nonabromodiphenyl ether

Synonyms: "Nonabromodiphenyl ether", "Nonabromophenoxybenzene", "Nonabromodiphenyl oxide", "PBDE 206".

Source: nonabromodiphenyl ether belongs to polybrominated diphenyl ethers (PBDEs), which are a class of recalcitrant and bioaccumulative halogenated compounds that have emerged as a major environmental pollutant. PBDEs are used as a flame-retardant and are found in consumer goods such as electrical equipment, construction materials, coatings, textiles and polyurethane foam (furniture padding).
