Additional information

As key study concerning acute toxicity to microorganisms a test performed by BASF (1988) according to German Industrial Standard DIN 38412 part 27 was identified, using Pseudomonas putida as test organism. In the static test a NOEC >= 10 mg/L after 30 minutes of exposure was calculated.
