Organochlorine Pesticides in Wolves from Galicia

Levels of seven organochlorine pesticides (heptachlorepoxide, dieldrin, endrin, p,p′-DDE, o-p′-DDT, p,p′-DDT, and methoxychlor) and DDE/DDT ratios were determined in spleen, liver, muscle, kidney and suprarenal from 12 wolves from three provinces of Galicia (eight male and four female). Analysis was carried out by GC-ECD. Heptachlorepoxide was in found only 25% of samples, while p,p′-DDE was the most dominant of the organochlorine compounds analyzed. DDE/DDT ratios higher than 1 were found in liver and muscle.
