城市水生态系统中的水流通常由再生水工厂（WRP）的废水维持，这些废水含有天然和人为化学物质的混合物，并在处理过程中持续存在。在受废水影响的河流中，鱼类等水生生物在其整个生命周期中不断暴露于具有生物活性的化学品。芝加哥河（芝加哥，伊利诺伊州）的北岸河道是城市生态系统的一部分，其中>80%的年流量由北侧WRP的污水组成。在这项研究中，污水和溪流水进行了多次采样，鱼（大口黑鲈和鲤鱼）收集了两次从北岸海峡。还从密歇根湖的外芝加哥港收集了一次鱼，这是一个不受WRP排放影响的参考地点。对100多种具有不同行为和生物效应的有机化学物质进行了测定，在所有分析的水样中检测到23种化合物。最常检测到和浓度最高（>100微克/升）的化合物是乙二胺四乙酸和4-壬基酚单-四乙氧基羧酸。其他生物活性化学品，包括双酚A。在较低浓度下检测到4-壬基苯酚、4-壬基苯酚单至四乙氧基化物、4-叔辛基苯酚和4-叔辛基苯酚单至四乙氧基化物（
Stream flow in urban aquatic ecosystems often is maintained by water-reclamation plant (WRP) effluents that contain mixtures of natural and anthropogenic chemicals that persist through the treatment processes. In effluent-impacted streams, aquatic organisms such as fish are continuously exposed to biologically-active chemicals throughout their life cycles. The North Shore Channel of the Chicago River (Chicago, Illinois) is part of an urban ecosystem in which >80% of the annual flow consists of effluent from the North Side WRP. In this study, multiple samplings of the effluent and stream water were conducted and fish (largemouth bass and carp) were collected on 2 occasions from the North Shore Channel. Fish also were collected once from the Outer Chicago Harbor in Lake Michigan, a reference site not impacted by WRP discharges. Over 100 organic chemicals with differing behaviors and biological effects were measured, and 23 compounds were detected in all of the water samples analyzed. The most frequently detected and highest concentration (>100 mu g/L) compounds were ethylenediaminetetraacetic acid and 4-nonylphenolmono-to-tetraethoxycarboxylic acids. Other biologically-active chemicals including bisphenol A. 4-nonylphenol, 4-nonylphenolmono-to-tetraethoxylates, 4-tert-octylphenol, and 4-tert-octylphenolmono-to-tetraethoxylates were detected at lower concentrations (
