OECD Guideline 209, GLP, key study, reliability 2:- 30-min EC50 = 12400 mg/L
reliable study is available to assess the toxicity of the test substance
on aquatic microorganisms. In a 30 min acute toxicity test, according to
OECD Guideline 209 with GLP statement, activated domestic sewage sludge
were exposed to the test substance at nominal concentrations of 1000,
1800, 3200, 5600, and 10 000 mg/L. 3, 5-dichlorophenol was used as
reference material. The 30min-EC50 value was determined at 12400 mg/L
based on nominal concentrations. The reference substance resulted in a
EC50 of 14 mg/L which belongs to the acceptable range.
is classified as acceptable and satisfies the guideline requirements for
toxicity to microorganisms study with activated sludge.
