Ecotoxicological study on human exposure to trace elements in northeast Asia

采用食物重复法对中国和韩国的3对双生子进行了膳食微量元素的调查，特别是铅和镉的摄入量，一个省会城市的妇女和首都附近一个农村的妇女之间的关系。24- 1999年在吉林省和2000年在阜南省对50名不吸烟妇女进行双生子调查，2000年1月在韩国济州道进行的双胞胎调查中，对33名和34名不吸烟妇女进行了包括血液学和血清生化检查在内的268名受试者进行了体格检查，并对两份样本进行了营养成分分析。吉林省、福建省和济州省城市妇女膳食铅摄入量的几何平均值分别为13.2 μ g/d、33.0 μ g/d和13.0 μ g/d， ...更多信息 而农村妇女的这一比例分别低于14.5微克/天、49.8微克/天和17.9微克/天。以吉林省、福建省和济州省为代表的城市妇女血铅值分别为75.2ng/ml、70.0ng/ml和23.8ng/ml，农村妇女血铅值分别为74.1ng/ml、91.4ng/ml和24.7ng/ml。吉林省、阜南省和济州省城市妇女膳食镉摄入量分别为8.9 μ g/d、30.2 μ g/d和16.0 μ g/d，农村妇女膳食镉摄入量分别为5.3 μ g/d、66.3 μ g/d和18.7 μ g/d。以吉林省、府南省和济州省为代表的城市妇女血镉值分别为0.73、1.75和1.26 ng/ml，分别为1.05 ng/ml，2.62 ng/ml和1.42 ng/ml引起阜南农村妇女血镉水平和膳食镉摄入量的原因值得注意和研究是如此之高。少

Three twin surveys in China and Korea were done by the food duplicate method to study on the dietary intake of trace elements, specially with reference to lead and cadmium, between women in a provincial captial and women in a farming village in the vicinity of the capital.The 24-hr food duplicate samples were collected from 50 nonsmoking women at each other in the twin survey in Jinlin province in 1999 and in Funan province in 2000 in China, and from 33 and 34 nonsmoking women at each other in the twin survy in Jeju province of Korea 1n 2000.The physical examinations including hematology and serum biochemistory tests were worked for the subjects of 268 in total.Nutritional analysis of the duplicate samples were conducted utilizing the national standard food conpo-sition tables for each other.The main results were shown as follow. The dietary lead intakes of 13.2ug/day, 33.0 ug/day and 13.0ug/day for each other of urban women in Jinlin, Funan and Jeju province as geometric mean(GM)were … More lower than 14.5ug/day, 49.8 ug/day and 17.9ug/day for the counterparts of rural women. The blood lead values(GM)were 75.2 ng/ml, 70.0 ng/ml and 23.8 ng/ml for the urban wonen in Jinlin, Funan and Jeju province representatively and were 74.1 ng/nl, 91.4 ng/ml and 24.7ng/ml for the rural women at each other. There was no difference of the blood lead level between urban and rural women except Funan province.The dietary cadmium intakes were 8.9ug/day, 30.2 ug/day and 16.0ug/day for each other of urban women in Jinlin, Funan and Jeju province as GM and were 5.3ug/day, 66.3 ug/day and 18.7 ug/day for the counterparts of rural women. The blood cadmium values(GM)were 0.73 ng/ml, 1.75 ng/ml and 1.26 ng/ml for the urban women in Jinlin, Funan and Jeju province representatively and were 1.05 ng/ml, 2.62 ng/ml and 1.42 ng/ml for the rural women at each other.It is noticed and must be studied what it causes the blood cadmiun levels and the dietary cadmium intakes of rural women in Funan province are so high.
