The study focuses on the impact of heavy metal concentrations and sediment toxicity in the Cauvery and Vettar estuaries on the East coast of India, which are affected by industrialization, urbanization, and agricultural activities.
Core sediment samples show that Cauvery has more sand while Vettar has a higher clay content with increased organic matter due to waste disposal.
Analysis reveals a decreasing order of heavy metals (Fe, Zn, Ni, Pb, Cu, Cr) and indicates significant pollution levels, posing ecological risks and affecting biodiversity and human health in these estuarine regions.
