โœฆ Synopsis

PVC was selected as the plastic to be used in these experiments. The study was performed in two different modes, representing static and dynamic conditions. The latter represented transport simulation and this was one of our major objectives: to evaluate the effects of vibrations on migration phenomena.

Our assessment of UV and GC techniques revealed that both are valuable procedures depending on the requirements of the analysis. The results obtained by the UV methodology clearly show that the change of migration per unit of time in the case of dynamic conditions is higher when compared into static conditions by a factor of 21.5. Nearly the same relationship came to light in the GC analysis of the speciยฎc migration of 2-ethylhexanoic acid into water.

## Abstract During the 1980s and 1990s, and at the EU level, the Scientific Committee for Food evaluated a number of phthalates that were being used, or were requested for use, as additives in plastics. At this time, peroxisome proliferation was considered as the pivotal effect on which toxicologic
