Hexabromocyclododecane (HBCDD) is a brominated flame retardant.

HBCDD's toxicity and its harm to the environment are currently discussed. In contrast to chlorinated compounds, brominated compounds have been detected in seabird eggs more recently. Measurements in seabird eggs show a significant increase in HBCDD in the period from 1983 to 2006, especially in herring gull, Atlantic puffin and kittiwake.

There is no indication of a regional difference in HCDD and insufficient data to determine differences between seabird species. Due to its persistence, toxicity, and ecotoxicity, a global ban on HBCD is currently being considered under the framework of the Stockholm Convention on Persistent Organic Pollutants.
