当被问及在研究美国以及世界其他地方的铅中毒的生涯中,最令他们惊讶的是什么时,参加美国科学促进会年会的专家们异口同声地回答道:人们错误地以为我们已经摆脱了铅毒,这一点最令人吃惊。尽管美国致力于降低儿童的血铅含量,在消除含铅汽油和限制铅颜料方面取得了很大的成功,但是铅污染在国际上仍然是一个需迫切解决的问题。 When asked what surprised them most during their study of lead poisoning in the United States and elsewhere in the world, experts participating in the annual meeting of the American Association for the Advancement of Science replied in the same breath: People mistakenly thought that we had gotten rid of Lead poisoning, this is the most surprising. Although the United States is committed to reducing blood lead levels in children and has achieved great success in eliminating leaded gasoline and limiting lead pigments, lead pollution remains a pressing issue in the world.
