The quality of the Jarosz車wka water is characterized by the lowest level of transformation of physical and chemical composition among the Bia ystok rivers. Specific pollution load, which was discharged from the catchment to the Jarosz車wka riverbed was much smaller than the load discharged to the main Bia ystok waterway (Bia a), but was similar to the load of the small urban rivers (Ba antarka and Dolist車wa). A lower degree of the Jarosz車wka spring water transformation demonstrates a significant role for pollution that flows directly to the riverbed. %K water quality %K urban river %K urban springs %K specific pollution load %U http://versita.metapress.com/content/y727t778834u3691/?p=124153b57e3d46c88cf55fc4f1210510&pi=5
