Includes bibliographical references (page 13). "The Fraser River Action Plan, a six-year basin-wide program, was initiated in 1991 to assess the condition of the river (FRAP, 1992). Determining the quality and quantity of wastewater discharges and estimating contaminant loadings was a component of Environmental Protection Branch's contribution to the program. Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) are ubiquitous environmental contaminants and have recently received a great deal of research attention in determining their sources and impacts (Dioxin'95, 1995; BCMELP, 1995a). Pulp mills in the mid-1980s were identified as significant sources of dioxins and furans. Loadings from that source and the associated environmental contamination have been shown to have decreased appreciably since the implementation of new regulations and the substitution of elemental chlorine with chlorine dioxide in the bleaching process (BCMELP, 1994; BCMELP, 1995b)"--Introduction.
