CHAGAS, Cíntia Maria et al. Determination of organochlorinated present in river from the region of Viçosa, MG. Quím. Nova [online]. 1999, vol.22, n.4, pp.506-508. ISSN 0100-4042.

In this work the contamination, by organochlorinated, of a drinking water source located in the region of Viçosa, MG, was evaluated. The identification and quantification of the analytes was carried out using a gas-chromatograph equipped with an electron capture detector after liquid-liquid extraction and concentration. Four insecticides, Aldrin, Epoxy heptachloride, Endrin and op'- DDT were detected in concentrations that are higher than the safety limits established in the Brazilian legislation.

Keywords : drinking water quality; organochlorinated pesticide; pesticide analysis; gas-chromatography.
