HBCD is a brominated flame retardant found world-wide in the environment and wildlife. Human exposure is evidenced from its presence in breast milk, adipose tissue and blood. It bioaccumulates and biomagnifies in the food chain. It persists and is transported long distances in the environment, and highly toxic to aquatic organisms. It also presents potential human health concerns based on animal test results indicating potential reproductive, developmental and neurological effects. For these reasons, the Environmental Protection Agency (EPA) intends to consider initiating action under the Toxic Substances Control Act to address the manufacturing, processing, distribution in commerce, and use of HBCD.
