Resumen en inglés | Considering the possibility of using the construction and demolition waste (CD) as "chemical barrier" to pollutants in landfill, the influence of the CD in the parameters of the transport of heavy metals in the leachate (leached + rainwater infiltrated) produced by urban solid waste newly collected was investigated. For this, three size fractions of CD (0.5 to 1; 2 to 4 and 4 to 7.5 mm) were used and leachate in the average concentrations of 0.146 mg L-1 for Cu, 0.046 mg L-1 of Cd, 17.2 mg L-1 Zn and 0.135 mg L-1 Pb. The results enabled to conclude that the magnitude of the retardation factors for the metals followed the sequence: Pb>Cu>Zn>Cd; the increase in granulation fractions in BD resulted in smaller retention factor |
