Abstract At a concentration of approximately one hundredth and one thousandth of the 48-hr LC50 values, the accumulation of radioactivity and relative concentration of 2,4-D and glyphosate in carp and tilapia were studied by using labelled and unlabelled chemicals. About 83 (at a concentration of 0.5 ppm) and 91% (of 0.05 ppm) of the radioactive matter remained in the water until 14 days after 14C-2,4-D amended, but only 17.2% of glyphosate remained in the water with 0.05 ppm concentration of glyphosate. No significant variation was shown in the accumulation of the concentration of herbicide in fish from 2 to 7 d. Although glyphosate disappeared within 3 d in water under sunlight, the radiochemicals in the water hyacinth remained constant to the 14th d.
