潜在有毒元素 (PTEs) 污染了煤矿地区的地表水. (As) 具有显著的致癌风险,特别是对儿童,需要谨慎的水资源管理.
科学领域:
- 环境科学 环境科学
- 地质化学 地质化学
- 公共卫生 公共卫生
背景情况:
- 煤矿区的地表水经常被潜在的有毒元素 (PTEs) 污染.
- 了解PTE的水化学,分布和来源对于评估人类健康风险至关重要.
研究的目的:
- 分析云南-贵州高原地表水中的PTE的水化学特征,空间分布,来源分配和人类健康风险.
- 确定PTE污染的主要来源并评估相关的健康风险.
主要方法:
- 收集和分析了34个地表水样本.
- 对PTE度的统计分析.
- 空间分布分析.空间分布分析.
- 源分配的正矩阵因数分解 (PMF).
- 确定性健康风险评估.
主要成果:
- 检测到Fe,Al,Zn,Mn,Ba,B,Ni,Li,Cd,Mo,Cu,Co,Hg,Se,As,Pb和Sb,其中Fe,Al和Mn集中在特定的河流中.
- 确定了四个主要的PTE来源:煤炭制备厂/矿山废水 (Hg,As,Se),粘土矿物溶解 (Mo,Li,B),煤层矿物溶解 (Cu,Fe,Al,Mn,Co,Ni) 和煤化/运输 (Cd,Zn,Pb).
- 虽然大多数样本显示的非致癌风险低于健康极限,但很大一部分 (73.56%) 由于含量升高而表现出致癌风险,尤其是儿童.
结论:
- 煤炭开采活动是云南-贵州高原地表水中PTE污染的重要来源.
- 具有相当大的致癌风险,需要针对饮用水安全进行有针对性的干预,特别是针对儿童等弱势群体.
- 有效的PTE管理策略对于确保可持续的水环境至关重要.

Sampling Plans
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Sampling Methods: Sample Types
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...
