Recommendations of a workshop on biological screening requested the inclusion of behavior studies to reveal subtle, dysfunctional effects of pollutants on organisms and suggestions for additional research in development of behavioral tests incorporated into testing protocols were made at the ASTM Symposium on Aquatic Toxicology. The present study addresses these research needs by examining a rapid behavioral bioassay using protozoa, microfauna with important roles in microbial-based food chains, regeneration of nutrients, and regulation of bacterial populations in aquatic environments. In this study, ciliated protozoa from both marine and freshwater environments were examined with respect to their response to an attractant in the presence of a variety of concentrations of cadmium and copper.
