â¢We studied recovery of post-exposure feeding rates 48-96 h after cadmium exposure.â¢The assay is based on the isopod Cyathura carinata.â¢Post-exposure feeding inhibition is a stable sublethal endpoint.
Post-exposure bioassays are used in environmental assessment as a cost-effective tool, but the effects of organism's recovery after exposure to pollutant has not yet been addressed in detail. The recoveries of post-exposure feeding rates after being exposed to two sublethal concentrations of cadmium during two different exposure periods (48Â h and 96Â h) were evaluated under laboratory conditions using the estuarine isopod Cyathura carinata. Results showed that feeding depression was a stable endpoint up to 24Â h after cadmium exposure, which is useful for ecotoxicological bioassays.
