"Pollution control systems are a must. Air pollutants are generated through both natural--e.g., volcanic eruptions and wildfires--and human-made sources--including mobile and stationary ones. In high enough concentrations, the pollutants produced by either mobile or stationary sources could cause adverse effects to the atmosphere, the surrounding environment, human life, increasing the average global temperature, decreasing atmospheric visibility, diminishing air quality, and affecting human health. Air pollutants are generated by nearly every facet of the industrial process, including raw material sourcing, product manufacturing, maintenance and repair services, and distribution. Consequently, there are several different types of air pollution control equipment available for air pollutants produced by both mobile and stationary sources across a wide range of industries. In an industrial setting, air pollution control equipment is an umbrella term referring to equipment and systems used to regulate and eliminate the emission of potentially hazardous substances--including particulate matter and gases into the air, atmosphere, and surrounding environment."-- Provided by publisher.
