“…Several practices of hand-held sprayer misuse were documented (Table 2), and were influenced by workers intend to facilitate the walking and handling of the cutting tools. For male workers, this practices often positioned the hand-held sprayer near the scrotum area, which has the highest rate of absorption compared to other areas of the body (Karan et al, 2009;Ngo et al, 2010).…”

The high exposure risks of workers to herbicides in low- and middle-income countries is an important public health concern because of the potential resulting negative impacts on workers' health. This study investigated workers' personal protective equipment (PPE) compliance as a risk mitigation measure; particularly workers who apply herbicides for Working for Water (WfW) - a South African invasive alien vegetation control programme. The study aim was to understand workers' low PPE compliance by analysing their risk perceptions of herbicide use, working conditions and socio-cultural context. Research methods included ethnographic observations, informal interviews, visual media, questionnaires and a focus group. Study results indicated that low PPE compliance persists despite workers' awareness of herbicide exposure risks and as a result of the influence from workers' socio-cultural context (i.e. gender dynamics and social status), herbicide risk perceptions and working conditions (i.e. environmental and logistical). Interestingly, teams comprised of mostly women had the highest compliance rate. These findings highlighted that given the complexity of PPE compliance, especially in countries with several economic and social constraints, exposure reduction interventions should not rely solely on PPE use promotion. Instead, other control strategies requiring less worker input for effectiveness should be implemented, such as elimination and substitution of highly hazardous pesticides, and altering application methods.

“…As a result of damage, there is a dry and itchy skin with susceptibility to various diseases, or completely damaged skin barrier, which is unable to fulfil its defensive function (Atrux-Tallau et al, 2010;Ngo et al, 2010;Klimová et al, 2012;Collota et al, 2013). Many APs can penetrate the skin and be absorbed into the skin.…”

“…Many APs can penetrate the skin and be absorbed into the skin. After they enter the vascular system (lymphatic and/or blood vessels), they can produce systemic effects, and are capable of causing disease elsewhere in the body (Ngo et al, 2010). The ability to be absorbed vary according to physical and chemical properties of the individual pesticide, dose/time of exposure, anatomical site of the body, skin condition, temperature and humidity of outdoors, presence of other material on the skin, and many other factors (Hojerová et al, 2015).…”

“…Discussion: Three major types of the APs-skin interactions may occur from the aspect of health risks: (i) local traumas: ranging from skin irritation through skin rashes and burns to permanent degradation of the skin barrier (skin corrosion); (ii) local/systemic traumas: ranging from skin sensitization through complex immune system (allergic contact dermatitis, mainly eczema) responses to skin cancer; (iii) systemic traumas (Atrux-Tallau et al, 2010;Ngo et al, 2010). Due to insufficient use of appropriate gloves we were not surprised that up to 27 % respondents mentioned skin damage in connection with the application of the APs.…”

As many chemicals, also agricultural pesticides (APs) can be hazardous if not used safely. Under typical working conditions, the majority of exposure to the APs is through the hand-skin. Wearing appropriate gloves should be a standard practice when handling the APs. Unlike professionals, amateurs applying the APs in their gardens or vineyards are not trained for the workplace hygiene. In this survey conducted in the spring 2015 across the Slovak Republic, practices regarding the use of protective gloves were obtained. 520 copies of the "paper-and-pencil" questionnaire were distributed to amateur users and specialized stores selling the APs (return rate of 59 %). A set of ten questions a "closed-ended" or "multiple-choice" type was offered. 75 % of respondents wear gloves when handling the APs. Regrettably, among users wearing gloves, 58 % use the same disposable gloves repeatedly, 67 % wear the reusable gloves from last season, and 53 % do not wash outside of the reusable gloves with detergent before removing them. 30 % of glove users wear all available gloves including absolutely inappropriate materials like fabric and leather, 28 % do not recognize the glove material which they use, 20 % use disposable Latex and 3 % Vinyl and Polyethylene gloves. Only 19 % of glove users wear a material that is generally considered a good choice for handling the APs (7 % Neoprene & Latex, 5 % Neoprene, 5 % Nitrile, and 2 % Butyl rubber). The survey showed the need for better education about adequate protective gloves not only for amateur users but also for retailers selling the APs and protective equipment.

“…Os agrotóxicos podem penetrar no corpo humano através da ingestão, respiração, olhos ou absorção pela pele (THUNDIYIL et al, 2008;VITALI et al, 2009;FARAHAT et al, 2010;NGO;O'MALLEY;MAIBACH, 2010). Quando foi questionado aos agricultores sobre as vias de absorção de agrotóxico pelo ser humano, somente 14% dos entrevistados citaram todas elas.…”

ResumoOs agrotóxicos são considerados um importante fator de riscos para a saúde humana e têm sido objeto de vários estudos, tanto pela sua toxicidade como pela degradação ambiental. Este trabalho teve por objetivo diagnosticar o nível de conhecimento de agricultores da mesorregião do Norte Central do Paraná sobre a utilização segura de agrotóxicos. Para isso utilizou-se um questionário que abordou temas relacionados à intoxicações, uso de equipamento de proteção individual (EPI) e conhecimento sobre bulas e rótulos. Foram entrevistados 100 agricultores filiados às cooperativas da região. Após a análise das respostas, foi possível observar que a maioria dos agricultores fazia o uso incompleto do EPI em suas atividades diárias, ou não o utilizavam como foi constatado em todos os casos de intoxicação. Os termos utilizados nas bulas e rótulos de agrotóxicos não são adequadamente compreendidos pelos agricultores, contribuindo para aumento dos problemas no manuseio seguro desses produtos. O estudo permite concluir que é necessário um processo de capacitação e orientação por parte dos órgãos reguladores e das empresas envolvidas, tais como, empresas de insumos, cooperativas e órgãos de assistência técnica, para que a utilização mais criteriosa dos produtos possa diminuir os riscos à saúde das populações rurais e ao meio ambiente. Palavras-chave: Intoxicação, exposição ocupacional, bulas e rótulos de agrotóxicos AbstractPesticides are considered an important risk factor for human health and have been the subject of several studies, both for its toxicity and environmental degradation. This study aimed to diagnose the knowledge level of farmers from the Central Northern Paraná State on the safe pesticides use. For this we used a questionnaire that addressed issues related to intoxication, use of personal protective equipment (PPE) and knowledge about inserts and labels. We interviewed 100 farmers affiliated to cooperatives in the region. After analyzing the responses, we observed that most farmers did an incomplete use of PPE in their daily activities, or did not use it, as it was found in all cases of poisoning. The terms used in the pesticides inserts and labels are not properly understood by farmers, contributing to increased problems in the safe handling of these products. The study concludes that it is necessary to have a process of training and guidance from regulators and the companies involved, as inputs companies, cooperatives and technical assistance agencies aiming more judicious use of the products and decreasing the risks to health of rural populations and environment.
