Carbon Monoxide
Carbon Monoxide is a tasteless, odorless and colourless gas formed when carbon containing substances (fossil fuels) burn incompletely because of insufficient oxygen. The gas is highly toxic above the concentration of 35ppm and can lead to death within minutes. Source: 10% of the total CO emission comes from fuel combustion in homes and industries, where as emission from mobile sources such as vehicles and construction equipment’s contribute the rest 90%. Health Effect: Exposure to lower level of CO can cause headache, nausea, fatigue, loss of alertness etc. Long term exposure of CO increases heart and circulatory disease and can even cause unconsciousness or death within minutes. Environment Effect:
  • Climate Change.
  • Global Warming.
  • Photochemical Smog.
  • Acid Rains.
Recommended Standard: The recommended national air quality standard for CO is 35ppm for 1-hour exposure and 9ppm for an 8-hour exposure period. Applications:
  • Urban air quality monitoring.
  • Power stations & furnaces.
  • Chemical Industries.
  • Steel Mills.
