Fifteen polybrominated diphenyl ethers, tetra- thru deca-isomers, were reported to absorb at wavelengths >290 nm and therefore are expected to be susceptible to direct photolysis by sunlight. PBDEs are a class of substances that contain the same base structure but differ in the number of attached bromine atoms. PBDEs do not occur naturally, but are man-made. They are generally produced as commercial mixtures which may contain varying combinations of PBDEs.

Polybrominated diphenyl ethers (PBDEs) are a group of congeners, mainly used as flame retardants in a variety of materials including plastics, textiles, electronic products, building materials, furnishings and vehicles (Figure 1). The chemicals -- called polybrominated diphenyl ethers (PBDEs) -- are used as flame retardants in items like furniture and carpets. For the study, researchers analyzed blood samples from over 3,500 pregnant women, including 184 whose babies were born early, for blood levels of PBDEs. Nearly all had detectable levels of PBDEs in their blood.

These chemicals are intended to slow the rate of ignition and fire growth, allowing people more time to escape from a fire or extinguish it. In recent years, PBDEs have generated international concern over their widespread distribution in the environment, their potential to bioaccumulate in humans and wildlife, and their suspected adverse human health effects.
