Abstract

This research verified the influence of a Sanitary Landfill located at the Jockey Club of the Brasilia City (JCB) on the chemical contents in the tree species of “Cerrado”. Six 25 x 500 m blocks were established in the PNB to sample the soil and the trees to chemical analysis. Three blocks were established near the landfill area and three in the control area. Nitrogen, phosphorus, potassium, calcium, lead, chromium, copper and mercury were analyzed. The highest nutrients and metals concentrations in soil were sampled in landfill adjacent area. The significant, crescent and directly proportional relationship (R2 > 0.80; p < 0.001) were observed between the elements concentration analyzed in soil with the leaves tissues. Therefore, the studied landfill presences increased nutrients and metals concentrations in soil and leaf tissue, fact that did not occur in the control area.
