报告简介Arsenic and Mercury are toxic and mobile elements in the shallow Earth’s crust. The both elements behaves similarly related to the plate tectonics; i. e., high concentrations of those elements appear in the tectonically active areas of the Earth, such as subduction zones including volcanic fronts and active orogenic belts. However, it is interesting that the mercury occasionally appears at the fore-arc region where no active volcanoes present. In the lecture, cycles of arsenic and mercury related to the plate tectonics will be reviewed.
