ABSTRACT: The residual levels and migration behavior of volatile
substances were detected using HS-GC/MS for acrylonitrile-butadiene-styrene
copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from
1,3-butadiene and styrene 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 substances at significantly lower levels than ABS
toys.
