Rapid screening of heavy metals and trace elements in

The accuracy was determined by testing two certified reference soil standards containing major and trace elements and heavy metals. NIST SRM 2710 (Montana soil) basically contained higher amounts of most trace elements (Cu, Zn, Pb, U, Hg, and Mo et c.) than NIST SRM 2711a (Montana II soil) (Figs. 1 and and2). 2). Five to eight replicates were

Lake (AbdelMoati and ElSammak, 1997). On the other hand, Zn and Cu values are within the allowable limits according to USEPA (1986). The high levels of Cd and Pb in water can be attributed to industrial and agricultural discharge (Mason, 2002). The high level of Pb in water of Lake Manzala and Borollus could be attributed to the industrial ().

The soilroot interface fraction has a higher Cd concentration than bulk soil, but the concentrations of Cu and Zn in the soilroot interface fraction are similar to the concentrations in the bulk soil and rhizosphere fractions.
