PM_(2.5)对人体健康影响的研究进展

Research progress on the effect of PM_(2.5) on human health

随着我国经济的飞速发展、城市建设以及工业规模的不断扩大,区域性环境污染问题日益突出。近年我国多个城市出现以细颗粒物为特征污染物的雾霾天气,对公众健康造成了较大的威胁,目前细颗粒物对空气质量的污染问题已经受到国内外专家的广泛关注。世界卫生组织发布的报告表明,由室外空气污染导致的过早死亡人数,平均为每天1000人,每年有35~40万的人面临着死亡。PM_(2.5)在细颗粒物中的比重较大,可达2/3,故笔者通过本文对近年来国内外文献对PM_(2.5)的组分、来源以及对人体健康的影响进行归纳总结,为更好地找出防护PM_(2.5)的措施提供依据。

With the rapid development of Chinese economy,urban construction and the continuous expansion of industrial scale,the regional environmental pollution problem has become increasingly prominent. In recent years,many cities in China appear pollutants haze weather with fine particles as the characteristics,causing a huge public health threat,the current particulate matter on the air quality of pollution has been the concern of domestic and foreign experts. The WHO report shows that the average number of premature deaths caused by outdoor air pollution is 1000 per day,350 to 400 thousand people each year in the face of death. PM2.5 in the proportion of fine particles is larger,up to 2/3. Domestic and foreign literature in recent years on PM2.5 components,sources and the impact of human health summarized in this article,so as to provide a basis for better finding out the protective measures of PM2.5.
