Short-term exposures to SO2 can harm the human respiratory system and make breathing difficult. The largest sources of SO2 emissions are from fossil fuel combustion at power plants andother industrial facilities. Other gaseous SOx (such as SO3) are found in the atmosphere at concentrations much lower than SO2. Emissions that lead to high concentrations of SO2 generally also lead to the formation of other SOx. See the SO2 Standards Home Page for documents from the current review of the SO2 NAAQS. At high concentrations, gaseous SOx can harm trees and plants by damaging foliage and decreasing growth. EPA’s decision is based on its judgment that the current NAAQS protects the public health, with an adequate margin of safety, including the health of at … Feature Info .
