In heavily polluted areas, we all know that we should try to avoid inhaling whatever toxins are floating around as much as possible. That’s why when pollution gets especially bad in China, people are advised to stay indoors, and it’s one of the reasons behind the rise in surgical masks being worn in Tokyo, Japan.
But a new study has found that when it comes to certain airborne pollutants, called phthalates, our skin can absorb just as much as we’re breathing in. “We’re big sponges for these chemicals,” lead researcher, John Kissel from the University of Washington in the US, told Science News.
Phthalates are a group of ‘semi-volatile’ chemicals that are used to make plastic soft and flexible, or as dissolving agents for other types of materials, and are found in all kinds of cosmetics, fragrances, and household cleaners. Derived from oil, around 2 million tonnes of phthalates are produced across the world each year, and more than 20 different types are in common use.
