The thesis discusses the possibilities of determination of chlorophenols in beer. A review of literature describes the complex properties of chlorinated phenols. Summarizes their physical, chemical and toxicological properties and characterizes their possible inputs into the environment. In the experimental part is the main theme of the determination of chlorophenols in samples of small breweries and beers called as home brew. These are various types of beer, in which the amount of chlorophenols determined using solid phase extraction (SPE) using gas chromatography with flame ionisation detector (FID). Another part of the experiment is aimed at demonstrating the formation of chlorophenols in beer by simulating conditions in the production of beer in the pilot plant. Chlorphenols amount of boiled beer is again determined by gas chromatography. Samples of beers are compared with each other in the content of chlorophenols. It is evaluated sectional representation monitored chlorophenols and their quantity in the analyzed samples of beer.
