Squids are globally distributed. Hg-contaminated squids may have high risks on humans. With abundant Se (antagonistic effect on Hg), the risks can be reduced. We collected squids around the world (Northwest Pacific Ocean, Southeast Pacific Ocean and Indian Ocean). Concentrations of Hg and Se were region-based and tissue-based. The higher content of Se were, the lower relative Hg levels were. The correlation between Se:Hg and Se was the strongest in the digestive gland. The values of Se:Hg and THQ all confirm that the health risk was lower in samples with higher concentrations of Se. Despite the risk assessment by Se:Hg, BRV and THQ analysis showed no risk when consumed in moderation, the maximum daily intake is provided based on Monte Carlo simulation. In future, when evaluating the risks cause by Hg exposure and providing the recommended daily amount, it may need to concurrent consideration of Se levels.

鱿鱼分布于全球。受汞污染的鱿鱼可能对人类有很高的风险。含有丰富的硒（对汞有拮抗作用），可以降低风险。我们收集了世界各地（西北太平洋、东南太平洋和印度洋）的鱿鱼。汞和硒的浓度是基于区域和组织的。硒含量越高，相对汞含​​量越低。Se:Hg 和 Se 之间的相关性在消化腺中最强。Se:Hg 和 THQ 的值都证实，Se 浓度较高的样品的健康风险较低。尽管 Se:Hg 的风险评估、BRV 和 THQ 分析表明适量食用没有风险，但根据蒙特卡罗模拟提供了每日最大摄入量。在未来，
