Description of key information
Trimethyl phosphate has been tested in a limited number of aquatic species (Selenastrum capricornutum, Daphnia magna and Oryzias latipes), under OECD test guidelines [OECD TG 201, 202, 203,].
Various NOEC and LC50 values were gained from above tests:
LC50 = > 1,050 mg/l (acute fish);
EC50 = > 1,000 mg/l (acute daphnia);
EC50 = > 1,000 mg/l (acute algae);
NOEC = 320 mg/l (longterm daphnia reproduction).
Therefore, the chemical is considered to be slightly toxic to daphnids and non-toxic to fish and algae.
Additional information
