Products like shampoo, cleaning products and perfume all contain volatile organic compounds or VOCs that slowly leak out and contribute to the ozone and help create a bigger air pollution issue than road vehicles do. In 2019, recent research findings were discussed in the AAAS Annual Meeting in Washington, D.C. about households and air quality. A main aspect looked at was how everyday tasks like cooking and cleaning impacted the air indoors. The HOMEChem field campaign conducted in 1018 monitored the indoor air quality of a home in Austin Texas. The scientists completed various household activities for a month and kept a log of the findings from testing conducted. They found that homes should be well ventilated because even simple tasks like boiling water had high levels of pollutants entering the air which can have negative health impacts. The findings were much higher than anticipated so the team was forced to recalibrate many of the measuring instruments. Indoor and outdoor air pollution experts have started coming together to research how pollutants have increased. Studies found that regulations on automobiles has decreased those emissions but household chemical pollutants have risen. This has caused scientists to focus on how home pollutants are impacting the air and how that impacts the people breathing it. The recommendation is for better ventilation and air purification units to be used in homes to help slow down the pollution.
