Butylated hydroxytoluene (BHT) is an antioxidant utilized as additive in foods
and packaging plastic. Its presence in drinking water is possible if it is used
as an antioxidant in the packaging plastic because it may migrate into the
package's contents. A method for the determination of BHT in water by means of
solid-phase microextraction and gas chromatography-mass spectrometry has been
developed and evaluated with respect to the time of fiber exposure, limits of
detection and quantitation, linearity and precision. Finally, the method was
applied to evaluate the presence of this substance in samples of mineral and
mineralized bottled drinking water, and it appeared to be present in seven out
of a total of fifteen commercial brands.
