毕节市煤矿区土壤中砷的环境调查及污染风险预测的研究——土壤中砷元素的原子荧光法测定
Research on Environmental Investigation and Pollution Risk Prediction of Arsenic in Soil of Bijie City Coal Mining Area—Determination of Arsenic in Soil by Atomic Fluorescence Spectrometry

本研究采用原子荧光光谱技术对毕节市煤矿区周边土壤中的砷元素含量进行定量分析，探讨煤炭中砷元素可能对人体健康造成的风险。基于环境中砷元素的污染浓度，进一步建立了土壤砷的标准曲线，为定量分析和环境风险评价提供科学依据。实验数据分析表明，研究区域土壤中砷元素含量虽处于较高水平，但仍低于国家土壤环境质量标准中的风险阈值。这一发现提示，该地区应制定科学合理的土壤管理策略，采取必要的防控措施以保障土壤资源的可持续利用。
This study utilizes atomic fluorescence spectroscopy to quantitatively analyze the arsenic content in the soil surrounding the coal mining areas of Bijie City, investigating the potential health risks posed by arsenic in coal to human health. Based on the contamination levels of arsenic in the environment, a standard curve for soil arsenic was established to provide a scientific basis for quantitative analysis and environmental risk assessment. Analysis of the experimental data indicates that although the arsenic content in the soil of the study area is relatively high, it remains below the risk threshold specified in the national soil environmental quality standards. This finding suggests that the region should develop scientifically sound soil management strategies and implement necessary preventive measures to ensure the sustainable utilization of soil resources.
