Aldrin and dieldrin residues in human fat, milk and blood serum collected from Delhi.

Abstract

1. Aldrin and dieldrin residues were monitored in the fat, breast milk and blood serum from female residents of Delhi. 2. The average aldrin and dieldrin contents were 0.048 and 0.099 ppb in adipose tissue, 0.003 and 0.060 ppb in breast milk and 0.004 and 0.002 ppb in blood serum, respectively. 3. The older donors contained higher levels of aldrin and dieldrin in their adipose tissue. 4. Primagravidae contained more of these chemicals in their breast milk. 5. A positive correlation was observed between the aldrin concentration in adipose tissue and breast milk, and that in adipose tissue and blood serum. Similarly, a significant correlation was found between dieldrin in adipose tissue and blood serum. 6. The levels of aldrin and dieldrin were low in samples from residents of Delhi when compared to those in developed countries.
