| organic and total mercury levels in bigeye tuna, thunnus obesus, harvested by taiwanese fishing vessels in the atlantic and indian oceans. | muscle samples of 121 and 110 bigeye tuna (thunnus obesus) caught by taiwanese long-line fishing vessels in the atlantic and indian oceans, respectively, were used to analyze total mercury (thg) and organic mercury (ohg) content. the overall thg and ohg concentrations were 0.786 ± 0.386 (0.214-3.133) and 0.595 ± 0.238 (0.143-2.222) mg kg⁻¹ wet weight, respectively, similar to the results of previous studies. our findings, however, reflected the highest thg and ohg concentrations for the species ... | 2011 | 24779657 |
