• Surfactants (i.e., APEOs, such as octylphenols and nonylphenols);• Fire retardants [e.g., tri(2-chloroethyl)phosphate];• Antioxidants (e.g., 2,6-di-tert-butylphenol);• Other chemicals (e.g., phenols, bisphenol A, and triclosan);4. Sex and storoidal hormones, including:• Biogenics (e.g., estriol, estrone, progesterone);• Pharmaceuticals (e.g., 17á-ethynylestradiol, mestranol); and,• Sterols (e.g., cholesterol, stigmastanol).In addition to these substances, it is likely that the following chemicals also representcontaminants <strong>of</strong> emerging concern in the Fraser River Basin:• Organometallic substances (TBT);• In-use herbicides (ethalfluralin, pendimethalin);• In-use fungicides (dazomet, mancozeb, metam, metiram);• Wood preservatives (CCA, ACZA);• Anti-sapstain chemicals (DDAC, IPBC);• Additional fire retardants, including PBDEs and PBBs;• Fluorosurfactants, including PFOS, PFOA;• Polychlorinated paraffins; and,• Nanoparticles.These latter substances should be identified as contaminants <strong>of</strong> emerging concern becausethey are being used or are likely being used in the study area, they have been measured inenvironmental media at elevated or increasing levels, environmental quality guidelines forwater, sediment, and/or fish tissues are not available in Canada, and/or incompleteinformation is available on their toxicity to fish and other aquatic organisms.6.2.2 Sources and Releases <strong>of</strong> <strong>Contaminants</strong> <strong>of</strong> Emerging Concern in theFraser River BasinThere are numerous sources <strong>of</strong> contaminants <strong>of</strong> emerging concern in the Fraser RiverBasin. For the pharmaceuticals and personal care products, natural hormones andnanoparticles, municipal wastewater treatment plants represent the primary sources <strong>of</strong>107
these substances to aquatic ecosystems. However, run-<strong>of</strong>f from biosolids application sites,feedlots, and/or manure application sites represents a potential source <strong>of</strong> these chemicals.Various fire retardants and surfactants can also be released from municipal and industrialwastewater treatment plants. Discharges and run<strong>of</strong>f from industrial and manufacturingfacilities also represent sources <strong>of</strong> plasticizers, industrial chemicals, fire retardants, andsurfactants. Wood preservation facilities represent the primary sources <strong>of</strong> woodpreservatives and anti-sapstain chemicals released to receiving waters. Tributyltin andother organotins are likely to be released to the environment from anti-fouling paintsapplied to ocean-going vessels. Atmospheric transport and deposition likely represents animportant source <strong>of</strong> certain contaminants <strong>of</strong> emerging concern, such as PBDEs and PBBs.Chapter 3 provides more information on the sources <strong>of</strong> these contaminants in the studyarea.6.2.3 <strong>Potential</strong> <strong>Effects</strong> <strong>of</strong> <strong>Contaminants</strong> <strong>of</strong> Emerging Concern on FishIncomplete information is available in the scientific literature to evaluate the nature <strong>of</strong>effects associated with exposure <strong>of</strong> fish to contaminants <strong>of</strong> emerging concern. However,the available data on the endocrine disruption effects <strong>of</strong> certain groups <strong>of</strong> thesecontaminants were discussed in Section 6.1.5 <strong>of</strong> this document. An evaluation <strong>of</strong> thetoxicity <strong>of</strong> the other contaminants <strong>of</strong> emerging concern in the Fraser River Basin was notconducted as part <strong>of</strong> this investigation.6.2.4 <strong>Potential</strong> Exposure <strong>of</strong> Sockeye Salmon to <strong>Contaminants</strong> <strong>of</strong> EmergingConcern in the Fraser River BasinFew data are available with which to document exposure <strong>of</strong> sockeye salmon tocontaminants <strong>of</strong> emerging concern within the Fraser River Basin. However, informationon the locations <strong>of</strong> likely sources can be used to infer the levels <strong>of</strong> exposure <strong>of</strong> various lifestages <strong>of</strong> sockeye salmon to these contaminants. This information suggests that exposureto contaminants <strong>of</strong> emerging concern associated with industrial or municipal wastewatertreatment plant discharges is likely to be negligible for sockeye salmon eggs and alevins inmost <strong>of</strong> the conservation units within the Fraser River Basin. However, all stocks <strong>of</strong>sockeye salmon are likely to be exposed to these contaminants for which atmospherictransport represents an important source. Similarly, it is assumed that exposure <strong>of</strong>sockeye salmon to contaminants <strong>of</strong> emerging concern originating from municipal orindustrial sources is negligible during early rearing for virtually all stocks in the study area.The exception could be the Harrison River stocks that rear in backwater areas and sloughswithin the Lower Fraser River for a period <strong>of</strong> time before migrating to Georgia Strait.108
