Coal is the dirtiestfossil foil in the world that emitting carbon-dioxide in the atmosphere andcauses a greater harm to the environment and human health. Coal is acombustible carbonaceous rock, formed from accumulated vegetable matter thathas been altered by decay and various amounts of heat and pressure overmillions of years. Contribution of coal in the economy of a country isessential.
But the environmental impact of coal mining is immense to theatmosphere and human and other ecosystems in the earth. Coal is the primarysource of energy that uses to meet the huge demand of energy that is to beconsumed to meet the development of the society. There are mainly two way ofexcavation of this fossil called opencast and underground mining. Both of theseprocedures are extremely harmful to our environment especially to ouratmosphere and aquatic ecosystem. Coal is mainly used for energy sector whichis considered as the fuel of development of a nation.
This is the mostavailable and used fossil foil in the earth. In this age of development coalindustry is a major sector of industrial for both developed and developingcountries. But this process of development is immensely deteriorating theenvironment. The use of electricitygenerated by coal has great impact n health and wellbeing of people. It hascreated thousands of employment opportunities to the people of the modern time.But use of coal to the power generation has created thousands of problems tothe human health and to the ecosystem we are belonging. Air pollution caused bythe coal combustion is prone people to different types of damages to the humanhealth such as cardiovascular diseases, respiratory problems and abnormalneuropsychological development to the children. Most importantly the contributionto the coal combustion to the climate change and the anthropogenic gas emissionhas the most important things to be considered.
Among the pollution by coalcombustion the air pollution is more deathly to the human and to theenvironment. When coal is burn to produce electricity different air bornepollutants are emitted such as Carbon dioxide, Sulfur dioxide, nitrogen oxide,acids gases, mercury, arsenic, nickel and others. Before use coal in producingenergy at first it has to be mined then washed and transport. After using inthe power plant it is to stored or disposed. All of the procedures stated aboveis threatening to the environment and ecosystem.
The disposal of coal miningand burning to the energy sector harmfully affected to the wetlands and humanhealth. Throughout the life cycle of his fossil its disposes number ofpollutants and causes threat to the environment.Impact of Coal Pollutionon Human International EnergyAgency reveals a report that claims coal based energy production in the world was8572 TWh in 2010. The coal industry is popularizing with the days.
Though someinternational pacts and agreements are signed by the international communitybut the mining and other activities is not being stopped. So it imposescontinuous threat to the human health and our ecosystem. The impact of coalpollution is severe to the human health. Physical Effects A November 2009 report on the effects of coal by the Physicians for Social Responsibility (PSR) found that coal combustion affects notonly the human respiratory system, but also the cardiovascular and nervoussystem. Respiratory EffectsØ According to a 2004 report bythe Clean Air Task Force, fine particulates from power plants result in nearly 24,000annual deaths, with 14 years lost on average for each death.Ø Burning of coal contributes to smog thatreleases different harmful gases like oxides of nitrogen which react withdifferent organic compound in the day light that produce ozone gas the mainelement of smog.
Air pollution affects the lung of the human and these anthropogenicparticles are badly affecting the respiratory system.Ø Coal combustion causes air pollution that isconsidered as the main reason of asthma that affects 9% of the children of allwho are porn to asthma attack. This is bigger concern that asthma attack to thechildren is increasing dramatically than ever.Ø Coal combustion causes ozone exploration thatcauses different diseases like cancer and damage functions of human organ.Ø Coal pollutants also play arole in the development of chronic obstructive pulmonary disease, a lungdisease characterized by permanent narrowing of airways.
Cardiovascular Effects Ø Air pollution causes cardiovasculardiseases that are resulted from coal combustion. Different studies haveidentified that coal combustion is directly or indirectly causes respiratoryand cardiovascular problem to the human and animals. It causes pulmonaryinflammation and oxidative stress. Pollutants emitted by the coal combustion inthe air combustion are caused different cardiovascular diseases like arteryblockages leading to heart attacks, and tissue death and heart damage due tooxygen deprivation. Research showed that on an average 38200 people diedbecause of coal pollution in a year.Ø Studies shows that oxides ofnitrogen together with the other pollutant particles are potentially fatal andaffects the cardiac rhythm of human.
Ø The cardiovascular effectsof long-term air pollution are also considered. The exposure of pollutants overlong time increase mortality rate of the people. So it has a significant correlationbetween these two factors that decreasing the pollution increase the lifeexpectancy of the people of the particular area. The more regulations enforcementwill be enacted to control air pollution caused by the coal combustion.
Researchshows that the metropolitans with less pollution will have a higher lifeexpectancy of the people.Ø A studies of American MedicalAssociation shows that on 34 people who are suffering from heart attack atdifferent level of inhaling different pollutants from air that is polluted fromthousand of causes concluded that pollutant particles of the air is responsiblefor increasing risk of the heart attack. Ø The problem of the miningworker is severe than the normal people.
People associated with mining andcombustion is the most victims of the coal pollution and cardiovascular problemrelated to coal pollution.zz
