摘要
汽油无铅化后,我国儿童铅中毒问题仍相当严重,群体铅中毒事件频频发生,铅中毒流行率相对较高且有回升趋势,膳食铅摄入量过高。在各类铅污染源中,燃煤铅排放已成为大气铅污染的重要贡献者,初步估算表明,2001—2005年燃煤大气铅排放总量达4.5万t,铅排放量与铅中毒率之间呈显著相关关系。预防铅中毒应切实加强环境污染的有效控制和敏感人群的定期监测,铅中毒监测亦应采取血铅测定和发铅测定双管齐下的方针。
After applying lead - free gasoline, children lead poisoning problem is still very serious, groups with frequent incidents of lead poisoning, the relatively high prevalence of lead poisoning and there is rising trend, high dietary intake of lead. In various lead pollution, lead emissions from coal - fired atmospheric lead pollution has become an important contributor. Preliminary estimates indicate that from 2001 to 2005 the total coal - fired atmospheric lead emissions 4.5 million tons, the relation between the rate of emissions and lead poisoning was a significant correlative. The prevention of lead poisoning should strengthen the effective control of environmental pollution and sensitive populations of regular monitoring, lead poisoning should also be taken to monitor blood lead measurement and determination of hair lead a two -pronged approach.
