A review: Analytical methods for heavy metals determination in environment and human samples

A Review: Analytical methods for heavy metals determination in environment and human samples Many different techniques have been applied for determination of heavy metal in different samples.Atomic absorption spectrometry (AAS) is a quantitative method of metals analysis which was suitable for the determination of 70 elements by three option accessory (flame, furnace, Hydride generation).AAS measures the concentration of the metals by passing light (wave length emitted) by a radiation source of
