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.
The pollutants released into the atmosphere cause local air pollution (see Table of Common Pollutants). However, they also cause regional air pollution, as with huge plumes of smoke covering a large area, and acid rain.n some cases, air pollutants contribute to climate change, and greenhouse gases contribute to air pollution: 1  Air pollutants such as ground-level ozone and soot (a portion of particulate matter) contribute directly to global warming, which is linked to climate change.
