520 |a"The distribution of 2,4-D in the Red River between Emerson and Netley Lake was studied. The herbicide was found primarily in the water, less on the suspended sediment and not detectable in the bottom sediments and benthos. The recorded high concentration of 2,4-D in February 1977 that prompted this study is believed to be derived in part from the effluent of the City of Winnipeg's North End Pollution Control Center, which was found to contain 30 500 ng/L, 2,4-D. There is no measurable accumulation of 2,4-D in the deposited river sediment. This report also addresses (1) the variability of 2,4-D concentrations attributed to the sampling technique, (2) the river cross-sectional heterogeneity and (3) the sample preservation technique"--Abstract, p. v.
