Leaching of FRs from recycled ABS plastic in birds’ digestive fluids

Recycled ABS was obtained from a plastic producer in China. Levels of individual FRs analysed in the ABS were highest for BTBPE at 1.8 mg/kg, with DecaBDE (BDE 209), several other brominated FRs and TPHP and EHDPP also around 1 mg/kg. Results showed that lipophilic FRs had a higher tendency to migrate out of the plastic, in particular BDEs, BTBPE and DBDPE. This could be related to affinity to bile salts and enzymes in birds’ digestive fluids.
