  1. Transport and dilution of fluvial antibiotic in the Upper Gulf of Thailand.2021/11/01Wang Aobo,Guo Xinyu,Morimoto Akihiko,Maetani Kana,Tanoue Rumi,Tong-U-Dom Siraporn,Buranapratheprat AnukulEnvironmental pollution (Barking, Essex : 1987)288, 11777910.1016/j.envpol.2021.117779A three-dimensional hydrodynamic-antibiotic model is developed to investigate the transport and dilution of sulfamethoxazole (SMX) in the Upper Gulf of Thailand (UGoT). The simulation produced a spatially averaged annual mean SMX concentration of 0.58 μgm, which varied slightly between seasons assuming a temporally constant river SMX loading observed in August. In contrast, the horizontal distribution of SMX concentrations strongly varied with season because of the changing residual currents. In addition, SMX is diluted to concentrations lower than 10% of those in river waters a short distance offshore of the estuaries. To better understand this behavior, we examined the relationship between salinity and SMX concentrations in the UGoT. The annual budget demonstrates that 98% of SMX in the UGoT is removed by natural decomposition. As the concentrations of fluvial pollutants in the UGoT depend on their river loading and decomposition rates, functions were derived to predict pollutant concentrations and flushing times based on the river input flux and half-life.
