二噁英检测
1.人体90~95%的二恶英主要来自食物
More than 90 ~95% of the daily dioxin intake by humans result from food
2.主要来源：动物食品（如牛奶、蛋类、肉类、鱼类），植物源性产品二恶英含量较低
The main source of dioxins in food is animal food, e.g. from milk, eggs, meat, fish (food of plant origin is of lower relevance for the dioxin intake)
3.即使每日摄入极微量，也会在人体内富集
The daily consumption of low-level contaminated food leads to the accumulation of PCDD/Fs and dioxin like PCBs in human lipids
4.饲料主要污染源：环境积累
The main source for dioxin background contamination of feed is atmospheric deposition
5.TCDD人体半衰期位6-10年
The half-period for 2,3,7,8-TCDD is 6 - 10 years for human beeings
