Description of key information

The 96-h ErC50 of 1.1 mg/L in Chlorella pyrenoidosa will be used in the assessment.

Key value for chemical safety assessment

Additional information

No growth inhibition tests with algae are available for zinc bis(dibutyldithiocarbamate). The results from the structural analogue zinc diethyldithiocarbamate are used (for details 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 in Chlorella pyrenoidosa from a semi-static non-GLP, OECD 201 guideline study without analytical monitoring (van Leeuwen et al., 1985b) is used in the assessment.
