BEHAVIOUR OF LEAD ION IN DOMESTIC LANDFILL
2007
Claudia Lucia de Moura | Raphael Hypólito
This work was performed in an area with three domestic landfills where the groundwater, sedimentsand soil are seriously contaminated due to the ions of lead, most likely because of the landfill. In some sampling points,results from chemical analysis of groundwater were four times greater than the criteria established by environmentalagencies. The soil, due to its unfavorable capability to hold lead, is other risk factor to environmental disturbance in thearea. Analysis by Diffraction of X ray showed the tendency of caulinite and gibbsite, which combined with a low valor ofionized change capacity and organic matter, makes the soil not able to absorbed metal ion. On the other hands, to all thesefactors is added the human activities in the neighborhood. The population uses water from a shallow drinking well andbesides there is also farming and vegetable grown in the surroundings.
