Organochlorine pesticide residues in animals of Tasmania, Australia-1975-77

Abstract

Animals taken in Tasmania including duck (Anas superciliosa), eel (Anguilla australis), English perch (Perca fluviatilis), white-faced heron (Ardea pacifica), brown trout (Salmo trutta), European starling (Strunus vulgaris), cat (Felis cattus), cormorant (Phalacrocorax sp.), mutton bird (Puffinus tenuirostris), Tasmanian devil (Sarcophilus harrisii), rainbow trout (Salmo gairdnerii), Tasmanian raven (Corvus mellori), tench (Tinca tinca), and quail (Coturnix sp.) were sampled for p,p'-DDE, pp,p'-TDE, p,p'-DDT, lindane, dieldrin, and hexachlorobenzene. Pesticide residue levels exceeded 0.1 ppm in at least one animal from each area and in the majority of animals sampled from all areas. Pesticide sources could not be determined, partly because migratory species such as ducks, mutton birds, cormorants, and eels may have ingested pesticides outside of Tasmania.
