Abstract

KLEIN, Bianca N et al. Impact analysis of the use of organophosphates and carbamates rural workers of the municipality in a northwest region of Rio Grande do Sul. Acta toxicol. argent. [online]. 2018, vol.26, n.3, pp.104-112. ISSN 1851-3743.

Annually millions of rural workers are intoxicated in the world, and of these, more than 20,000 die as a result of exposure to pesticides. Intoxication by insecticides organophosphate (OF) and carbamates (CAR) represent the greatest threats to the health of rural workers. OF CAR and act on the inhibition of cholinesterase enzyme, thus inhibition of this proves to be an excellent indicator of the severity of the intoxication. The objective of this study was to analyze the impact of using OF CAR and in rural workers in the city of Mato Queimado/RS. A cross-sectional, prospective and experimental study was conducted. Twenty-three rural workers exposed were investigated. Sample collection and data demographic were conducted in February and March 2014. The cholinesterase activity was determined by biochemical kinetic colorimetric method. The average age of participants was 34.6 years (± 8.5). The most prevalent form of contact is via the application of the product (88.9%). The mean duration of exposure was 10.7 years. Still, 70.4% reported using personal protective equipment (PPE), more frequent use of mask (55.5%). The average values for cholinesterase was 3244.45 U/l (± 345.8) levels below those of the reference. The results obtained in this study are essential to use biological monitoring means of rural workers in purpose of prevention and health promotion.
