Analysis for suspension time of airborne particles due to Diwali fireworks in an urban atmosphere Lucknow
The study analyzed the additional load and suspension time of particle pollutants emerging from Diwali firecracker combustion between two different urban landscape sites in Lucknow, India. PM# (1, 2.5, and 10) and PSD (range: 0.2 μm to 20 μm), and chemical speciation of 15-elements and 6-ions of PM2.5 were assessed for Diwali and non-Diwali-days. In the commercial site, pre-Diwali-days to Diwali-day and pre-Diwali-days to post-Diwali-days added an extra load of PM# in the atmosphere by 3 to 5 times and 1.5 to 2 times respectively. Whereas, in the residential site, 2 to 3 times and 1 to 1.5 times increased PM# was observed. Variations in PM# suspension time due to Diwali fireworks were found as ~10 days at residential site and ~6 days at commercial site due to dissimilarities in the local source mix. Further, unimodal and bimodal PSD distributions and nearness observed between PSDs in two of the study sites revealed the influence of relative sources during Diwali and non-Diwali-days. Chemical markers of Diwali fireworks were identified as abundant in PM2.5 during Diwali and post-Diwali-days, but less in pre-Diwali-days. A strong correlation between markers of Diwali fireworks and their occurrence with PCA groups further confirmed the suspension period of PM# even during post-Diwali-days.
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
