Application of flat polymer membrane microextraction for the continuous detection of trihalomethanes in aqueous matrices.

A module was developed for the continuous monitoring of volatile halogen organic pollutants in complex matrices. The module utilized a polymer membrane for extraction and a capillary gas chromatography-mass spectrometry (GC-MS) for detection. The extraction of analytes (CHCl(3), CHCl(2)Br, CHClBr(2) and CHBr(3)) from samples was performed in a flow system mediated by a non-porous flat membrane.

Carbamazepine and diclofenac: removal in wastewater treatment plants and occurrence in water bodies.

In the aquatic environment, pharmaceuticals have been widely found. Among them, carbamazepine and diclofenac were detected at the highest frequency. To evaluate the worldwide environmental impacts of both drugs, their global consumption volumes are estimated, based on the dose per capita.
