Physical-chemical characterization of the land of the Portoviejo dump and analysis of the spatial distribution of chromium (VI), nickel, bromine and iron

Abstract:

The open dump in the city of Portoviejo is in the technical closure stage and there are domestic and industrial waste. These wastes can generate contamination by the various toxic chemical elements they contain. The objective of this work was to characterize soils through physical and chemical parameters such as pH, humidity, electrical conductivity, Dry Evaporated Residue (RSE), Calcined Dry Residue (RSC), real and apparent density and measure Cr (VI), Ni, Br and Fe for proposing a zoning of possible spread of contaminants, in relation to leaching curves. We proceeded to analyse several sampling techniques, in terms of feasibility and applicability to the study area, so was used methodology proposed by the Ecuadorian Environmental Technical Standard, the Secretariat of the Environment of Mexico and the proposal based on the publication of Research of the Soil Pollution of the Basque Government of …
