Amani H. Ahmed, Nawal M. Suleman

Abstract :

Determination of nine heavy metals(Cr, Ni, Cd, Co, Hg, Zn, As, Pb, and Cu) as pollutants in agricultural soil of ten farms in greenhouse conditions at Zilfi Province –Saudi Arabia, was carried out using ICP–MS (Inductively Coupled Plasma–Mass Spectrometer).The study found that soil samples are not contaminated with five elements :Ni, Co, Hg, Zn, and Cu .The concentrations of the rest elements(Cr, Cd, As, and Pb ) were more than the maximum permitted values of WHO for soils .The maximum concentrations for these elements are as follows: Cr(333.4 gm/kg),Cd( 85 gm/kg), As(38.8 mg/kg) and Pb(160.2 mg/kg).
