| Description
| - Regarding the environmental pollution, platinum group elements (PGE) are in the centre of interest of current research. 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. Comprehensive studies on PGE behaviour and effects are still lacking. Their distribution in the food chain and data on bioaccumulation has not been described so far. We focused on reproductive effects of platinum (PtCl4), 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]. Concentration range PtCl4 used in the experiment was based on preliminary tests. The concentrations of PtCl4 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 was determined after the 28-day test. The value of 28dEC50 of the boric acid test was estimated at 120 mg/kg and the measured 28dEC50 of PtCl4 was 200.4 ?M. The presented data can be considered as a step forward in the assessment of the potential risk of platinum in the terrestrial environment. However, more toxicity data for various species are needed to evaluate the environmental risk of platinum in soils.
