Abstract
This is a study to determine the content of the mercury compound and the distribution of microorganisms 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 compound 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.
울산지역(蔚山地域)의 화학공장(化學工場)들의 폐수(廢水)가 흐르고 있는 곳의 4개지점(個地點)(four stations)의 수중총수은함유량(水中總水銀含有量) 및 미생물(微生物) 분포(分布)를 각각 조사하였다. 이 조사(調査)의 결과(結果)를 요약(要約)하면 다음과 같다. 1) 총수은함유량(總水銀含有量)은 불검출(不檢出)로부터 0.075ppm이고, 평균 0.03ppm인데 A지점(地點)이 가장 많았다. 2) 미생물(微生物)의 분포(分布)로는 Bacteria, Mucor, Aspergillus Cladosporium, Trichothecium(T. roseum) 각(各)1종(種), Penicillium 4종(種), Sterile hyphae 3종등(種等) 12균주(菌株)을 분리(分離)하였다. 3).이들 미생물(微生物)의 생육정도(生育程度)의 수은함유량(水銀含有量)과의 관계를 조사한 결과, 무기수은(無機水銀)에 있어서는 10ppm까지에서 대부분 생육(生育)하였으며, 그중 Pe. sp. No.1은 50ppm에서도 생육(生育)하였다. 유기수은(有機水銀)에 있어서는 2ppm에서 어느정도 생육(生育)에 저해(阻害)를 받는것 같이 보였다.
