“…[26] The inhalation reference concentration (RfCi) and oral reference dose (RfDo) values, along with other required parameters for HQ calculations, given below were based on previous reports. [25,27] The hazard index (HI) (Equation ( 7)) was the sum of HQ and was used to evaluate the potential risk to the human when more than one potentially toxic metal was involved. Again, if HI < 1, it was believed that the exposed population was unlikely to experience non-carcinogenic health effects, while there was the possibility that non-carcinogenic impacts might occur in the residents when HI > 1.…”

This study aims to determine the health risks from some potentially toxic metal content of PM 10 on the residents of Hamadan, Iran. The mean concentration of PM 10 is 122.55 µg m -3 , and for Pb, Cd, and Cr it is 7.44, 1.78, and 2.72 ng m -3 , respectively. PM 10 levels of 22% of the samples are higher than the National Ambient Air Quality Standards (NAAQS). Pb and Cd levels are within the standard/guideline limits, whereas Cr levels exceed the guideline value in 53% of the samples. Health risks from toxic elements of PM 10 are estimated using hazard quotient (HQ) and hazard index (HI), and the cancer risk is evaluated based on lifetime daily cancer risk (CR). Both HQ and HI are <1; furthermore, children are at an increased health risk according to obtained HQ and HI values. Cr and Cd present potentially carcinogenic health risks, while CR from Pb is within the acceptable limits. Although both HQ and HI are obtained <1, conducting such health risk assessment studies really is needed to determine the air quality in different cities such as Hamadan and the obtained data can be used as general guidance for decision makers to manage the air quality.

“…Recently, Liu et al 2019 Reported concentrations for various elements during fireworks events in different countries for coarse (PM2.5-10 and PM10) (Moreno et al, 2007;Pongpiachan et al, 2018;Tsai et al, 2012;Vecchi et al, 2008) and fine (PM2.5) PM (Kong et al, 2015b;Liu et al, 2019;Tsai et al, 2012) (all values in ng/m 3 ). Please note that the studies represented here used various methodologies for element speciation.…”

“…Relative abundance analysis (R a ) is the ratio of the percentage of the target metallic elements in PM 2.5 of the EDs over that in the NDs, as shown in Eq. (1) to identify the enriched metal influenced by the firecracker burning but not by other pollution sources (Kong et al, 2015;Liu et al, 2019).…”

“…Thus, the sources of these chemical species were attributed to coal-burning boilers. In Category III, the highest loading was identified as NO 3 -, SO 4 2-, Ca 2+ , and K + , and followed by NH 4 + , Mg, Ti, and Al, which were characterized as road dusts (Li et al, 2012;Liu et al, 2019). The mean concentration (2.6 µg m -3 ) of PM 2.5 from the road dusts accounted for 23.0% of the total mass of PM 2.5 .…”

“…During the festival, the concentration of various chemical indicators of firework displays increases dramatically. For instance, in Beijing, Ba, Cu, Pb as color agents, and propellants increased nearly 100 times (Liu et al, 2019). Kong et al (2015) found that organic carbon, elemental carbon, ammonium, potassium, and silicon accounted for nearly 70% of total PM 2.5 in the Spring Festival in Nanjing.…”

The randomness of firecracker-burning site and the overlapping impact of multi-sources makes the source apportionment of PM 2.5 during the firecracker burning events more difficult. To investigate the influences of the downwind distance to the firecracker-burning site on the temporospatial distribution of PM 2.5 and public health risk, PM 2.5 were sampled at three sites adjacent to a fixed firecracker-burning route accompanied with annual pilgrimage activity during the Lantern Festival in Taitung, Taiwan, which had a low background PM 2.5 concentration. The metallic elements, water-soluble ions, carbonaceous contents were analyzed. The potential sources were identified using positive matrix factorization. Finally, the health risks were assessed by calculating the hazard quotient and incremental lifetime carcinogenic risk, respectively. The results showed that the average concentration of PM 2.5 on the event days increased by approximately five-fold compared to the non-event days. The increase of chemical components varied significantly from the distance to the burning site. The concentrations of K, Fe, Al, Mg, K + , Cland OC rose by 6-14 times at one site close to a site with intensive firecracker burning, while increased by 2-6 times at one site far away from the firecracker burning sites. The PM 2.5 increment on the event days was mostly attributed to firecracker burning, kitchen fumes, and mobile sources. The health risk assessment results showed that the hazard index differed between the sampling sites. Furthermore, the cancer risk of one site close to the firecracker burning site was over the threshold, while that far away from the site was below the threshold.
