Explanation:


Flyash is a residue generated from the combustion of coal in thermal power plants. It is composed of fine, glassy, spherical particles that are primarily made up of silica, alumina, iron, and calcium. Flyash is a significant environmental pollutant that can cause a wide range of health and environmental problems.

Environmental Impact:


Flyash is one of the primary sources of air and water pollution. It is classified as a hazardous waste, and its disposal is a significant environmental challenge. When flyash is disposed of improperly, it can contaminate soil, groundwater, and surface water. Flyash contains heavy metals such as arsenic, lead, and mercury, which can cause various health problems in humans and animals.

Health Impact:


When flyash is inhaled, it can cause respiratory problems such as asthma, emphysema, and bronchitis. Long-term exposure to flyash can lead to lung cancer. Flyash can also cause skin irritation, eye irritation, and other health problems.

Preventive Measures:


To prevent flyash pollution, thermal power plants must install pollution control devices like electrostatic precipitators, fabric filters, and scrubbers. These devices can capture most of the flyash particles and reduce emissions significantly. Flyash can also be used in the manufacturing of cement, concrete, and other construction materials, reducing the amount of waste material that needs to be disposed of.

Conclusion:


Flyash is a significant environmental pollutant generated by thermal power plants. It can cause air and water pollution, as well as various health problems. To prevent flyash pollution, thermal power plants must install pollution control devices and find alternative uses for the waste material.
