Metal pollution assessment in the surface sediment of Lake Nasser, Egypt

AbstractEight heavy metals were measured seasonally in the sediment of Lake Nasser during 2013. 27 sites were chosen through 9 sectors across the main channel of the lake from Abu-Simbel to Aswan High Dam to assess the levels of the selected metals. The abundance of these metals was in the order of Fe>Mn>Zn>Cr>Ni>Cu>Pb>Cd, with mean concentrations of 12.41mg/g, 279.56, 35.38, 30.79, 27.56, 21.78, 11.21 and 0.183μg/g, respectively. Heavy metals are positively correlated with fine particles (mud fractions) and organic matter accumulation. The results showed perspicuous spatial high significant differences (P<0.01) for all the measured metals. Fe, Cr, Ni, Pb and Cd exhibited temporally high significant differences (P
