【 摘 要 】

Long-term regional emissions of air pollutants in the second half of the twentieth century led to strong changes in the quality of surface and groundwater in the Karkonosze Mts. As a result, in the most valuable natural parts of these mountains, protected in the area of the Karkonosze National Park, there was strong deforestation, which assumed the size of an ecological disaster. The various protective activities introduced at the beginning of the 1990s led to the improvement not only of the water quality, but also other ecosystems. Based on the chemical analyses of water sampled in 40 points located in the whole Park, the current state of water quality was assessed. Concentrations of some microelements were higher only in few points compared to the drinking water quality standards, which indicates a significant improvement in water quality.
