ABSTRACT
Five profiles were selected from Abu –Zaabal area and five
vegetable plants adjacent to soil profiles the profile number one is control
profile and is located North west of the factory The others profile is
located South east of the factory to determine the dangerous pollution
which resulting from involved the study TF,BAF,SEPI and CPI of trace
metals subject of study (Cr, Cu, Zn, Co, and Ni).Soil physical chemical
properties of the studied soil are determined . Soil texture varied from
sand to sandy loam . Soil reaction ranges from neutral to alkaline soil
.The percent of O.M ,CaCO3 and ECe are small values . The cationic and
anionic (me/l ) followed this order SO 4 -- >Ca ++ >HCO 3
- >Mg ++ > Na+
> Cl - > K+> CO 3
-- Total trace. metals contents in the soils . (Zn, Cu, Ni,
Co, and Cr ) were determined by the Ionic Coupled Plasma (ICP), after
digestion of the samples with a ternary acids mixture of HNO3, H2SO4
and HClO4. total trace elements are followed this order Cr >Cu>Zn>
Ni>Co. The values are 118.25, 91.32, 67.95,39.51 and 26.08 mg/kg
receptively. According to the limits of total trace metals, Chromium is
the highest element that is transmitted from soil and accumulate in
vegetable plants and then enters directly or indirectly in food chain
causing public health problems. Chemically extractable of trace metals
contents in the studied soils (Zn, Cu, Ni, Co, and Cr) followed this order
Cu>Cr>Zn>Ni>Co.15.64,15.46,12.40,8.26,and 4.24 mg/kg receptively .
The content of trace metals in grown vegetable plants in the studied soil
followed this order Zn>Cu>Cr>Ni>Co.20.58,43.78,33.24,9.32 and 1.80
mg/kg receptively. All trace metals above the permissible limits except
Co and Ni metals. Given that 1>TF>3 , 1>BAF>3 So occur translocation
from soil to vegetables' and accumulates in them in this order. Onion

between low, moderate and highly contamination.(SEPI ) In all trace
metals varied from low to highly contaminated the soils (1> SEPI )>3).
But in all profiles in the studied soil CPI contamination by multi element except Cu with other metals are
moderately contamination in the surface layer (0 – 30cm ) in the profile
3.where CPI >1 its 1.04 mg/kg.
