“…According to the Chinese National Soil Contamination Survey Report, approximately 33.4% of soil around mining sites were contaminated with HMs (Mee and Mnr, 2014). Among them, arsenic (As) and lead (Pd) commonly co-exist in high concentrations due to mining and smelting of mineral ores (Wang et al, 2020a;Fernandez-Macias et al, 2020), and threaten soil, plant and human health. In paddy soil, excess As and Pb can reduce soil quality, stunt plant growth, and ultimately affect human health through the food chain (Du et al, 2018;Rai et al, 2019).…”

Mining activity is a growing environmental concern as it contributes to heavy metals (HMs) pollution in agricultural soils. Microbial communities play an important role in the biogeochemical cycling of HMs and have the potential to be used as bioindicators. Arsenic (As) and lead (Pb) are the most hazardous HMs and are mainly originated from mining activities. However, spatial variation in microbial community in response to As and Pb contamination in paddy soils remains overlooked. In this study, the biological and chemical properties of sixteen soil samples from four sites (N01, N02, N03, and N04) near a Pb-Zn mining site at different As and Pb levels were examined. The results showed that soil pH, total As and Pb, bioavailable As and Pb, nitrate-nitrogen (NO3−-N) and ammonia-nitrogen (NH4+-N) were the most important factors in shaping the bacterial community structure. In addition, significant correlations between various bacterial genera and As and Pb concentrations were observed, indicating their potential roles in As and Pb biogeochemical cycling. These findings provide insights into the variation of paddy soil bacterial community in soils co-contaminated with different levels of As and Pb.

“…On an international level, a diverse study that evaluated the risk associated with the presence of MEL reported similar results to the ones obtained in the present research work. In San Luis Potosí, Mexico, the principal sources of toxic elements in the contaminated sites by MEL correspond to tailings deposits, dams, and slag deposits from which the pollutants can mobilize or be transported through the wind or runoff water and affect great soil extensions [5,52,53]. Moreover, in Zlata Idka-Slovenian, a study reported a high carcinogenic risk for the residents due to the high concentrations of As in soils, water, and vegetables [9].…”

“…The absence of clear regulations has led the accumulation of MEL in mining zones worldwide. There are polluted areas due to the mining activities that have been carried out for centuries in different countries such as Peru [1][2][3][4], Mexico [5], Chile [6], South Africa [7], Ghana [8], Slovakia [9], Korea [10], Spain [11], and Ecuador [12][13][14][15][16]. Moreover, numerous MEL have been reported in Latin American countries such as Bolivia, Chile, Colombia, and Peru [17].…”

Mining environmental liabilities (MEL) are of great concern because of potential risks to ecosystems and human health. In this research, the environmental risk (RI) related to MEL existing in three artisanal and small-scale gold-mining areas of Ecuador was evaluated. For this purpose, data of 167 MEL including landfills, mining galleries, tailing deposits, and mineral processing plants from Macuchi, Tenguel–Ponce Enriquez, and Puyango mining areas, were analyzed. The risk assessment related to the presence of waste deposits was carried out based on the methodology proposed by the Spanish Geological Survey. Moreover, the procedure outlined in the Environmental Risk Assessment Guide of the Ministry of Environment of Peru for nonwaste deposits was applied. The highest RI values were identified in Puyango and Tenguel–Ponce Enriquez. Thus, they were both categorized as priority control areas requiring intervention and rehabilitation plans. The MEL that require a high level of intervention include waste deposits and mine entrances associated with potentially toxic elements. Moreover, the point risk maps showed that rivers in the studied areas have a potential pollution risk. This study provides risk levels associated with MEL in mining areas from Ecuador. This information could be used for environmental management and pollution mitigation.

“…Los resultados obtenidos presentan niveles de riesgo más bajos a los descritos en estudios similares en Estados Unidos, Canadá, China e India (Laskar et al, 2015;Morales et al, 2000;Zhang et al, 2018Zhang et al, , 2020. A nivel regional se han realizado evaluaciones de riesgo por arsénico en México y Argentina; sin embargo, el modelo para la estimación difiere del utilizado en el presente estudio, por lo cual, los resultados no son comparables, ambos casos describen un exceso de riesgo para las poblaciones expuestas (Fernández-Macías et al, 2020;Leonarduzzi et al, 2020;Martínez-Acuña et al, 2016;Mendoza et al, 2017;Navoni et al, 2014).…”

Introducción: El arsénico, elemento que puede ser nocivo para la salud humana, es abundante en el ambiente. Fue una de las primeras sustancias reconocidas como cancerígenas y su presencia en el agua es común en América Latina. Sus niveles en fuentes de agua son relevantes para la toma de decisiones y control sanitario. Este estudio es el primero en América Latina con un modelo matemático de riesgo y carga de enfermedad. Objetivo: Evaluar la exposición a niveles bajos de arsénico en trabajadores agrícolas, de una cuenca costarricense, con esta nueva técnica. Métodos: Muestreamos arsénico en tres puntos a lo largo del río Purires, Cartago, entre septiembre de 2011 y agosto de 2012. Usamos estimaciones de “valor censurado”; evaluación de riesgos con modelos exponenciales cuadráticos y simulaciones de Monte Carlo para determinar el riesgo de cáncer, según tipo y vía de exposición durante el riego, para trabajadores agrícolas. Resultados: Las concentraciones no difirieron por sitio, pero fueron mayores en la época seca. El nivel de riesgo y la carga de enfermedad no fueron aceptables. La carga de enfermedad es un indicador más riguroso que el cálculo individual de probabilidad. Nuestro nivel de riesgo estimado es bajo en comparación con estudios hechos fuera de la región, pero no es comparable con trabajos anteriores en América Latina, basados en un método diferente. Conclusión: Hace una década, en la cuenca Purires, las concentraciones de arsénico eran más altas en la época seca y el nivel de riesgo y la carga de enfermedad no eran aceptables.
