8821 什么铅中毒? What is lead poisoning?
8822 铅中毒系指过度接触铅。 Lead poisoning refers to excessive human exposure to lead.
8823 接触途径可包括吸入铅烟雾和颗粒(例如来自冶炼),或者摄入被铅污染的粉尘(例如来自腐朽的含铅涂料)、水(因含铅管道受污染)或食品(因铅釉或铅焊容器受污染)。 Exposure can occur from inhalation of lead fumes and particles (e.g., from smelting) or from ingestion of lead-contaminated dust (for example, from decaying lead paint), water (from leaded pipes) and food (from lead-glazed or lead-soldered containers).
8824 发生这种接触的时间可能较(急性中毒),也可能较长(慢性中毒)。 This exposure may occur over a short period (acute poisoning) or over a prolonged period (chronic poisoning).
8825 迄今尚未确定没有有害影响铅接触水平 No level of exposure to lead that is without harmful effects has so far been identified.
8826 因此,一些卫生部门确定,血铅浓度高于整体人口参照值,即为过度接触 As a consequence, some health authorities define excessive exposure as having a blood lead concentration above the reference value for the population as a whole.
8827 参考值通常是代表人口前2.5%或5%(即百分位第97.5位和95位)的血铅浓度 This reference value is usually the blood lead concentration that characterises the top 2.5% or 5% of the population, i.e., the 97.5th or 95th percentile, respectively.
8828 例如,美国根据2008年至2012年对6岁以下儿童观察到的第97.5百分位血铅浓度,于2012年确定的参考值为5µg/dL (2) 。 For example, in the USA, the Centre of Disease Control and Prevention lowered its blood lead reference value to 3.5 µg/dL for children ages 1-5 years in October 2021 (2) , in France, 5 µg/dL is the 98th percentile value for children under 7 years (3).
8829 法国7岁以下儿童的第98百分位值为5µg/dL (3) 。 WHO recommends that for an individual with a blood lead concentration  5 µg/dL, the source(s) of lead exposure should be identified and appropriate action taken to reduce and terminate exposure (4).
