近年来,我国多地发生严重雾霾天气,空气动力学直径在2.5μm以下的颗粒物(PM2.5)被认为是大气污染的罪魁祸首。但粒径更小颗粒物的健康危害如何,目前尚无定论。近日,复旦大学公共卫生学院、上海市大气颗粒物污染防治重点实验室阚海东教授课题组的研究结果显示,粒径<0.5μm的大气颗粒物对人体健康危害更大,且粒径越小,危
In recent years, severe haze weather occurred in many places in our country. Particles (PM2.5) with aerodynamic diameter below 2.5μm were considered as the chief culprit of air pollution. However, the health effects of smaller particle size are still unknown. Recently, Fudan University School of Public Health, Shanghai Key Laboratory of Atmospheric Particle Pollution Control Professor Kan Haidong research group’s research results show that the particle size of <0.5μm atmospheric particles more harmful to human health, and the smaller the particle size, the risk
