一项研究发现,与欧洲和北美的PM2.5相比,中国的PM2.5致命性要低得多。中国疾病预防控制中心专家周脉耕领导的这个研究团队提出,这是因为中国的空气污染源于从干旱地区吹来的大量天然尘土,而西方的污染主要来自工业。
Smog in Europe and North America could be more than 25 times more lethal than the average air pollution found in Chinese cities, a new study suggests.
一项最新研究发现,欧洲和北美的雾霾致命性可能比中国城市平均空气污染水平高出25倍以上。
In the largest ever study of its kind in the developing world, researchers tested the effects of air pollution on the health of people in 272 cities in China.
在这项有史以来针对发展中国家进行的最大规模的同类研究中,研究人员测试了中国272个城市里空气污染对人体健康的影响。
They found average annual exposure to fine particles, known as PM2.5, in those cities was more than five times higher than the level recommended by the World Health Organisation (WHO), according to a paper in the American Journal of Respiratory and Critical Care Medicine.
研究人员发现,在这些城市中,人们的年均PM2.5接触量是世界卫生组织建议水平的5倍多。研究论文发表在《美国呼吸系统和重症护理医学杂志》上。
However they also discovered that it was much less likely to increase the death rate than PM2.5 in Europe and North America.
