This study aims to increase our current knowledge on the concentration of particulate-bound mercury (PBM) in urban environments of three Iranian cities, where high concentrations of dust particles can act as carriers for mercury transport and deposition. A total of 172 dust samples were collected from Ahvaz, Asaluyeh, and Zabol residential houses and in outdoor air and were analyzed for total mercury content. Ahvaz is a highly industrialized city with large metallurgical plants, refineries, and major oil-related activities, which were assumed to contribute to elevated contents of PBM in this city. Very high levels of Hg contamination in Ahvaz indoor dust samples were calculated (Contamination Factor: CF > 6). Sampling sites in Asaluyeh are influenced by Hg emissions from the South Pars Gas Field. However, the results revealed a relatively lower concentration of PBM in Asaluyeh, with a low-to-moderate level of Hg contamination. This is likely ascribed to the lower content of total mercury in hydrocarbon gases than crude oil, in addition to the absence of metal smelting plants in this city compared to Ahvaz. Zabol, as a city devoid of industrial activity, presented the lowest levels of PBM concentration and contamination. Indoor dust in Ahvaz showed considerable potential to cause a non-carcinogenic health risk for children, mainly through the inhalation of PBM, while the health risk for other cities was below safe limits. The trend of health risk was found in the order of indoor > outdoor and children > adults in all studied cities.

“…Particular attention has been paid in recent years to the risk of mercury poisoning in the general population, linked to the wearing of dental amalgam containing mercury, but also silver, copper, tin, and zinc. Indeed, several studies have shown a release of mercury from dental amalgams into the oral cavity, which is then inhaled and then absorbed [19,20]. The disposal practices used are most often: open burning, discharge into drains, routing, and burial of waste in Mbeubeuss Lindfil, collection and storage with household waste among many others.…”

ContextNowadays, human activities of all kinds have led to widespread pollution. Pollution caused by the release of harmful substances such as metals found in the environment and or in processed food is an ongoing health concern. Some of these released metals have a known biological role whereas others such as cadmium (cd), mercury (Hg), arsenic (As) and lead (Pb) have no known biological role and cause harmful effects even at low doses. Mercury (Hg) is an element naturally present in the environment, mainly resulting from volcanic actions, weathering of rocks, forest fires, etc. [1]. The problem of the toxicity of Hg is mainly justified by human activities resulting in the release of large amounts of mercury into the environment, which can then circulate freely for thousands of years [2][3][4][5]. Mercury pollution is of international concern because of its considerable potential danger

“…People would be exposed to them via multi-pathway exposure (Sun et al, 2019). HMs in particulates, such as chromium (Cr), Zinc (Zn), copper (Cu), lead (Pb), nickel (Ni), cadmium (Cd), and arsenic (As), have already been proved to lead to significant threats to ecosystems and cause carcinogenic and non-carcinogenic risk for people (Doabi et al, 2018;Men et al, 2018;Sahakyan et al, 2019).…”

Evaluating heavy metals contamination in campus dust in Wuhan, the university cluster in Central China: distribution and potential human health risk analysis

et al. 2022

The potential health risk of heavy metals (HMs) in campus dust may threaten the health of thousands of students, teachers, and their families in Wuhan, the university cluster in Central China every day. In this research, the pollution characteristics and health risk with HMs was the first time presented in campus dust from the canteen, playground, dormitory, and school gate to date. The average HMs concentration in campus dusts ranked Pb (83.5 mg kg-1) > Cu (70.2 mg kg-1) > Zn (47.2 mg kg-1) >Cr (46.0 mg kg-1) > Ni (22.7 mg kg-1) > As (15.2 mg kg-1) > Cd (3.38 mg kg-1).The HMs would more likely to accumulate in dormitory dust and canteen dust. In the downtown area, Zn, As, and Cd had been preliminarily identified from fossil fuel combustion and natural geochemical processes. Cu and Pb would source from cooking and traffic transportation. Ni and Cr would likely reflect the contributions of natural soil weathering. Although, no significant non-carcinogenic health risks were found to students or teachers from campus dust. Their children would more likely to exposure health risks when eating in the canteen, playing on the playground, or walking around the school gate. While the incremental lifetime cancer risk values revealed respiratory intake of HMs does not pose a carcinogenic risk on the campus.
