## Abstract This paper describes two highly sensitive analytical methods for the unambiguous determination of pharmaceutical residues and related polar contaminants in environmental water samples. Both analytical methods use solid phase extraction (SPE), chemical derivatization, and detection of th

## Abstract Using Hβatoms produced in the radiolysis of water vapour, we determined the kinetic isotope effect for the reaction where RH and Rβ²D are methylcyclohexane and perdeuterated methylcyclohexane, respectively. The result obtained from the isotope competitive method can be expressed with th
The monitoring of air pollution requires simple, rapid and sensitive sampling and analytical techniques with minimal sample manipulation that are usable for routine analyses. In our laboratories we have developed a method for the analysis of air samples collected by adsorbent cartridges based on sol
