• Nutrients (such as amm<strong>on</strong>ia and phosphorus; Birkbeck et al. 1990);• Major i<strong>on</strong>s (such as sulphides and sulphates; Birkbeck et al. 1990; Soto et al.1991);• Metals (Birkbeck et al. 1990);• Phenolic compounds (such as phenol; Sellers 1977);• Resin acids (abietic acid, neoabietic acid, dehydroabietic acid, palustric acid,levopimaric acid, pimaric acid, and isopimaric acid; Samis et al. 1999);• Fatty acids (such as palmitic acid, stearic acid, lignoceric acid, oleic acid,linoleic acid, and linolenic acid; Samis et al. 1999);• Other chemicals (such as formaldehyde; Sellers 1977); and,• Natural plant horm<strong>on</strong>es (Johannessen and Ross 2002).3.1.1.3 Wood Preservati<strong>on</strong> FacilitiesThere are at least 15 operating wood preservati<strong>on</strong> facilities located within the <strong>Fraser</strong> <strong>River</strong>Basin. Five <str<strong>on</strong>g>of</str<strong>on</strong>g> these facilities are located within the Lower <strong>Fraser</strong> <strong>River</strong> Area <str<strong>on</strong>g>of</str<strong>on</strong>g> Interest,four are located within the Upper <strong>Fraser</strong> <strong>River</strong> Area <str<strong>on</strong>g>of</str<strong>on</strong>g> Interest, three are located withinthe South Thomps<strong>on</strong> <strong>River</strong> Area <str<strong>on</strong>g>of</str<strong>on</strong>g> Interest, two are located within the Lower Thomps<strong>on</strong><strong>River</strong> Area <str<strong>on</strong>g>of</str<strong>on</strong>g> Interest, and <strong>on</strong>e is located within the Nechako <strong>River</strong> Area <str<strong>on</strong>g>of</str<strong>on</strong>g> Interest. Thelocati<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> these facilities are shown in Figure 3.3 and the facility names and principalproducts produced are presented in Table 3.4.Freshly-cut s<str<strong>on</strong>g>of</str<strong>on</strong>g>twood lumber is susceptible to attack by moulds and fungi that candiscolour the wood or promote decompositi<strong>on</strong>. For this reas<strong>on</strong>, lumber and other forestproducts (e.g., poles) are frequently treated with various chemicals prior to transport andsale. Such wood preservati<strong>on</strong> and anti-sapstain chemicals include a variety <str<strong>on</strong>g>of</str<strong>on</strong>g> productsthat c<strong>on</strong>tain <strong>on</strong>e or more <str<strong>on</strong>g>of</str<strong>on</strong>g> the following active ingredients: creosote (and associatedPAHs); chromated copper arsenate (CCA); pentachlorophenol (PCP; which may c<strong>on</strong>tainPCDFs); amm<strong>on</strong>iacal copper arsenate (ACA); amm<strong>on</strong>iacal copper zinc arsenate (ACZA);chlorophenol; 2-(thiocyanomethylthio) benzothiazole (TCMTB); copper-8-quinolinolate(Cu-8); 3-iodo-2-propynyl butyl carbamate (IPBC); didecyldimethyl amm<strong>on</strong>ium chloride(DDAC); sodium carb<strong>on</strong>ate; borate (disodium octaborate tetrahydrate and disodiumtetraborate decahydrate); and/or, azac<strong>on</strong>azole (Johannessen and Ross 2002). Thequantities <str<strong>on</strong>g>of</str<strong>on</strong>g> these chemicals that are used in British Columbia each year (primarily in the<strong>Fraser</strong> <strong>River</strong> Basin) ranges from 0.0 kg for ACA (i.e., use was halted in 1999) to5,390,000 kg for creosote, based <strong>on</strong> the 1999 Survey <str<strong>on</strong>g>of</str<strong>on</strong>g> Pesticide Use in British Columbia17
