编辑同志: 我从有关报刊中看到,儿童医学专家近期对江、浙、沪学前儿童血铅水平进行了抽样调查,发现血铅水平的平均值为9.78微克/分升,这个数据远远高于目前美国儿童3.6微克/分升的平均值。据悉,每分升血液中铅含量超过10微克时,便会对儿童脑发育产生不良影响,特别是会损害儿童的神经和智力。我想听专家谈谈与儿童有关的铅污染问题。 一位热心的读者
Editor’s Comrade: I read from the newspapers that pediatric medical experts recently conducted a sample survey of blood lead levels in pre-school children in Jiangsu, Zhejiang and Shanghai and found that the average blood lead level was 9.78 μg / dl, a figure far higher The current average of 3.6 μg / dL for U.S. children. It is reported that per liter of blood lead content of more than 10 micrograms, it will have a negative impact on children’s brain development, especially in children will damage the nerves and intelligence. I would like to hear an expert talk about children-related lead pollution. An enthusiastic reader
