Seems like our Nitrogen Dioxide, NO2(g) level within the lower atmosphere level is quite high in Singapore.
2NO(g) O2(g) 2NO2(g from the article, it shows that as filemagic zip archive data concentration of air particulates (unburnt hydrocarbons) increases due to incomplete combustion of fossil fuels in vehicle exhaust fumes, there is also an increase in the concentration of nitrogen dioxide, NO2(g).
