Air Pollution In Cambodia Essay

After 1993, Cambodia economy has been increase rapidly and the scale of the city also expended but at the same time it leads to level up of air pollution (Furuuchi et al., 2006). Many emission sources of air pollution from anthropogenic are concerned, especially the rising number of vehicles has resulted in even greater pollution and growth in the population, resulted in a large amount of energy consumption: electricity, automobiles, household, field burning etc. (Furuuchi et al., 2009). Most of the air pollution came from the traditional energy and commercial or modern energy. Modern energy was classified as petroleum products, ignites and coal, and was used in the transport, household sectors and industrial sectors whereas traditional energy was identified from the burning of fuel wood, paddy husk, and charcoal, significant energy sources for households, which commonly are charcoal and wood. Cambodia is not heavily industrialized country but most of the factories still use old technology and not paid attention on the environmental pollution as well as air pollution and never conducted environmental impact assessment and they are located in the Capital City of Phnom Penh. Most of them are garment factory. Anyway electricity supply in Cambodia is not enough so many service sectors use their proper generator, especially the hotels. They usually put the generator next to their service along de road. There are 282 hotels in Phnom Penh (http://www.hotelscombined.com/City/Phnom_Penh.htm).

Phnom Penh is the largest city in Cambodia with highest population and the number of vehicles increases day by day, so the traffic jams has been occurred frequentl...

...operties. Char is weak light absorption with a strong spectral dependence while Soot is strong light absorption characteristics with little spectral dependence (Han et al., 2010). By the way, Particle matter (PM) was associated with cardiovascular mortality and morbidity. Spontaneous Hypertensive Rate was the effect of single intrataracheal of PM2.5, it increased the parasympathetic nervous activity and decreased the heart rate (Ryoko, 2008). PM consists of a complex mixture of solid and liquid particles of organic matter, mineral dust, secondary inorganic aerosols and trace metals, as well as water and unspecified compounds (Katarzyna et al., 2011). In order to avoid the impact negative on public health, climate change and keep an economic growth with acceptable environmental loads, the investigations of emission sources of air pollutants are essentially important.
