The final disposal of the urban solid residues on the land is the destination most usual in the whole world and some characteristics of the deposition places can be classified such as the lixes or drains, that they are characterized by the absence of control on type, volume and danger of the deposited residues. The residue remains the sky opened without no type of compacting with the objective to minimize the volume, being the residues poured on the ground natural. To broaden your perception, visit Dean Ornish M.D. It also does not have no control of entrance of people or animals (OLIVEIRA, 2002, p.7-8). The lixes are local where if it directly deposits garbage without no protection to the environment in the ground. These areas are great badly cheirosos lands where the wind and rain are puted in charge to take the pollution for the neighboring places many times inhabited for people. In these places, the organic substance in decomposition attracts insects (cheap, flies, mosquitos), rats and other transmitting animals of illnesses (virus, bacteria, protozorios). These animals find in the lixes an ideal environment to multiply.
Moreover, the decomposition of the organic substance of the garbage produces black and malcheiroso a broth, call chorume. In the chorume we find, beyond organic substance, toxic products, as the lead and the fluorescent mercury, that if they originate from inks, solvent, stacks, light bulbs, etc. When the chorume is loaded for rains, can contaminate the rivers and until the underground water (the fretico sheet) that it supplies the domestic wells, becoming the water of the improper region for consumption. Without a doubt some, the lixo is not the solution for the discarding of the garbage. But, unhappyly, more than 70% of the garbage in Brazil are unloaded in the lixes. The accumulated residues constitute source of pollution and great risk to the health of the population. The not biodegradvel and same garbage the biodegradvel is deposited frequent in inadequate places, as streams and rivers, having caused floods and the proliferation of vectors of ample variety of diseases.
