Status of persistent organic pollutants and heavy metals in surface water of Arctic region

Trace pollutants in the surface water of the Arctic region have been analyzed by the capillary gas chromatography with the micro-electron capture detector (GC-muECD), the gas chromatography-mass spectrometry (GC-MS) and the inductively coupled plasmas-mass spectrometry (ICP-MS). Compared with previo...

Description
Summary:Trace pollutants in the surface water of the Arctic region have been analyzed by the capillary gas chromatography with the micro-electron capture detector (GC-muECD), 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 alpha-/gamma-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.
