作者首先指出研究含汞食物中毒的病因学时可注意两个途径:1.含汞工业污水污染的水体中的鱼;2.接触含汞农药的农产品。由于鱼体内甲基汞含量比例高(占80～100%),鱼体汞量甚至在“未污染”地区也比所有其他动植物性食物含量高,无机汞在水体和鱼体内可转变为甲基汞,第一条途径为主要危险。有 The authors first point out that there are two ways to look into the etiology of mercury-containing food poisoning: 1. fish in water contaminated with mercury-containing industrial wastewater; 2. agricultural products exposed to mercury-containing pesticides. As the proportion of methylmercury in fish is high (80-100%), the amount of mercury in fish is higher than that of all other animals and plants even in “uncontaminated” areas. Inorganic mercury can be converted to water in both water and fish Mercury, the first route is the main danger. Have
