| Outline of Final Research Achievements |
The results of monitoring of water quality in the Lake Kahokugata basin showed that effluent of livestock facility and agricultural field influenced on the lake water quality. The increase in organic carbon was estimated to be caused by eutrophication in small reservoirs located in up-flow basin. Furthermore, a new wastewater treatment method was proposed. As the results of laboratory scale experiments, the method was useful for livestock wastewater treatment.
On the other hand, distribution and variation of antibiotic resistance bacteria in the basin was examined. Resistances for ST and TC were related to fecal contamination, and livestock relating facilities were one of the source of the resistance. Furthermore, it was estimated that the resistance expression was induced in the lake environment when conditions are satisfied.
