Uptake of DDT from the yolk sac into the early chick embryo as measured by gas chromatography.
Bull Environ Contam Toxicol 1981 Jul; 27(3):393-396
The incorporation of DDT (50293) into chick embryos was investigated. Fertile eggs from white Leghorn-chickens received 5 to 20 milligrams each of DDT into the yolk sac. Eggs were incubated for 5 days and embryos were removed. DDT concentrations were determined in yolks and embryos. At all doses, the majority of pesticide was within the confines of the yolk sac. All treated embryos contained DDT at concentrations from 2.1 to 2.8 parts per million. The authors conclude that DDT can be incorporated from the yolk sac to the chick embryo, and the amount of incorporation does not differ significantly with increases in dose.
