Influencia de la edad de lixiviados sobre su composición físico-química y su potencial de toxicidad

Abstract

Leachates are byproducts of the normal operation of landfills that may contain a huge diversity of contaminants; traditional landfills management practices are mainly based on physicochemical characterization due to their relationship with toxicity. The aim of this study was to analyze the influence of age leachates of cells from two different landfills and one weir on physicochemical characteristics and their toxicity potential. In general, we observed that the composition of the leachates depends of the age of the cells in which they’re originated, finding greater concentrations in younger leachates in which the majority of measures are associated with organic matter and solid variables, in the older leachates, the measured concentrations and the relationship between the variables decreases, being necessary to characterize a greater number of variables
