Contaminação de águas por BTXs e processos utilizados na remediação de sítios contaminados

Abstract

CONTAMINATION OF WATERS BY BTXs AND PROCESSES USED IN THE REMEDIATION OF CONTAMINATED SITES. After decades of polluting actions the environment manifests serious and global consequences. The contamination of soils and groundwater by organic compounds is a widespread problem mainly on account of contamination by leakage from underground storage tanks, which often results in the release of gasoline or other chemicals. The main problem about groundwater contamination is due to the toxicity of water-soluble components such as benzene, toluene and xylene (BTX). In the present work a study about classical and modern methods for remediation of BTX is reported.
