A U.S. Food and Drug Administration survey of lead and cadmium in 10 adult canned foods commonly eaten by children less than 5 years old was conducted between October 1981 and September 1985. The survey, which included foods preserved by a commercial canning process and packaged in metal containers, found the highest mean levels of lead (0.32 micrograms/g) in tuna and of cadmium (0.02 micrograms/g) in tuna and tomatoes. Lead levels in foods packaged in lead-soldered cans were about 5 times as high as those in foods packaged in nonlead-soldered cans. Mean lead levels appeared to decline over the 4 years of the study. Cadmium levels were usually below the data reporting limit (0.01 micrograms/g).
1981年10月至1985年9月期间,美国食品药品监督管理局对5岁以下儿童常吃的10种成人罐装食品中的铅和镉进行了调查。该调查涵盖了通过商业罐装工艺保存并包装在金属容器中的食品,发现金枪鱼中的铅平均含量最高(0.32微克/克),金枪鱼和西红柿中的镉平均含量最高(0.02微克/克)。用铅焊接罐包装的食品中的铅含量大约是非铅焊接罐包装食品中铅含量的5倍。在这项研究的4年期间,铅的平均含量似乎有所下降。镉含量通常低于数据报告限值(0.01微克/克)。
