A study of the dietary intake of dioxins, consisting of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and coplanar polychlorinated biphenyls (Co-PCBs) through baby foods in the metropolitan Tokyo area was carried out. The samples were homemade baby foods prepared by the total diet-market basket method and baby foods (mainly commercial items) prepared by the duplicate portion method. The daily intake of dioxins per kg of body weight from baby foods in each weaning stage for the case of half intake of homemade baby foods and the other half of mainly commercial items was 0.32 pg TEQ/kg/day in the early stage, 0.45 pg TEQ/kg/day in the intermediate stage, 0.58 pg TEQ/kg/day in the late stage and 1.25 pg TEQ/kg/day in the completed stage. While the daily intakes increase with the weaning progress, they were less than the tolerable daily intake (TDI) of 4 pg TEQ/kg/day for dioxins established in Japan. Dioxins were mainly taken through formula milk in early stage of weaning period, but then were taken through protein-based foods in the subsequent weaning stage.
针对东京都市区婴儿食品中二噁英的膳食摄入量展开了一项研究，二噁英由多氯代二苯并 - 对 - 二噁英（PCDDs）、多氯代二苯并呋喃（PCDFs）和共平面多氯联苯（Co - PCBs）组成。样本包括通过总膳食 - 市场篮子法制备的自制婴儿食品以及通过双份膳食法制备的婴儿食品（主要是商业产品）。在断奶各阶段，若自制婴儿食品和主要商业产品各摄入一半，每千克体重从婴儿食品中摄入二噁英的每日摄入量在早期为0.32 pg TEQ/kg/天，中期为0.45 pg TEQ/kg/天，后期为0.58 pg TEQ/kg/天，完全断奶阶段为1.25 pg TEQ/kg/天。虽然每日摄入量随着断奶进程增加，但低于日本设定的二噁英每日耐受摄入量（TDI）4 pg TEQ/kg/天。在断奶初期，二噁英主要通过配方奶摄入，但在随后的断奶阶段则通过蛋白质类食物摄入。
