Background. Mercury (Hg) is considered a toxic metal being present in various fish species. Assessing the variability of Hg concentrations in different fish species is a decisive element for the population's exposure assessment to Hg. Objective of the study. We assessed the Hg concentrations in different fish species most commonly traded in the Republic of Moldova and have compared them with the Hg concentrations extracted from the World Health Organization database - GEMS/Food contaminants. Material and Methods. Were collected 189 samples (n) during October 2017 according to ГОСТ 26927-86. From GEMS/Food contaminants were extracted 23025 analytical results, characteristic for the period 01.01.1972 - 31.12.2018. The data of the 17 fish species included were processed in IBM SPSS statistics 26, with the assessment of mean values (m), standard deviation (SD) and the MannWhitney U test was applied. Results. The highest average concentrations, with reference to the 189 samples collected, were estimated for pike (n=7) - 0.144mg/kg ± 0.031, sea perch (n=5) - 0.140mg/kg ± 0.011, tuna (n=10) - 0.109mg/kg ± 0.028. Based on GEMS/Food, the highest mean Hg concentrations were: shark (n=1698) - 0.828mg/kg ± 0.750, tuna (n=2945) - 0.305mg/kg ± 0.318 and sea perch (n=243) - 0.207mg/kg ± 0.330. Data are presented as m±SD. Applying the Mann-Whitney U test for the comparison of the averages of this 2 data sets, we estimated that for 8 out of 17 fish species there was no statistically significant difference (p>0.05), for 9 species there was a statistically significant difference (p<0.05). Conclusion. The results obtained suggest that for estimating Hg exposure through fish consumption using small data sets they are less likely to include variability in Hg concentrations compared to large data sets (GEMS/Food). |
