Description
Summary:The procedure used for the anal. of samples of Antarctic surface fresh water taken during the 1988-89 Italian Expedition is reported. After solvent extn., samples were examd. to evaluate the presence of some chlorinated pesticides by gasw chromatog. (GC) with (electron capture detector) and GC-mass spectrometry (MS). Many small peaks with retention times in the PCB and chlorinated pesticides range were obsd. by GC-electron capture detection; none of the obsd. peaks among the ones of the searched chlorinated pesticides was identified by SIM-GC-MS. The detection limit of 8 chlorinated pestici.
