ABSTRACT

INTRODUCTION: The aim of this study was to conduct a systematic literature review to find the association between pesticide exposure and the incidence of suicide in agricultural workers, focusing on analyzing the profile of agricultural workers, the countries with the highest number of publications and, especially, the link between occupational exposure to pesticides, the degradation of mental health and suicide among agricultural workers. METHODS: A systematic literature review was conducted following the PRISMA protocol using Scopus, Web of Science, and PubMed databases, where 33 articles were screened to compose the final portfolio. RESULTS: There is a strong link between pesticide exposure and suicide in agricultural workers. Smoking, alcohol consumption, exposure time, and marital status influence the decision to die by suicide. Brazil and the US lead the ranking in publications, demonstrating that it is not a problem only for developing countries. Organophosphates are the main pesticides used, and they degrade an enzyme crucial for the nervous system, which can result in mental disorders and consequent suicide in agricultural workers. CONCLUSION: There is a need for stricter norms for the commercialization and use of pesticides. There is also a need for providing training to agricultural workers on the application and storage of pesticides, and to communicate about the compounds and the consequences of pesticides to mental health.

ABSTRACT

INTRODUCTION: The aim of this research is fourfold: (i) analyze which countries have the most publications on suicide among agricultural workers, (ii) understand the factors that lead to either suicide or intent, (iii) identify the methods of suicide or attempted suicide, and (iv) propose preventive measures so that rural agricultural workers are not exposed to risk factors to suicide. METHODS: A literature review was conducted for the period 1996-2019; the Scopus, Lilacs, PubMed/MEDLINE, and Science Direct databases were searched, resulting in 44 articles deemed relevant to this research. RESULTS: Agricultural workers were considered to be workers who perform agricultural activities, as either employees or employers. Australia, China, India, and Brazil had the most publications, and the causes of suicide were mostly easy access to or exposure to pesticides, and socioeconomic factors, such as masculinity, conditions of poverty, and social isolation. CONCLUSION: Compared with other workers, agricultural workers can be a group at risk, with a great number of factors leading to suicide. Based on the available literature, proposals for suicide prevention are suggested.

ABSTRACT

The bioeconomy is considered one of the three main sectors with the greatest opportunities for the development of the circular economy in Brazil, who is one of the largest silk producers in the world; and sericulture is an agribusiness that contributes greatly to the bioeconomy in Brazil. Therefore, this research aimed to identify opportunities for creating value by internalizing flows in the production of silk cocoons by promoting a circular bioeconomy. To that end, a tool was used to assess the circularity of the referred system. The current circularity of the production of silk cocoons, at the farm level, is 74.19 % for material, and 0 % for energy. A range of measures are proposed, based on (i) engaging with reverse logistics practices, (ii) establishing a local agroindustrial cooperative, and (iii) building community biodigesters, which aid a potential circularity of 85.51 % (material), and 100 % (energy) at the farm level, and 98.42 % (material) and 100 % (energy), at the cooperative level. On top of increasing circular value, the proposed measures might bring environmental benefits, such as lessening environmental impacts of logistics (by valuing local resources) and replacing non-renewable energy, and social impacts, through increased quality of life for sericulturists. Economic implications need further investigation and are suggested to be addressed in future research endeavors, along with policy implications for the development of a circular bioeconomy. Furthermore, an increased circularity can also contribute to a few of the sustainable development goals (SDGs) proposed by the United Nations, such as SDGs 2, 7, 9, 11, 12 and 13.

ABSTRACT

The purpose of this study was to validate the construct and reliability of an instrument to assess the work environment as a single tool based on quality of life (QL), quality of work life (QWL), and organizational climate (OC). The methodology tested the construct validity through Exploratory Factor Analysis (EFA) and reliability through Cronbach's alpha. The EFA returned a Kaiser-Meyer-Olkin (KMO) value of 0.917; which demonstrated that the data were adequate for the factor analysis; and a significant Bartlett's test of sphericity (χ² = 7465.349; Df = 1225; p ≤ 0.000). After the EFA; the varimax rotation method was employed for a factor through commonality analysis; reducing the 14 initial factors to 10. Only question 30 presented commonality lower than 0.5; and the other questions returned values higher than 0.5 in the commonality analysis. Regarding the reliability of the instrument; all of the questions presented reliability as the values varied between 0.953 and 0.956. Thus; the instrument demonstrated construct validity and reliability.

