(a) Effect of solid : liquid ratio (1 : 10 and 1 : 50). (b) Effect of pH (3, 6, and 9). Solid : liquid ratio 1 : 10, 0.01 M NaNO3,  h. (c) Effect of P and time (24 and 240 h). The grey dashed and the solid black lines indicate the leaching limit values for waste acceptable in landfills for inert and nonhazardous waste, respectively (EC 2003).
