Determination of tetrachloroethylene bioconcentration in Unio Complaneteus using SPME and GC-ECD
MetadataShow full item record
Tetrachloroethylene (also known as perchloroethylene or PCE) is a harmful, organic solvent. It has been documented as an environmental pollutant in many public drinking water supplies. The long-term effects of the chemical are still unknown. It has been suggested that PCE does not bioconcentrate in fish or other aquatic organisms. This experiment showed that PCE does bioconcentrate at low levels (5-50ppb) in freshwater mussels. This experiment also suggests that there is a threshold of tolerance for PCE in freshwater mussels.
