Exposure to methylmercury (MeHg) from fish and marine mammal consumption continues to present a public health concern. To date, developmental neurotoxicity is the most sensitive health outcome, forming the basis for health-risk assessments and the derivation of biomonitoring guidance values. This article summarizes existing Health Canada MeHg blood guidance values for general population and expands them to include a harmonized provisional interim blood guidance value of 8 microg/L based on the existing provisional Tolerable Daily Intake for children, pregnant women and women of childbearing age. Associated public health actions, according to age, sex, and level of exposure are recommended.
食鱼和海洋哺乳动物会接触到甲基汞(MeHg),这仍然是一个公共卫生关注点。迄今为止,发育神经毒性是最敏感的健康结果,为健康风险评估和生物监测指导值的推导提供了基础。本文总结了加拿大卫生部现有的一般人群甲基汞血液指导值,并根据儿童、孕妇和育龄妇女暂定每日耐受摄入量,扩展至包括 8 微克/升的协调暂定临时血液指导值。根据年龄、性别和暴露水平,建议采取相关公共卫生行动。
