在冬季和春季期间，对地中海一条小河（法国南部的阿尔克河）中9种选定抗生素的出现和分布情况进行了调查。卡马西平和克拉霉素是水中最常检测到的化合物。由于冬季没有背景水的稀释作用，在河水中检测到克拉霉素的浓度达到较高的微克/升水平，而克拉霉素和阿奇霉素在沉积物中普遍存在。这些污染水平比欧洲大型河流所报道的污染水平高出一个数量级。可以表明，克拉霉素可被视为河流水体中需重点监测的抗生素，主要是因为这种化学物质在水中具有高持久性，并且在沉积物中的消散过程缓慢。（C）2008爱思唯尔有限公司。保留所有权利。
The occurrence and distribution of nine selected antibiotics were investigated in a small Mediterranean stream (Arc River, Southern France) during the winter and the spring season. Carbamazepine and clarithromycin were the most frequently detected compounds in water. Ctarithromycin was determined at high mu g/L Levels in river water during the winter season due to the lack of dilution by background water while clarithromycin and azithromycin were ubiquitous in sediment. These contamination levels were at one order of magnitude higher than those reported in large European rivers. It could be shown that clarithromycin can be regarded as a priority antibiotic to be monitored in river waters mainly because this chemical showed high persistence in water and underwent stow dissipation processes in sediment.
