ABSTRACT
An increased worldwide usage of platinum group elements (PGE) has been observed during recent
decades. High amounts of PGE are applied in such areas as chemical industry and jewellery production,
but the increased demand for these metals primarily depends on the introduction of automobile catalytic
converter systems. Catalytic converters have also been considered to be a major source of PGE pollution.
The similar Pt:Rh ratio, which is used in these autocatalysts, was found in various environmental samples
as well. The present literature review indicates that the concentration of these metals has increased considerably
in the last twenty years in different environmental matrices, resulting in ecological and human health
risks. Because of the importance of PGE and their trace levels in environmental and biological matrices,
sensitive methods are required for reliable determination. Details of the particular steps of analytical procedures
for PGE quantification in environmental samples such as road dust, airborne particulate matter, soil,
benthic sediments, water, wastewater and biological samples are discussed. Sampling and sample storage
and preservation techniques are presented. Moreover, the most frequently used extraction, enrichment,
detection and determination procedures for PGE are described.
