“…The lead, cadmium, copper, and zinc concentrations in these samples decreased markedly with increasing distance from the zinc smelter in the Wumeng mountain area. This tendency has been observed in other studies of heavy metal contamination in areas surrounding smelting industries [21] and indicates the aeolian dispersion of particles containing heavy metals (lead, cadmium, copper, and zinc) from these smelters are a source of heavy metal contamination in soils [22–23]. Waste water discharged from the zinc smelter has been used to irrigate surrounding pastures and farmland in the Wumeng mountain area and was therefore also a source of heavy metals (cadmium, lead, copper, and zinc) in the agricultural soils of the study area.…”

15A diagnosis of heavy metal poisoning in sheep living on pasture in the vicinity of a zinc smelter 16 was made based on laboratory tests and clinical signs in livestock in the Wumeng mountain area 17 of China. Heavy metal contamination has generated serious harm to the health of local farmers 18 after passing through the food chain. The levels of copper, zinc, cadmium, and lead in irrigation 19 water, soil, forages, and animal tissues were measured in samples taken from within the vicinity of 20 a zinc smelter and control samples. Heavy metal concentrations in foods (corn, rice, and wheat) 21 and human tissues (blood and hair) from local farmers living in affected areas and controls were 22 also determined. Hematological values were determined in human and animal samples. The 23 copper, zinc, cadmium, and lead concentrations in irrigation water, soils, and forages were 24 markedly higher than the levels in healthy pastures. Cadmium and lead concentrations were 25 177.82 and 16.61 times greater in forages than controls, respectively, and 68.71 and 15.66 times 26 greater in soils than controls, respectively. Heavy metal concentrations in food (corn, rice, and 27 wheat) in affected areas were markedly higher than in the control samples. Cadmium and lead 28 concentrations in the tissues of affected sheep were markedly higher than in control animals (P < 29 0.01). Cadmium and lead concentrations in blood and hair samples from affected farmers were 30 markedly higher than the control samples (P < 0.01). The occurrence of anemia in affected 31 persons and animals followed a hypochromic and microcytic pattern. The intake of cadmium and 32 lead was estimated according to herbage ingestion rates. It was found that the levels of cadmium 33 and lead accumulated in sheep through the ingestion of vegetation growing in the sites closest to 34 the zinc smelter were approximately 3.36 mg Cd/kg body wt./day and 38.47 mg Pb/kg body 35 wt./day. This surpassed the fatal dosages for sheep of 1.13 mg Cd/kg body wt/day and 4.42 mg 36 Pb/kg body wt./day. Serum total antioxidant capacity in affected humans and animals was 37 significantly lower than in the controls (P < 0.01). The serum protein parameters in affected 38 humans and animals were significantly reduced (P < 0.01). It was therefore concluded that heavy 39 metal contamination has caused serious harm to sheep in this area. The heavy metal 40 concentrations in food and grain also pose a significant risk to human health in the Chinese 41 Wumeng mountain area. 65 China. The area has extensive heavy metal reserves, characterized by large quantities of ores 66 containing zinc, copper, and lead [2]. A large number of industrial enterprises were established for 67 the purpose of lead, zinc, copper, and polymetallic extraction in the 2010s. After a few years of 68 intensive development, metallurgical industries occupied a very wide area of former pasture and 69 farmland [1]. A number of sheep grazing on pastures in the vicinity died after the smelters went 70 into operation. All of the...

“…The ZGH ''Bolesław'' activities entailed underground ore mining in the ''Bolesław' ' (closed in 1998), ''Olkusz'' (closed in 2003), and ''Pomorzany'' (still active) mines. Environmental problems became aggravated in the area due to secondary dusting from unprotected disposal sites, dumps, and settlements, contaminating the atmosphere with particulates carrying significant amounts of heavy metals (Kicki 1997;Sroczyński 1997;Danek 2007;SzarekŁukaszewska and Grodzińska 2011;Kapusta and Sobczyk 2015). Additional problems were generated by pollutant re-emission from uncovered bedrock (Dmuchowski et al 2011).…”

Long-term changes of As, Cd, Fe, Pb, Tl, Zn, Cl -, SO 4 2-, and PO 4 2-contents were calculated in topsoil samples and soil profiles in the vicinity of the Zn-Pb mine and processing plant at Bukowno, Poland. Evaluations were based on research results obtained in 1994-2014. Soil was described on the basis of hand specimens for which the following were determined: active and potential pH, organic matter content, moisture content, buffer properties, total metal content (HCl?HNO 3 3:1), forms of binding metals (using the BCR sequential extraction procedure), metal bioavailability (extraction by the 0.05 M EDTA solution), and water leaching of metals. Soil contamination was determined by the contamination factor and the pollution load index. The potential environmental risk was determined by the risk assessment code (RAC). Twenty-year-long research demonstrated the trend of decreasing metal content in topsoil. The sampling sites, selected in close vicinity of the flotation tailings dump, showed increasing contents of As, Pb, and Cd. The metal content in soil profiles revealed a significant decrease with time. Metal bioavailability, tested in all soil samples, indicated that the exchangeable forms were carriers of mainly Cd (up to 83%), Zn (up to 72%), and Pb (up to 60%) (the proportions refer to total metal contents), whereas As, Fe, and Tl were bound either with hardly movable forms or remained in the extraction residuum. The RAC showed medium to high environmental risks in soils, caused by the presence of Cd, Zn, Pb, and Tl.

“…Dentro de las actividades que alteran la composición del suelo está la minería, que causa el aumento de daños visibles al suelo mediante la creación de minas a cielo abierto, escombreras, estanques de residuos y otras instalaciones de minas. El esfuerzo principal de las investigaciones está dirigido a desarrollar métodos apropiados de gestión de dichos sitios después de su abandono para neutralizar los efectos potencialmente adversos sobre el ambiente local [2].…”

<p>Dentro de las actividades que alteran la composición del suelo está la minería, que causa el aumento de daños visibles al suelo mediante la creación de minas a cielo abierto, escombreras, estanques de residuos y otras instalaciones de minas. El objetivo principal de este trabajo fue evaluar el efecto de la lombriz roja californiana sobre el crecimiento de microorganismos en suelos contaminados con mercurio en el municipio de Segovia, Antioquia. Estos suelos representan una problemática importante debido a la acumulación de mercurio en exceso que ocasiona la pérdida de la calidad del suelo. Para este estudio se tomaron cuatro tratamientos en diferentes concentraciones de mercurio y un tratamiento más como blanco con lombrices rojas californianas <em>(Eisenia foetida). </em>Para esto, se evaluó el crecimiento de microorganismos a través de diferentes cultivos en el laboratorio, encontrando un crecimiento satisfactorio de los mismos luego de 25 y 90 días de tratamiento. De acuerdo al comportamiento observado, se evidencia una inmovilización del mercurio y una adaptación de los microorganismos al suelo contaminado, mostrando un aumento significativo de estos con el transcurso del tiempo.</p>
