Total Mercury Content of Restaurant Meals in Seoul Area
대중음식중의 총 수은 함량 측정
Abstract
This study was performed to investigate the mercury concentration of restaurant meals and to estimate the total dietary intake of mercury. Experimental subjects were 66 cases in 11 kinds of common restaurant meals collected from the Seoul area. Total mercury was determined by Hg-analyzer and two kinds of atomic absorption spectrophotometer (AAS). The results were as follows: 1. Mean value of mercury contents in fluid of meals was about 0.002 ppm and there was no significant difference between the two methods. 2. Mercury concentration of residue by AAS was significantly higher than that by Hg-analyzer. The mean values of mercury concentration were 2.423 ppm, 10.229 ppm and 11.655 ppm by Hg-analyzer, AAS-PE and AAS-Hi, respectively. 3. Dietary intake of mercury from the meals was estimated
1988년 11월~12월 사이에 서울시내 각 식당에서 구득한 설렁탕외 10종의 대중식사 66건에 대한 수은함량을 수은분석기와 원자흡광광도계에 의하여 분석한 결과 다음과 같은 결과를 얻었다. 1. 국물의 평균 수은 농도는 측정방법이나 기기의 종류에 따른 차를 인정할수 없었으며 그 농도는 0.002ppm 정도였다. 2. 고형물의 경우 평균 수은농도는 수은분석기의 분석치에 의하면 0.007ppm, 그리고 AAS 에 의한 분석결과는 0.027ppm~0.030ppm으로 나타났으며 분석방법에 따른 차이는 유의성이 인정되었다. (p<0.01). 3. 대중식사 3그릇으로부터 측정한 1일 평균 수은섭취율은 수은분석기에 의하면
