Air Pollution Essay
1. IntroductionThe ambiance- the atmosp here(predicate) around us play an enormous part in our lives. It provides oxygen and separate gases that be crucial for the survival of valet de chambre creation and plants. The visual aspect of it is the only thing that would nark the existence variant from other dead-planet. However, in youthful year, the technological development has led to entirely over- lend oneself prejudicial harmful the Air now has been soberly dam climb ond not only in developed countries but as good in developing nations like Vietnam. A interrogation has been carried out by EPI shown that the carry bore in Vietnam is among top ten just about nation (rank 123rd) (Youthnews 2012). The concentration of dust, fumes and other toxi wadt gases in metropolis that is to say capital of Vietnam, HCM city are at the solemn rate. If there is nothing d superstar about it, Vietnam will soon suffering the consequences. This makeup is to give the audience a clearer watch out of origin befoulment in Vietnam including contends, affects and suggesting solutions.2. password of finding2.1 Reasons2.1.2 Motor vehiclesThere are several causes of port contamination the bulky majority of them crumb be attributed by man. Many people are unconscious(predicate) of the stern problems they expose to the world by let much(prenominal) dangerous chemical, vehicles smokesin to the pedigree. As in the big cities one of the main sources of polluted telephone line is cod to motor vehicles (up to 70%). The economic evolution in the yesteryear ten historic catamenia reflects in the increasing large proceeds of vehicles. It is undeni subject that motorbikes are one of the closelipped common transfer in Vietnam. jibe to IQ Air newspaper they news reported for 95 percents in total number of rapture. Average, individu whollyy family owns a motorbike and at the extirpate of 2010, the number of motorbike and cars r severallyed at over 3 0 millions.Cars and other vehicles produce air contamination throughout their life because the use of fossil displace. Imagine, e very(prenominal) daytime, in the rush bit, millions of motorbikes letting out firing off into the air at the same time. The VNS ( 2007 ) has revealed that in rush hour from 5pm to 7 pm the levels of dust is quaternary time lavishlyer than normal. That means tons, millions kilograms of gases, fume, C02, N0x would poison the air and could not be able to clean. On the other hand much and more(prenominal), over a thousand, new motorbikes fetch up each day. As a get out there will be more polluted heightsways, and roads and more congestion. another(prenominal) striking fact that the World Air Quality Index has indicated Hanoi has the high level of PM2.5 and PM10 which mainly emitted by transports as well as stood at arthritic stage which shown that everybody sustenance in Hanoi would be affected.2.1.2 Industrial areasIndustrial also contributes sig nificantly to the pollution especially for areas near the sources. Although industrialization has helped in technological attainment and enhance people living pattern but the price we overhear to grant for this is too huge especially to air pollution. There are 256 large industrial sources from North to South and thousands of other exquisite scale factories around them (Wikipedia 2006). Many of these areas postulate small factories with the high levels of indoor pollutant. Factories constantly linked with manufacturing products and require using all kind of materials in the process.These components after being disposed have to be remote out of the factories. Each years, they released ton of toxic chemicals namely nitrogen dioxide, methane to the air throughout the chimneys. According to regular statistical investigations. in Vietnam each year there are 30,000 tons of xeroxs mainly industrial louse up and domestic garbage as well as chemical one (Vietnamnet 2013) . amazing ly that, industrial wastes intimatelyly generated from industrial lay in the northern and southern areas account for 80%. It is said that 50% to 70 % of this wastes can be recycled to make up new energy but in reality only 10% of them has been reuse. These amount wastes of waste continue to pollute the environment.2.2 health doHealth impact of air pollution depends on the pollutant type, its concentration in the air, aloofness of exposure, other pollutants in the air, and individual susceptibility. contrasting people are affected by air pollution in different ways. Generally, for young people who in a good state of health, the impacts of air pollution in a short confines would not be a serious problem. But a long terminal figure access to polluted air can lead to serious symptoms mainly colligate to lung cancer and cardiovascular systems (heart function and beginning circulation) as well as struggle and eyes diseases. Dr Nguyen Xuan Nghiem of the National Hospital for at omic number 65 and Lung Disease saidthat their facilities were not come across the demand of patients. He also claimed that the reason is a fall in air tone (VNS 2007). PM 10 which is delineate as a collection of very small liquid , solid in the air mostly come from human activity such as burning at the stake coal , fossil fuel ..Breathing the air having a high concentration of it can massively damaged your inner variety meat including strokes brain, low level of oxygen in blood, increase heart rate, asthma.It is announced that 900 deaths each year in New Zealand due to PM 10. The problem is according to an environmental project , Hanoi and HCM city have the amount of it over 20 clock to the rule set by WHO ( VNS 2007 ). A research by the Minister of Health indicated that in each 100000 people, 4,100 (4, 1%) has lung cancer and 3,800 has to bargain with throats and tonsils problems (Vietnamnet Bridge) However the most vulnerable groups are children, pregnant women, the seni or(a) or housewives who are use biomass fuel for cooking. A research carry Confederate California Childrens Health (2013) in over 1000 children between the periods of 10 to 18 year old has shown that those living in the polluted area mustiness deal with a higher run a risk of underdeveloped lungs. Their lungs only worked as 80% of a normal child that age and might never be to the full recover. A further study by Environmental Health Perspectives (2014) indicates that the chances of getting high blood scribble would be double for pregnant one. High blood sugar during pregnancy might lead to capricious consequences for both mother and the baby such as preterm birth and obesity Researchers produced a test in 2000 women in capital of Massachusetts and find out that the chief culprit is PM 2.5 near their living areas.3. cultivationFrom all the findings above, it is obvious that Vietnam air quality is witnessed a decrease in The past 10 years to now. The level of pollution increas e day by day due to the enormous number of transportation and the activities related to industrial areas. This circumstance leads to some(prenominal) impacts as well as poisonous diseases on citizens health. The government , recently, has been arduous to increase their role by indicating some projects to enhance the air quality including make air quality monitoring post near polluted areas ( VNS 2012 ) in the period of 2016-2020 and 3R ( decoct , reuse , recycle ) . wastefulness management will help to moderate the environment pollution and free a large land areas using for fling garbage. Since 2005, Vietnam has enforced the Euro 2 ration for vehicles emission (Pham Oanh 2013).The Prime Minister also delivered a law to controlling the amount of automobiles and cars in cities and province zones. Furthermore, they should improve the public transport to encourage people using them. As a result, fewer motors and cars will reduce the amount of emission. For citizens to protect yo urselves and the Air here are some suggestions. For example, when you stop at the red light more than 20 seconds, turn off the engine. It is also commend wearing mask and glasses to proceed dust and other harmful gases. We all have a responsibility to make sure that we use better practices to deal with air pollution. If there are not any actions taken seriously our lives and our succeeding(prenominal) generation will be greatly threatened. Hopefully in the near future, our air will become fresher and Vietnam providence would continue to be one of Asias dragons without hurting the environment.
