Conclusion
Conclusion

  • The findings

    • Short Term Values: findings can be used

      200µg/m3

    • Long term Values: Can not be found


Limitations in this study testing no2
Limitations in this study testing NO2

  • It is impossible to measure the long term health effects of NO2 on a population. Our pollution is made up of many different gases, odours, chemicals so it we are unable to isolate this one chemical and show that it is the cause of all these health problems


Pollution
Pollution

  • Sulphur Oxide(SOx)

  • Nitrogen Oxide(NOx)

  • Carbon Monoxide(CO)

  • Carbon Dioxide (CO2)

  • Volatile Organic Compounds

  • Paticulate Matter

  • Persistent Free radicals

  • Toxic Metals

  • Chloroflurocarbons(CFCs)

  • Ammonia (NH3)

  • Odors

  • Radioactive Pollutants

  • Secondary pollutants include:

  • Smog

  • Ground Level Ozone(O3)

  • Peroxyacetyl nitrate(PAN)


Conclusion

  • The amount of NO or NO2 in the ambient air depend on the surroundings and if there are sources of these pollutants nearby it will affect data.

    Example: Amount of NO and NO2 levels near highways and high traffic areas are higher compared to urban or rural areas.

  • Studies being done on animals to test the effects of NO2, was given had higher concentrations then what is found in normal ambient air

  • Difficult to measure populations exposure
