemicals' distribution behavior between different environmental media, degradation data, and input dynamics. RESULTS: Seven different exposure categories are distinguished based on different compound properties and input dynamics. Ranking the defined exposure categories based on a chemical's potential to occur in the water phase of surface waters, exposure categories I and II contain chemicals with a very high potential, categories III and IV contain chemicals with a high potential, and categories V and VI contain chemicals with a moderate to low potential. Chemicals in category VII are not evaluated because of a lack of data. We illustrate and evaluate the methodology on the example of MCs in Swiss surface waters. Furthermore, a categorized list containing potentially water-relevant chemicals is provided. DISCUSSION: Chemicals of categories I and III continuously enter surface waters and are thus likely to show relatively steady concentrations. Therefore, they are best suited for water monitoring programs requiring a relatively low sampling effort. Chemicals in categories II and IV have complex input dynamics. They are consequently more difficult to monitor. However, they should be considered if an overall picture is needed that includes contaminants from diffuse sources. CONCLUSIONS: The presented methodology supports compound selection for (a) water quality guidance, (b) monitoring programs, and (c) further research on the chemical's ecotoxicology. The results from the developed categorization procedure are supported by data on consumption and observed concentrations in Swiss surface waters. The presented methodology is a tool to preselect potential hazardous substances based on exposure-based criteria for policy guidance and monitoring programs and a first important step for a detailed risk assessment for potential microcontaminants.

Classification of abused inhalants.

Many hundreds of household and industrial products can be volatilized readily and are subject to abuse. Inhalant abuse research has been hampered by a lack of consensus on whether or not there are subclassifications of abused inhalants based on chemical structure, form or intended use of the product or pharmacological properties. This paper discusses strengths and weaknesses of various approaches to classification of inhalants and suggests areas for future research in this area. It is concluded that classification of inhalants by form or product types is not useful for scientific purposes; rather, subclassification of inhalants should be based on a yet-to-be-determined combination of chemical and pharmacological similarity and shared patterns of abuse. One of the ways in which we can improve our understanding of inhalant abuse is to obtain more detailed information on individual products and chemicals, their patterns of use and the geographical distribution of their use.

Composition and production rate of solid waste from dental laboratories in Xanthi, Greece.

The composition and production rate of solid waste produced by four dental laboratories were measured in the Prefecture of Xanthi (Greece) during 2002. The selected dental labs in Xanthi were expected to produce approximately 75% of the waste produced from of all seven dental laboratories in the Xanthi Prefecture. Sampling was performed during a 2-month period. Solid waste was categorized into three major categories: (a) infectious and potentially infectious waste, (b) non-infectious toxic waste and (c) household type solid waste. Dental laboratories solid waste (DLSW) was produced at a rate of 0.059 g/cap/day (or 22 g/cap/year) at the time of the study. Household type waste, infectious and potentially infectious waste and non-infectious toxic waste comprised approximately 74%, 26% and less than 0.5% of the total DLSW weight produced, respectively. DLSW was estimated to be approximately 0.007% of the amount of municipal solid waste produced in the Prefecture of Xanthi.

Household hazardous waste data for the UK by direct sampling.

The amount of household hazardous waste (HHW) disposed of in the United Kingdom (UK) requires assessment. This paper describes a direct analysis study carried out in three areas in southeast England involving over 500 households. Each participating householder was provided with a special bin in which to place items corresponding to a list of HHW. The amount of waste collected was split into nine broad categories: batteries, home maintenance (DIY), vehicle upkeep, pesticides, pet care, pharmaceuticals, photographic chemicals, household cleaners, and printer cartridges. Over 1 T of waste was collected from the sample households over a 32-week period, which would correspond to an estimated 51,000 T if extrapolated to the UK population for the same period or over 7,000 T per month. Details of likely disposal routes adopted by householders were also sought, demonstrating the different pathways selected for different waste categories. Co-disposal with residual household waste dominated for waste batteries and veterinary medicines, hence avoiding classification as hazardous waste under new UK waste regulations. The information can be used to set a baseline for the management of HHW and provides information for an environmental risk assessment of the disposal of such wastes to landfill.

Comparison of different collection systems for sorted household waste in Sweden.

Composition and quantity per person of municipal solid waste (MSW) have been analyzed in six municipalities in southern Sweden with similar socio-economic conditions but with different collection systems. Samples of residual waste have been sorted, classified and weighed in 21 categories during 26 analyses that took place from 1998-2004. Collection data of the total waste flow, including source sorted recycling materials, in the same area have been compiled and compared. Multivariate data analyses have been applied. Weight-based billing reduced delivered amounts of residual household waste by 50%, but it is unknown to what extent improper material paths had developed. With curbside collection more metal, plastic and paper packaging was separated and left to recycling. When separate collection of biodegradables was included in the curbside system, the overall sorting of dry recyclables increased. The large uncertainty associated with waste composition analyses makes it difficult to draw strong conclusions regarding the effects on specific recyclables or the changes in the composition of the residual waste.

