摘要

Trace pollutants in the surface water of the Arctic region have been analyzed by the capillary gas chro-matography with the micro-electron capture detector (GC-μECD), the gas chromatography-mass spectrometry (GC-MS) and the inductively coupled plasmas-mass spectrometry (ICP-MS). Compared with previously reported studies, concentrations of OCPs in these regions are much lower than those in the last decades. The ratio of α-/γ-HCH indicates the different pesticide composition between these two regions and is the potential marker for the source of the OCPs. Many other OCPs with different residue patterns have also been found for the first time in the two regions. No heavy metal contaminant was found in the investigation regions.
