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

人类活动对南极生态系统的影响是 在这个原始和脆弱的环境中的重要问题。 在 特别是从麦默多站排放未经处理的污水 已经引起了环境组织的极大关注。 在 与此同时，很少有人知道肠道的持久性， 南极海洋指示菌和病原菌 环境 McFeters提出解决关键问题， 涉及潜在的公共卫生和环境影响， 将未经处理的污水排入南极海水。 而且 假设污水羽流不会延伸到该地区 麦默多站的饮用水取水口 这一假设 鉴于肠内毒素的持久性， 麦克默多湾的细菌和水流 麦克费特斯将描述 在最高占用率情况下污水羽流的范围 在麦默多站和潜在的健康以及 目前污水处理对环境的影响 实践 这些信息将适用于其他极地 人类活动的增加对当地构成威胁的地区 生态系统

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.
