Effect of sample preservation on body burden analysis of organic contaminants in unionid mussels / M. Hanna.: En13-5/90-34E-PDF
"In order to quantitatively assess the effect of the temporary thawing out of the St. Lawrence mussel samples, collected between Lake St. Louis and Tadoussac, a comparative analysis was carried out on the unionid mussel Elliptio complanata, resampled by Ponar dredge from one site in the Cornwall/Massena area. To adequately reproduce the conditions of the thawing out problem, the mussels were divided into two groups, while Group A was kept in the freezer at -20°C, Group B was kept in the refrigerator for five days at 5°C. All the compounds present in the control were also present in Group B samples. Analysis of the organic contaminants in each of these two groups showed that for total PCB concentrations, the two treatments were not significantly different; however, when compared individually 6 of the 13 congeners showed significant differences. The observed differences were relatively small for individual PCB congeners (7.1 to 15.3%), higher for chlorobenzenes (10.5 to 36.4%), and yet higher for HCE (44.1%); the difference for HCE, although large is nevertheless not significant, even if only marginally so"--Abstract.