Household hazardous waste: composition of paint waste.

'Paint waste', a part of the 'household hazardous waste', amounting to approximately 5 tonnes was collected from recycling stations in two Danish cities. Sorting and analyses of the waste showed paint waste comprised approximately 65% of the mass, paint-like waste (cleaners, fillers, etc.) comprised 15-25% and foreign items comprised 10-20%.Water-based paint was the dominant part of the paint waste. The chemical composition of the paint waste and the paint-like waste was characterized by an analysis of 27 substances in seven waste fractions. The content of critical substances was low and the paint waste was less contaminated with heavy metals than was the ordinary household waste. This may suggest that households no longer need to source-segregate their paint if the household waste is incinerated, since the presence of a small quantity of solvent-based paint will not be harmful when incinerated. Allowing household paint waste to be collected with ordinary household waste is expected to reduce the cost of handling household hazardous waste, since paint waste in Denmark comprises the major fraction of household hazardous waste.

Microbial inactivation by microwave radiation in the home environment.

The study reported here looked at the survival of microorganisms (heterotrophic plate counts, total coliforms, E. coli, and bacterial spores) in a consumer-type microwave oven. Kitchen sponges, scrubbing pads, and syringes were experimentally contaminated with wastewater and subsequently exposed to microwave radiation. At 100 percent power level, it was found that the heterotrophic plate count (i.e., total bacterial count) of the wastewater was reduced by more that 99 percent within 1 to 2 minutes, and the total coliform and E. coli were totally inactivated after 30 seconds of microwave radiation. Bacterial phage MS2 was totally inactivated within 1 to 2 minutes. Spores of Bacillus cereus were more resistant than the other microorganisms tested, and were completely eradicated only after 4-minute irradiation. Similar inactivation rates were obtained in wastewater-contaminated scrubbing pads. Microorganisms attached to plastic syringes were more resistant to microwave irradiation than those associated with kitchen sponges or scrubbing pads. It took 10 minutes for total inactivation of the heterotrophic plate count and 4 minutes for total inactivation of total coliform and E. coli. A 4-log reduction of phage MS2 was obtained after 2 minutes; 97.4 percent reduction was observed after 12 minutes. The authors also observed a higher inactivation of B. cereus spores in syringes placed in a ceramic container than of spores in syringes placed in a glass container. This finding could have some implications for the design of containers to be used in exposure of medical devices to microwave radiation. The article discusses the implications of these findings for consumer safety in the home environment.

Assessing poisoning risks related to storage of household hazardous materials: using a focus group to improve a survey questionnaire.

BACKGROUND: In fall of 2004, the authors began an investigation to characterize the correlations between the storage of Household Hazardous Materials and the associated health risks, particularly to children. The study area selected was Genesee County, Michigan, near Flint, with data to be collected by a phone survey of residents and through the acquisition of county hospital records containing procedure codes indicating treatment for poison emergencies, and review of poison control center data. METHODS: A focus group was used to identify key topics and relationships within these data for improving the phone survey questionnaire and its analysis. RESULTS: The focus group was successful in identifying the key issues with respect to all the data collection objectives, resulting in a significantly shorter and more topically focused survey questionnaire. Execution time of the phone survey decreased from 30 to 12 minutes, and useful relationships between the data were revealed, e.g., the linkage between reading food labels and reading labels on containers containing potentially harmful substances. CONCLUSION: Focus groups and their preparatory planning can help reveal data interrelationships before larger surveys are undertaken. Even where time and budget constraints prevent the ability to conduct a series of focus groups, one successful focus group session can improve survey performance and reduce costs.

Exposure misclassification of household pesticides and risk perception and behaviour.

The aim of this paper was to compare self-reported household pesticide use or non-use in a questionnaire with reported household pesticide use from an in-depth interview, in order to elucidate any differences, and to study any differential reporting of pesticides. In the in-depth interview we asked for pesticide use, behaviour adopted while using pesticides and risk perceptions as possible factors to explain the reporting of pesticide use. The Avon Longitudinal Study of Parents and Children (ALSPAC) was used as the sampling frame. Eight hundred and thirty one parents filled out and returned the questionnaire. A random sample of 53 users and 94 non-users took part in the interview. Almost 90% of the 94 who did not report the use of pesticides in the questionnaire reported the use of pesticides during the interview. However, those who reported pesticide use in the questionnaire were more likely to report home and garden pesticide use (P < 0.05) in the interview. The parents who reported pesticide use in the questionnaire had a tendency to perceive a lower risk and higher benefit from pesticide use, and tended to be less risk averse when compared with the groups of parents who reported no pesticide use. They bought the pesticides because 'they looked safe', while those who did not report pesticide use bought them because they 'used them before'. The latter were also more likely to state that they did not understand everything on the label and that they thought that it did not provide all the information needed. They were also less likely to feel that they knew what they are doing when using pesticides and felt that pesticide use is relatively dangerous compared with other hazards. In conclusion, pesticide use is underreported in questionnaires, and behaviour and risk perception may affect the reporting.

