【 摘 要 】

This study focuses on some sulfa-drugs that have been heavily used in livestock husbandry and emitted into the Lake Biwa and Yodo River Basin. Emissions of sulfa-drugs were estimated using the national statistical data on veterinary drug usage and livestock excrement in Japan. One-box and distributional type multimedia fate models were utilized with the estimated emissions in order to simulate the behaviour of sulfa-drugs in four environmental media (atmosphere, soil, water and sediment) in the study period from 2005 to 2015 in the basin. Based on the calculated results, sulfa-drugs emitted to the soil media were efficiently transported to water, which resulted in the largest amount in water among the environmental media and high concentrations in and around areas with large farmland proportion.
