Trends of GEM and criteria pollutant concentrations (IMAGE)
Caption
On the left can be seen a much larger decline in GEM concentrations in China than elsewhere in the Northern Hemisphere. On the right is the trends in criteria pollutant concentrations in China. These trends suggest the co-benefits of emission control measures contributed to the reduced anthropogenic mercury emissions and led to the GEM decline in China. Figure by Xinbin Feng.
