Abstract  

Trace elements present in the leaves of “Populus” grown in the city of Athens are determined by XRF, and compared with leaves of trees grown far from the city. The results of this work show a manyfold increase in the bromine content of the leaves in trees grown in the city. The increased presence of this element is attributed entirely to the increase of the bromine content in the air of the city, due to car exhaust, from which the leaves uptake this element. The implication to public health of this finding is discussed.

Abstract  

Skin tissue samples from 41 patients suffering from skin epitheliomas were analyzed by the PIXE method. Skin samples from the non-affected areas and blood serum were also analyzed for the same patients. The elements determined were K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, and Pb. Their concentrations in the healthy skin and the serum were normal. The concentrations in the lesions were nearly the same for both basal cell and squamus cell epitheliomas (BCE and SCC) except for higher zinc and lower bromine values in the BCE samples. However, substantial differences were observed between the affected and non-affected skin.
