AbstractThe characteristics of fine particulate pollution (PM10and PM2.5) were measured at urban and suburban sites in Jinan during the 2008–2009 heating and non-heating seasons. The results showed that PM10and PM2.5pollution was quite serious, and PM mass concentration was higher during the heating season than the non-heating season. PM was the highest in the chemical factory and lowest in the development zone. The mass concentrations of PM10and PM2.5were linearly related, and the mass concentration ratio of PM2.5/PM10was up to 0.59 in urban areas. PM pollution in Jinan was related to local meteorological factors: PM2.5mass concentration and humidity were positively correlated, and PM2.5mass concentration was negatively correlated with both click on the temperature and wind speed, although wind speed varied more.
