Analytical techniques for the determination and measurement data of 7 chlorinated C-1- and C-2-hydrocarbons and 6 monocyclic aromatic hydrocarbons in remote air masses: An overview

This overview is focusing on methods for the sampling and analysis of seven chlorinated C-1- and C-2-hydrocarbons and six monocyclic aromatic hydrocarbons at marine and remote continental sites and in the free troposphere. Results obtained by analysing field samples with the methods described are reported as well. According to the literature samples are taken in sample loops, by adsorption on solid matrices, by condensation in cold traps (cryogenic sampling) or whole air samples are taken in canisters. The performance of different sampling and preconcentration techniques is compared. Details on the analyses in sensu strictu (methods of injection, separation and detection) are given. Attention is paid to data on limits of detection, reproducibility and calibration. Finally, measurement results of these compounds at coastal, bay, estuarine, island, remote continental and open sea locations and in the free troposphere are presented. (C) 1997 Elsevier Science Ltd.
