Abstract

A determination method was developed for 9 organotin compounds by gas chromatography/atomic emission detector (GC/AED), and their levels in kitchen utensils, food packages and toys were examined. Polyvinyl chloride (PVC) containers were found to contain a few thousand μg/g of dioctyltin compounds in all samples. They also contained monooctyltin (MOT), trioctyltin (TOT) and dibutyltin (DBT) compounds. Some also contained dimethyltin (DMT) compounds. Some PVC gloves contained DOT, MOT and TOT, and a siliconized cooking paper contained DBT, monobutyltin (MBT) and tributyltin (TBT). In the migration test, DOT and DBT in PVC containers were relatively poorly released, but DOT in PVC gloves and DBT in a cooking sheet were released readily into n-heptane, and the latter was also released into 4% acetic acid and other aqueous solvents.
