Moringa oleifera has several applications in the food, feed, and supplement industries. Urban water contamination poses a risk to our food supply. Heavy metals (HM) such as Cd, Ni, Al, Cr, Pb etc. are toxic substances that have a negative impact on plant growth and are often found in urban wastewater. Seedlings of two Moringa strains: "Faisalabad white" (M1); "Original PKM1" (M2) grown (in the Department of Agronomy at the University of Agriculture in Faisalabad (UAF), Pakistan) in earthen pots (for six months) were monitored to assess the impact of Cr and Pb when treated with two different dosages of each metal [Cr, 0.2 mg L-1 (T1) and 0.4 mg L-1(T2); Pb, 10 mg L-1 (T3) and 20 mg L-1 (T4)]. Results revealed that metal (Cr and/or Pb) added water resulted in decreased the survival rate, growth and fresh and dry biomass in M1 and M2 seedlings under greenhouse conditions. However, higher concentration of HMs significantly enhanced metal contents in root, stem and leaves portion of both cultivars. It was noticed that Pb was more toxic as all the studied attributes had reduced values as compared to Cr. The decreasing pattern in terms of growth for both moringa types was M1 > M2 and for the metal treatments T0 > T1 > T2 > T3 > T4 during study period while, for the Cr contents was T2 > T1 > T0 and for Pb contents in various plant parts was T4 > T3 > T0. Data revealed that different levels of Cr and Pb strongly affected growth, biomass, and metals absorption characteristics of moringa. Furthermore, the ability of the used moringa types to take up Cr and Pb varied accordingly and low levels Cr and Pb contents were noted in Moringa M1 (local). This suggests to use this plant in advanced moringa breeding programmers for better moringa production.
