Abstract

|
|
This is a study to determine the content of the mercury compound and the distribution of microorgamisms in the waste waters flowing from the chemical plants in the Ulsan area (at 4 stations). The summary of the result of this study is as follows
1. The content of the mercury compounnd has ranged from non-detection to 0.075 ppm with an average of 0. 03 ppm. The highest content has been detected from the water at station A.
2. As for the distribution of the microorganisms, one species each of bacteria, Mucor, Aspergillus, Cladosporium, and Trichothecium (T. roseum); 4 species of Penicillium; and 3 species of Sterile hyphae; a total of 12 species have been isolated
3. The following results have been found with regard to the growth of these microorganisms in terms of the content of the mercury compound. In the case of an inorganic mercury compound, most of the microbes can grow in water with a content of up to 10 ppm. Pe. sp No. 1 particularly can grow even in 50 ppm. In the case of an organic mercury compound, the growth of the microbes seems to be somewhat restrained even in 2 ppm.
