QUES . What is pollution dome ? Discuss its formation and impacts.
HINTS:
A pollution dome, also known as an inversion layer, is a weather phenomenon that occurs when a layer of warm air sits on top of a layer of cooler air near the ground. This creates a “dome” of pollution that is trapped underneath the warm layer and cannot disperse. Pollution domes are commonly associated with urban areas and are known to have negative impacts on human health and the environment.

Formation of Pollution Dome
Pollution domes typically form during stable weather conditions, such as during high pressure systems or when there is a lack of wind. During these conditions, the ground cools more quickly than the air above it, creating a layer of cool air near the ground. If a layer of warm air moves in above the cool air, it acts like a lid, trapping the cool air and any pollutants that have been released into it. As more pollutants are emitted, the pollution dome becomes more concentrated.

Impacts of Pollution Dome
Health Impacts: Pollution domes can have serious impacts on human health, especially for those with respiratory problems like asthma. The trapped pollutants can lead to increased respiratory illnesses, eye irritation, and other health problems.

Environmental Impacts: Pollution domes can also have negative impacts on the environment, including acid rain, decreased visibility, and damage to crops and vegetation.
Economic Impacts: Pollution domes can also have economic impacts, such as decreased tourism and reduced property values in affected areas.

Traffic Disruption: The air trapped in the dome doesn’t move, and this often disrupts air traffic, especially in urban areas where there is a lot of traffic.

Formation of Smog: The pollution dome leads to the formation of smog, which can have serious impacts on human health, the environment, and the economy.
Must read: PARTICULATE MATTER AND ITS EFFECTS
In conclusion, pollution domes are a serious environmental and public health concern. To mitigate their effects, it is important to reduce the release of pollutants into the air and take measures to combat climate change, which can exacerbate the formation of pollution domes. Additionally, local governments and individuals can take steps to reduce their impact on air quality, such as limiting car use and properly disposing of hazardous materials.
