| Abstract: | The loss of lead in various kinds of biological materials after drying and ashing was investigated using 203PbCl2 incorporated into the materials concerned through incubation with intraveneous injection of the tracer.Experimental results show that although oven ashing could be used for analysing the lead in lung,kidney and liver etc., oxygen plasma ashing and high pressure digestion are the most suitable methods for the determination of Pb in biological materials. |
