New research shows floor linings have less impact on air quality than other materials
A new study suggests that floor linins can reduce the amount of nitrogen dioxide and other pollutants in the atmosphere and reduce the number of days that residents experience air quality issues.
A study of more than 300 million air samples collected at about 200 US power plants found that only about half of the samples were found to contain detectable levels of nitrogen oxide and that the remaining samples had relatively low levels of other pollutants, according to a study published Tuesday in the journal Environmental Science and Technology.
“We are still looking at how well the new materials are able to reduce nitrogen dioxide,” said study lead author Mark B. Smith, an assistant professor of atmospheric science at Purdue University.
Nitrogen dioxide is a greenhouse gas that is produced by burning fossil fuels.
It is a powerful greenhouse gas and can cause a number of health problems.
It can cause respiratory problems, increase the risk of heart attacks and strokes and worsen asthma attacks.
In some people, exposure to higher levels of nitrous oxide can cause lung damage and damage the respiratory system.
The study included air samples from more than 400 power plants across the country, from plants that use natural gas to those that rely on coal.
It found that nitrogen oxide levels in the samples varied depending on the type of power plant and the types of materials used to manufacture them.
The study found that the nitrogen oxide concentration in samples of coal-fired power plants was significantly higher than in other materials tested.
The researchers also found that, on average, the nitrogen dioxide concentration of samples made of natural gas, compared with those made of coal, was less than that of samples of synthetic materials such as fiberglass or polycarbonate.
They also found no differences in the levels of ozone, carbon monoxide or carbon dioxide in natural gas and synthetic materials.
The findings are the first to examine the effectiveness of a variety of new materials, including carbon nanotubes and glass fiber, that are widely used in consumer products, such as carpeting and floor linens.
The research was funded by the National Science Foundation and the Air Resources Board.
It was presented Tuesday at the American Chemical Society’s annual meeting in Washington.
The American Clean Air Act requires manufacturers to disclose the type and amount of pollutants they are using.
The EPA, the nation’s largest air regulator, requires that all new materials be tested and that any pollutants identified as harmful or unacceptable be removed or reduced.
The EPA does not require new materials to be tested for their ability to reduce the concentration of pollutants in ambient air, but the agency has a policy that prohibits materials that have been tested to reduce nitrous oxides or other pollutants from being used in commercial buildings.
