So, they reassessed urban pollution sources by cataloging chemical production statistics, evaluating indoor air quality measurements made by others and then determining if the new information filled the gap.

"People use a lot more fuel than they do petroleum based compounds in chemical products-about 15 times more by weight, according to the new assessment". The results were published on February 16 in the journal Science.

"The use of these products emits VOCs in a magnitude that's comparable to what comes out of the tailpipe of your auto", said study lead author Brian McDonald.

"What's exciting about this work is that it shows that everyday consumer choices can have an impact on air quality in the USA", said Christopher Cappa, professor of civil and environmental engineering at UCD and a co-author on the paper.

Experts advise consumers to use smallest amount possible to get the job done stating that cleaning and beauty products release compounds that react in the air to produce particles known as PM2.5.

City dwellers assume that much of the pollution they breathe comes from vehicle emissions or leaky gas pumps.

The study's results highlight a new problem that nations will have to face which is that as auto emissions drop, governments will have to start tackling the increasing dangers associated with indoor air pollution. They also made detailed atmospheric-chemistry measurements in Los Angeles air and analyzed indoor air quality measurements made by others.

The results revealed that rather than the split of air pollution sources being 75/25 it was far closer to 50/50.

The EPA estimates that about 75 percent of VOC emissions come from fuel-related sources and about 25 percent come from chemical products.

Consumer products are created to release VOCs into the air, noted study team member Jessica Gilman, a research chemist with the NOAA's Chemical Sciences Division. Cut back on using the most common culprits and as recommended by Jessica Gilman, of the US National Oceanic and Atmospheric Administration, use unscented products. You wear perfume or use scented products so that you or your neighbour can enjoy the aroma.

Last year, in October, a study by global medical journal "The Lancet", said that in 2015, pollution was the reason behind nine million deaths worldwide-or about one in six. The report ranked "ambient particulate matter pollution" as the largest air pollution risk. "We had to collect an overwhelming amount of evidence to say that these sources are important", says McDonald. The researchers also estimated the proportion of volatile organic compounds from products such as soaps and cleaners that ends up in the air, as opposed to being washed down the drain.

"They also determined that people are exposed to very high concentrations of volatile compounds indoors, which are more concentrated inside than out".
