数据库：城市室外空气污染
The database contains results of urban outdoor air pollution monitoring from almost 1100 cities in 91 countries. Air quality is represented by annual mean concentration of fine particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 microns).
这个数据库包含91个国家，几乎覆盖1100个城市的城市室外空气污染检测结果。空气质量用年平均细颗粒物的浓度表示（PM10至PM2.5,即粒径小于等于10或2.5微米的细颗粒）。
The database covers the period from 2003 to 2010, with the majority of values for the years 2008 and 2009. The primary sources of data include publicly available national/subnational reports and web sites, regional networks such as the Asian Clean Air Initiative and the European Airbase, and selected publications. The database aims to be representative for human exposure, and therefore primarily captures measurements from monitoring stations located in urban background, urban traffic, residential, commercial and mixed areas.
该数据库涵盖2003年至2010年，大多数为2008年和2009年的数值。数据的主要来源包括公开可用的国家/分管机构的报告和网站，诸如“亚洲清洁空气行动”和“欧洲空军基地”等区域性网络以及挑选的出版物。该数据库旨在代表人体感染程度，因此，主要捕获来自城市背景的监控站，城市交通，住宅区，商业区以及混合区的测量值。
The world's average PM10 levels by region range from 21 to 142 ug/m3, with a world's average of 71 ug/m3.
各区域平均PM10(粒径范围为10微米的细微粒)水平范围为21~142ug/m3,世界平均水平为71ug/m3.
Afr: Sub-Saharan Africa; Amr: Americas; Emr: Eastern Mediterranean; Eur: Europe; Sear: South-East Asia; Wpr: Western Pacific; HI: High income; LMI: Low and middle income; PM10: Fine particulate matter of 10 microns or less.
