Resumen

SANCHEZ, Victoria Guadalupe et al. Organophosphate and carbamate pesticide residues in drinking groundwater in the rural areas of Plottier and Senillosa, North Patagonia, Argentina. Acta toxicol. argent. [online]. 2016, vol.24, n.1, pp.48-57. ISSN 1851-3743.

Plottier and Senillosa are two adjoining towns that belong to the agricultural production area of Upper Valley, Río Negro and Neuquén, North Patagonia. Among the most widely used pesticides, neonicotinoids, carbamates and organophosphates are predominant. The levels of these compounds in surface and groundwater have become a topic of public concern, since the possible impact on health and environment. The aim of this study was the determination of pesticide residue levels in drinking ground-water in the rural areas of Plottier and Senillosa. Carbamates: propoxur, carbofuran, pirimicarb, carbaryl and organophosphate: chlorpyrifos, dimethoate, methidathion, fenaminfos, triazophos, phosmet, azinphos methyl, were analyzed by GC in six sampling sites during insecticide application and non-application season. No pesticide residues were detected by the analytical method used. The detection limit for organophosphates was 0.010 µg/L and 0.030 µg/L for carbamates. These results indicate that good agricultural practices, the physicochemical characteristics of the soil, its thickness, the content of organic matter and the physicochemical properties of pesticides studied are factors that positively contribute to the drinking water quality in the rural population.
