Toxicity testing with the collembolans Folsomia fimetaria and Folsomia candida and the results of a ringtest

Table 4 Control mortality and reproduction and toxicity endpoints of the ringtest in terms of LC10, LC50, EC10 and EC50 estimated from the complete concentration-response data of each test. Missing cells is due to no effects detected or 50% effect levels outside the concentration range. C.V.: Coefficicient of variability of the control reproduction.
