Description
  • Trace concentrations of the platinum group elements (PGE; Pt, Pd and Rh) are nowadays an irreplaceable part of the environmental analysis and assessment. These rare elements are used as effective substances in automotive catalysts to reduce pollution by emissions originating from fuel combustion. Due to their harmful potential, it is necessary to monitor their content and behaviour in different samples. From the assessing of the effects of chemical substances, using ecotoxicological bioassays with different trophic levels can be obtained very valuable information of bioavailability in the ecosystems. We focused on reproductive effects of platinum (PtCl4), palladium (PdCl2) and rhodium (RhCl3), in particular. Our study is based on a collembolan laboratory breed, test optimalization and validation according to the OECD 232 standards [CSN ISO 11267 - Soil quality - Inhibition of reproduction of Collembola (Folsomia candida) by soil pollutants]. The concentrations of PGE tested were as follows: 5, 10, 25, 50 and 100 ?M. The results were evaluated using the inhibition of reproduction compared with controls. The EC50 (effective concentration) was determined after the 28-day test.
