One area of research is how air pollutants interact with air particles like snow. A new study in Environmental Science shows that snow acts like a magnet for pollutants, taking them out of the air.
Scientists using a microbe that occurs naturally in eastern cottonwood trees have boosted the ability of two other plants – willow and lawn grass – to withstand the withering effects of the nasty industrial pollutant phenanthrene and take up 25 to 40 percent more of the pollutant than untreated plants.
