Introduction

  • Accidental release of petroleum products into the

environment[5]

3

benzene, toluene, ethylbenzene and xylene (BTEX) toxicity of DF Cancer

Introduction

  • Several methods for the remediation of petroleum

contaminated sites[5]

Mechanical (e.g. oil–water separators) Chemical (using chemicals dispersants such as surfactants) Biological (based on bioremediation)
