The analysis of total nitrogen distribution in Weifang during August 2022 reveals excessive nitrogen levels during the flood season. Water quality varies across locations, primarily influenced by land-based pollution. The total nitrogen content is stable, with higher levels near the Mi River and Xiaoqing River, especially around Weifang Port, indicating significant pollution. The spatial distribution differences suggest varying pollution sources and hydrodynamic conditions. These findings emphasize the need for targeted actions, improved land-sea management, and enhanced environmental awareness to address nitrogen pollution in the region.
