Formation of PBDD/F from PBDE in electronic waste in recycling processes and under simulated extruding conditions

The total content of ∑PBDFs was around 1 × 103 μg kg−1. Such contents in materials do not pose a risk for consumer under normal conditions. Workers at recycling plants might be at risk. The measured formation rates of PBDFs were between 2 × 10−5 and 2 × 10−4 ∑PBDE−1 min−1.
