Abstract

The aim of the study was to determine the effects of physicochemical properties of sediment samples on the heavy metal, magnetic susceptibility, and natural radioactivity concentration. Spectroscopic techniques like energy-dispersive X-ray fluorescence, dual-frequency susceptibility meter, and gamma ray spectrometry measurements are commonly employed for the determination of heavy metals, magnetic particle, and radioactivity concentration in sediment sample collected from Pulicat Lake to Vadanemmeli, of Chennai Coast, Tamilnadu. The relations between the physical and chemical properties and studied parameters of sediment samples were mainly clarified with Pearson correlation, factor, and cluster analysis. Silt content was the most effective parameter on the studied parameter. The results are discussed and the conclusion is drawn.

Highlights

Grain size analysis is the most basic property used by geologists to study transport phenomenon such as transport and deposit of sediments
From the cluster analysis result, it can be said that there is a strong correlation between radionuclides and physicochemical pair, which is a good agreement with factor, but cluster analysis results did not show a good agreement between K and physicochemical properties pair
The obtained results of magnetic parameters with the physicochemical parameters in sediments showed that its value decreases in grain size

Summary

Introduction

Grain size analysis is the most basic property used by geologists to study transport phenomenon such as transport and deposit of sediments. This property helps the ecologists in the study of habitats and engineers in the study of permeability. Geochemists use this property extensively to study kinetic reactions and hydrologists use it to study subsurface fluid flow (Blatt et al 1972; McCave and Syvitski 1991). Sediment texture indicates the characteristics of soil such as clay, silt, and proportion of sand.
