POLYCYCLIC AROMATIC HYDROCARBON HAZARDS TO FISH , WILDLIFE , AND INVERTEBRATES : A SYNOPTIC REVIEW By

Abstract

TD3: Contamination of the environment by cadmium, a relatively rare heavy metal, is increasing and is especially severe in the vicinity of smelters and urban industrialized areas. Very low concentrations of cadmium have been implicated as the cause of numerous deleterious effects to fish and wildlife, especially aquatic life. This report briefly reviews ecological and toxicological aspects of cadmium, with emphasis on natural resources, and provides recommendations for the protection of sensitive species of wildlife and aquatic biota. Subtopics include: environmental chemistry; background concentrations in terrestrial and aquatic organisms; toxic and sublethal effects, including bioaccumulation; and teratogenic, mutagenic, and carcinogenic properties.
