Environmental significance from the article :
"Most research on gaseous elemental mercury (GEM) in the atmosphere has been conducted in the Northern Hemisphere, while the available data on atmospheric GEM concentrations from the Southern Hemisphere, particularly from urban areas in sub-Saharan Africa, are very limited. At the same time, global emission estimates indicate increasing GEM emissions in Africa. We present here for the first time spatially resolved GEM concentrations across an urban area in the Southern Hemisphere (Dar es Salaam, Tanzania), determined using a passive sampling technique. Signs of signicant GEM sources were observed in the urban area, but they remain unidentied. We therefore recommend further studies in this area and other urban areas in sub-Saharan Africa to gain further insight into emissions and sources of GEM."
