LUCERO, Patricia; NASSETTA, Mirtha  and  DE ROMEDI, Adriana. Assessment of environmental exposure to persistent organic pesticides in two neighborhoods of the province of Córdoba. Acta toxicol. argent. [online]. 2008, vol.16, n.2, pp.41-46. ISSN 1851-3743.

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.
