Summary, Etc. Note: |
Abstract: Samples of water, bottom soil, plants, invertebrates, and fish for residue analysis were collected from two stations on the East Au Gres River in Michigan before, during, and after treatment of the stream with 3-trifluoromethyl-4-nitrophenol (TFM) for control of sea lampreys. The residues were highest in samples collected as the last portion of full-strength TFM flowed past each station, and were much higher in water and organisms than in the bottom soil. FIsh retained higher residues than other organisms 24 hours after treatment; however, the residues decreased to less than 0.08 microgram/gram at 96 hours after treatment. Residues in soil were among the lowest found in all samples collected during the study. |