ABSTRACT

The sustainability of a biofuel is severely affected by the technological route of its production. Chemical pretreatment can be considered the traditional method of decomposition of the lignocellulose into its mono and oligomeric units, which can be further bioconverted to ethanol. The evaluation of the recent advances in chemical pretreatments of sugarcane bagasse, especially diluted acids, alkaline, organosolv and ionic liquids, identified the critical points for sustainability. In this context, chemicals recovery and reutilization or their substitution by green solvents, heat and electricity generation through bioenergy, reutilization of water from evaporators, vinasse concentration and the upgrading of lignin were discussed as strategic routes for developing sustainable chemical-based lignocellulose pretreatment. The advances in the technologies that allow greater fractionation of lignocellulosic biomass should be focused on the minimization of the use of natural resources, effluent generation and energy expenditure.

ABSTRACT

Brazil is one of the largest producers of medium-density fibreboard (MDF) in the world, and also the MDF has the highest domestic consumption and production rate in the country. MDF applications are highlighted into residential and commercial furniture design and also a wide participation in the building sector. This study aimed to propose ways of improving the environmental cradle-to-gate life-cycle of one cubic meter MDF panel by means of a life-cycle assessment (LCA) study. Complying with requirements of ISO 14040 and 14,044 standards, different MDF manufacturing scenarios were modelled using Umberto® v.5.6 software and the Ecoinvent v.2.2 life-cycle inventory (LCI) database for the Brazilian context. Environmental and human health impacts were assessed by using the CML (2001) and USEtox (2008) methods. The evaluated impact categories were: acidification, global warming, ozone layer depletion, abiotic resource depletion, photochemical formation of tropospheric ozone, ecotoxicity, eutrophication and human toxicity. Results identified the following hotspots: gas consumption at the thermal plant, urea-formaldehyde resin, power consumption, wood chip consumption and wood chip transportation to the plant. The improvement scenario proposals comprised the following actions: eliminate natural gas consumption at the thermal plant, reduce electrical power consumption, reduce or replace urea-formaldehyde resin consumption, reduce wood consumption and minimize the distance to wood chip suppliers. The proposed actions were analysed to verify the influence of each action on the set of impact categories. Among the results, it can be noted that a joint action of the proposed improvements can result in a total reduction of up to 38.5% of impacts to OD, 34.4% to AD, 31.2% to ET, and 30.4% to HT. Finally, MDF was compared with particleboard production in Brazil, and additional opportunities to improve the MDF environmental profile were identified.

ABSTRACT

This study aims to analyze the syntax of the World Health Organization's quality of life HIV/AIDS instrument (WHOQOL-HIV), provided by the WHOQOL-HIV Group. As a result, errors and inconsistencies in the syntax of WHOQOL-HIV were found. In face of the fragility found, two new syntaxes for WHOQOL-HIV were proposed: (a) a correction of errors found in the original syntax; and (b) restructuration of the calculation of scores for WHOQOL-HIV, bringing it closer to the WHOQOL-100. Through the Statistical Package for the Social Sciences software, the syntaxes proposed were tested and compared to the syntax of the original WHOQOL-HIV. It was noted that both proposals met their respective purposes. They were also sent to researchers on the theme under consideration to verify the presence of errors. No irregularity was found. It can be concluded that the syntax of the WHOQOL-HIV differs significantly from the syntax of its precursor, the WHOQOL-100, presenting errors and inconsistencies. The differences observed compromise the fidelity of the instrument under consideration and, therefore, it is here commended the use of the syntax proposed in this study, which offers superior precision to portray the empirical reality of quality of life in human immunodeficiency virus positive people.
