This includes increased monitoring of particulate matter in the air.
这其中包括对空气中颗粒物监测的增加。
The country now only reports air quality based on readings of PM10, particulate matter smaller than 10 microns, which is why monitoring results do not match people's sense of pollution.
现在，国家只报告基于空气污染指数PM 10，及颗粒物小于10微米，这就是为什么监测结果不能匹配人们对空气污染的认识。
Environmental air quality standards were revised. The air quality index for monitoring fine particulate matter (PM2 s) was added.
修订环境空气质量标准，增加细颗粒物PM 2.5等监测指标。
