Abstract

The current study investigated the distribution and health risk assessment of heavy metals present in the sediment samples Cauvery River. During the monsoon season, the sediment samples were collected at 13 sampling sites along the Cauvery River. The findings of the present study revealed elevated concentrations of metals, including Cr, Zn, Cu, Co, Pb, As, Cd, and Hg. A robust statistical relationship was identified among the sampling locations of all the elements under analysis (P < 0.05). Moreover, investigations into the pollution load index and geo-accumulation index revealed that the distribution of heavy metals during the monsoon flood had moderate to higher effects. However, it can be observed from the average values of PER (720) and PLI (> 1) that the sediments of the Cauvery River possess a considerably high level of toxicity. Based on the results, the sediment samples from the Cauvery River basin exhibited significant levels of Cd and Hg, whereas other metals were comparatively less severe.

季风洪水对印度泰米尔纳德邦Cauvery河表层沉积物中微量金属空间分布的影响

本研究调查了高韦里河沉积物样品中重金属的分布及健康风险评价。在季风季节，在高韦里河沿岸的13个采样点采集了沉积物样本。本研究的结果显示，包括Cr、Zn、Cu、Co、Pb、As、Cd和Hg在内的金属浓度升高。在所分析的所有元素的采样位置之间确定了强有力的统计关系（P < 0.05）。此外，对污染负荷指数和地质累积指数的调查表明，季风洪水期间重金属的分布具有中等至较高的影响。然而，从PER（720）和PLI （> 1）的平均值可以看出，高韦里河的沉积物具有相当高的毒性。结果表明，高韦里河流域沉积物样品中Cd和Hg含量显著，而其他金属含量相对较轻。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
