What is the PEL for SO2?
5 ppm
OSHA: The legal airborne permissible exposure limit (PEL) is 5 ppm averaged over an 8-hour workshift.
What is the major source of sulfur dioxide emissions?
The largest sources of SO2 emissions are from fossil fuel combustion at power plants andother industrial facilities.
What are three sources of sulfur dioxide emissions?
These gases, especially SO2, are emitted by the burning of fossil fuels — coal, oil, and diesel — or other materials that contain sulfur. Sources include power plants, metals processing and smelting facilities, and vehicles.
What is the major source of sulfur dioxide in Alberta?
The two largest sources of man-made SO2 in Alberta are the upstream oil and gas industry and coal-fired electricity generation.
How does sulfur dioxide affect the environment?
Environmental effects When sulfur dioxide combines with water and air, it forms sulfuric acid, which is the main component of acid rain. Acid rain can: cause deforestation. acidify waterways to the detriment of aquatic life.
Who is most at risk of sulfur dioxide exposure?
People sensitive to sulfur dioxide include: People with lung diseases, such as asthma, chronic bronchitis, and emphysema will generally have more serious health effects at higher SO2 levels. Children are at higher risk from SO2 exposure because their lungs are still developing.
Which disease is caused due to sulfur dioxide?
Sulphur dioxide can cause respiratory problems such as bronchitis, and can irritate your nose, throat and lungs. It may cause coughing, wheezing, phlegm and asthma attacks. The effects are worse when you are exercising. Sulphur dioxide has been linked to cardiovascular disease.
What are the primary sources of sulfur dioxide as air pollution?
The main sources of SO2 emissions are from fossil fuel combustion at power plants, refineries, and other industrial facilities. Secondary sources of SO2 emissions include ore smelters and the burning of high sulfur fuel by trains, large ships, and non-road equipment.
How can I lower my so2 emissions?
Reducing Pollution One option is to use coal that contains less sulfur. Another option is to “wash” the coal to remove some of the sulfur. The power plant can also install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack.
How does Sulphur dioxide affect animals?
At the ecosystem level, sulfur dioxide affects species composition by eliminating more sensitive species. This reduces primary productivity and alters trophic relationships which have far‐reaching implications for the animal and microbial populations in the community.
Why Sulphur dioxide is a pollutant?
Sulphur dioxide (SO2 expressed as SOx) has long been recognized as a pollutant because of its role, along with particulate matter, in forming winter-time smog. Studies indicate that SO2 causes nerve stimulation in the lining of the nose and throat.
How is Sulphur dioxide an air pollutant?
Sulfur dioxide (SO2) is a gaseous air pollutant composed of sulfur and oxygen. SO2 forms when sulfur-containing fuel such as coal, oil, or diesel is burned. Sulfur dioxide also converts in the atmosphere to sulfates, a major part of fine particle pollution in the eastern U.S.
Can a hazcard be used for anything other than science?
Hazcards However, they have been simplified, reorganised and expanded to cover some non-chemical hazards and situations other than those found in school science. In addition, some guidance is given on how pupils might assess risks involved in practical activities. Although most of the
