Causes of Air Pollution

Air consist of breathable oxygen which is the most important factors for the existence of life on earth and continuously supports life on Earth. With the industrial revolution the fresh and pure air has been contaminated due to the excessive amount of increase pollutants. The presence of any substance in the air over the natural concentration level potentially impacts the effect.

 Air pollution is mainly caused by the release of the harmful substances in atmosphere by the use of the fossil fuel and emissions from the different industries. This released substances becomes the reasons for diseases and even death. This pollution also harms animals, food crops and in turn impacts to the food chain as well as other living organisms in the environment. This has a hostile effect on our environment. For the urban areas root causes of air pollution is traffic, industrial factories.  As this releases substances/pollutants in air that damages the ecosystem.

Excessive pollutants are one of the leading reasons for the death throughout world as this causes stroke, lung cancer, and other respiratory related diseases for   the humans. In this   data analysis project the main objective is to explore air quality in the different regions of the united states. For the analysis of the selected dataset, the IBM Watson is used.

In this industrial age, air contamination/pollution cannot be wiped out totally, however steps can be taken to diminish it. The administration has to created, and keeps on creating, rules for air quality and statutes to limit discharges with an end goal to control air contamination. On a singular dimension, we can diminish our commitment to the contamination issue via carpooling or utilizing open transportation. Also, purchasing vitality proficient lights and machines or generally lessening our power use will diminish the contaminations discharged in the generation of power, which makes most of modern air contamination

In this project it is assumed that, if a thorough analysis of the selected dataset can be carried out then, it is possible to identify patterns in the air pollution levels as well as correlating factors that has been putting effect on Air Pollution in the overall nation. Additionally, this part of this project has been intended to study the impact   or trend in the different days of the weeks, in different states, or the numerous pollutants as well as their intensity in the air.

 For the selected dataset, the following are the pollutant elements that are used and analysed in the analysis. Following are the details such as origin, impact of these pollutants are provided.

Impact of Air Pollution

Carbon Dioxide or CO₂ – This element is considered as the most emitted air polluting element. From the different analysis it is found that the amount of CO2 is increase every day in the earth’s atmosphere due to the deforestation as well as use of fossil fuel.

SO_2 (Sulphur Dioxide) – This pollutant is mainly produced from the volcano eruptions as well as from different manufacturing industrial processes. In addition to that, Coal as well as petroleum/fuels contains sulphur compound in them and the combustion of this products generates excessive amount of sulphur dioxide.

Furthermore, oxidation of SO2 with the catalyst like NO2, different forms of H2SO4, results in acid rain. For his is one of the causes for concern due to its adverse impacts on the environment.

NO2 (Nitrogen Dioxide) – This pollutant is released from high temperature combustion processes as well as due to the thunderstorms in storms by electric discharge. In this case, this has been the most prominent kind of pollutant that has reddish-brown coloured having a biting and sharp odour.  

Carbon Monoxide or CO – This has been one of the colourless, toxin and odourless, gas that contaminates the air.  This is released due to the incomplete combustion of fuels like coal, wood or natural gas, exhausted gas from the gases are considered as major source of this monoxide.

Particulate Matter – Particulate matters (PM), atmospheric specific matter that has been consisted of tiny liquid and solid particle that is suspended in the gas.

Some particulates naturally remain in the air due to the volcanic eruptions, dust storms, wild and forest fires along with living vegetation and sea spray. Because of the fact human activities has been like fuel o burning fossils, combustion at power plants as well as various industrial processes are also responsible for generating significant amounts of particles. The average value of anthropogenic aerosols due to human activities accounts. This has been for about ten percent of the overall environment. The rise in levels of the pollutant particles within the air has been leading various issues like health such as lung cancer, heart disease and so on.

Ozone – ozone is a key gas for the troposphere.  On the other hand, the Ground level O3 is created from VOCs and NOx. Further, there is also element of particular regions of the stratosphere that has been also known as the ozone layer. With the abnormal and high concentrations due to the use of the CFC and combustion of fossil fuel and creates smog.

Other greenhouse Gases-Methane is one of the worst effective type of greenhouse gas that has been found to be giving rise to global warming. Different kinds of hydrocarbons such as VOC has also been regarded as the vital greenhouse gas. The reason is that these gases are responsible for creating ozone gas in the lower atmosphere sections and prolonging the methane in the lower sections of atmosphere.

The following are the column names that are recorded in the dataset. These are listed below;

The State Code has been found to be allocated by the US EPA. This also involves the County code of counties, Site Number that are been allocated by the US EPA, addressing of  the monitoring of site,  State details, County of the monitoring site, City, various Local  Date, steps of  four kinds of pollutants. These are O3, SO2, O3, NO2 measurements for NO2, measurements for NO2, and different types of arithmetic mean of concentration of NO2. This is for a particular day, measured as per air quality index. Besides, it has also included the NO2 first Max Value that is retrieved for NO2 concentration for a given day, NO2 max Hour for the highest value in a hour.

