The World Health Organization recommends assessing human exposure to contaminants on a regular basis. In order to assess the current dietary exposure of the Belgian adult population to PCDD/Fs and dioxin-like PCBs and to update exposure estimates of 2000-2001, a total diet study was designed. The mean dietary intake of PCDD/Fs and dioxin-like PCBs in the Belgian adult population in 2008 was estimated to be 0.72pgTEQkgbw(-1)d(-1) (middle bound concentrations, TEF of 1998) based on occurrence data of 2008 and national food consumption data of 2004. This value is clearly below the Tolerable Weekly Intake (TWI) of 14pgTEQkgbw(-1)week(-1) set by the Scientific Committee on Food of the European Commission and below the provisional tolerable monthly intake of 70pgTEQkgbw(-1)month(-1) set by the Joint FAO/WHO Expert Committee on Food Additives. Considering the cumulative distribution, the intake was less than 1pgTEQkgbw(-1)d(-1) for more than 80% of the population, and less than 2pgTEQkgbw(-1)d(-1) for the entire population. When using the 2005 TEF instead of the 1998 TEF, the mean dietary intake in the Belgian adult population was estimated to be 0.61pgTEQkgbw(-1)d(-1).
世界卫生组织建议定期评估人类接触污染物的情况。为了评估比利时成年人目前对 PCDD/Fs 和类二恶英多氯联苯的饮食暴露情况，并更新 2000-2001 年的暴露估计值，设计了一项总膳食研究。根据 2008 年的发生数据和 2004 年的国家食物消费数据，估计 2008 年比利时成年人的 PCDD/Fs 和类二恶英多氯联苯的平均膳食摄入量为 0.72pgTEQkgbw(-1)d(-1)(中值浓度，TEF 为 1998 年)。这个值明显低于欧盟食品安全委员会科学委员会设定的 14pgTEQkgbw(-1)week(-1)可耐受每周摄入量（TWI），也低于粮农组织/世界卫生组织食品添加剂联合专家委员会设定的 70pgTEQkgbw(-1)month(-1)暂定可耐受每月摄入量。考虑到累积分布，80%以上的人口的摄入量低于 1pgTEQkgbw(-1)d(-1)，而所有人的摄入量均低于 2pgTEQkgbw(-1)d(-1)。当使用 2005 年 TEF 而不是 1998 年 TEF 时，估计比利时成年人的平均膳食摄入量为 0.61pgTEQkgbw(-1)d(-1)。
