Analise dos impactos e potencial de danos da composição e percolação do necrochorume no solo Analysis of the impacts and damage potential of the composition and percolation of the effluent on the soil ABSTRACT Necrochorume is a percolated liquid of reddish orange to grayish color, generated from the decomposition of human bodies, and may present potentially toxic substances depending on its composition. In physical-chemical terms, this effluent is composed of approximately 60% water, 30%

The concern with this liquid is due to the high load of nutrients and pathogens, which permeate and contaminate the soil and water bodies, besides spreading several diseases such as hepatitis "A", typhoid fever, paratyphoid, poliomyelitis, scarlet fever, gangrene and viruses. Depending on the type of soil and the contaminated solution, chemical reactions can alter the concentration of contaminants through the relevant forms of attenuation. Thus, the behavior of the contaminant depends not only on its physicochemical properties, but on the medium in which it is percolating. The contamination resulting from the percolation of the slurry triggers an increase in the electrical conductivity, pH, alkalinity and hardness of the soil solution. Understanding the composition of the leachate is important to predict its behavior in the soil and groundwater, not only by contamination, but also by the interaction that its constituents have in contact with soil and water and with other substances that are present in the soil or from percolation of other waste, which can make these substances much more toxic and intensify the potential contamination.
