Analysis of phthalate migration to food simulants in plastic containers during microwave operations.

Moreira MA, André LC, Cardeal ZL - Int J Environ Res Public Health (2013)

Bottom Line: Phthalates are endocrine disruptor compounds (EDC) and are found in very low concentrations in foods, thus, highly sensitive analytical techniques are required for their quantification.BBP was not found in the samples that were analyzed.DBP was found in concentrations ranging from <LOQ to 7.5 µg/L.

ABSTRACT
Phthalates used as plasticizers in the manufacture of household containers can potentially be transferred to foods that are stored or heated in these plastic containers. Phthalates are endocrine disruptor compounds (EDC) and are found in very low concentrations in foods, thus, highly sensitive analytical techniques are required for their quantification. This study describes the application of a new method developed for analyzing the migration of dibutylphthalate (DBP) and benzylbutylphthalate (BBP) from plastic food containers into liquid food simulants. This new method employs the technique of solid phase microextraction cooled with liquid nitrogen. The analysis was conducted by gas chromatography/mass spectrometry (GC/MS) using a polyacrylate fiber. Ultrapure water was used as a simulant for liquids foods, and both new and used plastic containers were placed in a domestic microwave oven for different periods of time at different power levels. The limits of detection for DBP and BBP were 0.08 µg/L and 0.31 µg/L, respectively. BBP was not found in the samples that were analyzed. DBP was found in concentrations ranging from

Mentions: All containers were exposed to the same heating conditions; however, it is known that microwave irradiation often leads to non-homogeneous heating, which also depends on the shape and size of the containers. To evaluate the heating the simulant temperature was measured immediately after heating. A thermometer was placed into the sample, which was shaken to allow for measurement of the mean temperature. The temperatures obtained for the Group I Group II containers are presented in Figure 5 and Figure 6, respectively.
