4. RESULTS Results are presented in the following sections for each type of sample collected. Quantifiable concentrations of organochlorines were found in all types of samples with the exception of particulates from ice melt and sea water as a result of the very low quantities of particulates in these samples. Detailed data for all compounds monitored are given in ~ppendices A - F. 4.1 Air 4.1.1 Va~our Phase A summary of quantifiable or detectable organochlorines in the vapour phase for all three sampling trips is given in Table 4.1 and detailed in Appendix A. The alpha and gamma isomers of HCH and HCB were the most abundant compounds. Total HCH concentrations were between 250 - 500 pg/m3. HCB concentrations were 70 - 100 pg/m3 while all other compounds were at concentrations of less than 10 pg/m3. Seasonally, concentrations of alpha HCH, cis and trans chlordane and DDE were lowest in August/September. Concentrations of other compounds did not display any significant seasonal'variation. Ratios of alpha and gamma HCH and trans and cis chlordane were variable. Concentrations of gamma HCH (lindane) were significantly lower in August/September. As a result, mean a1pha:gamma ratios were increased to 16 from a value of 6 in May and 3.5 in June. The ratio of trans:cis chlordane was 0.5 in June 1987, the only data set where concentrations of trans and cis chlordane were quantifiable in all samples. Data collected in August gave ratios of less than 1 but trans chlordane levels were all below detection. In May 1986, for the few samples with quantifiable levels, trans chlordane concentrations were the same as in June but the concentration of the cis isomer was 3 times lower giving a trans:cis ratio of 1.5.
