Part - 2 Types of air pollutants and effects Sulphur dioxide (SO2) Sulphur dioxide is a colourless gas, with a pungent, suffocating smell. It is produced by burning sulphur-containing fuels such as coal and oil. This includes vehicles, power generation and heating. Most sulphur dioxide comes from electric industries that burn fossil fuels, and from petrol refineries and cement manufacturing. It can travel over long distances and contributes to the formation of ozone. Effects of SO2 – Sulphur dioxide can irritate the lining of your nose, throat, and lungs. It can cause coughing and tightness of your chest, as well as a narrowing of your airway that will reduce the flow of air to your lungs. It inflames the airways, causing coughing and more mucus. It makes conditions like asthma and COPD worse and can lead to people being more prone to chest infections. #Airpollutants#Purifytheair# #4u4everReddySudarshan# https://www.instagram.com/p/CAcQDalHNKs/?igshid=ezv2b6ji90l

Part 1 Types of Air Pollutants and Effects particulate matter (PM) PM varies in size. Some particles, such as dust, soot, dirt, or smoke are large or dark enough to be seen with the naked eye. But the most damaging particles are the smaller particles, known as PM10 and PM2.5. PM10 refers to particles with a diameter smaller than 10 microns (10µm) – that is 100 times smaller than a millimetre. PM2.5 refers to particles with a diameter smaller than 2.5 microns, and these are known as fine particles. The smallest fine particles, less than 0.1 micron in diameter, are called ultrafine particles. Effects of PM – The size of particulate matter will determine where it will end up once you breathe it in. Larger particles may be trapped in your nose, while PM10 can reach your airways. Fine particles (PM2.5) may reach the breathing sacs deep in your lungs, and ultrafine particles may even cross into your blood stream. These particles can also carry toxic chemicals that are linked to cancer. Nitrogen dioxide (NO2) Nitrogen dioxide is a gas and is a major component of urban air pollution episodes. Man-made sources of nitrogen oxides, including nitrogen dioxide, are vehicles, power stations and heating. Diesel vehicles are major contributors in urban areas. Roadside levels are highest where traffic is busiest. Effects of NO 2 High levels of NO2 can irritate and inflame the lining of your airways, causing a flare-up of asthma or COPD and symptoms such as coughing and difficulty breathing. Ozone (O3) Ozone is a gas composed of 3 atoms of oxygen. In the upper level of the Earth’s atmosphere, it absorbs harmful ultraviolet radiation.Near the ground, ozone is made by a chemical reaction between the sun’s rays and organic gases and oxides of nitrogen emitted by cars, power plants, chemical plants, and other sources. Effects of O3 – Ozone can irritate the airways of both healthy people and those with lung conditions. High levels can cause discomfort when you breathe, reduce your lung capacity (the amount of air your lungs can hold) and trigger asthma symptoms. #Airpollutants#Purifytheair# #4u4everReddySudarshan# https://www.instagram.com/p/CAcP6mmHQHU/?igshid=rv4tv3fw6gmi
