Study finds deodorant can create indoor pollution similar to city smog
The study found the introduction of ozone, especially with products like perfumes and sprays, can create particles that rival those found in heavily polluted cities.
Researchers have found that common products like deodorants, perfumes, and hair sprays release a cocktail of over 200 volatile organic compounds into the air.
When exposed to ozone—a reactive gas that can enter homes through open windows— these compounds trigger chemical reactions that create new pollutants, but scientists are unsure how exposure affects our health.
The research was conducted in controlled environmental chambers, designed to simulate indoor conditions.
The study found the introduction of ozone, especially with products like perfumes and sprays, can create particles that rival those found in heavily polluted cities.
The study highlights the need for improved indoor ventilation and air purification to reduce exposure.
These findings appear in Environmental Science & Technology Letters.
