近年来的研究表明,即使血铅水平在10μg/L以下,也会影响儿童的神经发育,故目前美国国家疾病预防控制中心不再认为10μg/L为儿童血铅水平的安全阈值。由于胎儿神经系统易受外界因素的影响,因此孕期低水平铅暴露对儿童神经发育的损害逐步受到重视,本文就孕期低水平铅暴露与儿童发育行为学的关系进行综述。 In recent years, studies have shown that even if the blood lead levels below 10μg / L, will also affect children\'s neurological development, so now the U.S. National Center for Disease Control no longer think that 10μg / L for children blood lead level safety threshold. As the fetal nervous system is susceptible to external factors, the low level of lead exposure during pregnancy, children\'s neurodevelopment damage gradually attention, this article review low levels of lead exposure during pregnancy and child developmental behavior.
