Abstract
Soil and plant samples from areas adjacent to Bahr El-Baqar main drain (El-Sharkia Governorate) were collected to study the fate and hazards of some heavy metals, i.e. Pb, Cd, Ni, Zn, Cu, Co …etc. Pollution associated with the studied heavy metals was valued following international norms. The fate and risks of studied pollutants were assessed and appraised using enrichment factor (EF), geo-accumulation index (Igeo), contamination factor (CF), degree of contamination (DC), modified degree of contamination (m Cd), pollution load index (PLI), soil pollution index (SPI). Moreover, the mobility indices and bioaccumulation (BAC) of most hazards selected pollutants were strong-minded in varied plant species grown the in study area including clover, onion, wheat, lettuce and garlic. Meanwhile, correlation analyses between soil properties and heavy metals concentrations in the grown crops were determined. Results showed that the disparity in the properties of sampled soils significantly shaped heavy metals distribution, concentrations as well as speciation. The total contents of Pb, Co, Cd, Ni…etc., exceeded the permissible levels set by Canadian Soil Quality Guidelines (CSQG), European Union Risk Assessment (EU), and the average of the earth crust. Data also exhibited that irrigation with Bahr El-Baqar low quality water is the main source of heavy metals pollutants found in the soils. Other heavy metal might be originated from certain adverse human activities. Regarding the contents of heavy metals found in plants grown in the studied area involving clover, onion, wheat, garlic and lettuce, gained results confirmed that the highest mean value of Cd was detected in all plants, despite other pollutants were also found in the studied  plants, yet at variable concentrations. All indicators calculated in the current work pointed to the worth of reducing pollutants by proper remediation techniques.
