Abstract
The residual levels and migration behavior of volatile substances were detected using HS-GC/MS for acrylonitrile-bu tadiene-styrene copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from 1,3-butadiene and sty rene found on the Japanese market. The maximum residual level of these volatile substances was 2600 μg/g of styrene in ABS toys. In particular, the levels of known carcinogens 1,3-butadiene, benzene, and acrylonitrile are 5.3, 2.5 and 55 μg/g, which are much lower than the EU limit of 0.1%. Furthermore, some volatile substances migrated from ABS toys into water in amounts of 3 - 40 ng/mL. Thermoplastic elastomer toys and rubber toys contained these volatile sub stances at significantly lower levels than ABS toys.
