Factors in the accumulation of dieldrin in broiler organs: doses administered with feed; dose-organ-dieldrin accumulated relationship; toxicological consequences.

The quantity of dieldrin accumulated in liver, kidney, heart, gizzard, lung, muscle, and intestine with contents, of broiler chickens fed with feed contaminated by this insecticide, was determined by gas chromatography analysis. The doses used were 60, 90, 120, 200 and 240 ppm. The influence of the doses used in the quantity of dieldrin accumulated in the different organs, the relationship between the doses administered, organs and quantity accumulated, and the toxicological consequences of the contamination were studied. The results show that the doses used did not significantly affect the quantity of dieldrin accumulated by the different organs. The relationship doses-organ-quantity accumulated shows that the muscle accumulates equal dieldrin at all the doses used. The differences in the dieldrin accumulated at different doses increases with the metabolic function of the organs. The principal symptoms of intoxication were anorexia, convulsions and tremors, which indicated that the nervous system is a major site of activity.
