A new study published in the journal Science states that scented everyday products, such as shampoos, perfumes, and cleaning products, have the same impact on air pollution as automobile emissions. The US National Oceans and Atmosphere According to the research led by the Bureau of Administration, people use petroleum as their fuel in their daily lives 15 times as much as their chemicals. However, the amount of chemical gases released into the atmosphere through fragrance products is roughly the same as the amount of fuel they emit. These chemical gases are mainly volatile organic compounds (VOCs). They react with sunlight to form ozone pollution and also react with various chemical substances in the atmosphere to produce particles.
Using Los Angeles as an example, the researchers sorted out recent chemical production statistics and reassessed the sources of air pollution. They found that the volatile organic compounds emitted by chemical products are two to three times higher than previous estimates. This also means that The previous data overestimated vehicle emissions. For example, the Environmental Protection Agency estimated that about 75% of VOC emissions come from vehicles, and about 25% come from chemical products; and this new study shows that the latter is close to 50 %.
One of the research chiefs, Jessica Gilman, atmospheric scientist at the National Oceanic and Atmospheric Administration of the United States, explained that fuels such as gasoline are generally stored in closed, sturdy containers and burned to obtain energy. However, Volatile chemical products used in common solvents and personal care products actually evaporate. The results show that people can now not only influence the air quality by restricting the transport. Research another person in charge, University of California, David Christopher Cappa, a professor of civil and environmental engineering at UCSC, said that this will change the choices of everyday consumers.
