  ABSTRACT: We aimed to find the toxicological impacts of Cd, Pb and Zn in single dozes and in combinations on Purslane (Portulaca oleracea) seedling. The Pursolane seedlings grown in pots in a green house were treated with different soil treatments spiked (mg/kg) with Pb (300, 400 and 500), Cd (0.5, 1 and 1.5), and Zn (250, 500, 700) alone and then in specified combinations/concentrations i.e., Cd/Pb (0.5/300, 1/400, 1.5/500), Cd/Zn (0.5/250, 1/500, 1.5/700) and Pb/Zn (300/250, 400/500, 500/ 700). The results indicated that increasing concentrations of the studied HMs in seedlings tissues significantly (p P. oleracea seedling, compared to Pb and Zn. Roots of P. oleracea seedlings were more sensitive to the studied HMs in comparison with shoot. The uptake patterns showed antagonistic impacts on each other and were reflected in response to growth parameters. The combine toxicities of Cd, Pb and Zn (Cd/Pb, Cd/Zn and Pb/Zn) were more than the toxicity due to single dose of each element but less than their additive sums.
