The NOEC of the test item was determined to
be 125 mg/kg SDW based on reproduction. The EC50-value for reproduction
was determined to be 250 mg/kg SDW. The calculated LL50 from TLM QSAR
towards E. fetida is 98.649 mg/kg soil dw and NOELR is 18.898
mg/kg soil dw.
effect of DCPD on earthworm reproduction was determined in a
GLP-compliant study following OECD guideline 222. Earthworms were
exposed to 6 concentrations of DCPD alongside a control in artificial
soil. There were no statistically significant differences in earthworm
reproduction in the treatment rates 15.6 to 125 mg DCPD/kg SDW compared
to the control. However, at the test item concentration 250 mg DCPD/kg,
the earthworm reproduction was statistically significantly reduced and,
at the test item concentration 500 mg DCPD/kg soil dry weight, no
juveniles were found. Overall, the NOEC of the test item concerning
mortality, biomass and reproduction was determined to be 125 mg DCPD/kg
SDW and based on reproduction. The EC50 value for
reproduction was determined to be 250
