Abstract:

In this paper a preliminary analysis is made of the number of fecal coliform bacteria in the surface layer of the nearshore waters of the south of Fildes Peninsula, using fermentation method. The results of the investigation indicate that in the surface water of the nearshore waters the highest density of the detection of fecal coliform bacteria is 40/L,generally 20/L and the lowest density less than 20/L, the latter occurring in most stations. In January, the density of the detection in the portion of the intertidal zone at the outlet of pollutant discharge is 40/L and in March 2800/L. As to the distribution of the fecal coliform bacteria, the nearer to the coast, the greater the quantity, which shows its close relation to frequent human activities. It follows that the water bodies of the near-shore waters of the south of Fildes Peninsula have been polluted by domestic sewage, the pollution being yet slight. But the trend of the pollution of the intertidal zone at the outlet of pollutant discharge should arouse our great attention.
