Precursors (Supporting the Aerosols and Ozone ECVs)  
DEFINITION
  • Precursor species include nitrogen dioxide (NO2), SO2, CO and formaldehyde (HCHO). Surface atmospheric concentrations of NO2 and SO2 may reach levels that are directly harmful to health and lead to detrimental environmental impacts through acid rain, although emission controls have lowered concentrations over time in many regions.
