在严格质量控制条件下 ,对湖北省的繁华城区 (武汉市 )、矿区 (大冶 )及乡村 (宜都 ) 3个不同空气污染地区非职业铅接触的 10 5名非孕妇女血铅和 96名孕妇血铅和乳铅含量进行了追踪调查。结果乡村非孕妇女的血铅水平低于城区和矿区 ,但城区乳铅水平及孕末期血铅水平低于矿区及乡村。对这种差别的影响因素进行了讨论。结论认为 ,乡村妇女铅暴露水平低于城市和工矿区 ,但不可忽视极低浓度的铅污染对孕妇存在的潜在危害。
Under strict quality control conditions, blood lead levels and blood lead levels of 105 non-pregnant women exposed to non-occupational lead in three prospective urban areas of Wuhan (Hubei Province), the mining area (Daye) and the rural areas (Yidu) Pregnant women lead and milk lead content were investigated. Results The level of blood lead in rural non-pregnant women was lower than that in urban areas and mining areas, but the level of lead in urban areas and the level of blood lead in the end of pregnancy were lower than those in mining areas and villages. The influencing factors of this difference are discussed. The conclusion is that the level of lead exposure of rural women is lower than that of cities and industrial and mining areas, but the potential harm to pregnant women caused by lead pollution of very low concentration can not be neglected.
