Description of key information

Based on acute aquatic results for methylenbis(dibutyldithiocarbamate) daphnia magna are the more sensitive species. Chronic testing is available with the most sensitive species daphnia magna. Therefore, chronic testing of fish is being waived.

Key value for chemical safety assessment

Additional information

Upon review of the methylenbis(dibutyldithiocarbamate) acute ecotoxicity data, the NOEC results to aquatic invertebrates (0.052 mg/l) and fish (0.06 mg/l),Daphnia magnaare considered the most sensitive species in terms of aquatic testing. To avoid unnecessary testing the most sensitive species can be chosen as the most appropriate species for long term testing. According to Column 2 of Annex IX of the European Union (EU) Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) 1907/2006 regulation the choice of appropriate testing depends upon the results of the chemical safety assessment. Based on acute aquatic results for methylenbis(dibutyldithiocarbamate)daphnia magnaare the more sensitive species and thus will yield sufficient conservative results to quantify the potential hazards of the test substance while also providing an appropriate hazard assessment. Chronic testing is available with the most sensitive speciesdaphnia magna, therefore, chronic testing of fish is being waived.
