Observations

A large number of activities have been carried out in different regions of the world aiming to assess the level of mercury (Hg) in ambient air and precipitation, its variation over time, and how it varies with changing meteorological conditions. Recent studies have highlighted that in fast developing countries (i.e., China, India), Hg emissions are increasing in a dramatic fashion due primarily to a sharp increase in energy production from the combustion of coal [Mukherjee et al., 2009; Pacyna et al., 2010; Pan et al., 2007; Streets et al., 2005; Streets et al., 2009; Wu et al., 2006].
