Conducted by researchers at Boston University’s School of Public Health, the study focuses on the presence of flame retardant chemicals in people. It is the first to find a link between household dust and exposure to such chemicals. Because young children tend to spend time on the floor, where dust is especially concentrated, they are more likely to come in contact with toxic particles.

These chemicals, known as polybrominated diphenyl ethers, or PBDEs, have been utilized in the U.S. since the 1970s. Found in an array of products ranging from TVs and computer wire insulation to mattresses and carpets, PBDEs are supposed to prevent a fire from spreading. But health experts are growing concerned about a connection between PBDEs and an increase in reproductive and neurological problems, hormonal imbalance, and even cancer.

Although PBDE manufacturers insist there are no definitive health risks, government and industry leaders are beginning to take action: a first-of-its-kind bill banning the three most pervasive PBDEs is already under review by the Legislature in Washington.
