Description of key information
ACUTE TOXICITY TO FISH
Weight of evidence: Guideline TG 203, GLP principles followed. Based on available data from National instititute of technology and evaluation (NITE) test item has Lethal concentration LC50 (96h) of 21 mg/L, tested on the fish: Oryzias latipes.
The result of the study, published in the Journal of Hydrology, is evaluated as LC50 (96h) of 20.8 mg/L and 95% confidence interval of 15.7-29.3mg/L, tested on the fish species Pimephales promelas. To the tested substance was assigned the degree of toxicity according the E.P.A., category C.
AQUATIC INVERTEBRATES
Key study:Based on available data from National instititute of technology and evaluation (NITE) test item has Effective concentration EC50 (48h) of 12 mg/L based on mortality for daphnia magna.
