Persistence and Environmental Impact of Enteric Bacteria in an Antarctic Marine Environment

在这个原始而脆弱的环境中，人类活动对南极生态系统的影响是一个重要问题。特别是麦克默多站排放未经处理的污水，引起了环境团体的高度关注。同时，对南极海洋环境中肠道指示菌和致病菌的持久性了解甚少。McFeters提议解决与向南极海水排放未经处理的污水可能造成的公共健康和环境影响有关的关键问题。此外，假设污水羽流不会延伸到麦克默多站的饮用水取水口区域。鉴于麦克默多湾肠道细菌和洋流的持续存在，这一假设尚未得到验证。McFeters将描述麦克默多站在最大占用情况下的污水羽流范围，以及目前污水处理做法对健康和环境的潜在后果。这些资料将适用于人类活动日益增加对当地生态系统构成威胁的其他极地地区。

The influence of human activities on Antarctic ecosystems is an important issue in this pristine and fragile environment. In particular, the release of untreated sewage from McMurdo Station has drawn considerable attention from envirnomental groups. At the same time, very little is known about the persistence of enteric indicator and pathogenic bacteria in the Antarctic marine environment. McFeters proposes to address key questions that relate to the potential public health and environmental impact of releasing untreated sewage into Antarctic sea water. Moreover, it is hypothesized that the sewage plume does not extend to the area of the potable water intake for McMurdo Station. This hypothesis remains untested in view of the extended persistence of enteric bacteria and currents in McMurdo Sound. McFeters will describe the extent of the sewage plume under maximal occupancy circumstances at McMurdo Station and the potential health as well as environmental consequences of the present sewage disposal practices. Such information will be applicable to other polar regions where increasing human activity poses a threat to the local ecosystem.
