“…The goal of PMF is to minimise this function. PM data from the different sizes (PM 2.5 and PM 10 ) were combined and inputted into PMF, as has been done in related works (Amato et al, 2009;Aldabe et al, 2011). The combined data showed satisfactory results, and further analysis demonstrated that the profiles of PM 2.5 and PM 10 were similar in this work.…”

Abstract. To quantify the total, direct and indirect impacts of fireworks individually, size-resolved PM samples were collected before, during and after a Chinese folk festival (Chinese New Year) in a megacity in China. Through chemical analysis and morphological characterisation, a strong influence of fireworks on the physicochemical characteristics of PM 10 and PM 2.5 was observed. The concentrations of many species exhibited an increasing trend during the heavy-firework period, especially for K + , Mg 2+ and Cr; the results of the non-sea-salt ions demonstrated an anthropogenic influence on K + and Mg 2+ . Then, source apportionment was conducted by receptor models and peak analysis (PA). The total influence of the fireworks was quantified by positive matrix factorisation (PMF), showing that the fireworks contributed higher fractions (23.40 % for PM 10 and 29.66 % for PM 2.5 ) during the heavy-firework period than during the light-firework period (4.28 % for PM 10 and 7.18 % for PM 2.5 ). The profiles of the total fireworks obtained by two independent methods (PMF and peak analysis) were consistent, with higher abundances of K + , Al, Si, Ca and organic carbon (OC). Finally, the individual contributions of the direct and indirect impacts of fireworks were quantified by chemical mass balance (CMB). The percentage contributions of resuspended dust, biomass combustion and direct fireworks were 36.8 ± 8.37 %, 14.1 ± 2.82 % and 44.4 ± 8.26 %, respectively, for PM 10 and 34.9 ± 4.19 %, 16.6 ± 3.05 % and 52.5 ± 9.69 %, respectively, for PM 2.5 , in terms of the total fireworks. The quantification of the total, direct and indirect impacts of fireworks in the ambient PM gives a original contribution for understanding the physicochemical characteristics and mechanisms of such high-intensity anthropogenic activities.

“…Adverse health and the environmental and climate effects of aerosol particles are derived from the chemical components and properties of those particles (Hueglin et al, 2005;Aldabe et al, 2011). Water-soluble ions are major components of atmospheric aerosols and can comprise up to 60-70% of particulate mass.…”

Ambient PM 2.5 was sampled in three indoor environments (a common office, a photocopy room and a student dormitory) and one outdoor environment (a rooftop) on a campus of Nanchang University in Nanchang city, China, on June 5-20, 2009. Analysis by ion chromatograph showed the indoor-outdoor differences and relationships of water-soluble ions. The indooroutdoor distributions indicated that chemicals and household garbage contributed most to the generation of water-soluble ions indoors. The indoor-outdoor relationships of water-soluble ions in PM 2.5 in the common office and student dormitory were unrelated or weak, which indicated that the ions were produced indoors rather than carried in from outdoors. Correlations between various water-soluble ions in indoor and outdoor PM 2.5 are discussed here, and it is suggested that the photocopier machine contributed little to the water-soluble ions indoors. Ion balance calculations indicated that the anions and cations in the photocopy room and outdoor environment shared an origin, but part of the anions and cations in the common office room and student dormitory originated indoors. The linear regression slopes (anion/cation) are all lower than 1, with the anion deficits probably affected by the absence of data on F

“…3 Therefore, to protect both human health and the environment, it is important to control the emissions at the source and implement effective reduction measurements on local, regional and global scales. 4,5 Comprehensive investigations are required to evaluate which sources contribute to the total mass of organic aerosols. 6,7 Source apportionment techniques, such as chemical mass balance (CMB) and positive matrix factorization (PMF) receptor models, have been developed and used successfully for quantitative identification of sources for organic pollutants in aerosols.…”
