Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Three short-term toxicity studies with freshwater fish are available for zinc bis(dibutyldithiocarbamate). A non-GLP, OECD 203 guideline study with the guppy Poecilia reticulata is available (Akzo Nobel Research Laboratories, 1991). The test is semi-static without analytical monitoring. The 96-h LC50 value is >16 mg/L.
Another study is available with the rainbow trout (Oncorhynchus mykiss tested as Salmo gairdneri)( Analytical Bio-Chemistry Laboratories, Inc., 1983a). The study is a static GLP-compliant, EPA-660/3-75-009 guideline study without analytical monitoring. The 96-h LC50 value is 520 mg/L.
A third study is available with the bluegill sunfish (Lepomis macrochirus)( Analytical Bio-Chemistry Laboratories, Inc., 1983b). The study is a static GLP-compliant, EPA-660/3-75-009 guideline study without analytical monitoring. The 96-h LC50 value is 880 mg/L.
The study with Poecilia reticulata is the most critical study and will therefore be used in the assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
