한국(韓國)의 영남(嶺南), 영동지역(嶺東地域) 소재(所在) 24개(個) 하천(河川)의 담수어(淡水魚) 19종(種) 76마리(길이 $5{sim}17;cm$)를 1979년 8월중 채취(採取)하여 석영관연소(石英管燃燒)-금(金) amalgam포집(捕集)-원자흡광법(原子吸光法)에 의(依)하여 총수은함량(總水鎭含量)을 측정(測定)한 결과(結果)는 다음과 같았다. 1. 채취(採取)된 담수어(淡水魚) 19종(種) 76마리의 총수은함량(總水銀含量) 평균(平均)값은 0.07ppm이었고 $0.02{sim}0.15;ppm$의 범위(範圍)를 나타내었다. 2. 평균(平均)값인 0.07ppm보다 높은 함량(含量)을 나타내는 어종(魚種)은 붕어 0.09 ppm, 버들개 0.11 ppm, 긴몰개 0.11 ppm, 기름종개 0.12 ppm, 웅어 0.10 ppm 등이었다. 3. 평균(平均)값보다 다소 높은 함량(含量)을 보이는 지역(地域)으로서 경남 김해군의 0.08 ppm, 경북 영일군의 0.09 ppm, 강원도 명주군의 0.08 ppm등이나 대부분(大部分) 비슷한 함량(含量)을 나타내었다.
The present study was carried to observe the total mercury contents in fresh-water fishes which were collected from 24 streams in the South-East area, Korea. These total mercury contents were determined by quartz tube combustion gold amalgamation method. The value of total mercury contents in collected fresh-water fishes ranged from 0.02ppm to 0.12ppm and the mean value were 0.07ppm. The total value of mercury contents differed with the fish species showing 0.09ppm in Carassius auratus, 0.10ppm in Coilia ectenes, 0.11ppm in Moroca lagowskii and Squalidus majime and 0.12ppm in Cobitis taenia which were highly more than the mean value of collected fishes. The mean value of the total mercury contents in the Yeong Il Gun (0.09PPm), Gim Hae Gun (0.08ppm) and Meong Ju Gun (0.08ppm) were highly detected than those of other surveyed areas.
