项目摘要

At present, little is known about the occurrence of polybrominated diphenyl ethers (PBDEs) in fish and food products sold in Japan. To investigate whether human exposure to PBDEs through the diet is significant, the concentrations of PBDEs were determined in fish and in meat and vegetables sold in two food markets in the city of Hirakita, Osaka prefecture. The concentrations of PBDEs in the breast milk of 12 primiparae nursing women at one month after delivery also were determined to ascertain the relationship between the levels found in the diet and levels in humans. E PBDEs concentrations ranged between 21 and 1,650 pg/g fresh weight in the edible tissues of five species of fish and one shellfish species. The highest concentrations were measured in yellow-fin tuna, followed by short-necked clam, salmon, yellowtail, mackerel and young yellowtail. Interestingly, 」 PBDE concentrations were not statistically significantly different in two cultured mackerel samples from Japan and mackerel collected from northern European waters. E PBDE concentrations in beef, pork and chicken meat (ranging between 6.25 and 63.6 pg/g fresh weight) and hi three different vegetables (ranging between 38.4 and 134 pg/g fresh weight) were significantly lower than the concentrations in fish/ In human milk, 2 PBDE concentrations ranged between 668 and 2,840 pg/g lipid basis, which is comparable to the levels in populations of nursing women reported hi Sweden and elsewhere. There was a strong positive relationship between PBDE concentrations in human milk and dietary intake of fish and shellfish, which was established in the women from responses to a questionaire on food consumption habits. The results of this study of food products commonly consumed in Japan and the levels found in nursing women raises a concern about low level PBDE contamination of fish and other foods intended for human consumption.

目前，关于日本出售的鱼类和食品中多溴二苯基醚（PBDES）的发生知之甚少。为了调查人类通过饮食暴露于PBDES是否很大，PBDE的浓度是在鱼类和大阪居住地的两个食品市场中出售的肉类和蔬菜中确定的。分娩后一个月的12名Primiparae护士妇女的母乳中PBDE的浓度也确定确定饮食中发现的水平与人类水平之间的关系。在五种鱼类和一种贝类物种的可食时，E PBDE浓度在21至1,650 pg/g之间。最高的浓度是在黄鳍金枪鱼中测量的，然后是短颈蛤，鲑鱼，黄尾，鲭鱼和年轻的Yellowtail。有趣的是，在日本的两个培养的鲭鱼样品和从北欧水域收集的鲭鱼中，PBDE浓度在统计学上没有显着差异。牛肉，猪肉和鸡肉的E PBDE浓度（范围为6.25至63.6 pg/g新鲜重量）和三种不同的蔬菜（38.4和134 pg/g新鲜重量介于38.4和134 pg/g新鲜重量之间）的浓度明显低于人类牛奶的浓度，2 pbde的浓度为668和2 pbd，范围为668和2,840 pg/g lipid，占相当的水平，这是相当的，这是相当的，这是相当的，这是相同的，这是相当的，这是相同的，这是有效的，这是有效的，这是有效的，这是有效的，这是相当的含量。瑞典和其他地方。人力牛奶中的PBDE浓度与鱼类和贝类的饮食摄入量之间存在很强的正相关关系，这是从对食物消费习惯的问题的回答中建立的。这项对日本通常食用的食品的研究结果以及护士妇女中发现的水平引起了人们对鱼类和其他供人类消费的食物的低水平污染和其他食品的关注。
