CHEMICAL COMPOSITION OF SURFACE WATERS AND RUNOFF OF DISSOLVED SUBSTANCES FROM THE TERRITORY OF LATVIA
The relationships between water composition, formation factors and human impact were studied. Runoff was dependent on hydrological factors, but differing levels between eastern and western Larvia. Since knowledge of the seasonal dynamics of nutrient concentrations, and of the nutrient sources and sinks are especially important, the specific loads from different parts of Larvia were evaluaied. The possible sources of the major water ingredients were identified, and their relative contrbutions to loads to waters.
