title: [Analysis of the effects of physico-chemical factors on the stability of lead and mercury levels in biological specimens. I. Biological specimens with the addition of Pb and Hg standards].
abstract: For the analysis of the process of precipitation and adsorption in the walls of polyethylene and glass vessels in which biological specimens containing mercury and lead were stored, the techniques of scanning electrone microscopy and X-ray microanalysis were applied. It was observed that the losses of: --lead in stored urine specimens were mainly due to precipitation, --mercury in stored urine specimens occur, among others, through adsorption on vessels' walls. X-ray microanalysis may also facilitate determination of the chemical composition of micro-structural fragments deposited on the surface of vessels.
