Abstract
Black ducks, Anas rubripes, were exposed to dietary toxaphene concentrations of 0, 10, or 50 μg/g of food for 90 days prior to laying and through the reproductive season. Toxaphene did not affect reproduction or survival, but reduced growth and impaired backbone development in ducklings. Collagen, the organic matrix of bone, was decreased significantly in cervical vertebrae of ducklings fed 50 μg/g, and calcium conentrations increased in vertebrae of ducklings fed 10 or 50 μg/g. The effects of toxaphene were observed only in female ducklings. In contrast to effects on vertebrae, toxaphene exposure did not alter tibia development. Toxaphene residues in carcasses of these ducklings averaged slightly less than the dietary levels.
