Principal components analysis (PCA) has been applied to a large data set of the concentrations of chlorinated dibenzo-p-dioxins and dibenzofurans in samples of crab hepatopancreas from British Columbia, Canada (B.C.). These samples have been collecte

Mill process changes and source controls instituted in the late 1980s at pulp and paper mills along the British Columbia (BC) coast produced dramatic reductions in both the concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F

To study the largest source of river sediment to the Arctic Ocean, we have collected suspended particulates from the Mackenzie River in all seasons and sediments from the Mackenzie shelf between the river mouth and the shelf edge. These samples have

The question of polycyclic aromatic hydrocarbon (PAH) bioavailability and its relationship to specific PAH sources with different PAH binding characteristics is an important one, because bioavailability drives PAH accumulation in biota and ultimately

Six pulp mills using chlorine bleach discharge effluent into the Strait of Georgia. British Columbia Fisheries were closed around the mills when dioxins and furans were measured in sediments and edible seafood. We report here the first measurements m

The identity and form of dissolved organic matter in rivers and oceans are fundamental to the biogeochemical cycle of carbon. In particular, understanding the phase distribution of hydrocarbon compounds is a prerequisite to predicting the transfer be
