简介
We collaborated with 26 groups from universities across the United States to sample 42 sites for 33 trace organic compounds (TOCs) in water and sediments of lotic ecosystems. Our goals were 1) to further develop a national database of TOC abundance in United States lotic ecosystems that can be a foundation for future research and management, and 2) to identify factors related to compound abundance. Trace organic compounds were found in 93% of water samples and 56% of sediment samples. Dissolved concentrations were 10–1000 × higher relative to sediment concentrations. The ten most common compounds in water samples with detection frequency and maximum concentration were sucralose (87.5%, 12,000 ng/L), caffeine (77.5%, 420 ng/L), sulfamethoxazole (70%, 340 ng/L), cotinine (65%, 130 ng/L), venlafaxine (65%, 1800 ng/L), carbamazepine (62.5%, 320 ng/L), triclosan (55%, 6800 ng/L …
