Co > Ni > Cr > Cu > Pb > Zn > Fe, suggesting that soil samples were extremely enriched with Cd, while Pb exhibit significant enrichment. Geoaccumulation index showed that the soils of Bahr El-Bakr were uncontaminated with Fe, Zn, Cu, Ni, Co and Cr and moderately contaminated with Pb but Cd followed strongly/ extremely contaminated index. It was also observed an elevation in nitrate contents in the edible parts of the collected leafy vegetables. Heavy metal concentrations in leaves, cereal, fruits tubers of edible parts of plants and shoots of clover plants decreased in the order; Fe > Al > Zn > Cu > Mn >B >Ni >Cr > Pb >Ba >V >Mo >Co >Cd, with increase of toxic metals such as Al, Cr, Pb, Ni and Cd concentrations that were higher than the permissible limits.These results indicated that long term irrigation with waste water from Bahr El-Bakr drain had a negative impact on both chemical and microbiological quality of soil and plants in this region.]]>
