Summary/Abstract: Very few works have been devoted so far to assess the threat to brownfields by means of risk analysis. The aim of this thesis is therefore to compare selected methods of risk analysis and subsequent evaluation of their application in the assessment of security threats to brownfields as well. The assessment was performed by analyzing security threats on a selected sample of brownfields in the municipality with extended powers - Slaný, which are larger than 1 ha. There were applied four selected methods of risk analysis (DELPHI, What-If, PNH and methods of special estimates) and their comparison and evaluation of their possible application for the assessment of security threats to brownfields. Based on the performed comparative analysis, it turns out that the DELPHI and What-If methods are suitable for the analysis and could also be the primary methods for defining the relevance of threats in localities. The PNH method requires a more accurate method. Moreover, it assumes higher demands on the acquisition of input data, so its application is convenient for advanced analyses. Additionally, the method of special estimates does not seem to be very appropriate.
