Water is required for domestic, industrial, agricultural and fishery production for each purpose analytical study of water is essential because impure water cannot be used for domestic, industrial, agricultural and fishery purposes. Identification of air pollution sources and characteristics of the pollutants are essential factors on air quality control, particularly on determining mitigation or prevention actions. Moreover these factors are important on predicting effect and trajectory of the pollutants on the environment so that an appropriate approach can be done. Mainly air pollutants are particulate matter, SOx, NOx, CO, VOCs, and lead. Developed countries contribute more on emission of CO2, SOx, and NOx compare to developing countries, which emit more CO, hydrocarbon, and particulate matter. This is attributed to gap in pollution reduction technology, wherein developing countries have not reached optimization in combustion process.
