Abstract

To assess the extent of the contamination of human activities on irrigation water of El-Zomor canal on soil and grown crop, soil, water, sediment and plant samples were taken from El-Zomor area during the growing season (2011-2012). Results showed that the measured trace elements as well as COD & BOD are below the permissible limit. While, the pathogenic indicators exceeded the permissible limits in water and sediments according to the Recommended Maximum limits. According to the calculated ratio EF; sediment mud samples are contaminated with Cd followed by Pb and Co. Ni & Cd were not found along El-Zomor canal. Soil samples are contaminated with Cd & Ni while the rest are within the normal range. BCR of plant tissues are showed a specified capability to accumulate Fe, Mn, Co in cauliflower tissue ; Zn, Cd are accumulated in  clover shoot and  ( Cr & Ni)  are accumulated in  wheat shoot.
Public awarance and control bad human activities at the relevant state agencies are necessary.
