Summary, Etc. Note: |
Abstract: Residues of 3-trifluoromethyl-4-nitrophenol (TFM) in muscle tissue of eight species of fish, after they were exposed under controlled conditions, were determined by gas chromatography. The mean concentration of TFM residue in samples from various species immediately after a 12-hour exposure to 1 to 4 mg/liter of TFM ranged from 0.02 to 5.09 microgram/gram depending on pH, temperature, hardness of the test solutions, and TFM concentration. Residues decreased rapidly after the fish were withdrawn from the test media, and were near the limit of detection (0.01 microgram/gram) within 24 hours. |