The edited dataset includes 4 years of data in it. Following dash board displaying the same.

In the following dashboard, the NO2 max value is compared by states in order to find out the recorded maximum NO₂ in the states.  

From the above created dashboard, it is evident that the maximum value for NO₂ is recorded for the California state.  Other states include Arizona, Illinois, New York, Pennsylvania and Texas.

For the next dah board, the NO₂ Max value is measured over the years.

Here it can be said that, the amount of NO₂ has been reduced from the year 20007 to the year 2010.

In the following, dashboard the highest values compared by different states in the country. In this analysis, it is found that, for the years from the year 2007 to 2010 maximum values is always recorded from the state California.

In order to be more precise, the month with the maximum value of NO₂ is recorded is analysed.

Here it is evident that the highest spike is for April 2008, therefore in this month the air was polluted with the NO₂ and the lowest is recorded in the month of December according to the selected dataset.

Dashboard: NO2 Max by States

In the next dashboard, the trend of mean of NO₂   in the air is measured.

The trend shows the same results. i.e. the mean value for NO₂ is also decreasing throughout the time period.  The four blocked charts above are depicting the results. Here, it is interesting to observe that the values are high in the initial months of the year 2007 and the decreased value is recorded in last quarter of the year in 2010.

Here, the value of the NO2 AQI is compared by the states that shows the California has the worst air quality among all the countries.

Following is the dashboard that shows the trend of the AQI.

The graph depicts that, there is significant decrease in the AQI levels (almost 38%) for NO2 and thus making the Air quality better.

Following is prediction for the NO₂ AQI   in the country.  The maximum and minimum predicted value is recorded with 53.57 and 2.78.  The maximum value is predicted using the rules,

 NO2 max value <=10.5  

NO2 mean <=4.7

State: California

NO2 first max hour <=5

CO mean>0.15.

Now, the statistics pollutant SO2 is measured.

In the analysis, it is found that maximum SO2 mean for the state Pennsylvania.  The other two states that have highest mean value   of SO2 are New York and California.

In the analysis of the first max value of SO2, the results are same for the states. Which is depicted below;

In the similar manner, the SO2 AQI is visualized for the states and the Pennsylvania is the worst state with this pollutant.

The SO2 AQI values is compared for the different years.

Here, it can have stated that, the amount of SO2 pollutant is decreasing at higher rate compared to the NO2 pollutants. Here the highest value is also recorded in the year 2007 and had good decreasing rate when it reached in 2010.

In the next part the mean of O3 is measured over the years.  This analysis resulted in the following dashboard. 

Here, it can be stated that the amount of O3 in the environment has been the same throughout the time period except the year 2009 in which it decreased a little bit.

At last the O3 mean is compared by the states.   For O3, the following dash board is created.

Here, it can be stated that the maximum mean is recorded for the Wyoming. Other, states that have higher O3 are Tennessee, Ohio, Missouri, Indiana and few more.  

Dashboard: NO2 Max Value Over the Years

For  the O3 AQI,  the following dashboard is created.

Surprisingly, even though California does not have high amount of O3 mean value but the AQI is much high compared to the states having higher count or mrean.

Air quality assessment is an essential method to screen and control air contamination. The attributes of air supply influence its appropriateness for a particular use. A couple of air contaminations, called criteria air poisons, are normal all through the world. These polluting elements can harm wellbeing, hurt the condition and cause property harm. The present criteria toxins are:

• Sulphur Dioxide (SO2).
• Particulate issue (PM)
• Nitrogen Dioxide (NO2)
• Carbon Monoxide (CO)
• Lead (Pb)

This system of Air Quality index s encompassing air contamination information gathered by EPA, state, neighbourhood, and innate air contamination control organizations from more than a great many screens. AQS likewise contains meteorological information, engaging data about each observing station (counting its geographic area and its administrator), and information quality affirmation/quality control data.

Mechanical fumes Emission of unsafe gases, for example, SO2 and NOx from warm power plants of different regions of the country and other modern locales adds to the real contaminations of the Delhi air contamination. Vehicular emanation Traffic clog and vehicular outflow contributes significantly to corrupting the Delhi air quality. The biggest number of the enrolled vehicles also contributes to the pollution. These are viewed as significant donors towards air contamination. Construction and demolition Continuous development and obliteration adding to expanded dimension of residue borne particulate issues noticeable all around and are, along these lines, considered dangerous. Other factors some factors that may by implication include in compounding air quality are finished – populace, street dust, smoke and so on.

Air contamination is always a vital hazard factor. This for various wellbeing conditions that has included different type of contaminations regarding respiration, lung malignancy and coronary illness as indicated by World Health Organization. This impacts of wellbeing has brought about via air contamination may incorporate trouble in breathing, wheezing, hacking, asthma furthermore, exacerbation of existing respiratory and cardiovascular conditions. The effects can result in the expanded medicine usage, various visits of specialists, more emergency clinic confirmations and Accidental death.

