Organochlorine pesticides were found in all samples of livers, kidneys, mammary glands and fetuses of eastern water rats (Hydromys chrysogaster) collected in the Murrumbidgee irrigation areas of New South Wales in 1970 and 1972. DDE, an insecticide, was the predominant residue. Livers contained 0.01-3.10 ppm .SIGMA. DDT air-dried weight; kidneys, < 0.01-1.12 ppm; mammary glands, 0.14-23.75 ppm; and fetal liver, 0.28-0.66 ppm. Variations in residue levels are discussed in relation to the possible effects of environmental and physiological factors.
