Abstract

The effects of dieldrin in food organisms and commercial feed on growth and bioaccumulation were determined in mallard ducklings (Anas platyrhynchos). Dieldrin-fed crickets, mealworms and annelid worms, and dieldrin-spiked commercial feed, were fed to mallard ducklings for 8 days. Mean measured food concentrations (animals plus feed) of <0.2, 2.6, 26.2, and 49.3 μg/g dieldrin did not affect growth after 14 days. Tissue dieldrin concentrations (μg/g wet wt) increased rapidly: up to 80.7 (lipid), 30.1 (skin), 4.1 (liver), 1.8 (muscle), and 1.6 (brain) μg/g. Dieldrin concentrations in tissues were up to 3.7 times greater than in the test diets.
