||The effects of dieldrin in food organisms and commercial feed on growth and bioaccumulation were determined in mallard duckling. 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 microgram/g dieldrin did not affect growth after 14 days. Tissue dieldrin concentrations (microgram/g wet wt) increased rapidly: up to 80.7(lipid), 30.1(skin), 4.1(liver), 1.8(muscle), and 1.6(brain) microgram/g. Dieldrin concentrations in tissues were up to 3.7 times greater than in the test diets.
