Title

Contamination levels and human health risk assessment of mercury in some fish species from the Anzali International Wetland, Iran

Pages

  205-220

Abstract

 2Background and Objective: The presence of toxic mercury in Fish has caused global concern, as one of the main ways of humans are exposed to it is through Fish consumption. Therefore, the main goal on this research was to determine the concentration of mercury in Fish and evaluate the health risk to consumers. Materials and Methods: Samples of pike, common perch, European perch, common carp and goldfish were collected from Anzali Wetland. Mercury concentration was measured using a graphite furnace atomic absorption spectrometer. Differences in mercury concentration among the species and the comparison of mercury concentration with the standards were analyzed using one-way analysis of variance and one sample t-test, respectively. Results: The average concentrations of mercury for pike, common perch, European perch, common carp and goldfish were 59. 59, 67. 55, 30. 45, 9. 84, and 10. 44 µg/kg ww, respectively. The results showed significant differences in mercury concentrations among different species. The concentrations of mercury in all samples were below the permissible limits of international standards (300 and 500 µg/kg dw), and the HQ index values were less than 1. Therefore, the results indicated no potential risk to consumer health. Additionally, the consumption of European perch, common carp and goldfish is considered safe for sensitive people (children and pregnant women). Conclusion: In general, there was no potential concern regarding mercury exposure from consuming the studied Fish species
