RESUMO
Earthworms, Lumbricus terrestris, exposed in artificial soil to sublethal concentrations of technical chlordane (6.25, 12.5, and 25 ppm) and cadmium nitrate (100, 200, and 300 ppm) exhibited significant reduction in spermatozoa from testes and seminal vesicles. The onset time of reduction varied with exposure concentration, but absolute depression in sperm count was independent of exposure concentration or exposure duration after reduction was first manifested, demonstrating a threshold effect. Earthworm sperm counts show potential as a rapid-measurement endpoint biomarker for measuring sublethal effects of chemical pollutants on reproduction.
