Evaluación de la exposición ambiental a plaguicidas orgánicos persistentes en dos barrios de la provincia de Córdoba

organochlorine pesticides were analyzed in 167 samples of whole blood colleted from people from two different sites in the province of córdoba (site no 1 and site no 2). these sites were close to unused pesticides store. the presence of pesticides was determined by gas-chromatography with electron-capture detection using capillary columns. p,p'-dde, β-hch and hcb were the most frequently pesticide detected. the highest concentration found was 7,31 μg/l of p,p'-dde. β-hch showed highest values than its two isomers. as expected, significant relationship was found between the level of p,p'-dde and the age, since the former is a persistent and bioacumulative compound. this paper shows the organochlorine pesticides levels in a population with environmental exposure.
