Dioxins and furans in bottom sediments near the 47 Canadian pulp and paper mills using chlorine bleaching / L. Trudel.

Includes bibliographical references (pages 84-88). "Sediment samples collected over the study period were analyzed for dioxins and furans, organic carbon content and particle size distribution. Sediment samples were found to be contaminated by at least one form of dioxin or furan at most of the mill sites sampled. At several sites the level of contamination was high. In general, sediment samples from British Columbia coastal mill sites show higher levels and a more complex mixture of dioxins and furans than inland mill samples. The report recommends changes to the survey design and additional sampling to complete the study's data and permit a definitive evaluation of the level of contamination for each site"--Abstract, page viii.
