Replacement of hexaBDE and heptaBDE


Alternatives generally exist and there is no information about any current production. However, it is reported that many articles in use still contain these chemicals.

Debromination and precursors

Polybromodiphenyl ethers can be subject to debromination, i.e. the replacement of bromine on the aromatic ring with hydrogen.

Higher bromodiphenyl ether congeners may be converted to lower, and possibly more toxic, congeners. The higher congeners might therefore be precursors to the tetraBDE, pentaBDE, hexaBDE, or heptaBDE.
