Biological Materials

Methods for the determination of boron in samples of toxicological interest have been summarized (Stokinger 1981; Van Ormer 1975). Usually total boron is determined, although in limited cases specific boron species can be determined as well. Boron is very poorly measured by atomic absorption analysis. High-temperature atomic spectrometric methods, especially inductively coupled plasma atomic emission spectrometry, including atomic emission spectrography, work well for boron. Colorimetry and prompt neutron activation analysis can also be used.

Methods for the determination of boron in biological materials are summarized in Table 6-1.

Normally, for determination in biological samples, the sample is digested or ashed, and the boron is measured by atomic spectrometric determination.
