As with selenium analysis, HGAAS also finds a place in Te determination. Basnayake et al. amended cultures of P. fluorescens K27 with 0.1 mM tellurite and, after 92-h growth, determined that approximately 34% of added Te was present as either precipitated, elemental Te in/or on centrifuged cells the balance of added Te remained in solution.190 In this same study, GC/MS was used for determination of DMTe in the same facultative anaerobe amended with tellurate.190 Earlier, GC/MS was used to analyze the headspace of a tellurium-resistant fungus amended with tellurite.215 This last is one of the few reports of the detection of dimethyl ditelluride in microbial headspace (see below).

With proof of concept established that viral vector-delivered GAA can restore biochemical and histological phenotype of affected cells and cross-correct untransduced cells, these studies were quickly followed by in vivo assessment of Ad-mediated GAA delivery in animals. Intracardiac and intramuscular delivery of Ad-human GAA (hGAA) was performed in newborn rats by Pauly et al. (1998) resulting in 10- and 6-fold normal levels of GAA...

Determination of Se by HGAAS can be interfered by As if present at a higher level than usual in biota which may result in systematic errors if no corrections are applied (errors of approx. 10% were reported in the literature [17]).

The analytical methods used to verify the between-ampoule homogeneity were ETAAS (Al, Cd, Cu, Pb and Ni) and HGAAS (As). No inhomogeneities could be detected for any of these elements in both CRMs [17]. For bromide, determinations were carried out by ion chromatography the materials were both found to be homogenous [18].
