 | | The chromatographic pattern of ΣCHBs in the Hanson Lake sediment is dominated by 2-exo, 3-endo,6-exo,8,9,10- hexachlorobornane (Hx-Sed or B6-923) and 2-endo, 3-exo,5-endo,6-exo,8,9,10-heptachlorobornane (Hp-Sed or B7-1001) (Stern et al., 1995; Andrews et al., 1995). |
 | | In the Watson and Fox Lake sediments, Hx- and Hp-Sed are the predominant CHB congeners in both cases suggesting contamination by a non-atmospheric source. |
 | | In Lake Laberge, Hx- and Hp-Sed are much more prevalent in the core slices representing the years 1972-1976 compared to the period of 1980 to 1991 but, do not predominate nearly to the same extent as observed in the sediments from Hanson, Fox, or Watson Lakes. |
