Pollutants, Volume 4, Issue 4

2024 December - 6 articles

Cover Story: The U.S. Clean Air Act and subsequent amendments limited emissions from fuel combustion, industrial activities, and automobiles. Despite reduced emissions, the legacy of metals like Pb, Cd, and Cu persists in rural Appalachian forests. This study evaluates throughfall and litterfall concentrations and fluxes of Cu, Zn, Cd, and Pb in temperate forests along the Appalachian Mountain range over five years. We show that while throughfall fluxes of Cu, Cd, and Pb have decreased significantly since the 1980s, Zn and litterfall fluxes of Cu, Zn, and Cd remain comparable or greater. This suggests that trees retain and recycle Cd, Cu, and Zn, extending their pollution legacy for decades. View this paper
