Data derived from SIDS Initial Assessment Report For SIAM 16 (Triethyl Phosphite), 2003 Paris.

Concerning the toxicity of triethyl phosphite towards aquatic species, reliable experimental results of short term tests with fish, daphnia, and algae are available. The following concentrations are given for triethyl phosphite and are estimations based on the reported results for diethyl phosphite. The acute toxicity determined for fish (Brachydanio rerio) was 251.66 mg/l (96 h LC50) and for daphnia (Daphnia magna) 94.1 mg/l (24 h-EC50). In the growth inhibition test (72 h) with algae (Scenedesmus subspicatus) an EC50 > 73.6 mg/l was determined for both growth rate and biomass.
