What Types Of Air Pollutants Are Commonly Found In Delhi’s Air?
Air pollution in Delhi, India is a serious public health concern. The city’s air quality is often ranked among the worst in the world, and exposure to high levels of air pollution can have significant negative impacts on human health.
There are several types of air pollutants that are commonly present in Delhi’s air. These include:
1. Particulate matter (PM): PM refers to tiny particles of solid or liquid matter that are present in the air and can be inhaled. PM can be made up of a variety of materials, including dust, dirt, soot, and smoke and can have a range of sizes, from visible to ultra-fine. PM in Delhi’s air is often concentrated during the winter months, when the burning of agricultural waste and coal for heating exacerbates the problem.
2. Oxides of nitrogen (NOx): NOx are a group of highly reactive gases that are produced when fossil fuels are burned. These gases include nitric oxide (NO) and nitrogen dioxide (NO2). NOx in Delhi’s air is primarily produced by vehicles, particularly diesel-powered vehicles, and by industrial sources. NOx can contribute to the formation of ground level ozone, which is another harmful air pollutant.
3. Sulfur dioxide (SO2): SO2 is a gas that is produced when fossil fuels are burned. It is a highly reactive gas that can contribute to the formation of ground level ozone and can also have direct impacts on human health. SO2 in Delhi’s air is primarily produced by vehicles and industrial sources.
4. Carbon monoxide (CO): CO is a colorless, odorless gas that is produced when fossil fuels are burned. It is a highly toxic gas that can have serious impacts on human health, particularly if it is inhaled in high concentrations. CO in Delhi’s air is primarily produced by vehicles and industrial sources.
How Do Air Purifiers Work To Remove Air Pollutants?
Air purifiers are devices that are designed to clean the air and remove pollutants, allergens, and odors. They work by drawing air into the device, passing it through a filter or a series of filters, and then releasing the air back into the room.
There are several different types of air purifiers, and each one works in a different way to remove pollutants from the air. Some types of air purifiers use electrostatic technology, which involves charging the air particles and then collecting them on a charged plate. Others use HEPA filters, which are high-efficiency particulate air filters that remove 99.97% of particles as small as 0.3 microns from the air.
Activated carbon filters are also commonly used in air purifiers. These filters work by adsorbing pollutants from the air, causing them to stick to the surface of the filter. The filters are then replaced or cleaned regularly to remove the adsorbed pollutants.
Ultraviolet (UV) air purifiers use UV light to kill bacteria and viruses in the air. This type of air purifier is often used in hospitals and other healthcare settings to help reduce the spread of infections.
Overall, air purifiers are effective at removing a wide range of pollutants from the air, including dust, pollen, mold spores, smoke, and pet dander. They can help improve air quality and make it easier for people to breathe comfortably.
