Additional information

In the assessment a 96-h LC50 value of >10 mg/L is used from a non-GLP, OECD 203 guideline study with the guppy Poecilia reticulata conducted under semi-static conditions without analytical monitoring (Akzo Nobel Research Laboratories, 1991).

No short-term tests are available with Daphnia for zinc bis(dibenzyldithiocarbamate). The results from the structural analogue zinc bis(dibutyldithiocarbamate) are used (for details see Reporting Format as attached to the respective IUCLID entry and CSR Appendix A.1). A 48-h EC50 value of 0.74 mg/L in Daphnia magna from a static GLP-compliant, OECD 202 guideline study without analytical monitoring (Analytical Bio-Chemistry Laboratories Inc., 1983) is used in the assessment.

No growth inhibition tests with algae are available for zinc bis(dibenzyldithiocarbamate). The results from the structural analogue zinc bis(diethyldithiocarbamate) are used (see Reporting Format as attached to the respective IUCLID entry and CSR Appendix A.1). A 96-h ErC50 value of 1.1 mg/L inChlorella pyrenoidosa from a semi-static non-GLP, OECD 202 guideline study without analytical monitoring (van Leeuwen et al., 1985b; van Leeuwen, 1986) is used in the assessment.

An 8-d NOEC value of 100 µg/L inDanio rerio(tested asBrachydanio rerio) from a non-GLP, OECD 204 guideline study with the guppy conducted under semi-static conditions without analytical monitoring (Akzo Nobel Research Laboratories, 1991) is used in the assessment.

No long-term tests are available withDaphniafor zinc bis(dibenzyldithiocarbamate). The results from the structural analogue zinc bis(diethyldithiocarbamate) are used (see Reporting Format as attached to the respective IUCLID entry and CSR Appendix A.1). A 21-d NOEC value of 3.2 µg/L inDaphnia magnafrom a semi-static non-GLP, near guideline study without analytical monitoring (van Leeuwen et al., 1985a; van Leeuwen, 1986) is used in the assessment.
