| 520 | |a"In 1988, a study of the herbicide trifluralin was initiated in two dugouts near Peace River, Alberta. Although trifluralin is considered to be relatively safe, there are uncertainties with respect to its effects on aquatic ecosystems. It can be biomagnified and some metabolites persist adsorbed to soils. Since earlier work has shown that lime treatment can remove particulates from the water column and since most organic contaminates adsorb to particles, lime was evaluated as a treatment technique"--Executive summary. |
