概括
在Citarum河的重金属污染是一个重大问题,河水和地下水显示高水平的潜在有毒元素 (PTEs). 地下水中的高含量对当地居民构成重大癌症风险.
科学领域:
- 环境科学 环境科学
- 环境化学环境化学
- 生态毒理学 生态毒理学
背景情况:
- 奇塔鲁姆流域是西爪省的一个关键水资源.
- 对有害化合物的定期监测对于环境保护至关重要.
研究的目的:
- 评估Citarum河上游流域潜在有毒元素 (PTEs) 的污染水平.
- 评估与水,沉积物,地下水和土壤中PTE污染相关的生态和健康风险.
主要方法:
- 在河水,沉积物,地下水和土壤中分析PTE度 (Cd, Pb, Mn, Fe, Cu, Cr, Hg).
- 计算污染指数,如重污染指数 (HPI),地球积累指数 (I-geo),污染因子 (CF),污染负荷指数 (PLI) 和平均ERM-Q.
- 使用危险系数 (HQ) 评估生态风险,使用总危险指数 (THI) 和瘤致癌风险 (TCR) 评估人类健康风险.
主要成果:
- 河水和地下水呈现出高水平的PTE污染 (HPI:分别为14,733和933).
- 根据I-geo,CF,PLI和M-ERM-Q值,沉积物和土壤显示低污染水平和生态风险.
- 河水中的PTE对水生生物构成风险 (HQ > 1),而地下水和土壤污染对人口构成致癌风险 (TCR > 1E-04).
结论:
- 地下水和河水受到PTE的严重污染,造成生态和人类健康风险.
- 地下水中的度是癌症风险的主要驱动因素,在灵敏度分析中贡献了99.9%.
- 降低地下水中的含量至关重要,以减轻Citarum河上游地区人口的癌症风险.

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
47
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
