analysis in the Mackenzie Basin, Northwest Territories.
Such conditions could account for mixing and higher accumulation of contaminants such as total dioxins and furans at sediment station 12 and chromium in oysters in shellfish dredge tract 16.
Louis Bay (11.41 and 11.78 pg/g sediment dry-weight basis) were located at sediment stations 2 and 3, respectively, which were the stations closest to the titanium dioxide refinery effluent outfall point, labeled as a sewer on National Oceanic and Atmospheric Administration (NOAA) Nautical Charts 11371 and 11372A and in Figure 2 and Figure 4.
Average LHC/SHC ratio obtained in this study ranged between 11.18 and 17.71 in the 4 sediment stations
, an indication of a significant input from terrestrial plant waxes.
Louis Bay in our study were from sediment sites 2 and 3, the two sediment stations
located closest to the plant outfall site.
All other sediment stations
were in agriculturally dominated area of the watershed and where taken in close proximity to the sampled fields for which the P-index was determined.
Shown in Figure 2 are the final locations of precipitation, runoff, and sediment stations
. The base precipitation measuring network was operated in the 168-station configuration from September 1961 until October 1986.
