“…The highest HQ in children and adults was found to be related to Cr, and total HI in children was higher than those of the adults, which is similar to our findings. In the study by Parvizimehr et al., [ 49 ] 30 samples were collected in total and corresponding carcinogenic and non‐carcinogenic health risks were calculated. The results showed that excess lifetime cancer risk (ELCR) from Cr for children was 1.20 × 10 ‒2 , which exceeds the proposed value by the US EPA.…”

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.

“…NIST SRM 1648a urban dust contains 6550 mg/kg of Pb, whereas KRISS urban dust contains only less than 150 mg/kg. Ni and Pb elements are related mainly to the combustion of fossil fuels, and even after the ban on the use of additives, these elements are still present in airborne PM [3,8,19,52,53]. Si is a typical soil component (Earth's crust) similar to Al, Ca, Fe, and Mg, and its contribution comes from soil-derived particles [1,54].…”

“…Cd, As, and Pb are particularly known to be associated with industrial activities, such as heavy and metallurgical industry, coal burning, and copper production [2,53,58]. In addition, Cd and Cr are elements of industrial origin that enter the air due to the resuspension of soil dust [52]. Hg comes mostly from industrial use, coal combustion, and waste incineration [60].…”

Application of k0-INAA Method in Preliminary Characterization of KRISS Urban Airborne Particulate Matter Certified Reference Material

We report comprehensive elemental composition studies on the average urban airborne particulate matters (PMs) collected in the Greater Seoul area, Korea, in 2019 to identify regional and chronological characteristics of the sample as a candidate for certified reference material (CRM), using k0-based single comparator instrumental neutron activation analysis (k0-INAA). The method was successfully validated by comparing the analysis result of a similar matrix CRM (SRM 1648a urban particulate matter) of National Institute of Standards and Technology, USA, with corresponding certified values. The same methodology was applied to determine various elements in candidate environmental materials for future CRM development, including the urban PMs and incineration ashes, to investigate the possibility of using k0-INAA for certification of relevant reference materials. In total, 46 elements in the urban PM sample were analyzed and their concentration levels were compared with the urban PMs collected in the 1970s in St. Louis, USA. Urban PMs of Korea Research Institute of Standards and Science in 2019 contain significantly lower levels of hazardous elements, such as As, Cd, Cr, Hg, and Pb, as compared to those of the 1970s, which can be attributed to the reduced air pollution by environmental regulation and technological innovation. The potential major source of urban airborne PMs was also discussed.

“…Identifying the source of heavy metals is critical for preventing environmental pollution and protecting human health ( Tang et al, 2013 ). Recent research on heavy metals found in dust fall has mainly focused on cities, parks, and roads ( Taylor, 2015 ; Parvizimehr et al, 2020 ; Zheng et al, 2010 ). Direct dust sample collection methods using air samplers can be used to determine heavy metal concentrations per unit area in a short period of time ( Mohsen, Ahmed & Zhou, 2018 ; Olawoyin et al, 2018 ), and indirect methods using dust tanks, collected rainwater, soil, plant leaves, or bark as biological indicators can be used to determine the long-term concentration of heavy metals in dust ( Uchiyama et al, 2019 ; Miri et al, 2016 ; Gholizadeh et al, 2019 ).…”

China’s desert steppe is the transition zone between the grasslands in central China and the arid desert. Ecological security in this region has long been a subject of debate, both in the local and academic communities. Heavy metals and other pollutants are readily released during industrial production, combustion, and transportation, aggravating the vulnerability of the desert steppes. To understand the impact of industrial activiteis on the heavy metal content of dust fall in the desert steppe, a total of 37 dust fall samples were collected over 90 days. An inductively-coupled plasma mass spectrometer (NexION 350X) was used to measure the concentration of heavy metals Cu, Cd, Cr, Pb, Mn, Co, and Zn in the dust. Using comprehensive pollution index and multivariate statistical analysis methods, we explored the characteristics and sources of heavy metal pollution. We also quantitatively assessed the carcinogenic risks of heavy metals resulting from dust reduction with the help of health risk assessment models. The heavy metals’ comprehensive pollution index values in the study area’s dust fall were ranked as follows: Zn > Cd > Pb > Mn > Cu > Co > Cr. Among these, Zn, Cd, and Pb were significant pollution factors in the study area, and were affected by industrial production and transportation. The high pollution index was concentrated in the north of the research industrial park and on both sides of a highway. The seven heavy metals’ total non-carcinogenic risk index (HI) values were ranked as follows: Mn > Co > Pb > Zn > Cr > Cu > Cd (only the HI of Mn was greater than one). Excluding Mn, the non-carcinogenic and carcinogenic risk index values of the other six heavy metals were within acceptable ranges. Previous studies have also shown that industrial transportation and production have had a significant impact on the heavy metal content of dust fall in the desert steppe.
