摘要: Levels of mercury, methylmercuri and selenium were determined in liver samples from wild mink (Mustela vision) caught the Norwegian countries Rogaland (38 samples), Sogn og Fjordane (15 samples) Hedmark (18 samples). The average mercury levels these counties 2.6, 3.1 2.1 micrograms Hg/g wet weight, respectively. No significant differences found. methyl (MeHg) 30 samples. A very strong positive correlation between total (Hg) (r = 0.91, P less than 0.001) was level 35 per cent mercury. This indicates that has ability to demethylate 0.87, There no age or nutritional condition level. In present study examined see it could be recommended as an indicator species for monitoring local environment contamination. definite answer this question did reveal, however, all studied there are individuals considerably contaminated with
