Chemistry of organic traces in air VI: distribution of chlorinated C/sub 1/ - C/sub 4/ hydrocarbons in air over the northern and southern Atlantic Ocean
Air-samples were collected on board of the German research vessel F.S POLARSTERN on its cruise from Capetown to Bremerhaven by adsorption on Tenax TA. Additional samples were collected on the Azores (6/82), on Madeira (3/84, 8/84) and on the Bermuda Islands (7/85). They were analyzed by high-resolution gas chromatography with electron-capture detection (HRGC-ECD). Tetrachloromethane (CCl/sub 4/) is taken as a stable internal standard in tropospheric air for the characterization of anthropogenic organohalogen trace gases such as CHCl/sub 3/, CH/sub 2/Cl-CH/sub 2/Cl, CH/sub 3/-CCl/sub 3/, CHCl=CCl/sub 2/, CCl/sub 2/=CCl/sub 2/ and minor constituents such as CH/sub 2/Cl-CCl/sub 3/, CHCl/sub 2/-CHCl/sub 2/, CHCl/sub 2/-CCl/sub 3/, CCl/sub 3/-CCl/sub 3/ and CCl/sub 2/=CCl-CCl=CCl/sub 2/. Latitudinal distributions over the Atlantic Ocean and differences between distinct air masses with different origins are shown. With the concept of a normalized patterns analysis it is possible to characterize sources, transport and degradation processes on a global scale.
