“…To determine the inhalation risk of PM 2.5 caused by Cd and Pb in the study area, a health risk assessment was carried out according to the guidelines of the USEPA. Because of the influence of different exposure doses (bioavailable concentration, deposition concentration, and both factors) on the assessment results, risk assessment of different doses and probability analyses were carried out [ 21 , 28 , 33 , 65 , 74 ].…”

PM2.5 can deposit and partially dissolve in the pulmonary region. In order to be consistent with the reality of the pulmonary region and avoid overestimating the inhalation human health risk, the bioaccessibility of PM2.5 heavy metals and the deposition fraction (DF) urgently needs to be considered. This paper simulates the bioaccessibility of PM2.5 heavy metals in acidic intracellular and neutral extracellular deposition environments by simulating lung fluid. The multipath particle dosimetry model was used to simulate DF of PM2.5. According to the exposure assessment method of the U.S. Environmental Protection Agency, the inhalation exposure dose threshold was calculated, and the human health risk with different inhalation exposure doses was compared. The bioaccessibility of heavy metals is 12.1–36.2%. The total DF of PM2.5 in adults was higher than that in children, and children were higher than adults in the pulmonary region, and gradually decreased with age. The inhalation exposure dose threshold is 0.04–14.2 mg·kg−1·day−1 for the non-carcinogenic exposure dose and 0.007–0.043 mg·kg−1·day−1 for the carcinogenic exposure dose. Cd and Pb in PM2.5 in the study area have a non-carcinogenic risk to human health (hazard index < 1), and Cd has no or a potential carcinogenic risk to human health. A revised inhalation health risk assessment may avoid overestimation.

“…Two suspended sediments collected at the upstream point (ME-A 11-May-2016 10 PM and ME-A 12-May-2016 4 PM samples) were characterised by SEM-EDX (form, chemical composition) at the Centre de MicroCaract erisationRaimondCastaing (Toulouse) and by X-Ray Diffraction at the GET laboratory (Toulouse). All the details about the methods are reported in Blondet et al (2019) and Blotevogel et al (2018).…”

Copper export and mobility in acid mine drainage are difficult to understand with conventional approaches. Within this context, Cu isotopes could be a powerful tool and here we have examined the relative abundance of dissolved (<0.22 mm) Cu isotopes (d 65 Cu) in the Meca River which is an outlet of the Tharsis mine, one of the largest abandoned mines of the Iberian Pyrite Belt, Spain. We followed the chemical and isotopic composition of the upstream and downstream points of the catchment during a 24-h diel cycle. Additional d 65 Cu values were obtained from the tributary stream, suspended matter (>0.22 mm) and bed sediments samples. Our goals were to 1) assess Cu sources variability at the upstream point under contrasted hydrological conditions and 2) investigate the conservative vs. non conservative Cu behavior along a stream. Average d 65 Cu values varied from À0.47 to À0.08‰ (n ¼ 9) upstream and from À0.63 to À0.31‰ downstream (n ¼ 7) demonstrating that Cu isotopes are heterogeneous over the diel cycle and along the Meca River. During dry conditions, at the upstream point of the Meca River the Cu isotopic composition was heavier which is in agreement with the preferential release of heavy isotopes during the oxidative dissolution of primary sulfides. The more negative values obtained during high water flow are explained by the contribution of soil and waste deposit weathering. Finally, a comparison of upstream vs. downstream Cu isotope composition is consistent with a conservative behavior of Cu, and isotope mass balance calculations estimate that 87% of dissolved Cu detected downstream originate from the Tharsis mine outlet. These interpretations were supported by thermodynamic modelling and sediment characterization data (X-ray diffraction, Raman Spectroscopy). Overall, based on contrasted hydrological conditions (dry vs flooded), and taking the advantage of isotope insensitivity to dilution, the present work demonstrates the efficiency of using the Cu isotopes approach for tracing sources and processes in the AMD regions.

“…As per the World Health Organization (WHO) estimation, seven million people die each year due to poor air quality (WHO 2014). It is primarily as a result of the concentration of pollutants such as NO 2 , NH 3 , PM 2.5 , and SO 2 CO. from different human actions such as mining activities, the process of manufacturing, transportation, residential cooking, biomass, and waste burnings (Kinnon et al 2019;Li et al 2019;Blondet et al 2019;Koçak and Kızılkaya 2020;Dedeoğlu et al 2021). During the past two decades, numerous studies highlighted that polluted air incites short-term and long-term health issues such as asthma, cancer, premature deaths, and cardiovascular mortality, among humans (Bowatte et al 2017;Deng et al 2017;Zhang et al 2017;Gilderbloom et al 2020;Karuppasamy et al 2020).…”

The outbreak of the COVID-19 pandemic has adversely affected all aspects of life and poses a severe threat to human health and economic development. New York City administration enacted a strict isolation decision at the end of March 2020 to tackle the COVID-19, creating a unique opportunity to assess air quality. Therefore, we investigated the impact of the lockdown on air quality in New York City. We evaluated the air pollutants concentration, i.e., PM 2.5 , CO, NO 2 , SO 2 , and O 3, during the lockdown and compared them with pre-COVID-19. We explored the first phase of lockdown through a spatial approach, then formulated the air quality index (AQI) of each pollutant before and during the lockdown. Our findings revealed that (1) there was a significant decline in the concentration level of PM 2.5 from 10.3 to 4.0 μg/m 3 during phase one of lockdown. (2) NO 2 concentrations have been decreased by up to 52% in 1st phase of lockdown. (3) O 3 concentration has been increased by 44.4%. (4) Brooklyn, Manhattan, Queens, and Staten Island County encountered 18.75%, 55.62%, 47.14%, and 47% diminution in AQI due to lockdown as compared to 2018, respectively. Our key findings can provide critical environmental implications for policymakers, researchers, academics, and the US government.
