Abstract
Purpose
The aim of this study was to evaluate the toxic potential of mining residues by 1) evaluating the concentrations of heavy metals and arsenic in soil and earthworm’s samples from impacted and reference sites in Charcas and Villa de la Paz, San Luis Potosí, México; and 2) evaluating effects by laboratory bioassays and the comet assay in the earthworm Eisenia andrei.
Methods
The quantification of metals in soils was carried out by the Thermo Scientific Niton XL3t Gold Serie 500 environmental analyzer for X-ray fluorescence (XRF), and in the earthworm tissue through ICP-MS. The evaluation of the genotoxic potential of soils was assessed through movility and exposure bioassays with earthworms, determining DNA damage using the comet assay at the end of the bioassays.
Results
In Charcas, the concentrations in soils of heavy metals from highest to lowest were: Pb > Cu > Mn > Cd (Impacted); and Mn > Pb (Reference). In Villa de la Paz, the concentrations were: As > Mn > Cu > Pb (Impacted) and Mn > Pb > As (Reference). The exposure pattern to heavy metals in earthworms in Charcas was: Pb > As (Impacted and Reference); and in Villa de la Paz it was: As > Mn > Pb > Cu > Cd (Impacted), y Pb > As (Reference). In both mining districts, the magnitude of DNA damage in earthworms was: Impacted > Reference > Control.
Conclusion
The results indicate that the impacted soils of both sites represent a significant source of exposure to edaphic organisms, with a notable genotoxic potential.
目的本研究旨在通过以下方法评估采矿残留物的毒性潜力：1）评估墨西哥圣路易斯波托西州查尔卡斯和 Villa de la Paz 受影响地区和参照地区的土壤和蚯蚓样本中重金属和砷的浓度；2）通过实验室生物测定和彗星试验评估对蚯蚓 Eisenia andrei 的影响。方法利用 Thermo Scientific Niton XL3t Gold Serie 500 环境分析仪的 X 射线荧光 (XRF) 对土壤中的金属进行定量，并利用 ICP-MS 对蚯蚓组织中的金属进行定量。对土壤遗传毒性潜力的评估是通过蚯蚓活动性和暴露生物测定进行的，在生物测定结束时使用彗星测定法确定 DNA 损伤情况：铅、铜、锰、镉（受影响）和锰、铅（参考）。在 Villa de la Paz，浓度分别为砷、锰、铜、铅（受影响）和锰、铅、砷（参考）。查尔卡斯的蚯蚓接触重金属的模式为Pb > As（受影响和参考）；而在 Villa de la Paz 则是：As > Mn > As（受影响和参考）：As > Mn > Pb > Cu > Cd（受影响），y Pb > As（参考）。在这两个矿区，蚯蚓的 DNA 损伤程度分别为结果表明，这两个矿区受影响的土壤是环境生物的重要暴露源，具有显著的遗传毒性潜力。
期刊介绍：
The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
