) In-situ Particulate Sampling Replicate samples were taken with the in-situ samplers on all sampling trips at three depths to determine sampling and analytical precision. The filters were uniformly very low, which is consistent with the low SPM and POC values found (Table 4.4), and few organochlorine values were above the detection limits, although samples were run at the highest sensitivity with clean and consistent procedural blanks. Consequently, precision for the compounds not detected could not be determined, but were consistently below the detection limits. The detection limits for 1986 and 1987 filter samples based on several filter procedural blanks from each suite are listed in Table 3.4 in picograms per filter and picograms/litre for typical sample volumes. The most abundant compounds found, HCB, a-HCH and trans- chlordane, were present at concentrations close to the limits of detection or quantitation, and consequently are of low precision. Typical ISS filter replicates are presented in Table 3.5. Replicate samples with the in-situ sampler were taken on all sampling trips at various depths (Appendix C). These samples give a measure of the sum of the analytical, sampling and natural water variability as samples were taken over a period of several days. Natural water variability over the whole water column is assumed to be slight in the time period of a few days or weeks. Analyses for all compounds were least variable in June 1987. Results for the first and second trips were similar and more variable than the June data. For a-HCH, at concentrations of >4000 pg/L, a relative standard deviation of 12 - 15% was obtained in May and August samples; 6% in June. At concentrations of less than 500 pg/L corresponding values were 41% in May and 7% in June. For gamma-HCH, variability was less; typically better than 10% at concentrations of about 500 pg/L and 15 - 30% a% concentrations less than 100 pg/L. Precision of replicates for the less abundant compounds was generally k50% and as much as
