Scientists quantify a previously overlooked driver of human-related mercury emissions.
Scientists quantify a previously overlooked driver of human-related mercury emissions.
About 10 percent of human-made mercury emissions into the atmosphere each year are the result of global deforestation, according to a new MIT study.
The world’s vegetation, from the Amazon rainforest to the savannahs of sub-Saharan Africa, acts as a sink that removes the toxic pollutant from the air. However, if the current rate of deforestation remains unchanged or accelerates, the researchers estimate that net mercury emissions will keep increasing.
“We’ve been overlooking a significant source of mercury, especially in tropical regions,” says Ari Feinberg, a former postdoc in the Institute for Data, Systems, and Society (IDSS) and lead author of the study.
