了解人类诺如病毒（NoV）在海洋环境中的命运是更好地控制贝类相关NoV胃肠炎的关键。我们量化的NOV和大肠杆菌在污水中的雨水池排放和处理后的污水处理后的UV消毒厂活性污泥处理，并研究了这些微生物的命运在牡蛎收获区频繁的雨水排放和不频繁的淡水排放的影响。牡蛎监测点位于影响捕捞区的废水处理厂（WwTW）排污口下游。牡蛎体内NoV的衰减速率随离排污口距离的变化比E.大肠杆菌的浓度为同一数量级，距离排污口超过7公里。水平E。大肠杆菌在牡蛎从更多的潮汐影响地区的河口高水周围比周围低水，而潮汐流量没有影响的诺氏病毒污染的牡蛎。该研究提供了关于NoV和E的污染概况和负荷的比较数据。大肠杆菌在商业牡蛎渔业受WwTW的影响。
Knowledge of the fate of human noroviruses (NoV) in the marine environment is key to better controlling shellfish-related NoV gastroenteritis. We quantified NoV and Escherichia coli in sewage from storm tank discharges and treated effluent processed by a UV-disinfection plant following activated sludge treatment and studied the fate of these microorganisms in an oyster harvesting area impacted by frequent stormwater discharges and infrequent freshwater discharges. Oyster monitoring sites were positioned at intervals downstream from the wastewater treatment works (WwTW) outfall impacting the harvesting area. The decay rates of NoV in oysters as a function of the distance from the outfall were less rapid than those for E. coli that had concentrations of NoV of the same order of magnitude and were over 7 km away from the outfall. Levels of E. coli in oysters from more tidally influenced areas of the estuary were higher around high water than around low water, whereas tidal flows had no influence on NoV contamination in the oysters. The study provides comparative data on the contamination profiles and loadings of NoV and E. coli in a commercial oyster fishery impacted by a WwTW.
