The presented study provides a systematic evaluation of organic and inorganic pollutants in the Bílina River from its spring to the confluence with the Labe River. Based on the analytical data polyline map diagrams are created showing the variation in the concentration of the contaminants. Changing character of the polycyclic aromatic hydrocarbons (PAHs) has been identified as a function of different dominant source of pollutants, such as petrochemicals, coals combustion products, and petroleum combustion products. The inorganic species in the Bílina river sediments show a fairly inhomogeneous regional pattern of individual elements. Abrupt increase in concentration can be spatially linked to adjacent chemical plants, brown coal open pit mines, or extraction of other mineral raw materials. Sharp decrease in the amount of some heavy metals, e.g. Co, Ni, Pb, V are observed in areas where the Bílina River is diluted by the water brought in by the Sub-Krušné hory water pipeline and by the industrial Nechranice water pipeline.
