Sažetak
Polycyclic aromatic hydrocarbons (PAUs) are organic compounds that are retained in the environment due to their inertness and chemical stability. They consist of two or more condensed aromatic rings and are formed by the incomplete combustion or pyrolysis of organic matter, naturally or during industrial processes and other human activities. They are sensitive to light, resistant to heat and corrosion, and have different toxic effects like genotoxic, carcinogenic, teratogenic and phototoxic among others. Polycyclic aromatic hydrocarbons reach surface waters via precipitation or by direct oil spillage, the discharge of untreated wastewater and the disposal of waste containing PAHs. In humans and animals, they can cause lung, stomach, colon, esophageal, prostate, and bladder cancers. Varaždin County is a significant hydrographic junction in Croatia and is well known for its agricultural production and developed industry. The rapid development of industry and the overuse of fertilizers in agriculture contributes greatly to surface water pollution. Currently, more than 100 PAHs have been recognized in nature by the US Environmental Protection Agency and the World Health Organization, 16 of which are classified as primary, most dangerous and can cause pollution of surface waters. The determination of the PAH concentration is carried out by gas chromatography mass spectrometry. A major advantage of this method is the detection of very low concentrations of PAH that are common in the Varaždin County area, which means that surface water quality is satisfactory given the concentrations of PAH do not exceed the maximum permissible values.
