Uptake and metabolism of dimethylamine salt of 2,4-dichlorophenoxyacetic acid by fish

Bioconcentration and Metabolism of Diclofop-Methyl in Freshwater Fish (Oreochromis niloticus)

“…Recently more attention has been given to tissue-specific contaminant distribution 15,16 . Variability in the bioconcentration factor can, in some cases, be explained by differences in whole body lipid contents among the test animal or species investigated 14,17,18 . The low bioaccumulation of diclofop-methyl in fish muscle might be due to the low amount of lipids in muscle tissue of Oreochromis niloticus fish.…”

2,4-Dichlorophenoxyacetic acid disposition after oral administration in channel catfish

“…After exposure of bluegills and channel catfish to 2,4-D (1 mg/ L) in water for 120 h, residues were not detectable (<0.01 ppm) in the whole body or individual tissues (Rodgers and Stalling, 1972). Bioconcentration also was low during exposure of fish to the dimethylamine salt of 2,4-D (Schultz, 1973; Sikka et al, 1977). The nonpolar butoxyethanol ester of 2,4-D is much more highly absorbed (Rodgers and Stalling, 1972).…”

Effect of gibberellic acid and 2,4-dichlorophenoxyacetic acid on waterhyacinth, Eichhornia crassipes (Mart.) Solms /

“…The rate was dependent upon (1) period of time in which the system has acclimatized to 2,4-D; and (2) the natural condition of the aquatic environment. The various formulations of 2,4-D also do not persist or bioaccumulate in fish (Schultz, 1973;Whitney et al, 1973;Sikka et al . , 1977;Halter, 1980), blue crabs, Callinectes sapidus (Joyce and Sikka, 1977) and benthic invertebrates (Whitney et al, 1973;Halter, 1980).…”
