Air Pollution: You Are Inhaling Hazardous Substances With Every Breath; Details

In Delhi, harmful pollutants like PM2.5, PM10 and gases such as nitrogen dioxide (NO2) are prevalent, especially during winter. These fine particles, mainly from vehicle emissions, industrial activity and crop burning, pose significant health risks, causing respiratory issues, heart disease and aggravating pre-existing conditions. According to aqicn.org, these are the pollutants found in the National Capital.

PM2.5 refers to fine particulate matter smaller than 2.5 micrometers, which can penetrate deep into the lungs and bloodstream, causing serious health problems like respiratory and cardiovascular diseases.

PM10 refers to particulate matter with a diameter of 10 micrometers or less. These particles can be inhaled into the lungs, causing respiratory issues, allergies, and worsening heart conditions.

Ozone (O3) is a gas composed of three oxygen molecules. While it protects the Earth from harmful UV radiation in the upper atmosphere ground-level ozone is a harmful air pollutant, causing respiratory problems and aggravating conditions like asthma. It forms when pollutants from vehicles and industries react with sunlight.

 

Nitrogen dioxide (NO2) is a harmful gas produced by vehicle emissions, industrial processes and power plants. It contributes to air pollution, leading to respiratory issues, asthma, and environmental damage like acid rain.

Sulfur dioxide (SO2) is a toxic gas produced by burning fossil fuels, industrial activities and volcanic eruptions. It can cause respiratory problems, aggravate asthma and contribute to acid rain formation.

Carbon monoxide (CO) is a colorless, odorless gas produced by incomplete combustion of fossil fuels. It can cause headaches, dizziness, and even death, especially in poorly ventilated areas. (Images: ANI)
