Phosphine, a ubiquitous trace gas in the atmosphere, acts as a carrier of gasous phosphorus in the biogeochemical cycle. The research of phosphine will show new light on the mechanisms of how the phosphorus supplement influence the biogeochemical cycle and global warming. In this paper, we detect the phosphine in Arctic Pole area for the first time. The result shows that matrix-bound phosphine (MBP) exists in all the samplings. Phosphine distributions varied with different environmental origins. Average phosphine concentrations in tundra soil, lake sediments, sea sediments, seabird-droppings and deer guanos were 14.17 ng/kg dry, 35.44 kg dry, 67.20 kg dry, 32.9 ng/kg dry, and 25.52 ng/kg dry respectively. Correlation analysis shows that there is an obviously positive correlation between Porg and MBP. It could be concluded that anaerobic decomposition of Porg and the mechano-chemistry action of the rock probably are the possible reasons explaining the mechanism of MBP production in Arctic Pole area.
