Abstract

The current work was carried out at Kafr EI-Sheikh Governorate during 2007/2005 season to investigate the effect of using three water quality; Nile water (Abou-Omar. W1), mixed Nile and polluted drainage water (EI-Bana, W2) and polluted drainage water (Kafr Dokhmeis, W3) in irrigation of agricultural land on accumulation of some heavy metals in clay soil and berseem grown thereon and subsequently in milk of cows and buffaloes fed on this berseem. Results showed that W3 recorded significantly (P<0.05) the highest electrical conductivity (EC) value, cations (Ca2++. Mg2++. Na+ and K+) and anions (Hco3. Cl- and So4 concentrations followed by W2, while W1 had the lowest values, Moreover. soil irrigated with W3 recorded significantly (P<0.05) the highest EC, cations and anions concentrations followed by this irrigated with W2, but this irrigated with W1 had the lowest values. Polluted drainage water (W3) recorded significantly (P<0.05) the highest concentrations of heavy metals (Mn, Cu. Pb, Cd and Ni) followed by W2, while W1 had the lowest concentrations. Moreover. soil irrigated with W3 recorded significantly (P<0.05) the highest contents of Mn. Cu, Pb. Cd and Ni followed by soil; irrigated with W , while soil irrigated with W1 had the lowest contents. Berseem samples grown in soil irrigated with W3 showed significantly (P<0.05) the highest heavy metals contents followed by berseem grown in soil irrigated with W2, while berseem grown in soil irrigated with W1 had the lowest contents. The highest contents of Mn, Cu. Pb, Cd and Ni in milk of cows and buffaloes were found with feeding berseem grown in soil irrigated with W3 following with feeding berseem grown in soil irrigated with W2, but the lowest content noticed with feeding berseem grown in soil irrigated with WI (P<0.05). It could be concluded that using polluted drainage water alone or mixed with Nile water in irrigation of agricultural land led to increasing the accumulation of heavy metals in clay soil, berseem and milk of cows and buffaloes causing possible hazardous effect in animal and human health. Keywords: polluted drainage water, heavy metals, soil, berseem, cows and buffaloes milk.
