Przeprowadzono badania fizyczne i chemiczne wody rzeki Bystrzycy Dusznickiej i jej dopływów na terenie miasta Polanica Zdrój. Badane wody okazały się czyste, posiadały niską zawartość metali ciężkich z wyjątkiem rtęci i ołowiu. Podwyższone stężenia tych dwóch pierwiastków wynikały zapewne z emisji bliskiego oraz dalekiego zasięgu.

The investigations were carried out in area of the town Polanica Zdrój from March 2000 to September 2000. The aim of this work was to examine quality of waters from Bystrzyca Dusznicka river and its three tributaries. These analyses include some parameters of rivers' water with heavy metals. The research waters had a low conductivity, so this water was clean. Furthermore there were not much chloride, sulphate, sodium and potasium. These waters could be describe like soft waters because there were a low total hardness, calcium and magnesium. Concentration of heavy metals was rather low. Only level of the lead and the mercury was higher. These indicate that pollution come from far and close athmospheric sources.
