Abstract: This study was carried out to determine and evaluate the concentration of ten heavy metals (As, Cd, Co, Cr, Cu, Fe, Pb, Mn, Ni and Zn) in Hibiscus cannabinus and Moringa oleifera grown at Zango Abattoir, Tudun Wada, Kaduna Metropolis Nigeria, using Atomic Absorption Spectrophotometer. The concentration of the metals obtained ranged from 0.628±0.0006 to 3.469±0.0006 mg/kg for manganese, 8.362±0.0006 to 29.293±0.0026 mg/kg for iron, 0.700±0.0002 to 10.774±0.0026 mg/kg for zinc, 0.071±0.0002 to 0.223±0.0005 mg/kg for copper, 0.020±0.0006 to 0.044±0.0002 mg/kg for nickel, 0.017±0.0001 to 0.039±0.0001 mg/kg for cadmium, ND to 0.184±0.0004 mg/kg for chromium, 1.092±0.0003 to 1.167±0.0006 mg/kg for lead and 0.115±0.0010 to 0.201±0.0016 mg/kg for cobalt. Arsenic was however not detected in all the samples analysed. The concentrations of heavy metals in the selected samples were statistically significant at (P˂0.05). This study highlights that people consuming the vegetables grown within the abattoir consume substantial amount of metals like iron, zinc and lead. However, the values of these metals were below the recommended maximum tolerable guidelines level proposed by the WHO/FAO and NAFDAC.

Abstract: Nowadays the humankind is urgently invited to make available for potable use satisfactory quantities of good quality water to its increasing population. There is a big effort by the water treatment specialists to analyze the solutions the humankind has at its disposition to respond to these risks. The contribution of water reuse (WR) would be great in the humankind’s water tomorrow. This review aims to discuss the growing WR technology as a future solution for water supply issues. WR is broadly applied by industries to decrease the consumption of clean water. WR process should employ treated wastewater mixed with surface water at a certain proportion depending on the degree of purity of the treated water and assuring the dilution effect. WR should not employ at any case only wastewater, for safeguard reasons and psychological effects. WR should be obviously more sophisticated than both water treatment and wastewater treatment since pathogens contamination and chemicals presence can be there most elevated. Since pharmaceutical products and cosmetics substances at trace levels are found in tap water, should we assist to a new formulation of water treatment technology? This will be feasible if water treatment/wastewater treatment/WR would be merged in a super and highly standardized water/wastewater treatment technology, as a future trend.
