Which class of brominated compounds was widely used as flame retardants, is persistent and bioaccumulative, and is commonly detected in household dust?

Options:

Phthalates
Per- and polyfluoroalkyl substances (PFAS)
Polybrominated diphenyl ethers (PBDEs)
Organophosphate esters

Correct answer: Polybrominated diphenyl ethers (PBDEs)

Explanation: PBDEs were used extensively as flame retardants from the 1970s onward and Penta- and Octa-BDE mixtures were restricted in the EU in 2004; they are persistent, bioaccumulative, and frequent contaminants in dust and biota.