An epidemiological study of poisoning cases reported to the National Poisons Information Centre, All India Institute of Medical Sciences, New Delhi.

A retrospective analysis of poisoning calls received by the National Poisons Information Centre showed a total of 2719 calls over a period of three years (April 1999-March 2002). The queries were made on poisoning management (92%) and information (8%) about various products and functioning of the centre. The data were analysed with respect to age, sex, mode and type of poisoning. The agents belonged to various groups: household products, agricultural pesticides, industrial chemicals, drugs, plants, animal bites and stings, miscellaneous and unknown groups respectively. The age ranged from less than 1 to 70 years, with the highest incidence in the range of 14-40 years, with males (57%) outnumbering females (43%). The most common mode of poisoning was suicidal (53%), followed by accidental (47%). The route of exposure was mainly oral (88%). Dermal (5%), inhalation and ocular exposure contributed 7% to the total. The highest incidence of poisoning was due to household agents (44.1%) followed by drugs (18.8%), agricultural pesticides (12.8%), industrial chemicals (8.9%), animals bites and stings (4.7%), plants (1.7%), unknown (2.9%) and miscellaneous groups (5.6%). Household products mainly comprised of pyrethroids, rodenticides, carbamates, phenyl, detergents, corrosives etc. Drugs implicated included benzodiazepines, anticonvulsants, analgesics, antihistamines, tricyclic antidepressants, thyroid hormones and oral contraceptives. Among the agricultural pesticides, aluminium phosphide was the most commonly consumed followed by organochlorines, organophosphates, ethylene dibromide, herbicides and fungicides. Copper sulphate and nitrobenzene were common among industrial chemicals. The bites and stings group comprised of snake bites, scorpion, wasp and bee stings. Poisoning due to plants was low, but datura was the most commonly ingested. An alarming feature of the study was the high incidence of poisoning in children (36.5%). The age ranged from less than 1 to 18 years and the most vulnerable age group included children from less than 1 year to 6 years. Accidental mode was the most common (79.7%). Intentional attempts were also noticed (20.2%) in the age group above 12 years. The present data may not give an exact picture of the incidence of poisoning in India, but represents a trend in our country. The Poisons Information Centre plays a vital role in providing timely management guidelines including the supply of necessary antidotes from the recently established National Antidote Bank, thereby helping to save precious lives.

Hazards in the home: using older adults' perceptions to inform warning design.

Older adults' perceptions of hazards associated with home product usage and beliefs about product warnings were assessed. Focus group interview data were coded along the dimensions of (a) product type; (b) hazard type; (c) hazard knowledge; (d) hazard avoidance; (e) product warning presence; and (f) product warning necessity. A survey supplemented the focus group results by gathering measures of usage patterns and usability difficulties associated with various types of household products. Older adults reported routine use of products they considered to be hazardous and identified an array of home safety concerns. Furthermore, personal experience was an important source of older adults' hazard knowledge and they described a number of hazard avoidance strategies. These data provide insight into older adults' home safety behaviour and suggest a number of approaches to improving hazard communication and warning design.

Optical response of the cultured bovine lens; testing opaque or partially transparent semi-solid/solid common consumer hygiene products.

This study determines the relative ocular lens irritancy of 16 common partially transparent or non-transparent consumer hygiene products. The irritancy was found by measuring the changes in the sharpness of focus [referred to as the back vertex distance (BVD) variability] of the cultured bovine lens using a scanning laser In Vitro Assay System. This method consists of a laser beam that scans across the lens, and a computer, which then analyses the average focal length (mm), the BVD variability (mm), and the intensity of the beam transmitted. Lenses were exposed to the 16 hygiene products and the lens' focusing ability was monitored over 192 h. The products are semi-solids or solids (e.g. gels, lotions, shampoos). They are categorized into six groups: shampoos, body washes, lotions, toothpastes, deodorant, and anti-perspirant. Damage (measured by > 1 mm BVD variability) occurred slower for the shampoos, especially in the case of baby shampoo. The results indicate that shampoos exhibit the lowest level of ocular lens toxicity (irritability) while the deodorant is the most damaging.
