What kind of air pollutant is asbestos?
Indoor Air Pollution – Asbestos. Asbestos is a mineral rock mined in much the same way as other minerals such as iron lead or copper(1). It exhibits substantial resistance to heat and deterioration and thus has historically been used for a variety of commercial and industrial purposes(1).

Radon gas which usually enters a home through the foundation can cause lung cancer. … Asbestos which is used in a vast number of products is primarily associated with parenchymal asbestosis pleural fibrosis mesothelioma and lung cancer.
Is asbestos an environmental pollutant?
Asbestos as a pollutant in the air may be a serious health problem globally similar to many other environmental pollutants [2 3 4 5 6].
Is asbestos a primary or secondary pollutant?
Primary Pollutants
Asbestos is six naturally occurring minerals (chrysotile tremolite anthophyllite amosite crocidolite and actinolite) each consisting of long thin fibrous crystals. … Asbestos is a primary pollutant which means that it is directly released into the atmosphere.
Is radon an indoor air pollutant?
Health Effects
Radon is a major source of indoor air pollution and is the cause of tens of thousands of deaths annually in the United States and Europe. … Radon and its daughters continue to decay in the lungs releasing alpha and beta particles that can damage cellular DNA and result in lung cancer.
What are the different types of pollution?
What are 5 indoor pollutants?
According to the Environmental Protection Agency the top five air quality problems in the U.S. are all indoor air problems. Common residential indoor pollutants include excessive moisture volatile organic compounds (VOCs) combustion products radon pesticides dust particles viruses and bacteria.
What are the 5 primary air pollutants and their sources?
The five primary air pollutants include carbon monoxide nitrogen oxides particulate matter sulfur oxides and volatile organic compounds. The sources for all five of these pollutants include electricity production industry and transportation.
What is the concern with pollution from carbon monoxide asbestos and lead?
Risks: In the long-term exposure to asbestos can lead to various lung disorders including lung cancer and asbestosis. Asbestosis is an inflammatory condition of the lungs that causes coughing trouble breathing and permanent lung damage.
What are the 6 criteria pollutants?
EPA has established national ambient air quality standards (NAAQS) for six of the most common air pollutants— carbon monoxide lead ground-level ozone particulate matter nitrogen dioxide and sulfur dioxide—known as “criteria” air pollutants (or simply “criteria pollutants”).
How is radon similar to asbestos?
Unlike asbestos radon is a gas and it has never been used in manufacturing. Instead radon occurs naturally around us. Radon is most commonly found in soils. Radon can also make its way into well water or surface water from the soil that surrounds it.
What do you do about radon?
- Seal and caulk foundation cracks and openings to help reduce the amount of radon that can enter.
- Install a soil suction radon reduction system also known as vent pipe and fan system. …
- Create a gas-permeable layer beneath the slab or flooring. …
- Install plastic sheeting.
What is mesothelioma caused by?
Asbestos exposure is the main cause of pleural mesothelioma. About 8 out of 10 people with mesothelioma have been exposed to asbestos. When asbestos fibers are breathed in they travel to the ends of small air passages and reach the pleura where they can cause inflammation and scarring.
Why is asbestos and environmental issues quizlet?
Asbestos is highly friable meaning that as it ages asbestos fibers break down easily into tiny filaments and particles. This makes asbestos especially harmful when it is disturbed or exposed and becomes airborne as often occurs during renovation or remodeling.
What are the effects of asbestos?
People with fully developed asbestosis have shortness of breath cough chest pain reduced lung function finger clubbing and bluish skin colouration. Development of asbestosis usually requires several years of exposure to asbestos fibres.
Where is asbestos in the environment?
Asbestos is also present in the environment naturally primarily in underground rock. In most areas asbestos fibers are not released into the air because the rock is too deep to be disturbed easily.
Is radon a secondary pollutant?
Radon perfumes noxious odors can also be considered pollutants. … Secondary – Formed when primary pollutants react or combine with one another or the basic elements.
What is primary pollution and secondary pollution?
Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such but forms when other pollutants (primary pollutants) react in the atmosphere.
Which is the secondary pollutant which influences air pollution?
Given that the ozone is cataloged as a secondary air pollutant its occurrence into the ambient air is due to chemical reactions among primary polluting compounds emitted directly from emission sources. Therefore its tropospheric formation is associated with anthropogenic and biogenic emissions [50].
How does radon become a pollutant?
Radon forms naturally. Uranium in soil or rock breaks down to form radium which then turns into radon gas. Once formed radon enters a home through cracks in walls basement floors foundations and other openings. As radon decays it releases radioactive byproducts that are inhaled and can cause lung cancer.
What is a source of radon that could lead to indoor air pollution?
The primary sources of indoor radon are analyzed and discussed. These include soil gas building materials and tap water. … In exceptional cases where radon sources are unusually strong radiation exposure from radon decay products may exceed the occupational standard for uranium miners.
What’s a source of radon that could lead to indoor air pollution?
The main source of indoor radon is the radon produced by the decay of radium in the soil subjacent to a house.
What are the 7 different types of pollution?

What is the major source of indoor air pollution?
Indoor air pollution may arise from the use of open fires unsafe fuels or combustion of biomass fuels coal and kerosene. Gas stoves or badly installed wood-burning units with poor ventilation and maintenance can increase the indoor levels of carbon monoxide nitrogen dioxide and particles.
