The occurrence of triclosan (TCS) and triclocarban (TCC) in a subtropical river (Jiulong River) and its estuary was investigated for two years. TCS and TCC were ubiquitously detected in the Jiulong River and its estuary. The levels of TCS and TCC ranged from less than the method detection limit to 64 ng/L and from 0.05 to 14.1 ng/L in the river, respectively. The levels of TCS and TCC in the estuary ranged from 2.56 to 27.25 ng/L and 0.38 to 5.76 ng/L, respectively. Temporal and spatial variations of TCS and TCC in the Jiulong River and its estuary were observed during the investigation. The weather conditions did not show significant correlations with TCS and TCC, whereas several water quality parameters showed high correlations with TCS and TCC. The microcosm studies showed that both direct photolysis and biodegradation contributed to TCS removal, whereas indirect photolysis was important for TCC removal in the surface water.
在两年的时间里，对亚热带河流（九龙江）及其河口的三氯生（TCS）和三氯卡班（TCC）的发生情况进行了调查。TCS 和 TCC 在九龙江及其河口普遍存在。TCS 和 TCC 的浓度范围分别为低于方法检出限至 64ng/L 和 0.05 至 14.1ng/L。在河口，TCS 和 TCC 的浓度范围分别为 2.56 至 27.25ng/L 和 0.38 至 5.76ng/L。在调查期间，观察到九龙江及其河口 TCS 和 TCC 的时空变化。天气条件与 TCS 和 TCC 没有明显的相关性，而一些水质参数与 TCS 和 TCC 呈高度相关性。微宇宙研究表明，直接光解和生物降解都有助于 TCS 的去除，而间接光解对地表水 TCC 的去除很重要。
