Abstract
The highest value of clay content was found in sewage drainage in Damietta zone (73.38) at a depth of (0-15 cm) and (74.23) in agriculture drainage in Damietta at a depth of (15-30 cm). The values of soil pH are ranged from 7.38 to 8.29. The highest value of pH (8.29) and (8.23) was found in agriculture area soil (control) in Damietta at a depth of (0-15 cm) and (15-30 cm), respectively, While the lowest value (7.46) and (7.38) was founded in the soil of Industrial waste sources in Aga at a depth of (0-15 cm) and (15-30 cm) , respectively.When compared concentrations of Nickel at the study sit we show that all concentrations lower content than the permissible limits for element depended on Environmental standards amounting to 50 mg kg-1.The cause of variation between sits due to original content material of this element which recorded a slight variation clearly appeared when S5 But influences and variability observed between treatments due to the natural of element which raised of source and what the contain of heavy metals including Nickel element especially wastewater for industrial process which are raised to irrigation water followed by impact sewage and what accompanied of pollution to irrigation water.The recorded increase in the accumulation index for Nickel element at depth 0-15 cm due to this part more parts vulnerable for pollution and its source and at least influence with depth. There is an indication for incompleteness of pollution by heavy metal with depth. In terms of the effect of the Pollution source under consideration, it was significant in terms of their impact content of this element at 15-30 cm depth as the lowest concentration 1.87 mg cu kg-1 at S5 while the highest 2.05 mg cu kg-1 AS3 As for the cumulative evidence of this element of showed of the table S3 was the most effect and pollution in all sites under study and for depth 0-15 cm within class (3) moderate to severed pollution while was did not polluted to moderate of pollution at treatments S1 ,S4 at sites C and S4 at site B within class (1) except DS3 was within class (2) moderate of pollution.soluble cation Na+ was highest value (8.29) recorded in the water - sample taken from industrial waste area in Talkha. - Soluble cation K+ was highest value (0.64) recorded in the water sample taken from area source with agricultural drainage - in Damietta.For the soluble anions (HCO3-, Cl- and SO4--) all higher values (12.52, 14.02 and 11.05), respectively for anions were recorded water sample taken from car exhaust fumes in Damietta. But the lowest of all values (0.86, 0.78 and 0.07), respectively were found in water sample taken from agriculture area (control) in Damietta. The highest value of soil pH was 9.09 noted in water sample taken from industrial drainage in Damietta while, the lowest value of soil pH was 6.01 noted in agriculture area (control) in Aga.The highest value of N was 6.41 % found in agriculture area (control) in Talkha while, the lowest value of N% was 2.07 %found in area sources industrial drainage in Damietta.The highest value of P% was 0.76% found in agriculture area (control) in Damietta while, the lowest value of P was 0.12 % found in area sources industrial drainage in Damietta.Further studies might be needed especially long term experiments Studies to know the impact of heavy metals accumulation in soil and Water and plant.To reduce the use of wastewater to irrigate soil agriculture and reduced the use daring Water (industrial, sewage and agriculture).Move away from agriculture car exhaust fumes and make long Distance on the highway not to get her pollution and it gather dust.Use recommended doses from organic fertilizers and mineral for its Contribution on reduced the pollution by Heavy metal.Control human activity which increased Heavy metal concentrations in Soil and water and plants which reflex negative on a animals that feed on certain crops of plant then reflection its effect on human.Put filter network for all stations the drainage to prevent increased the Heavy concentrations on soil water and plants .
