Effect of Agriculture Nitrogen on Water Quality in Lithuanian Rivers, The
分析立陶宛河流的氮浓度时间趋势，研究大规模农业生产对硝酸盐径流的影响，利用国家监测数据评估长期水质变化，为波罗的海污染治理提供参考。
Nitrogen concentration time trends from Lithuanian rivers were analyzed to provide information on the amount, sources, and causes of nitrate runoff to the Baltic Sea from Lithuania. This investigation focused on the impact of large-scale agricultural production on nitrate concentration in the rivers. Long-term water quality changes were determined using the national monitoring data from the Lithuanian Ministry of Environmental Protection.
