Abstract:Experiments were conducted with ducks and chickens to determine the effects of acute doses of DDT and DDE on calcium-45 balance and calcium-45 distribution among plasma, femur, tibia, oviduct, shell gland, and eggshell. Species differences in distribution of calcium-45 were evident between control ducks and control chickens. Ducks contained more radiocalcium in plasma, shell glands, tibias, and femurs than chickens and eliminated less radiocalcium in their droppings than chickens. The percentage of radiocalciu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
