Ground-based quantitative measurements of mercury species
Research gap analysis derived from 3 earth_science papers in our local library.
The gap
There is a lack of ground-based quantitative measurements of mercury species in ambient air. The simulation-based emission inventories are largely based on emission factors and industrial use, which may not be consistent with changing scena
