Summary, Etc. Note: |
Abstract: The molluscicide Bayer 73, a chemical used as a synergist in conjunction with 3-trifluoromethyl-4-nitrophenol (TFM) to control the sea lamprey in tributaries of the Great Lakes, was tested against five species of crustaceans and two species of aquatic insects: daphnids, aquatic sowbugs, scuds, glass shrimp, crayfish, damselfly nymphs, and midge larvae. All organisms exposed to Bayer 2353 accumulated radioactive residues in 24 hours that ranged from 4 to 80 times (based on wet weight of the whole organism) the water concentration of 1.2 (plus or minus) micrograms/liter. |
