Air pollution

        Pollution is aserious problem, that threat our life on the Earth. We can find alot kinds of pollution that effects our life badly like: air, water, hearing, soil,......etc. The change of the natural component of air, water, and other things in our life leads to cause this pollution. The more the proportion of the air pollution arise, the more the diseases spread in egypt. Air pollution means the change of the component of air by opposing to chemicals,particulate matter,or biological materials that cause harm or discomfort to humans or other living or damage the natural environment into atomsphere. We find this pollution surrounding us in every moment even we breathe this polluted air and there are alot of factors which responsible for this pollution.
        According to sources of air pollution ,it refers to the various location ,activities ,or factors which are responsible for the releasing of pollutants in the atomsphere. On one side  haman sources(activities), this kind related to burningdifferent kinds of fuel. i:(Stationary sources)include manufacturing facilities and waste incinerator ,as well as furances and other types of  fuel _burning heating devices . ii:(Mobile sources) include motor vehicle ,air craft and the effect of sounds. iii: Military works. iv:Chemical ,dust and controlledburn practices in agriculture ,and forest management. On another side the environment also contibute in this pollution by its natural factors like. i: Smoke and carbonmonoxide from wildfires. ii:Volacanic activity ,which produce sulfur ,chlorine and ash particulates. iii: Dust from natural sources, usually large areas of land with little or no vegetion. The increase of air pollution leads to arise of heat tempratuer and Stratosheric Ozone depletion. also it leads to make 2.4 million people die each year from cause directly to air pollution. Also it effects on cystic fibrosis, a study from 1999 to 2000 by the Univesity of Washington showed that patients near and around particulate matter air pollution had an increased risk of pulmonary exacerbations and decrease in lung function. With the increase of spreading this disease as areaction of air pollution, chlidern infected by this disease. Also the birth rate become low. This pollution also emerge more in poor countries that lacks wareness and education.
       There are various air pollution control technologies and land use planning strategies available to reduce air pollution. The following items are commonly used as pollution control devices by industry or transportation devices. They can either destroy contaminants or remove them from an exhaust stream before it is emitted into the atmosphere. We should make control using of particulate ,scrubbers ,mercury ,dioxin and furan. Also the government has an effictive role to help in decrease this pollution by putting alot of rules that helps in this pollution ,and put harm punish to whom be dissient.
       At the end ,we notice the danger of this problem and we should cooperate together to face this problem. As this problem threaten our life on the earth and other kinds of creatures. Also we should think that our God give us nature to use it in the correct way ,not to harm its creatures and change its component. We should keep our health because it amarvelous bless ,that nothing can compensate us for it.
