In inner coastal waters such as lagoons, which are very turbid and rich in suspended particles, the survival of fecal pollution microorganisms may find favorable environments. In order to better characterize the sources and dynamics of fecal pollution in a strongly turbid environment, in situ observations were made in the Curonian Lagoon. A combination of traditional monitoring and molecular methods were used. To monitor the water quality, the indicator Escherichia coli (EC) was selected as a proxy for fecal contamination. E. coli concentration correlated with environmental parameters as pH, oxygen and turbidity. The main pollution sources are the sewage outlets in the lagoon area, while the pollution coming via rivers did not play a significant role. Still the human associated E. coli consisted only of 0 up to 20% of analyzed isolates, and did not correlate with the E. coli concentrations in the study sites. The role of birds, especially for potentially virulent E. coli may be underestimated in the lagoon.
在内陆沿海水域，如泻湖，那里非常浑浊，富含悬浮颗粒，粪便污染微生物的生存可能会找到有利的环境。为了更好地描述强浑浊环境中粪便污染的来源和动态，在库尔斯沙嘴泻湖进行了现场观测。采用了传统监测和分子方法相结合的方法。为了监测水质，选择大肠杆菌 (EC) 作为粪便污染的指示剂。大肠杆菌浓度与环境参数（如 pH 值、氧气和浊度）相关。主要污染源是泻湖地区的污水出口，而河流带来的污染没有起到重要作用。尽管如此，与分析的分离株相比，与人类相关的大肠杆菌仅占 0 到 20%，并且与研究地点的大肠杆菌浓度无关。鸟类的作用，特别是对潜在有致病性的大肠杆菌的作用，在泻湖中可能被低估了。
