Polycyclic aromatic hydrocarbons, organic carbon and nitrogen content of wastewater suspended solids : data summary report / by: George Derksen.: En84-223/1997E-PDF
"The Fraser River Action Plan, a six-year basin-wide program, was initiated in 1991 to assess the condition of the river (FRAP, 1892). Determining the quality and quantity of wastewater discharges and estimating contaminant loadings was a component of Environmental Protection Branch's contribution to the program. Polycyclic aromatic hydrocarbons (PAHs), because of their low aqueous solubilities, entering the aquatic environment rapidly become adsorbed to organic and inorganic particulate matter (Neff, 1979, Nagpal 1993). Depending on the octanol-water partition coefficient Kow, which provides a direct estimate of partitioning tendency from water to organic media, the higher Kow compounds would expected to be largely found associated with the organically rich and fine suspended matter in some wastewaters. PAHs may adsorb to either inorganic or organic surfaces although adsorption to organic materials predominates (NRC,1983). Merriman, 1988 identified PAHs associated with centrifuged pulp mill effluent suspended solids but not in the centrifuge-clarified water fraction. Dunn and Stich, 1976 identified a sharp gradient of benzo(a)pyrene [B(a)P] in sediment samples toward the lona Island sewage treatment plant (STP) outfal). They concluded the STP was the major contributor to the Fraser River estuary PAH burden. Several high molecular weight PAHs (e.g., B[a]P) are of particular environmental interest as they are known to be carcinogenic (Nagpal, 1993)"--Introduction.
