This study investigated the presence of total mercury and organic mercury levels in various Carnivorous fish species captured from river. The results of mercury analysis in various specimens indicated that the some fish muscles tend to accumulate high levels of Hg and approximately 50-84% of that Hg is organic mercury. A. bengalensis bengalensis and W. attu possessed highest amount of organic mercury in their muscle tissues and contamination in M. armatus (0.45 ± 0.46), C. chitala (0.25 ± 0.18), R. rita (0.34 ± 0.15), L. calcarijer (0.25 ± 0.02) and O. pabda (0.26 ± 0.04) were also above the 0.25 µg Hg/g of wet weight, the limit set by PFA with the maximum level for consumption of fish exposed to MeHg. Though in P. pangasius (0.12 ± 0.16), B. bagarius (0.12 ± 0.01) and C. garua (0.1 ± 0.01), concentration was below the recommended level but in M. aor (0.23 ± 0.1) it was threatening. Interestingly, a low concentration of Hg was found in post-monsoon samples of all the species. Article in Journal/Newspaper Attu Zenodo |
