Soil contamination by polycyclic aromatic hydrocarbons from local heating

Polyaromatic hydrocarbons (PAHs) are the pollutants of the environment. These dangerous chemical compounds are produced by man and its activities. The source of these pollutants are mainly burning of fossil fuels and biomass, as well as transportation and industrial production. From the literature they were obtained evidence regarding PAHs, their properties and group trends. For the main PAHs was found their relative genetic toxicity and was described mechanism of their effect on DNA. Based on the literature was compiled ranking of fuels with respect to the production of PAHs. The monitoring of untouched area by industry and transportation. The sampling was done in the surroundings Bušanovice village located in Prachatice district. The samples were taken from surface soil horizon. Samples were taken in 2015 to various remote locations from the center of the village. These samples were analyzed by HPLC technique. It was found that the largest source of contamination are local furnaces burning solid fuels such as wood and coal. The concentrations of PAHs in the samples was in the range of 0.24 to 19.21 mg / kg dm. These values are considerably higher than was expected and in the European scale concentrations correspond to large cities with heavy traffic or industrial areas
