With high probability acutely not harmful to aquatic invertebrates.
Considering the toxicity of
N,N-dimethylacetamide to aquatic invertebrates there are experimental
data from two studies for each, the freshwater and marine compartment
- In a static test conducted according
to EU method C.2., using D. magna as test organism, a 48-h EC50 of >500
mg/L was determined, based on nominal test concentrations (BASF AG,
1988; report no. 1/1021/2/88-1021/88). These data were selected as
- In a supporting acute toxicity test
(guideline not specified in study report) with D. magna as test
organism, the 48-h EC50 was >1000 g/L (nominal, Adema, 1987; cited in
OECD SIDS, 2001).
- A semi-static acute toxicity test
(guideline not specified in study report) was conducted using
Americamysis bahia (former: Mysidopsis bahia) as test organism. Based on
nominal test concentrations the 96-h EC50 was found to be 966 mg/L
(Adema, 1987; cited in OECD SIDS, 2001). These data were selected as
- In a further acute toxicity test
conducted under marine conditions (guideline not specified in study
report) the test organism was chaetogammarus marinus. After an exposure
period of 96 h the EC50 was determined to be >1000 mg/L, supporting the
results of the marine key study (Adema, 1987; cited in OECD SIDS, 2001).
In conclusion, the substance is assessed
to be with probability acutely not harmful to aquatic invertebrates.
