Study of seasonal variation of PM2.5 concentration associated with meteorological parameters at residential sites in Delhi, India
The seasonal variation of particulate matter and its relationship with meteorological parameters were measured at five different residential sites in Delhi. Sampling was carried out for one year including all three seasons (summer, monsoon, and winter). The yearly average concentration of particulate matter (PM2.5) was 135.16 ± 41.34 µg/m3. The highest average values were observed in winter (208.44 ± 43.67 µg/m3) and the lowest during monsoon season (80.29 ± 39.47 µg/m3). The annual average concentration of PM2.5 was found to be the highest at the Mukherjee Nagar site (242.16 µg/m3 ) during the winter and lowest at (Jawaharlal Nehru University) JNU (35.65 µg/m3) during the monsoon season. The strongest correlation between PM mass and a meteorological parameter was a strong negative correlation with temperature (R2=0.55). All other parameters were weakly correlated (R2<0.2) with PM mass.
期刊介绍：
The Journal of Atmospheric Chemistry is devoted to the study of the chemistry of the Earth''s atmosphere, the emphasis being laid on the region below about 100 km. The strongly interdisciplinary nature of atmospheric chemistry means that it embraces a great variety of sciences, but the journal concentrates on the following topics:
Observational, interpretative and modelling studies of the composition of air and precipitation and the physiochemical processes in the Earth''s atmosphere, excluding air pollution problems of local importance only.
The role of the atmosphere in biogeochemical cycles; the chemical interaction of the oceans, land surface and biosphere with the atmosphere.
Laboratory studies of the mechanics in homogeneous and heterogeneous transformation processes in the atmosphere.
Descriptions of major advances in instrumentation developed for the measurement of atmospheric composition and chemical properties.
