A Review of the Toxicological Studies with Polychaetous Annelids
Abstract:A total of 48 species in 20 families of polychaetes have been used as test organisms in assessing the effects of toxicants in the marine environment. Members of families Capitellidae, Dinophilidae, Dorvilleidae and Nereidae are the most commonly used species. Tests conducted include 1) acute, in which survival is the criterion; 2) chronic, in which some biological measure, such as growth, is used; and 3) life-cycle tests in which reproduction and the number of offspring produced are the criteria. Toxicants studied include metals, petroleum hydrocarbons, detergents, pesticides, contaminated sediments and radiation. Laboratory cultures have facilitated the testing procedures, especially for the chronic and life-cycle test. The published literature on the effects of toxicants on polychaetes is reviewed by contaminant, and then summarized in tabular forms.
