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.
Lesson Summary. Indoor air pollution is when pollutants contaminate air indoors and is a very dangerous problem, claiming more than 2 million lives each year.
