Additional information

One guideline conform fish test (EPA OPPTS 850.1075) is available for NBPT (Ward and Boeri, 1990). Bluegill sunfish (Lepomis macrochirus) were tested in a 96 h acute dose-response toxicity test at nominal concentrations of 0, 700, 1100, 1800, 3000 and 5000 mg/L under static conditions in accordance with GLP-requirements. The resulting LC50(96 h) was 1140 mg/L based on nominal concentrations.
