Depending on local conditions and existing concentrations, disturbances
in the biodegradation process of activated sludge are possible.
Three studies investigating the toxicity of maleic anhydride to
microorganisms are available. The substance hydrolyses in contact with
water forming maleic acid. Therefore studies on maleic anhydride and the
product of hydrolysis are considered here. As key study a guideline test
performed in compliance with German standard DIN 38412, part 8 was
identified. After 18 hours an EC10 of 44.6 mg/l in Pseudomonas putida
was determined (Hüls America Inc., 1990).
