“…The study by Feng et al ( 2022 ) shows that Hg is a persistent and bio-accumulative metallic pollutant that represents a serious threat to the ecological system and human health, even in minimal concentrations. Yet more when the risk of suffering from the harmful health effects of Hg is mainly high where fish are the basis of food (Zhou et al, 2022 ). Our results add information on the assessment of human health risks in gold mining areas in the Amazon region.…”

“…The results obtained by Jiménez-Oyola et al, ( 2021 ), suggest that the greatest risk of exposure for both adults and children to inorganic Hg present in contaminated water bodies is through incidental ingestion of water. On the other hand, in work environments, where Hg amalgamation is performed, the main exposure route for people is the inhalation of elemental Hg vapors (De Miguel et al, 2014 ; Zhao et al, 2022 ). Moreover, fish consumption has been reported as an important route of entry of methylmercury into the human body, mainly in mining areas (De Miguel et al, 2014 ; Marrugo-Negrete et al, 2020 ).…”

Illegal gold mining activities have contributed to the release and mobilization of Hg and environmental degradation in many parts of the world. This study aims to determine the concentration of Hg in five provinces of the Amazon Region of Ecuador, in addition to assessing the risk to human health of exposed populations, applying deterministic and probabilistic methods. For this purpose, 147 water samples were collected in rivers and streams crossing and/or located near mining areas. As a result, 100% of the samples analyzed exceeded the maximum permissible limit (MPL) according to the water quality criteria for the preservation of aquatic life of the Ecuadorian regulations, while 7% of the samples exceeded the MPL for drinking water. On the other hand, considering the European Environmental Quality Standard (EQS) for surface water bodies, in our study, 100% of the samples exceed the maximum permissible limit (0.07 µg/L), and with respect to the Canadian water quality guidelines, 35% of the samples exceed the permissible limit (0.001 mg/l) for drinking water, and 100% of the samples exceed the limit for life in water bodies (0.0001 mg/l). The risk assessment revealed that the probability of developing adverse health effects from exposure to Hg is below the recommended limits according to the probabilistic assessment; this is in relation to the criterion of residential and recreational use of water resources. However, it was identified that the child population doubles the acceptable systemic risk level according to the results of the deterministic assessment in the residential scenario. This information can be used by decision-makers to implement strategies to reduce Hg contamination and exposure of the population in Ecuadorian Amazonian rivers.

“…The results of the study showed severe arsenic contamination of the soil at the site, and the mean value of the potential ecological risk index (Er) was estimated to be 606, indicating a potentially serious ecological risk and the need for the remediation of the contaminated site. Zhao et al [14] used a three-dimensional model sandbox to simulate the contamination transport of the heavy metal Cr (VI) in the unsaturated zone and aquifer. Wu et al [10] studied the contamination characteristics and ecological risk of heavy metals in the soil of a construction waste landfill.…”

Human-Health and Environmental Risks of Heavy Metal Contamination in Soil and Groundwater at a Riverside Site, China

et al. 2022

The contaminated site is considered a high-risk pollution source due to the accumulation of industrial waste and wastewater, which affects the soil and groundwater environment. In this study, through soil and groundwater investigation, we outlined the characteristics of heavy metal contamination in the soil and groundwater of the contaminated site, assessed the health risk of the contaminated site to humans, and established a numerical model to predict the ecological and environmental risks of the site. The results of the study showed that the maximum contamination concentration of pollutants (lead, arsenic, cadmium) in the soil all exceeded the Chinese environmental standard (GB36600-2018, Grade II), that the maximum contamination concentration (cadmium, Cd) of the groundwater exceeded the Chinese environmental standard (GB14848–2017, Grade IV), and that the heavy metal pollution was mainly concentrated in the production area of the site and the waste-residue stockpiles. The total carcinogenic risk and non-carcinogenic hazard quotient of the site's soil heavy metal contaminants exceed the human acceptable limit, and there is a human health risk. However, the groundwater in the area where the site is located is prohibited from exploitation, and there is no volatility of the contaminants and no exposure pathway to the groundwater, so there is no risk to human health. The simulation prediction results show that, with the passage of time, the site groundwater pollutants as a whole migrate from south to north, affecting the northern surface water bodies after about 12 years, and there is a high ecological and environmental risk. The above findings provide a scientific basis for the study of the soil and groundwater at the riverside contaminated site.

“…Although PM2.5-bound MM are strongly studied in China (e.g., Liao et al, 2023;Zhou et al, 2023;Guo et al, 2022;Duan et al, 2021), the latter are poorly documented in Vietnam. In 2020, mean annual concentrations for As, Cd, Cr in PM2.5 were found at 6.2, 1.9, 9.4 ng m -3 , respectively (Nguyen et al, 2022), exceeding global guidelines for As and Cr (6.0 and 0.25 ng m -3 , respectively; WHO, 2021).…”
