Ebrahim Alinia‐Ahandani
Abstract
Increased concentrations of heavy metals in the air, soil, or water threatens human health both directly and indirectly via accumulation in the food chain. In countries with high ecological awareness the risk of acute exposure has been minimized thanks to the enforcement of restoration laws and policies. This paper presents results of chemical analysis of soil samples to total content of Pb, Ni, Cr and Cu. Samples were collected at site of Roodsar, at two depths in November 2019th year. These heavy metals were analyzed using three methods of sample preparation. Method of sample preparation, which defines the standard ISO 11047:2000 proved to be best. Results show that content of these heavy metals exceeding limit values. Analyses were done on device, Atomic Absorption.
