Application of the 1-h acute Ceriodaphnia dubia toxicity test (CerioFAST{trademark}) to environmental samples
- Univ. of Florida, Gainesville, FL (United States). Dept. of Environmental Engineering Sciences
A comparison of the standard acute 48-h Ceriodaphnia dubia bioassay and a rapid acute 1-h Ceriodaphnia dubia toxicity test (CerioFAST{trademark}) was undertaken to determine the toxicity of industrial effluents and process water samples. CerioFAST is based on suppression of feeding activity of Ceriodaphnia dubia in the presence of toxicants and consists of a one-hour exposure period to a given toxicant followed by a 20-min feeding period using fluorescent yeast cells. Twenty-nine industrial effluents and process water samples collected from northern and central Florida and Switzerland were tested and compared using the CerioFAST and the standard 48-h Ceriodaphnia dubia bioassay. The results of the CerioFAST were well correlated with the standard 48-h Ceriodaphnia dubia bioassay (r{sup 2} = 0.98). The authors found out that the CerioFAST was comparable to the standard acute 48-h Ceriodaphnia dubia bioassay and useful as a rapid screening test for environmental samples.
