BIOSIS COPYRIGHT: BIOL ABS. The residue and release of 28 kinds of antioxidants and ultraviolet stabilizers in polyethylene products were investigated. The samples included a total of 36 kinds of kitchenware, e.g.. bags, wrapping films, sauce bottles and a chopping board, and a total of 16 food-packages, e.g., bags, cases, nets and a tube. They were analyzed using the simultaneous determination method with HPLC. Most samples contained 1 3 antioxidants, mainly Irganox 1076, Irgafos 168, BHT and Irganox 1010. The residue level was about 50 1,000 mug/g. The migration test was carried out using high-residue samples. No additives were released into water, 20% ethanol or 4% acetic acid at 60�C after 30 min, though some additives were released into n-heptane at 25�C after 60 min.
