“…Positive matrix factorization (PMF) is an effective and frequently used source apportionment method, which is based on factor analysis. [24,25] In the PMF model, the sample concentration matrices are first decomposed into contribution matrices and profile matrices by factorization, then the emission inventories were collected through the obtained profile information, and the pollution sources and their contribution rates are identified finally. [26] The expression of PMF is as follows [27] x…”

In this study, a total of 26 surface sediments samples are collected from the Liao River estuary wetland, China. The concentration, potential ecological risk, and source apportionment of potentially toxic metals including Sr, Zn, Cr, Ni, Pb, Cu, and As in different seasons are analyzed. The average concentrations of potentially toxic metals are below the first class of Chinese marine sediment quality standard. There is no significant difference in the concentrations of potentially toxic metals in the sediments collected in June and November. The concentrations of potentially toxic metals in the periphery of the nature reserve are higher than those in the core area of the nature reserve. The average enrichment factors of As, Pb, Cu, Ni, Zn, and Cr are about 1, classified as minimal enrichment. The average enrichment factor of Sr is >2, which corresponds to moderate enrichment. The individual (E r ) and total potential ecological risks (RI) of potentially toxic metals are low. The positive matrix factorization model suggested that the potentially toxic metals in surface sediments in June are dominantly from atmospheric deposition, industrial discharges, natural sources, and traffic emission. However, the traffic emission source is replaced by agricultural production and metal smelting activities in November.

IntroductionRapid urbanization and industrialization provide benefits to the economy and society but also cause pollution of soil, water, and air and even pose risks to ecosystems [1][2][3][4]. Heavy metals refer to metals and metalloids, such as Cr, Cu, Zn, As, Cd, Ni, Pb, and Hg, whose densities are > 5 g•cm −3 [5][6]. Heavy metals in soil are difficult to degrade and enter the food chain. Consequently, heavy metal pollution will not only reduce the quality of the soil environment but also pose a threat to human health [7][8][9][10][11][12]. For instance, exposure to As can lead to dermal lesions, skin cancer, peripheral neuropathy, and peripheral vascular disease

“…Polycyclic aromatic hydrocarbons (PAHs) are the main group of organic pollutants associated with PMs which consist of two or more fused benzene rings (Luo et al 2019;Wu et al 2014;Hassanvand et al 2015). PAHs both in gas and particle phase can emitted to the environment from natural processes such as incomplete combustion of organic matters, volcanic eruptions and forest res (Wang et al 2008).…”

Particulate matters (PMs) and their associated chemical compounds such as polycyclic aromatic hydrocarbons (PAHs) are important factors to evaluate air pollution and its health impacts particularly in developing countries. Source identi cation of these compounds can be used for air quality management.The aim of this study was to identify the sources of PM 2.5 -bound PAHs in Isfahan city, a metropolitan and industrialized area in central Iran. The PM 2.5 samples were collected at 50 sites during one year. Source identi cation and apportionment of PAHs were carried out using diagnostic ratios (DRs) of PAHs and positive matrix factorization (PMF) model. The results showed that the concentrations of PM 2.5 ranged from 8 to 291 µg/m 3 with an average of 60.2 ± 53.9 µg/m 3 whereas the sum of concentrations of the 19 PAH compounds ( PAHs) ranged from 0.3 to 61.4 ng/m 3 with an average of 4.65 ± 8.54 ng/m 3 . The PAH compounds showed their highest and lowest concentrations in fall and summer, respectively. Applying DRs, suggested that the source of the PAHs were mainly from fuel combustion. The main sources identi ed by the PMF model were gasoline combustion (28 %) followed by diesel combustion (22 %), natural gas combustion (17 %), evaporative-uncombusted (13 %), industrial activities (11 %), and unknown sources (9 %). The results revealed that in addition to transportation and industrial activities, combustion of natural gas for heating systems as one of the PAHs source in PM 2.5 should be managed in the metropolitan area.
