Rates of Accumulation of 14C-Dieldrin Residues in Tissues of Goldfish Exposed to a Single Sublethal Dose of 14C-Aldrin

Abstract

Immediately after goldfish (Carassius auratus (Linnaeus)) had been exposed for 8 hr in a static system to 0.05 ppm of 14C-aldrin, 14C-dieldrin was detected in various tissues. The percentages that were dieldrin increased with time in all of the tissue studied until at 32 days they were 93.9% or more except for visceral fat. Except in visceral fat, 50 and 100% of the residues were dieldrin within 2.5–5.4 and 31.5–92.4 days respectively. For visceral fat the corresponding times were 46.9 and 14,733 days.
