Plastics industry.
For processes where plastic are molded or extruded sub-micron and oil mists are genetared. Certain other process like fiberglass reinforced plastic equipment fabrication emits voc.
Power industry.
Power generators are starting to become as heavily regulated as industrial facilities due to the sheer volume of pollutants emitted by a power plant. While coal is relatively inexpensive and abundant, coal-fired boilers are single largest point source of pollution, giving out large particulate, PM10, SO2, SO3, PM2.5, mists, metals and mercury particulates.
What are the effects of air pollution?.
Air pollution affects every living species living in an air-polluted environment. It also effects the environment in more then one way.
Particulate Pollution.
Health Effects.
Particulate air pollution is a complex mixture of small and large particles of varying origin and chemical composition. Larger particles, ranging from about 2.5 microns to 100 microns in diameter, usually comprise smoke and dust from industrial processes, agriculture, construction, and road traffic, as well as plant pollen and other natural sources. Smaller particles include soot from vehicle exhaust, which is often coated with various chemical contaminants or metals, and fine sulphate and nitrate aerosols that form when so2 and nitrogen oxides condense in the atmosphere. The largest source of fine particles is coal-fired power plants, but auto and diesel exhaust are also prime contributors, especially along busy transportation corridors.
The health effects of particulates are strongly linked to particle size. Small particles, such as those from fossil fuel combustion, are likely to be most dangerous, because they can be inhaled deeply into the lungs, settling in areas where the body's natural clearance mechanisms can't remove them. The constituents in small particulates also tend to be more chemically active and may be acidic as well and therefore more damaging.
