e) Biota Samples Analytical precision for biological samples containing low concentrations of organochlorines was determined by triplicate analysis of a homogenised Ice Island plankton sample. Also, several replicates of seal blubber and Arctic char liver homogenates were analysed as part of an interlab calibration with two government labs to determine accuracy and precision at higher concentrations. A larger plankton sample ( 73pm net haul, c500pm size class, sample i.d. 1-Jar-86-119), collected in May 1986 was homogenised and triplicate samples (0.47-0.54g, dry weight) taken for organochlorine residue analysis. The results are given in Table 3.11. The mean relative standard deviation for the 18 quantifiable compounds in this homogenate was 17%. Arctic Labs has recently partipated in an interlab calibration with Canadian Wildlife Service (C.W.S.), Hull, Quebec (Henry Won and Richard Turle) and Department of Fisheries and Oceans (D.F.O.) at the Fresh Water Institute, Winnipeg (Bert Grift and Denis Muir) as part of a project monitoring chlorinated hydrocarbons in arctic biota samples (Thomas and ~amilton,l988)= The analytical methods used for the intercalibration were the same as for the 1987 Ice Island biota analyses and the results are useful for Ice Island method evaluation. Homogenates of ringed seal blubber and arctic char liver from Iqaluit and Pangnirtung, N.W.T. were prepared and shipped to the participating laboratories. The results for compounds monitored in this project for triplicate samples analysed by D.F.O. and C.W.S.and by Arctic Labs on two occasions and is summarised in Tables 3.12.(a) and 3.12.(b). PCBS were determined on the basis of individual congeners and consequently concentrations of PCBs as Aroclor 1254 were not reported, The Arctic Labs results are in good agreement with and comparable to the other particating labs. No significant systematic error is evident and the results appear to be of acceptable quality.
