. Mercury will enter the aquatic food chain after being methylated by microorganisms, which will endanger the ecological environment.
During the Multidisciplinary drifting Observatory for the Study of Arctic Climate , the research team conducted a one-year observation of GEM in the Arctic Ocean using a cold vapor atomic fluorescence spectroscopic Hg analyzer Tekran 2537 and constructed a generalized additive model to analyze the summertime data.
The potential source contribution function analysis revealed that the oceanic evasion during summertime mainly occurs in the MIZ. Hg evasion flux in the MIZ was estimated to be 56 ng mThrough multidisciplinary analysis of the observational data, the team proposed the driving mechanism of the Hg evasion in the MIZ.
