ABSTRACT: In recent years, the haze occurs frequently
and air pollution is getting worse in Beijing-Tianjin-Hebei Region, China. The
particulate matter pollution characteristic researches are playing a
sig-nificant role especially in the districts where have higher concentration
PM and air pollution. In this study, we collected daily particulate matter
(PM10, PM2.5) mass concentration data from 7 air pollution monitoring stations
in Shijiazhuang City, Hebei, China over a 3-month period from June to August to
investigate particulate matter pollution characteristic and the relationship
with me-teorological conditions. Statistical results show that PM10 is the major
pollutant in Shijiazhuang City; the average daily concentrations of PM2.5 and
PM10 are 94.45 μg/m3 and 219.15 μg/m3, respectively. The daily average of PM10
and PM2.5 level over the period exceeded the first grade of the daily average
limit of the ambient air quality standards (GB3095-2012). And there is a
significantly positive correlation between atmospheric pressure and particulate
matter pollution, but there is a significantly negative correlation between
atmospheric temperature and PM concentrations. Precipitation has a clear role
mainly in the coarse particles; however, there has little effect on fine
particulate matter. Relative humidity and wind speed have a poor correlation
with atmospheric pollutant concentrations (not remarkably high).
