近10年来儿童血铅质量浓度在许多国家已经明显下降。世界卫生组织/疾病预防与控制中心(WHO/CDC)提出血铅质量浓度在10μg/dL(0·483μmol/L)以下为安全界限,目前许多发达国家平均水平为3μg/dL。但铅中毒仍然是当今全球范围内威胁儿童身心健康的主要公共卫生问题。铅暴露对儿童
Blood lead concentrations in children have dropped significantly in many countries over the past 10 years. The World Health Organization / Centers for Disease Control and Prevention (WHO / CDC) proposed that blood lead concentrations below the safety margin of 10μg / dL (0.483μmol / L), the current average level of many developed countries 3μg / dL. Lead poisoning, however, continues to be a major public health problem that threatens children’s physical and mental health worldwide today. Lead exposure to children
