Tackling air pollution just became more important after scientists found evidence that soot particles - also called black carbon - were found to be embedded in the fetal side of placentas
Five years of testing at sites across the Arctic tracked seasonal fluctuations and sources of black carbon, or soot, which contributes to global warming and ice melt.
One million pounds of carbon were released into the atmosphere following the 2010 Deepwater Horizon Spill, according to researchers from the National Oceanic and Atmospheric Administration (NOAA).
