Additional information
The toxicity of zinc bis dimethyldithiocarbamate (CAS No. 137-30-4) to algae species was investigated in three studies. The test chosen as key study (Dobbins et al., 2014) was conducted according to OECD Guideline No. 201, Algae, Growth Inhibition Test (2006), under GLP conditions. Pseudokirchnerella subcapitata was exposed for 72 hours to the test substance and effects on biomass and growth were measured. The resulting ErC50 and NOErC values based on growth inhibition were determined to be 0.0733 and 0.0534 mg a.i./L respectively.
Another study on Pseudokirchnerella subcapitata (Lopes Morandi, 2007) was also conducted according to OECD 201, but the validity of the test was impaired by unreliable analysis of the test material in medium.An additional study conducted according to FIFRA Guidelines 122-2 and 123-2 (1996) for 120 hours is available (Hoberg, 1995). The results from this test are expressed on the basis of algae biomass, resulting in an EbC50 = 0.066 mg a.i./L.
