The United States is the world’s biggest consumer of air purification, and it is becoming a bigger and bigger source of pollution.
According to a study by Air Resources Board (ARB), the U.K., China, Russia, Germany and India have all reported increasing air pollution levels from the use of air-purifying devices.
Some of the countries where air purifying devices have become common include India, China, Germany, France, the United Kingdom and Brazil.
The devices are usually purchased at home or at pharmacies.
They contain a mixture of air, water and a small amount of pure water.
In many cases, they have a filter or membrane attached that prevents contaminants from entering the device, but they do not remove most harmful chemicals, like lead, sulfur dioxide, nitrogen dioxide and soot.
In India, the government is trying to set up a national research program to develop and test devices that are less toxic and less expensive to operate.
In Europe, air purificators have become popular among people living in the capital cities, especially in the northeast of Europe.
In recent years, more than 2.2 million people in France and 1.6 million in Italy have had air purifications.
In the United States, the use is increasing, particularly among the young, the elderly and people with asthma.
In 2014, the U:S.
Air Quality Index (U:QI) was 2.5 on a scale of 1 to 10.
In 2016, it was 5.4.
The AQI rose from 3.3 in 2015 to 4.4 in 2016.
In 2017, the AQI was 4.9.
The U:QP is a measure of air quality that measures levels of nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and particulate matter (PM2.5).
A 2017 study published in the Journal of the American Medical Association found that in New York City, residents living in areas with higher AQI levels had a higher incidence of respiratory illnesses, and respiratory illnesses were more likely among those who had been living near high concentrations of pollution for more than 30 years.
The study also found that a significant increase in exposure to lead was associated with elevated levels of asthma and other respiratory disorders, including chronic bronchitis, emphysema and chronic obstructive pulmonary disease.
A 2017 survey of people living near the polluted areas of the East River in Brooklyn found that one-third had developed asthma, and more than one-fifth had experienced a history of chronic bronchoalveolar disease.
The air pollution in the area is estimated to be more than three times the level found in the U.:QI’s historical average.
In New York, the city was ranked 10th for pollution in 2016 and 9th in 2017, according to a recent survey by the city’s Department of Environmental Protection.
Some residents of Brooklyn have been complaining about air pollution for years, and the area has seen its share of bad air events in recent years.
In November, the New York Daily News reported that the city had been warned by the World Health Organization to take precautions to prevent pollution from reaching parts of Manhattan.
The report noted that in some parts of the city, “pumping stations are overflowing with hazardous-materials and hazardous waste.”
On Sunday, the Environmental Protection Agency released a new set of air pollution standards.
It includes new rules that aim to limit the release of pollutants from older, larger power plants, to improve pollution control and improve public health.
According the EPA, it is important for people to stay inside, especially during these times of pollution, because they are more susceptible to asthma attacks, COPD, respiratory illnesses and heart attacks.
