Migration levels of PVC plasticisers: Effect of ionising radiation treatment

► CPE is effective for plasticiser extraction at ppb levels from aqueous solutions. ► DEHA-ATBC migration in aqueous simulants is 10-100 and 171-422 ppb, respectively. ► 10% v/v ethanol > 3% w/v acetic acid > distilled water for ATBC migration. ► Aqueous acetic acid (3%) is the most aggressive simulant for DEHA plasticiser. ► Gamma radiation (15-25 kGy) induces a significant increase in DEHA-ATBC migration.
