The aquatic toxicity of PTPTT was investigated in acute aquatic
toxicity studies on three trophic levels: algae, invertebrates and fish.
All studies were performed according to OECD guidelines and in
compliance with GLP principles. The aquatic toxicity data indicated that
algae are the most sensitive species, with a 72h growth inhibition ErC50
of 0.45 mg/L for the green algaPseudokirchneriella subcapitata.
For the freshwater fishPimephales promelas, a 96h LC50 of 1.2
mg/L was observed. For the freshwater invertebrateDapnia magna, a
48h EC50 of 0.79 mg/L was observed.
