Bowman et al (1981) reported an 18-hour EC50 value of 6530 mg/L for
acetonitrile in Scud, (Hyalella azteca).
According to the Integrated Testing Strategy for toxicity to sediment
dwelling organisms (Guidance on Information Requirements and Chemical
Safety Assessment, chapter 7b, figure 7.8.8) no sediment testing is
necessary for a substance with a log Kow <3. Further
testing on the toxicity of acetonitrile to sediment organisms is
therefore not justified, and the partitioning method can be adequately
used to predict the PNEC for the sediment compartment. Bowman et al
(1981) reported an 18-hour EC50 value of 6530 mg/L for acetonitrile in Hyalella
azteca (Scud), however due to limited information being available on
the study, this data is not considered reliable and is therefore
