Contaminants in the Canadian Arctic: 5 years of progress in understanding sources, occurrence and pathways.
Recent studies of contaminants under the Canadian Northern Contaminants Program (NCP) have substantially enhanced our understanding of the pathways by which contaminants enter Canada's Arctic andExpand

Composition and distribution of polycyclic aromatic hydrocarbon contamination in surficial marine sediments from Kitimat Harbor, Canada.
Surficial marine sediments from 20 sites within the Kitimat fjord system were analyzed for polycylic aromatic hydrocarbons (PAHs). Levels of the sum of the 16 USEPA priority pollutant PAHs variedExpand

Extraction and speciation of arsenic in plants grown on arsenic contaminated soils.
A sequential arsenic extraction method was developed that yielded extraction efficiencies (EE) that were approximately double those using current methods for terrestrial plants. The method wasExpand

On site bioremediation of hydrocarbon-contaminated Arctic tundra soils in inoculated biopiles
Abstract. There is a need to develop technology to allow the remediation of soil in polar regions that have been contaminated by hydrocarbon fuel spills. Bioremediation is potentially useful for thisExpand

Human exposure to organic arsenic species from seafood.
Seafood, including finfish, shellfish, and seaweed, is the largest contributor to arsenic (As) exposure in many human populations. In contrast to the predominance of inorganic As in water and manyExpand

PCBs in sediments and the coastal food web near a local contaminant source in Saglek Bay, Labrador.
Polychlorinated biphenyls (PCBs) were measured in marine sediments and the coastal food web in Saglek Bay, Labrador, to investigate the influence of a local PCB source. Saglek Bay has been the siteExpand

Reduction of PCB contamination in an Arctic coastal environment: a first step in assessing ecosystem recovery after the removal of a point source.
Studies have documented the presence of organic contaminants in Arctic marine environments due to local point sources, but little long-term data is known of the recovery process once thoseExpand

Biostimulation and bioaugmentation for on-site treatment of weathered diesel fuel in Arctic soil
Abstract. Bioremediation of weathered diesel fuel in Arctic soil at low temperature was studied both on-site in small-scale biopiles and in laboratory microcosms. The field study site was onExpand

Biological responses to PCB exposure in shorthorn sculpin from Saglek Bay, Labrador.
A local source of polychlorinated biphenyls (PCBs) in Saglek Bay, Labrador, has contaminated marine sediments and the coastal food web. As part of a larger assessment of ecological risks in the Bay,Expand
