Some chemical engineers, known as process engineers, specialize in a particular process, such as oxidation (a reaction of oxygen with chemicals to make other chemicals) or polymerization (making plastics and resins).
Quick Answer. Some of the major causes of air pollution include burning of fossil fuels, agricultural activities, exhaust from industries, vehicle fumes, mining operations and indoor pollutants. Air pollution has a negative impact on the environment and life in general.
Air Pollution. Air pollution consists of solid particles and gases. Many pollutants are carcinogens. People who breathe in these poisons are at a higher risk for asthma and reproductive-system damage.
