Heavy metals accumulation by Vicia faba L and Pisum sativum L plants grown in contaminated soil

Abstract

This study was conducted in agricultural fields near the city of Al-Marj. Al- Marj area is located on the southern coast of the Mediterranean Sea in the province of Cyrenaica . Many vegetables and fruits grow in these agricultural fields, and the domestic and industrial wastewater streams pass through them, and the study aimed to determine the quantity of heavy metals( Cd ,Ni, and Pb) in leguminous plants beans( Vicia faba L) and peas (Pisum sativum L) growing in soil contaminated with domestic and industrial wastewater. All the experiments were conducted at the Al-Bariqa company laboratory in Tripoli, Libya. Samples of some grown vegetables, i.e.,beans( Vicia faba L ) and peas (Pisum sativum L),were collected from seven different locations in the agricultural fields. For metal analysis, only the pods of in two studied plants samples were used, Three replicates were taken from plant samples. The study results showed that pods of studied plants in different locations contained heavy metals with different concentrations within the normal levels of toxicity except cadmium .the concentration of cadmium was over then (0.1)ppm., which was applied by (WHO)