The effects of wellbeing of people has been of poor quality influencing the body of respiratory the framework and the system of cardiovascular. The different singular reactions towards the positions of air has been depending on various kinds of contamination over the human beings and present to the status of wellbeing and qualities that are hereditary. Here, the popular wellsprings of the particles of air contamination, nitrogen dioxide and ozone.

Dashboard: NO2 Highest Values by States

Both the open air and indoor contamination have resulted in about 3.3 million numbers of accidental deaths around the world. The young people who are matured under the five years living to create the nation has been seen as the defenceless population about the entire death that is inferable from the indoor side. Apart from this is the revealed by WHO that about two million people has been dying every year from causing specifically owing to the air contamination. This has been the 1.5 million of the overall deaths that is inferable from air contamination coming internally.

 The pollutant elements are released out in earth’s atmosphere from numerous sources and in different concentration, but the quality of the ambient air depends on the quantities of the pollutant elements concentration as well as the ability of atmosphere, either absorb or disperse the pollutants. In addition to that, from the analysis it is found that, most of the pollutants elements vary between a large range   of limits and does not have any significant correlation between each other.

Even though the air quality has been improved over the years with the reduced number of pollutant elements but the pollutants (Ozone, NO2, and SO2) retain a high AQI in the environment. Therefore, efforts like lesser use of fossil fuel, use lesser electricity, and other support measures in communities.

The measures of control taking place due to air pollution has been an important problem. It is the cause of aversion intercessions. This has been dependably a great way to control the contamination of air. The techniques of anticipation has been originating from laws of government and various distinct activities. Further, in various enormous sectors, the witnessing of the gear has been introduced at various types of focus over the city. It is pursued by the experts that they have been normally checking the air quality.

Besides, it is seen that the government throughout the world has been moving against the contamination through presenting the importance of effective power. Besides, some of them has been putting the resources to wind vitality and vitality that is sun based, same as he sustainable power source. This is to limit the consumption the fills of fossils that is overwhelming the contamination of air. Additionally, the governments has been constraining the companies to rousingly get dependent with the fabricating exercises. This is despite the reality that regardless they can result into contamination. Apart from this business has been fabricating more importance to the proficient autos that not been contaminating the previous.

Prevention at the individual level

 Encourage families to utilize the transport, train or bicycle when driving. On the off chance this will help in lessening vehicles on street and less exhaust.

Energy Use: use of the light, water, and woods must be used astutely. This is on the grounds that parcels of non-renewable energy sources are scorched to create power, thus on the off chance that reducing down the utilization, that will likewise reduce the measure of contamination.

Recycling and re-using things:  It has been limiting the dependence of developing new things.  This has been vital to fabricate various contaminations, such that events that have been re-using the things such as containers, papers, garments, shopping plastic packs can be useful.

Control gadgets:

Here, the accompanying elements has been used as the contamination of controlled gadgets by the transportation and industry gadgets. This has been obliterating contaminants and expelling them from the exhaust channel proper it is radiated to the air. In addition to that, the mechanical gatherers multi-cyclones can help.

Electrostatic precipitators: This is also denoted as the ESP, to collect the systems expelling elements from the streaming of gas like air. This is done with the help of power of the charge that is incired electrostatic. Moreover, electrostatic precipitators has been highly productive with different filtration gadgets. This has been negligibly obstructing the flow of gases. This is done through the gadgets, without much of a stretch that has been found to be evacuating the fine particulates. For example, the dust furthermore, that has been found be smoking the stream of air.

Bag houses: This is developed for dealing with the massive attacks of residue. This consists of dust channel, blower and channels of the cleaning system and the evacuation of the residue. This is determined from the cleaners of air that has been utilizing the channels for expelling the residue.

Particulate scrubbers:

Here, the wet scrubber is the kind of innovation dealing with contamination control. Here, the term indicates the assortment of gadgets using toxins from the heater pipe gas and again from various streams of gas. Under the wet scrubber, the dirtied stream of gas has been brought to contact with fluid of cleaning through showing that with the fluid. This is compelled through the fluid and other strategies of contacts foe evacuating the elements of the contamination.

Conclusion

Air pollution can have long haul and transient impact on the health of human beings. Further, it is seen that the elder and youths are getting influenced due to air contamination. Specifically, it has been affecting the upper respiratory diseases, susceptible reactions, migraines nose eye an along with some long haul cerebrum issues and lung diseases. Mechanical air contamination/pollution prevention by organizations have for the most part concentrated on waste decrease and sources and reusing.  Anticipating the air contamination within the organization fabricating forms consisting of the primary methodology. Then there is handling and cleaning, change to various advances that are non-dirtying along with materials, decreased in the age of discharges and the changing over dangerous side-effects. This is to non-compromising structures, and has been found to be endeavoured at this respect. The discontinuity of duties regarding mechanical air contamination is ended up being an extraordinary obstacle to advancing feasible administration of the earth. This has realized irreconcilable circumstance among different partners. A legitimate administration plan is along these lines a vital option for the executives of air contamination by enterprises.
