Chromatografické analýzy těkavých organických látek v životním prostředí

Abstract

Volatile organic compounds (VOCs) include a large and diverse group of carbonaceous matters with low molecular weight and high votality. These subtances are ever-present in the environment, and it´s chemical charakter is very various. Main negative effects are formation of tropospheric ozone, toxicity, carcinogenic effects and destruction of the ozone layer.

Concentration of volatile organic compouds in air has declined more than half, in compare with last decade. Demonstreble negative impact of these substance on air quality and environment with implications for human health and the biosphere include these substance between more regulate and restriction pollutants. Therfore, it is curently an increased focus on methods of measuring and determination.
