ABSTRACT
The air quality of Chandigarh city is assessed by using air quality index (AQI). The main component of pollution in the city is suspended particulate matter. The study shows that air pollution is rising again in the city. The air quality in the city can be characterised as bad and on critical lines by air quality index used. This can be attributed to increasing vehicular density which ultimately results to higher vehicular emissions and so does the pollution. Also, the role of meteorological conditions in dispersion of pollutants is also discussed with the help of trend analysis technique.
INTRODUCTION
The World Health Organization estimates that air pollution contributes to approximately 800,000 deaths and 4.6 million lose their life years annually [10]. Developing nations are particularly affected by air pollution; as many as two thirds of the deaths and lost life years associated with air pollution on a global scale occur in Asia [11]. The data available from the Environment information system (ENVIS) centre indicates that the levels of small particles less than 10 micron (PM10) are showing sharp rising trends in the Indian cities. According to the UN agency’s latest pollution data, Delhi (not Beijing) tops the list of most polluted cities. Among the world’s 20 most polluted cities in the world, 13 are in India. India is in the group of countries that has the highest particulate matter (PM) levels. Its cities have the highest levels of PM10 and PM2.5 (particles
The Bronx is an incredibly urban and populated area attracting traffic from all over. It is home to waste sites, distribution centers, power plants, and so much more. Though each building gives off a different type of waste, whether it be smog from smokestacks or diesel exhaust from trucks, each of these large sites that exist throughout this small area give off a fine particulate matter known as PM2.5. This matter is essentially what contributes to the difficulty breathing people experience as these tiny particles can become lodged in a person’s lungs over time. Studies have consistently found a strong correlation between PM2.5 and conditions like asthma, lung disease, and heart disease.
Air quality is known to be a key factor in affecting the wellbeing and quality of life of the general populous and there is a large body of knowledge indicating that certain underrepresented groups may be overexposed to air pollution. (Zou et al. 2014). This is an example of the air quality in locations with a lower known location that is associated with poor air
Air pollutions rapid increase is not without our help, many causes and sources of this problem are attributed to
Air pollution is believed to contribute to numerous deaths through the augmentation of various illnesses. Close vicinity to areas which receive a highly concentrated amount of traffic results in a 20 percent decreased lung size in children than average, which initiates respiratory dysfunction. The exhaust emitted from trucks causes the quality of air to immediately rise to a point that is 4,000 times as polluted with “particulate matter” as is considered suitable for a person’s health.
Residents of the border are exposed to air pollution from an assortment of sources, one including automobiles and industries. Pollutants such as sulfur dioxide and carbon monoxide raise concerns of health for the residents of the border region. Thermoelectric plants and smelters are known to release sulfur dioxide into the air, causing problems for residents. Several of the border cities are facing major air pollution problems associated with the increase of numbers and the usage of truck and automobiles
Some cities in china have everyone wear gas masks when they go outside. That 's just tragic! Can you imagine getting lung cancer for standing outside for 10 minutes? Cars can release 2 different kinds of pollution. There is primary pollution that goes straight into the air to pollute it and secondary pollution.
Along with food, water, and shelter, the air we breathe is essential to life. If we do not have clean air to breathe, we will become ill and even die. If we do not prioritize the air we breathe, the pollution tragedies such as what happened in Delhi last November 2016 and the Southern Plains during the Dust Bowl of the 1930s will strike again. Humans’ indifference, attempts to improve their life, or both. Sometimes when people try to improve human life, they end up harming it; in finding solutions to these man-made problems, we must consider short and long term solutions.
In Some parts of north america, air pollution is so high that if you breathe the air for a period of time it can cause severe damage and sometimes death. In the U.S air pollution causes as much as 50,000 deaths per year. For example, currently in Spokane the AQI can problems for people with lung problems. In Fresno and Madera the pollution over time can increase the risk of asthma, heart disease, COPD(Chronic obstructive pulmonary disease), and diabetes. Even in most urban areas the amount of air pollution increases the chance of getting strokes, heart disease, lung cancer, and chronic/acute respiratory diseases.
1. Introduction Air pollutin is a public health concern and it has been since the discovery of fire. Incidents and episodes of air pollution have been recorded throughout the history. Air pollution is divided into two, it is the indoor air pollution and the outdoor air pollution. Indoor air pollution is produced in households or at offices by pollutants such as tobacco smoke, household products or pesticides.

Recently, air pollution has been changed since 1950s, Firstly in 1950s, air pollution was visible and mostly caused by factories. Now, air pollution has become invisible because of the cars and vehicle pollution. The main reason for this rising problem is because people are vehicle independent. In conclusion, governments should take actions to this urgent issue which risks to people 's health.
As of November of 2017, Delhi, India, was the most polluted city on the planet. In 2015, nine million people died from pollution, and in India alone, two and a half million people died. The World Health Organization stated that air pollution will continue to harm and kill many people around the world, and of course India, for many years, with poorer countries being affected the most (Irfan).
b. Credibility: Air is a necessity to be able to live. But today air becomes an element to kill us slowly. Air pollution is a major problem in the world yet it is not given enough attention to. Cities have higher air pollution compared to provinces because of the inevitable huge number of vehicles and heavily congested areas. According to Eva Ocfemia, the assistant director of the DENR-EMB in 2015, the air pollutant concentration of NCR reached 130 micrograms per cubic meters in terms of total suspended particulates (TSP), higher than the previous year and the safe level.
Particulate matter is a complex combination of fine solid particles and liquid droplets comprising various types of dust, smoke, and soot, gaseous and biological contaminants that are suspended in air. The size of these particles ranges from few nanometers to around 100 micrometers. Mainly, coarser particulate matter PM10 with diameter less than equal to10 micrometers and fine particulate matter PM2.5 with diameters less than equal to 2.5 micrometers are significant. Particulate matter in air comes from both natural sources such as wildfires and dust storms and anthropogenic sources like power and industrial plants, fossil fuel burning, combustion of wood and other biomass fuels and automobiles. In Urban areas, vehicular traffic is one of the major sources of particulate matter pollution.
There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.
