The DNA barcoding project provides a very quick and easy way to identify different types of organisms based on their DNA. The main objective of this study is to obtain the sequences of different species of fungi, plants and animals to map the biodiversity of Slovakia. This project also represents a new use for collections stored in natural history museums around the world. This paper shows in particular a laboratory view of the DNA barcoding project, such as the practical application of the methodology for differe...

Species of macrofungi were collected from extremely polluted sampling spots in the vicinity of abandoned antimony mines in Slovakia. Concentrations of potentially toxic elements in plants and fungi were determined by ICP-MS and in soils and sediments by both ICP-MS and ICP-ES. Of the edible species the highest values of arsenic and cadmium were recorded in Agaricus arvensis, lead in Imleria badia and representatives of the genera Boletus, Leccinum and Suillus accumulated high levels of mercury. Suillus species als...
