Air pollution in cities is a major health concern, especially due to airborne nanoparticles called aerosols. A large part of these particles doesn’t come directly from emissions but is formed in the air through chemical reactions. These reactions often involve gases released by everyday activities. While pollution from cars has decreased thanks to regulations, levels of harmful ozone and aerosol particles in cities remain high.


This study looks beyond cars and focuses on other rising sources of pollution, such as cooking and household products like cleaners, paints, and personal care items, collectively known as volatile chemical products (VCPs). In a comprehensive experiment, scientists recreated city air pollution in an outdoor simulation chamber using real-world chemical mixtures from gasoline, diesel, cooking, and VCPs. By analyzing these mixtures with advanced instruments, they found that one group of chemicals—monoterpenes from VCPs—played the biggest role in forming secondary organic aerosol (SOA), the harmful particles that affect air quality. In contrast, traffic and cooking had a much smaller effect.


As cities move away from fossil-fueled vehicles, VCP emissions are likely to become even more important. The study suggests that future air quality strategies should focus on reducing these emissions to improve urban air quality.
