“…4), the health risk results showed that the health risks of toxic elements from IS and CC were much higher than those from SIA. Previous studies showed that coal combustion sources in Beijing, Shanxi, and Jinan had higher respiratory exposure health risks, while the fugitive dust source in Liaoning contained higher levels of Pb, As, and Co (Zeng et al, 2021). It was related to the differences in PM2.5 pollution characteristics and source contributions in different cities.…”

“…In Figure 3c, the compositions with large contributions included heavy metal pollutants such as As (42.8%), Pb(33.8%), Cr (61.1%), Zn (58.9%), Cu (59.4%), Fe (38.3%), and Mn (40.1%). As, Pb, Cr, Fe and Mn are related to metal smelting and processing (Fang et al, 2021). Cu, Zn, and OC are used as tracers of a mixed source of traffic and industrial (Wang et al, 2020).…”

Abstract. Given the increasing complexity of the chemical composition of PM2.5, identifying and quantitatively assessing the contributions of pollution sources has played an important role in formulating policies to control particle pollution. This study provides a comprehensive assessment between PM2.5 chemical characteristics, sources, and health risks based on sampling data conducted over one year (March 2018 to February 2019) in Nanjing. Results show that PM2.5 exhibits a distinct variation across different seasons, which is primarily driven by emissions, meteorological conditions, and chemical conversion of gaseous pollutants. First, the chemical mass reconstruction shows that secondary inorganic aerosols (SIA, 62.5 %) and carbonaceous aerosols (21.3 %) contributed most to the PM2.5 mass. The increasing oxidation rates of SO2 and NO2 from summer to winter indicate that the secondary transformation of gaseous pollutants is strongly positively correlated with relative humidity. Second, the positive matrix factorization (PMF) method shows that identified PM2.5 sources include SIA (42.5 %), coal combustion (CC, 22.4 %), industry source (IS, 17.3 %), vehicle emission (VE, 10.7 %), fugitive dust (FD, 5.8 %) and other sources (1.3 %). The Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model and the concentration-weighted trajectory (CWT) analysis are used to further explore different spatial distributions and regional transport of sources. High emissions (10-11 μg·m−3) of SIA and CC distribute in Nanjing and central China in winter. Moderate emissions (8-9 μg·m−3) of IS and VE are potentially located in the north of Jiangsu, Anhui, and Jiangxi. The PM2.5 pollution from long-range transport is attenuated by meteorological conditions and ocean air masses. Finally, the health risk assessment indicates that the carcinogenic and non-carcinogenic risks of toxic elements (Cr, As, Ni, Mn, V, and Pb) mainly come from IS, VE, and CC, which are within the tolerance or acceptable level. Although the main source of pollution in Nanjing is SIA at present, we should pay more attention to the health burden of vehicle emissions, coal combustion, and industrial processes.

“…In addition, most of the Mn risk assessment studies are based on estimating exposure from different scenarios and stationary measurements data (Fadel et al, 2022;Hernández-Pellón et al, 2018). Furthermore, there is a limited number of datasets for environmental personal exposure monitoring (Fang et al, 2021;Li et al, 2022).…”

“…PAHs are products of incomplete combustion, and prolonged exposure to PAHs can lead to a range of cancer-related health problems [7,8]. PM 2.5 and PM 10 combined with PAHs can cause different health effects [9][10][11][12][13]. Currently, long-term and synchronous monitoring of PM 2.5 -and PM 10 -bound PAHs is very limited, especially in developing countries suffering from severe air pollution [1].…”

To understand the enrichment concentrations, compositional characteristics, and sources of polycyclic aromatic hydrocarbons (PAHs) in atmospheric particulate matter (PM) and organic film, PM 2.5 , PM 10 , and organic film on glass surfaces were collected from eight sampling sites in central urban, suburban, and rural Shanghai. Sixteen priority-controlled PAHs were investigated using gas chromatography-mass spectrometry, and mass concentrations, compositional differences, and pollution sources of PAHs in PM and organic film were analyzed. The results indicate that under good air conditions, 2.5-10 μm particles are relatively abundant in the atmosphere; during haze periods, PM is generally less than 2.5 μm. Furthermore, PAHs tend to adsorb on PM less than 2.5 μm. Except at Shengang (SG), 4-ring PAHs are particularly abundant in PM, while 2-and 3-ring PAHs are particularly abundant in organic film. The K FA of low molecular weight PAHs is higher than the K OA , indicating that these monomer PAHs have achieved dynamic equilibrium between the organic film and the atmosphere. Source identification results show that PAHs in PM and organic film are generated by vehicle exhaust, domestic exhaust gas, and ground dust.
