In this paper,we use pre-column 2 times low-temperature cryo-trap enrichment—gas chromatography(GC) /nitrogen and phosphoms detector(NPD)to detect and analyze phosphine in Arctic pole area forthe first time.The results show phosphine exists in all of the samples in Arctic pole biosphere and phosphineconcentration in Arctic atmosphere is between 18.54~132.18 ng/m^3,almost the same as that inAntarctic atmosphere;phosphine concentration in Dalian bay sea surface sediments is between 116.8~554.3 ng/kg,almost the same as that reported in Jiao-zhou bay.Our research of phosphine will shednew light on the mechanisms showing how the phosphorus supplement influences the biogeochemical cycleand global warming.
