Presence Of Heavy Metal In Soil On Three Different Sites Of Prayagraj For Forensic Considerations

Abstract

Atomic absorption spectrometry (AAS) is a unique tool for the study of heavy and traces metal components of soil samples. This technique is often utilized for the quantitative determination of elements in environmental materials at trace levels. Heavy metal analysis of soil in forensic science can provide a clue in investigation. Atomic absorption spectrometry (AAS) is a technique through which can measure the amount of trace metals present in soil samples. Variety types of atomizers are in used in AAS most often the flame and the graphite furnace types being utilized in analysis. In field of forensic science heavy metal analysis play a key role as it provide a unique fingerprint of different soil. The present study is conducted to study the correlation between the three different types of land use and the presence of heavy metals in soil. It also highlights the various components of atomic absorption spectrophotometer, different types of AAS in soil examination and applications of atomic absorption spectroscopy in the fields of forensic science.
