SPECIATION OF LEAD IN ENVIRONMENTAL AND BIOLOGICAL SAMPLES - TECHNICAL REPORT

The speciation of lead in environmental and biological samples is revi ewed. After a brief outline of the occurrence, chemical transformation s and impact of lead species, attention is turned to the various aspec ts of the analytical chemistry of lead speciation. Sampling, storage a nd pretreatment methods for water, air, solid and biological samples a re discussed before an assessment of currently used analytical techniq ues and lead speciation schemes is made. Attempts have been directed t owards critically choosing the most significant contributions to this subject area, to aid the interested analytical chemist in the selectio n of the most suitable approaches to lead speciation and to provide a guide to the literature. Further information is readily available in s everal books [1-5] and review articles [6-17] which provide a much bro ader and more comprehensive coverage of published work.
