Pollution in the Air
We frequently hear the term “air pollution.” Let’s have a look at what it signifies. The gases oxygen, nitrogen, carbon dioxide, argon, and others make up air. When chemicals, particles, or biological elements are introduced into this otherwise pristine environment, the air is said to be polluted. Humans may experience discomfort, sickness, or death as a result of these pollutants. Other living organisms, such as food crops, may also be harmed. Industrial emissions, automotive emissions, residential emissions, and other factors all contribute to air pollution.
Index of Air Quality
Another phrase, which is closely related to air pollution, requires clarification. This is referred to as the Air Quality Index. The term AQI is commonly used to describe how dirty the air is.
This index informs the public about how contaminated the air is right now. As the AQI rises, the population’s health deteriorates. The AQI is regarded as a globally recognized index. The majority of daily newspapers, radio, and television broadcasts will provide daily information regarding the level of pollution in the air at a specific location. They will also provide a comparison with other cities/locations so that one can determine which is the most polluted and which is the least polluted.
Air Pollution Reduction
Any government or controlling authority’s goal is to reduce air pollution. How can this be accomplished? A number of the elements that contribute to air pollution, as well as ways for purifying the air, are addressed here.
1) Automobile engines. Using cutting-edge technology is one way to reduce the AQI. Car engines are one of the most significant contributors of air pollution. Scientists have developed automotive engines that are significantly more efficient than in the past. Modern engines emit fewer pollutants and use less fuel, such as gasoline.
2) A catalytic converter is a device that converts one substance into another. Catalytic converters are a significant achievement in automotive technology. These are attached to the exhaust pipes of cars and can lower the quantity of hazardous carbon monoxide and nitrogen monoxide emitted. Toxins are converted into less hazardous compounds using catalytic converters. The emergence of electric-powered cars is another positive step for clean energy, but it may take another decade for them to gain widespread adoption.
3) Coal-fired and fossil-fuel-fired power plants. Coal and gas-fired power plants (fossil fuels) are another major cause of pollution. This is due to the fact that fossil fuels include small amounts of sulfur, which causes sulfur dioxide (SO2) to be created when they are burned, resulting in acid rain. To avoid this, a filter system was created that eliminates sulfur dioxide from waste gases produced during the plant’s operation.
4) Clean fuel technology development Engines that utilise hydrogen gas are being developed since the sole by-product of hydrogen is water, and such engines will be pollution-free. Newer renewable energy sources, such as wind, solar, and wave power, are on the horizon. Geothermal energy, biomass energy, and hydrogen are among the unconventional sources being tested.
5) Wind Power. The usage of wind energy is one of the most powerful technological advances. Wind is the movement of air that occurs when heated air rises and is replaced by cooler air. Sailing ships have exploited wind energy for ages. Modern wind turbines use the power of the wind to generate electricity.
6) Solar Energy/Sun. The sun is the second source of limitless energy. This technology is still in its infancy, yet it will become one of man’s most essential sources of energy in the coming years. Currently, solar energy is used for lighting, heating, and some industrial operations.
