Description We analyzed polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) concentrations in suspended particulate matter (SPM) collected from the Columbia River at Northport during 1990, 1992, 1993, and 1994 autumn low-flow conditions. The primary objective was to document the effects of pollution abatement efforts by the Celgar pulp mill in Castlegar, British Columbia, 46 river miles upstream of Northport. We also estimated PCDD/PCDF loads in the river and compared the 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) loads to the target for the watershed north of the international boundary as detailed in EPA’s total maximum daily load (TMDL) for the Columbia River basin.
