Natural Resources Dust emitted from some natural sources, which usually is in the vast areas of land that contains a little of plants or plant life in which non-existent at all. Methane emitted from the digestion of foods through the process of animals (animal) like cattle. Radon gas emitted from radioactive decay in the earths crust. Radon gas from the colorless, odorless gas that arise naturally in the environment and is also a radioactive gas that consists of dissolution of the element radium. But is Alrado gas from the gas, which represents a risk to human health. It is possible that accumulates radon gas emitted from natural sources inside buildings, especially in confined spaces such as basements. It also occupies second place in the list of causes of lung cancer, after cigarette smoking. Smoke and carbon monoxide Almenbosan of forest fires. Volcanic activities issued Anhaalkiprit, chlorine and ash particles. Emission of air pollutants factors The emission of pollutants factors (polluted) air are representative values that link between the amount of a pollutant emitted into the ambient air and the activity associated with the emission of the contaminated material. Usually the expression of these factors by the weight of contaminated material divided by the unit weight or volume, or the distance or the activity that sending a contaminant Duration (For example, the number of kilograms of material emitted per gram of Kilwa from burning coal). And facilitate such factors evaluation process pollutants emitted from various sources of air pollution. In most cases, these factors are just rates available for the college degree of acceptable quality of the data as it is generally representative of the ratios of these rates are considered long-term. We have the United States Environmental Protection Agency published a compilation of data on the emission of air pollutants for many industrial sources factors. It also has all of the United Kingdom, Australia and Kendaobed other countries, in addition to the European Environment Agency to publish such a set of data.
