“…This trend was consistent with that in the atmospheric emissions of Pb from 2002 to 2012, which also indicates that atmospheric Pb emissions were a significant source of soil Pb. According to the report by Shi et al [ 33 ], Pb concentration peaked in 2006–2010, and a decrease was observed during 2011–2016, which was consistent with the results of this paper. Recently, the Chinese government adopted a series of measures to cut off the source of pollution, speed up the remediation process, and avoid further pollution, especially the 12th Five Year Plan for the control and abatement of heavy metals, which was implemented from 2011.…”

The contamination of soil by lead (Pb) is a serious and widespread problem in China, especially in mining areas. This paper summarized the available data regarding Pb-contaminated soils around various metal mines in China. Based on these data, the Pb concentration in the soil and its temporal and spatial changes were analyzed. Potential ecological hazards and adult lead models were also used to estimate ecological and health risks. The results indicated that the concentration of Pb was closely related with the type of mine. Compared with other types of mine, soil around lead-zinc (Pb-Zn) and tin (Sn) mines with high Pb contents in the metallic ores and high pollutant emission coefficient were more strongly polluted by Pb. The characteristic spatial and temporal variations of Pb pollution status in China were clarified, and the results showed that the concentration was high in the southern, southwestern, and central regions of China where many mining areas were located, and the mean value passed a turning point in 2012. Ecological risk assessments indicated that some areas around mines were at considerable to high risk, and the risk was relatively severe in Pb-Zn mining areas. According to the adult lead model, Pb-Zn mines had a greater impact on blood Pb concentration than the other types of mine.

“…The current result is well above the mean Pb content of the world's soils (25 mg / kg) (Kabata-Pendias & Mukherjee, 2007) and it seems likely that Pb in the soils of the Peruvian Andes, close to mining-metallurgical activities, is at the upper end on a global scale, as reported in several studies (Salman et al, 2019 WoS;Shi et al, 2019;Osobamiro & Adewuyi, 2015;Santos-Francés et al, 2017;Castro-Bedriñana, Chirinos-Peinado, Peñaloza-Fernández, 2020).…”

Lead (Pb) is highly toxic heavy metal that is detrimental to the food system. There are large mining and metallurgical companies in the central highlands of Peru that have been active for almost a century and contribute to air, water, and soil pollution, affecting food quality and causing damage to the environment and human health. Our study, conducted in 2018, assessed the content and transfer of lead in the soil-root-plant system in the high Andean grasslands in a geographical area near the metallurgical complex of La Oroya. Lead levels were measured in 120 samples of top soil (0–20 cm), roots, and grass shoots by flame atomic absorption spectroscopy. No significant differences were found between the soil pH, organic matter content, and lead among the samples evaluated (P > 0.05). Mean Pb concentrations decreased in the order of soil > root > shoot (P < 0.01) (212.36 ± 38.40, 154.65 ± 52.85 and 19.71 ± 2.81 mg/kg, respectively). The soil-to-root Pb bioconcentration factor, root-to-shoot translocation factor, and soil-to-shoot bioaccumulation factor values were 0.74 ± 0.26, 0.14 ± 0.06 and 0.10 ± 0.03, respectively. Lead in the soil was 3.03 times higher than the maximum limit for agricultural soil, and was 1.97 times higher than the value limit for fodder. Our findings are important and show that soils and pasture in this geographical area have high Pb levels due to metallurgical emissions that have been occurring since 1922. Such pollution negatively impacts health and the socio-economic status of the exposed populations.
