  • Trends in on road vehicle emissions and ambient air

    Introduction. On road vehicle emissions contribute to deterioration in ambient air quality, particularly in urban areas. Oxides of nitrogen (NO x) and volatile organic compounds (VOCs) emitted by vehicles are precursors to the photochemical formation of ozone (O 3) and particulate matter (PM).NO x is also a contributor to acidic deposition. Additionally, NO x and carbon monoxide (CO) from on
