早在1885年,埃希氏从粪便中发现了大肠杆菌(Escherichia coli),尔后用它作为水、食品、土壤等被粪便污染的标志,海水中大肠菌群是水质污染的重要指标之一。假若沿海城市沿岸、海水浴场和各种养殖场等水域遭受到污水严重污染时,都可能引起某些疾病的发生和流行。因此,调查和监测沿岸水域中粪大肠菌群数,将具有重要的卫生学和流行病学意义,国外,尤其是日本对港湾、流入海域河口和太平洋沿岸水域以及某些经济性海域(如贝类养殖场)大肠菌群的分布作过大量调查研究,研究指出,盐度、pH、紫外线照射强度和海洋细菌、浮游植物所产生的有害物质是影响海水中大肠菌群存活率的重要因素,迄今为止,有关海水中粪大肠菌群的分布,我国尚未见报道。 本文对厦门港近岸水域中粪大肠菌群分布及其一些影响因素作了初步调查分析。
As early as 1885, Escherichia coli was found in the excrement of Escherichia coli, and later it was used as a marker of water, food and soil contaminated by faeces. The coliform bacteria in seawater is one of the important indicators of water pollution. If the coasts of coastal cities, beaches and various breeding farms are seriously polluted by sewage, they may cause some diseases to occur and prevail. Therefore, the investigation and monitoring of the number of fecal coliform in coastal waters will have important hygienic and epidemiological implications. Foreign countries, especially Japan, are bound by the seaports, inflows, estuaries and Pacific Rim waters, as well as certain economically exploitable seas It is pointed out that salinity, pH, ultraviolet radiation intensity and harmful substances produced by marine bacteria and phytoplankton are important factors that affect the colony viability in seawater. So far, the distribution of fecal coliform in seawater has not been reported in our country. This paper makes a preliminary investigation and analysis of the distribution of fecal coliform bacteria in coastal waters of Xiamen Harbor and some influencing factors.
