一提到霾,你也许想到霾的“元凶”——PM2.5,但科学家最新研究显示,比PM2.5更加小的颗粒物——PM0.5,对人体的危害也许更大。而且,由于PM0.5非常微小,论质量,它微乎其微;但如果论数量,在被污染的空气中,它们的颗粒数占了将近90%。看来,这PM0.5也不容忽视,甚至可能是霾的新“元凶”呢。对PM0.5危害的研究最近,复旦大学公共卫生学院的课题组发现,PM0.5以下的颗粒物会沉积在肺泡深处,进入血液,对呼吸系统和心血管造成伤害。相比较
When it comes to haze, you may think of haze as “culprit” - PM2.5, but new research by scientists shows that PM0.5, which is even smaller than PM2.5, may be even more harmful to humans. Moreover, since PM0.5 is very small, it is minimal in terms of quality, but in the case of quantity, the number of particles in polluted air accounts for nearly 90%. It seems that this PM0.5 can not be ignored, and may even be the new “culprit” of haze. Research on the hazards of PM0.5 Recently, the research group of the School of Public Health of Fudan University found that particles below PM0.5 could deposit in the alveoli and enter the bloodstream, causing damage to the respiratory system and cardiovascular system.
