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.

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.
