“…The descriptive statistics of the 12 studied elemental contents in PM 2.5 are listed in Table 2 . In general, the contents of Al, Pb, and Mn were generally higher than those of the other elements in PM 2.5 , which were consistent with previous studies [ 17 , 25 , 44 ]. The metal concentrations in PM 2.5 varied over sampling sites.…”

“…The three major pathways of residential exposure to heavy metals in PM 2.5 are ingestion, inhalation, and dermal contact [ 16 , 25 ]. The exposure dose through each of the three pathways was calculated according to the Human Health Evaluation Manual (Part A), Supplemental Guidance for Dermal Risk Assessment (Part E), and Supplemental Guidance for Inhalation Risk Assessment (Part F) [ 26 , 27 , 28 ].…”

The spatiotemporal characteristics and human health risks of 12 heavy metals (Al, As, Be, Cd, Cr, Hg, Mn, Ni, Pb, Sb, Se, and Tl) in fine particulate matter (PM2.5) in Zhejiang Province were investigated. The annual average PM2.5 concentration was 58.83 µg/m3 in 2015 in Zhejiang. Element contents in PM2.5 varied greatly with the season and locations. Al, Pb, and Mn were the most abundant elements among the studied metal(loid)s in PM2.5. The non-carcinogenic risks of the 12 elements through inhalation and dermal contact exposure were lower than the safe level for children and adults. However, there were potential non-carcinogenic risks of Tl, As, and Sb for children and Tl for adults through ingestion exposure. The carcinogenic risks from As, Be, Cd, Cr, Pb, and Ni through inhalation exposure were less than the acceptable level (1 × 10−4) for children and adults. Pb may carry a potential carcinogenic risk for both children and adults through ingestion. More attention should be paid to alleviate non-carcinogenic and carcinogenic health risks posed by particle-bound toxic elements through ingestion exposure.

“…Compared with the results obtained in the other cities, the HQ values of As, Cd, Cr, and Ni in all studied area were considerably lower than those in Chengdu (Li et al, 2016b) but higher than those in Tianjin (Chen et al, 2015). The HQ values of Mn (0.32-0.64) in three sites were lower than that of the central area site in Baotou (0.90) (Li et al, 2016a). The HQ values of As in Luoyang were higher than those of the vehicle inspection workers in Beijing (Li, 2013).…”

The sites of Luoyang, Zhengzhou, and Pingdingshan in Henan, China were selected to investigate the chemical compositions of fine particulate matter (PM 2.5 ). A total of 165 PM 2.5 samples from the three sites were collected from October 2014 to July 2015. Water-soluble inorganic ions, elemental carbon and organic carbon, and other elements in PM 2.5 were analyzed by ion chromatography, carbon analyzer, and inductively coupled plasma mass spectrometry, respectively. Results showed that the annual average concentrations of PM 2.5 in the three sites were significantly higher than the Chinese national ambient air quality standard. The seasonal average of PM 2.5 concentration varied with the lowest concentrations of PM 2.5 in summer. Among these sites, the highest concentrations of SO 4 2-and NH 4 + ions were observed in Luoyang with the highest concentration of NO 3 -detected in Zhengzhou. SO 4 2-, NO 3 -and NH 4 + ions occurred as (NH 4 ) 2 SO 4 and NH 4 NO 3 . For seasonal variation, the highest concentrations for Al, Fe and Ca were observed during spring in Pingdingshan and autumn in Zhengzhou and Luoyang, respectively. Enrichment factor (EF), as an indicator, is commonly used to evaluate the contribution of anthropogenic sources, and high EFs of Zn, Cu, and Cd in PM 2.5 indicate the extent of air pollution, which is generally caused by emissions of vehicles and industries. Risks posed by heavy metals on human health were assessed. The hazard index, which was used to assess the overall potential for noncarcinogenic effects, was higher than 1 in the three sites, indicating that V, Cr, As, Mn, Cd, Co, and Ni may cause accumulative noncarcinogenic health effects on humans, without the noncancer effect of each heavy metal significant. Cr in PM 2.5 is a potential carcinogenic risk when inhaled by adults. Overall, the results indicate that PM 2.5 pollution must be considered seriously in three cities.

Honeybees have been proposed and used as bioindicators for the last few decades, because of their nature. Until now they have mostly been used to determine the present pollution and to distinguish the differences between the sampling locations and the sampling periods. With the use of multivariate statistical methods honeybees can also be used to distinguish the origin of this pollution. In this study the concentrations of Al,
