最近从各方面证实,微量的铅会对人体产生严重的影响。有人认为其主要污染源来自含铅的汽油造成的大气污染,也有人认为来自食品中的微量铅。美国加里福尼亚工科大学Patterson教授在对格陵兰的冰雪成分分析中搞清楚铅污染大气的历史,从后者的角度向人们发出警告:“至少可以说,食品罐头中銲药(铅锡合金)里的铅是美国最严重的人体污染源。”那么为什么至今对这一个问题还没有引起人们的普遍注意呢?他认为,这是由于铅的微量分析
Recently confirmed from all aspects, trace lead will have a serious impact on the human body. Some people think that the main source of pollution comes from air pollution caused by leaded petrol, while others think it comes from trace amounts of lead in food.
