Yunker ... [et al.]. Vancouver, B.C. : Environment Canada, 2000. xv, 127 p. : graphs, tables, figures. Technical report (Fraser River Action Plan (Canada)) ; DOE FRAP 2000 "February 2000." Includes bibliographic references. Natural and anthropogenic hydrocarbons which enter surface waters both directly from runoff and discharges and indirectly from atmospheric deposition and exchange are efficiently adsorbed onto suspended particulate matter and sediments. The quantities and relative proportions of these hydrocarbons allow an assessment of contamination patterns in marine and freshwater ecosystems. To perform such an assessment for the Fraser River basin, hydrocarbon data collected by federal and municipal sampling programs over the last decade from the Fraser River, six lakes within the Fraser basin and marine sediments from the Strait of Georgia have been synthesised. The resulting large, complex data set includes samples of surface sediment, suspended particulate matter and dated sediment cores. These samples have been analysed for a large suite of compounds in the hydrocarbon family including parent (unsubstituted) polycyclic aromatic hydrocarbons (PAHs), alkyl-substituted PAHs, alkanes, terpanes, hopanes and steranes.
