中文摘要:本文通过对消费者两天农药残留摄入量的详细估算来展示确定性模型输入参数暴露评估的联合不确定性对量化不确定性贡献,一个体重60KG的报告人第一天和第二天的联苯菊酯残留的每日摄入量分别为0.00257 mg/kgbw和0.00281 mg/kgbw,联合不确定性为27-28%,主要贡献者是水果和全餐面包,而联合不确定性的各阶段的贡献取决于特定的食物。总之,在估计每日膳食暴露联合不确定性时,食谱的变化、消费品质量的估计、原材料的取样和加工、农药残留分析影响力最大但依次减弱。
外文摘要:The sources of quantitative and qualitative uncertainties of the exposure of a consumer to a pesticide residue are identified. The contribution of quantifiable uncertainties of input parameters of deterministic model to the combined uncertainty of the estimated exposure is shown with detailed calculation using the pesticide residue content of food consumed during two days. The daily intakes of bifenthrin residues calculated for the 60 kg bodyweight of the reporting person are 0.00257 mg/kgbw and 0.00281 mg/kgbw for day 1 and day 2, respectively with 27-28% combined uncertainty. The major contributors were fruits and whole meal bread. The contribution of the individual steps to the combined uncertainty depends on the particular food item. In general, the variability of recipes, estimation of the mass of consumed food, sampling, processing of raw commodities and analysis of pesticide residues influenced most, in decreasing order, the combined uncertainty of the estimated daily exposure.
