Key data environmental classification:
Short term aquatic hazard:
Category acute 1: no classification (all acute values > 1 mg/L)
Long term aquatic hazard:
(ii) Readily biodegradable, no bioaccumulation, adequate chronic toxicity data available; no classification (all chronic values > 1 mg/L)
Considering all available data from acute and/or chronic toxicity tests on aquatic organisms and taking into account the provisions laid down in Regulation 1272/2008 CLP (GHS), including ATP 790/2009 and ATP 286/2011, maleic acid does not need to be classified as hazardous to the aquatic environment.
