ChemSec’s SIN List, a database of chemicals likely to be banned or restricted in a near future, writes that decabromodiphenyl ether / decaBDE is “reported to have developmentally toxic and endocrine disruptive effects. It is persistent but has been shown to have the potential to degrade to compounds with PBT/vPvB properties*. Deca BDE is commonly found in humans and the environment”.
The substance is on The European Chemicals Agency (ECHA) Candidate List of “Substances of very High Concern.”
*PBT and vPvB substances stands for Persistent (chemicals that does not break down in environment, Bioaccumulation (substances that build up in organisms), and Toxicity (harming the entire food chain, animals and humans, with effects like cancer, endocrine disruption and reproductive problems)
