520 |b Pot experiment were carried out under open field conditions, Libya; to investigate the effect on dry matter yield and heavy metals content in alfalfa plants cultivated on sandy and loamy sand soils treated with sewage sludge and irrigated by sewage effluents and to investigate also the heavy metals uptake and de-pollution of metals from soils. Results showed that sewage utilization improved some physicochemical parameters of soils. Higher dry weight yields were given by alfalfa plants in shoots than roots. Copper, chromium and lead were the most accumulative element, nevertheless copper still superior. Heavy metals level in alfalfa plant revealed the following trend, Cu > Cr > Pb > Co > Cd; using primary treated effluent and final effluent for irrigation. Sludge addition rate of 50 t/ha reflected higher metals contents than 25 t/ha. Copper more uptaken than chromium, lead, cobalt and cadmium; heavy metals were more absorbed as they irrigated by raw influent followed by primary treated and final effluent. Depollution efficiency results showed that alfalfa was hyper¬accumulator plant; where chromium and lead were the most de-polluted elements, higher using raw influent than primary treated and final effluent, higher metals were up-taken using the rate of 50 t/ha than 25 t/ha.
