Evaluation Of Environmental Contamination By Persistent Organic Pollutants Utilizing Simulation Of Leach Processes [avaliação De Contaminação Ambiental Causada Por Poluentes Orgânicos Persistentes Utilizando Simulação Computacional]

Abstract

Environmental concern is growing in the current days and there is global agreement to banish production and use of persistent organic pollutants (POP). The synthetic insecticides chlordecone and mirex, classified as POPs, have similar structures and they are potentially toxic. This work uses properties and physicochemical constants related to the pesticides and computational simulation to evaluate the leach phenomenon and persistency in soil. The largest tendency of persistence of the compound is found to be in the surface of soil, but even low concentration in water represents a high risk due to bioaccumulation in adipose tissue.303565568http://www.atsdr.cdc.gov/toxprofiles/tp66.html, acessada em Julho 2005http://www.lrrb.org, acessada em Agosto 2005Miyamoto, J., (1996) Pure Appl.
