Abstract: Very little information was available on the degree of accumulation of dimethylamine (DMA) salt of 2,4-dichlorophenoxyacetic acid (2,4-D) by fish and blue crabs. Such knowledge was important to the process of registering 2,4-D in slow moving waters for aquatic plant control. In order to assess the ability of fish to uptake and metabolize 2,4-D, this study was conducted using bluegills and channel catfish under conditions where the microbial degradation of the herbicide in water was minimal. Also, to determine the residues of 2, 4-D in crab-meat, blue crabs were collected from four locations along the St. Johns River in Florida, following treatment of water hyacinths with the 2,4-D DMA. The results of this study demonstrated that the herbicide did not bioaccumulate in fish and did not exceed the established tolerance limit (1.0 ppm) in blue crab flesh.
