Bioconcentration of haloxyfop-methyl in bluegill (Lepomis macrochirus rafinesque)

open access: yesEnvironment International, 1990
Bluegill (Lepomis macrochirus Rafinesque) were exposed to a {sup 14}C haloxyfop-methyl (methyl 2-(4-((3-chloro-5-(trifluoromethyl)-2-pyridinyl)oxy)phenoxy)propanoate) concentration averaging 0.29 {mu}g/L under flow-through conditions for 28 days. At the end of 28 days, the fish were transferred to clean water for a 4-day flow-through clearance period ...
