Lichen, or lichenized fungi, is one of the most efficient on air pollution biomonitoring among the biomonitors. Biomonitoring has been used as an alternative method to study the air pollution in several countries, however, in Brazil, systematic use of lichens as biomonitors of environmental pollution is quite rare. In order to make an assessment of the air quality of the Mangabeiras’ Park,...

The Portuguese settlers arrived in the coast of the Brazilian State of Espírito Santo in sixteenth century and built several “Missões Jesuíticas” (Jesuitical Missions). In spite of living within the Mission and been catechized, the Indians, Tupiguarani Tradition, kept on producing traditional handcraft, as the decorated ceramic, however, they introduced European elements during the production...

Poster

Minor and trace elements composition of bottom sediments from water bodies in Western Paraguay have been investigated by XRF techniques to determine their correlation as well as provenance. The analysis of complex spectra was performed by the AXIL software and the quantitative analysis by the QAES software. Analysed trace elements were refractories Rb, Ba, Nb, La, Ce, Sr, Nd, Zr, Y and other...

The concentrations of some trace and essential element constituents in nine medicinal plants surveyed in Bucegi Mountains in Romania, namely Achillea millefolium, Chelidonium majus, Cynara scolymus, Hypericum perforatum, Tilia cordata, Matricaria recutita, Mentha, Rosa canina and Urtica, were determined. The above medicinal plant species were used for the experiments as they are an important...

Poster

The impacts of the trace heavy metals released by different industries on croplands were monitored by different environmental media. All the sampling locations based on a regular monitoring grid network were selected. To all samples collected in area of the smelter complex (20 x 20 km²), one to three locations has to be contributing to each sampling location. The spots were further...

352. Trace element distribution in human teeth by X-ray fluorescence and multivariate analysis

Nuclear Analytical Methods

Poster

X-ray fluorescence spectrometry (XRFS) was used as a multielement method of evaluation of individual whole human tooth or tooth tissues for their amounts of trace elements. Measurements were carried out on human enamel, dentine, and dental cementum, and significant differences in tooth matrix composition were noted. In addition, the elemental concentrations determined in teeth from subjects of...
