 What is AIR POLLUTION???      Air Pollution  is the contamination of the atmosphere with harmful substances that can adversely affect human health, ecosystems, and climate.   The contaminating substances that cause air pollution are called Air Pollutants.   These substances can be gases, particles, or a combination of both and come from various sources.   Air Pollution is one of the prominent types of Environmental Pollution. Which is called as AIR POLLUTANTS:      Air pollutants are harmful substances released into the atmosphere, causing damage to the environment and human health. These include  particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO 2 ), ozone (O 3 ),  and volatile organic compounds (VOCs). Main Causes of AIR POLLUTION: Vehicle emissions  – Exhaust from cars and trucks. Industrial activities  – Factories and power plants releasing pollutants. Bu...

POLLUTION...      Pollution is a state when an adverse change takes place in the natural environment due to the introduction of contaminants. It can be caused by a variety of chemical substances or energy like sound, light, or heat. Particulates like smoke, foreign particles and dust, and excess noise or heat, or sound are called pollutants. Pollutants cause disturbances not only in the environment but also in the living entities. These foreign bodies enter the human body via the food chain and also impact the ecological balance, even in tiny amounts. This paragraph on pollution is an answer to the definition of pollution. Different Types of Pollution        There may exist numerous causes of pollution for different types of pollution that include- Air Pollution Water Pollution Soil Pollution Noise Pollution      Besides, other types of pollution are thermal pollution, light pollution, and radioactive pollution.  Radioactive polluti...
