FAQ: Study on dental floss and other behaviors associated with exposure to PFAS

We recently published a study in which we found an association between blood levels of PFAS (per- and polyfluoroalkyl substances) and different exposure-related behaviors, including flossing with certain dental flosses. We also tested some common brands of dental floss to see which ones are likely to be made with PTFE (a PFAS polymer also known as Teflon). PDF icon Download FAQ
Measurement of Endocrine Disrupting and Asthma-Associated Chemicals in Hair Products Used by Black Women

Overexposed and Underprotected

Black women spend upwards of 7.5 billion dollars on beauty products every year, spending nine times more on ethnic-targeted hair products than the average consumer. As the beauty industry grows in inclusiveness and diversity, more brands are creating products for Black women such as makeup lines and products for naturally curly hair. However, the chemicals in these and other personal care... PDF icon Download factsheet

Unsettling Dust: Toxic Chemicals on College Campuses

What are flame retardant chemicals? Until recently, manufacturers routinely added toxic flame retardant chemicals to furniture in order to meet flammability standards. Flame retardants are still added to textiles, electronics, children’s products, and building materials such as insulation. Although flame retardants are intended to prevent or slow the spread of fire, their effectiveness in... PDF icon Download fact sheet

Not Just Dirt: Toxic Chemicals in Indoor Dust

On average, people in the United States spend more than 90 percent of their time indoors—in places like homes, schools, offices, gyms, and cars. These places are usually full of dust, which is more than just dirt. Household items like televisions, furniture, beauty products, cleaning products, and flooring materials shed chemicals that end up in the air and in the dust on our floors. These...

Body Burden

The chemical burden we all carry from our increasingly polluted world continues to grow heavier. Not even the newest members of society are safe: One study found the umbilical cord blood of 10 newborns to contain an average of 200 contaminants—including a range of pesticides, flame retardants, and other pollutants—a chemical inheritance from time spent in the womb. link File test doc.docx
