EPA Action Plan for Hexabromocyclododecane

Thursday, October 14th, 2010


HexabromocyclododecaneThe EPA is considering hexabromocyclododecane, a brominated flame retardant made up of various mixtures of its 16 isomers (herein: HBCD), for action under the Toxic Substance Control Act (TSCA). This is in addition to two other groups of compounds already discussed in previous Lab Science News articles.

HBCD is ubiquitous in the environment throughout the world and is also found in human tissues, including blood, adipose, and breast milk. When released into the environment, it can travel great distances, bioaccumulating and biomagnifing in the food chain. In addition to its high toxicity to aquatic organisms, studies have also linked HBCD to reproductive, developmental, and neurological effects in humans, with a potentially higher impact on children because of their smaller size.

Stormwater GuidelinesEPA has finalized national effluent limitations guidelines (ELG) and new source performance standards (NSPS) for construction and development sites to help address improvement of water quality throughout the nation. While the standards focus on discharges occurring during stormwater events, these new guidelines affect all discharges of pollutants from construction activities into waterways, including dewatering and concrete washout.
