Understanding the difference between good air quality and bad air quality is essential these days. Being aware whether the air you’re breathing is bad for your health will help you take necessary precautions and keep you safe from any health issues.
Breathing polluted air puts you at a higher risk for asthma and other respiratory diseases. Pollution can also potentially damage the immune system, endocrine, and reproductive systems.
Air pollution can be defined as the presence of toxic chemicals or compounds present in the air which lower the quality of the air or cause detrimental changes to the quality of life.
Air quality index (AQI) is a numerical scale used for reporting day to day air quality with regard to human health and the environment. An increase in air quality index signifies increased air pollution and severe threats to human health.
0-50 : Good
51-100 : Moderate
101-200 : Poor
201-300 : Unhealthy
301-400 : Severe
401-500+ : Hazardous
We believe good air quality is fundamental to our well being. On average, a person inhales about 14,000 litres of air every day, and the presence of contaminants in this air can adversely affect people’s health.
The contamination of the surrounding environment by the addition of foreign/unwanted substances is known as pollution and anything which makes the surrounding environment unhealthy/unfit for the living is known as the pollution.
Smoke from vehicles, chimneys, industries, burning of wood, plastic, coal, natural gas etc which causes the release of harmful toxic gases such as carbon monoxide, sulphur dioxide, nitrogen oxides etc in the environment. Ground level ozone and particulate matter are also the major reasons for air pollution. Even there are some natural causes as well which add more to pollution like forest fires, volcanic eruptions, and methane from the swamps are some of the natural occurrences which add more to the pollution.
Pollution causes adverse effects on the environment and in turn to the living beings which are a part of the environment only. Air Pollution is posing a serious threat to both flora and fauna. Incurable respiratory diseases among animals, aorist rainfall, acid rain, global warming, depletion of ozone layer, the rise in temperature, withering of plants, drought-like conditions, the grimy appearance of buildings etc. are only because of air pollution.
The most abundant and harmful pollutants present in the air are particulate matter (PM 2.5 and PM 10), nitrogen dioxide, ozone, and sulphur dioxide.
Particulate matter such as PM10, PM2.5, PM1, and PM0.1 is defined as the fraction of particles with an aerodynamic diameter smaller than respectively 10, 2.5, 1 and 0.1 µm (for your information: 1 µm = 1 millionth of a meter or 1 thousandth of a millimeter.)
AQI India is the first ever pollution control platform in India consistently working on ways to educate people with solutions that can lessen the impact of the impending disaster.
The number in the AQI India map shows the real-time air quality index of the particular location.
Our monitoring device can detect invisible air particulate as small as PM 2.5 along with PM 10, temperature, humidity, and noise pollution. The sensors also retrieve complex data with the help of a camera that visualizes air pollutants of different forms like HCHO, No2, So2, O3, CO, and Co2.
AQI India monitor promises to provide real-time data of the air quality index that helps the user to gauge the quality of the air they are breathing along with precautionary measures.
We aim to cover every corner of the country by installing one monitor within the range of 2-3 km between each of them.
Mentioned below are some major pollutants are constantly contributing to the air pollution which is a real public health and environmental problem that can lead to among other things like global warming, acid rain, and the deterioration of the ozone layer.
Pollutants | Sources | Effects |
Ozone: Ozone is a molecule made up of three oxygen atoms which are naturally formed by the photolysis of normal oxygen by ultraviolet solar radiation at wavelengths below 242.5 nm in the stratosphere. | Ozone is not created directly, but is formed when nitrogen oxides and volatile organic compounds mix in sunlight. | Ozone can lead to more frequent asthma attacks in people who have asthma and can cause sore throats, coughs, and breathing difficulty. |
Carbon Monoxide: It is a gas that comes from the burning of fossil fuels, mostly in cars. | Carbon monoxide is released when engines burn fossil fuels. Emissions are higher when engines are not tuned properly, and when fuel is not completely burned. Cars emit a lot of the carbon monoxide found outdoors. | Carbon monoxide makes it hard for body parts to get the oxygen they need to run correctly. Exposure to carbon monoxide makes people feel dizzy and tired and gives them headaches. |
Nitrogen Dioxide: It is a reddish-brown gas that comes from the burning of fossil fuels. | Nitrogen dioxide mostly comes from power plants and cars. | High levels of nitrogen dioxide exposure can give people coughs and can make them feel short of breath. |
Sulfur Dioxide: It is a corrosive gas that cannot be seen or smelled at low levels but can have a “rotten egg†smell at high levels. | Sulfur dioxide mostly comes from the burning of coal or oil in power plants. It also comes from factories that make chemicals, paper, or fuel. | Sulfur dioxide exposure can affect people who have asthma or emphysema by making it more difficult for them to breathe. It can also irritate people's eyes, noses, and throats. |
Greenhouse Gases: Gases that stay in the air for a long time and warm up the planet by trapping sunlight. This is called the “greenhouse effect†because the gases act like the glass in a greenhouse. | Carbon dioxide is the most important greenhouse gas. It comes from the burning of fossil fuels in cars, power plants, houses, and industry. Methane is released during the processing of fossil fuels, and also comes from natural sources like cows and rice paddies. | The greenhouse effect can lead to changes in the climate of the planet. Some of these changes might include more temperature extremes, higher sea levels, changes in forest composition, and damage to land near the coast. |
Particulate Matter: Solid or liquid matter that is suspended in the air. | Particulate matter can be divided into two types-coarse particles and fine particles. Coarse particles are formed from sources like road dust, sea spray, and construction. Fine particles are formed when fuel is burned in automobiles and power plants. | Particulate matter that is small enough can enter the lungs and cause health problems. Some of these problems include more frequent asthma attacks, respiratory problems, and premature death. |
Particulate matter 2.5 (PM2.5), refers to tiny particles or droplets in the air that are two and one-half microns or less in width. The difference between PM10 and PM2.5 is only the size. Both PM 2.5 and PM 10 both are serious health concern since smaller particles can travel more deeply into our lungs and cause more harmful effects.
The motor vehicle engine emits many types of pollutants including nitrogen oxides (NOx), volatile organic compounds (VOCs), carbon monoxide (CO), carbon dioxide (CO2), particulates, sulphur dioxide (SO2) and lead. These ingredients create an urban smog which has the capacity to irritate pose the most serious threat to human health by penetrating deep into the lungs. Vehicular pollutants can cause lung irritation and weaken the body's defenses against respiratory infections such as pneumonia and influenza.
Even healthy people can experience health impacts from the polluted air including respiratory irritation or breathing difficulties during exercise or outdoor activities. High air pollution levels can cause immediate health problems including, aggravated cardiovascular and respiratory illness, added stress to heart and lungs, which must work harder to supply the body with oxygen and damaged cells in the respiratory system.
