Additional information

There are several valid studies available for the assessment of the toxicity of 3-pentanone to microorganisms. As key study a test on Pseudomonas putida performed by BASF (1988) was identified. This test was performed according to German Industrial Standard (DIN) 38412 part 8. After 17 hours test duration an EC10 of 6287 mg/l was detected for the nominal concentrations.
