[Method] Research progress in risk assessment of methylmercury intake from fish and shellfish is introduced in the study. [Result] Aquatic products are part of a healthy diet for human. However, almost all fsh and shellfish contain at least a trace amount of methylmercury. The methylmercury content in wild fsh is higher than that of cultured fsh. The methylmercury content in different aquatic products is in the order： carnivorous fsh 〉 omnivorous fsh 〉 flter-feeding fsh 〉 benthic organisms 〉 herbivorous fsh 〉 phytoplankton 〉 zooplankton, and the methylmercury content in different organs is in the order： back muscles 〉 belly muscles 〉 liver 〉 heart 〉 other organs and tissues. [Conclusion] The harm of methylmercury in fsh and shellfsh is of low risk and would not cause harm to health. However, women of childbearing age, pregnant woman, nursing woman and children should eat fsh with low mercury content and avoid some large-fsh intake.展开更多
