Which of the following are sources of air pollution?
a. Vehicles b. Dams
c. Oil Refineries d. Mining Industries
The correct option is D a, c and d
Vehicles are the main source of air pollution. Vehicle emissions can affect the environment in several ways. Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming. Some air pollutants and particulate matter from cars can be deposited on soil and surface water where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals. Oil refineries are factories where oil is made into gasoline and other fuels, and into materials such as asphalt and plastic. Oil refineries are a major source of air pollution for people who live near them and work there. Chemicals in and around refineries cause cancer, reproductive harm, breathing problems such as asthma and emphysema, and birth defects, as well as other health problems such as headaches, nausea, dizziness, and stress. Refineries are also a major source of the gases that cause global warming. Mining is a process wherein minerals below the earth are extracted using large equipments. During the process dust and chemicals are released in the air causing massive air pollution.
