Simultaneous determination of tetrachloro dibenzo-p-dioxin and poly-aromatic chlorinated biphenyls in aqueous environment using liquid phase microextraction

► Method for the determination of chlorinated endocrine disrupting pollutants in wastewater systems was reported. ► The developed method involved sample preparation by liquid phase membrane microextraction. ► The detection was by gas chromatography with electron capture detector. ► The method was able to detect very low amounts of pollutants.
