Sublethal toxicity of copper to a soil-dwelling springtail (folsomia fimetaria) (collembola: isotomidae)

摘要

The collembolan Folsomia fimetaria was exposed to a range of elevated copper (Cu) concentrations in a LUFA-Speyer soil for 7, 14, and 21 d, in a microcosm test. The results showed that F. Fimetaria was sensitive to copper, with reproduction being a more sensitive parameter of effect than either growth (measured as final body size) or survivorship. A 10/100 effective concentration (EC10) of 38 mg Cu/kg was calculated for reproduction, and an EC10 between 509 to 845 mg Cu/kg (depending on sex and developmental stage) was calculated for growth.
