Abstract Peatland waters of the Moose River basin, as well as surficial sediments and vascular plants of the estuary were sampled in 1982. Elevated levels of PCBs were found at all five peatland sites; concentrations ranged from 28 to 65 ng/L. Of the seventeen organochlorine pesticides investigated, the hexachlorocyclohexane isomers (a-and y-BHC) were the most prominent with total BHC concentrations ranging from 1.5 to 13.7 ng/L. The presence of these contaminants in ombrotrophic bogs indicated that there was atmospheric deposition of organochlorine contaminants in the basin. Analyses of surficial sediments, collected from tidal flats and coastal marshes, showed that PCBs and organochlorine pesticides were not present. Samples of Triglochin maritima L. seed heads and Typha latifolia L. roots were also free of PCBs.

Remediation Of Soil

The objective of this study is to quantify the effects of humic acid solution infiltration on the transport of organochlorine pesticides (OCPs) in soil columns using a three-phase transport model. From experimental results, it is found that the dissolved organic carbon enhances the transport of OCPs in the soil columns. In the OCPs-only column, the concentration profiles of OCPs can be simulated well using a two-phase transport model with numerical method or analytical solution. In the OCPs-DOC column, the migrations of aldrin, DDT and its daughter compounds are faster than those in the OCPs-only column. The simulation with the three-phase model is more accurate than that with the two-phase model. In addition, significant decrease of the fluid pore velocities of the OCPs-DOC column was found. When DOC leachate is applied for remediation of soil or groundwater pollution, the decrease of mean pore velocities will be a crucial affecting factor.
