A masked cyclist rides her electric bike on a road in heavy fog in Jinan city, east Chinas Shandong province, 6 December 2011. A government proposal for a tighter system of monitoring pollution nationwide, including using a PM2.5 measure of microscopic airborne particles, has won support from a majority of the public, the Ministry of Environmental Protection said Wednesday (7 December 2011). The new standard would require air-quality watchdogs to monitor airborne particles, those measuring less than 2.5 microns in diameter, and publish the findings.

据路透社报道,北京大学和绿色和平共同进行的一项研究显示,四座中国大城市的微型空气污染颗粒今年已经造成大约8600人过早死亡,以及大约10亿美元的经济损失。这项研究主要针对北京、上海、广州和西安四座大型城市的PM2.5空气污染指数,反映直径小于或等于2.5微米的颗粒物在空气中的存在,这种污染物可以直接吸入肺部,对呼吸系统和整个身体健康具有严重的危害。研究结果显示,如果能够达到世界卫生组织设定的空气质量准则,那么上述城市因PM2.5污染颗粒造成的早死人数将会减少八成以上。
