Beij<strong>in</strong>g.The types of vehicles ply<strong>in</strong>g <strong>the</strong> roads <strong>in</strong>fluence<strong>the</strong> nature of air pollutants. Diesel vehicles areassociated with particulate emissions and gasol<strong>in</strong>evehicles, <strong>in</strong>clud<strong>in</strong>g two- and three-wheeler vehicles,with nitrogen oxides and hydrocarbon emissions.Increas<strong>in</strong>g traffic congestion <strong>in</strong> many of <strong>the</strong> cities <strong>in</strong><strong>the</strong> subregion has exacerbated <strong>the</strong> problem.Large cities <strong>in</strong> <strong>GMS</strong> countries are <strong>in</strong>creas<strong>in</strong>glyfac<strong>in</strong>g problems with urban ambient air quality.In most cases, <strong>the</strong> transport sector is <strong>the</strong> largestcontributor to air pollution. Pollutants of ma<strong>in</strong>concern are particulate matter (PM), especially verysmall particles (known as PM 10and PM 2.5), nitrogenoxides, and hydrocarbons. Increas<strong>in</strong>g nitrogenoxide levels contribute to an <strong>in</strong>crease <strong>in</strong> ozonelevels. On average, <strong>the</strong>re has been a moderate toslight decrease <strong>in</strong> pollution levels of sulfur dioxide,which are now below <strong>the</strong> guidel<strong>in</strong>e values set by <strong>the</strong>World Health Organization (WHO)—prov<strong>in</strong>g thatair quality management policies and measures canwork <strong>in</strong> Asia.
