Abstrakt: This study assessed health risks of pollutants through oral exposure from the perspective of the coexistence of multiple uncertainties with integrated approaches. These approaches included the actual survey population exposure parameters, coupled with fuzzy mathematical theory to calculate the model parameters. While reducing uncertainty, the research attempted to maximize the accuracy and immediacy of risk assessment, thus providing a theoretical guidance for pollution prevention and control and food safety in the target area. The results show that the organic pollutants of PAEs (DEP, DBP, DNOP, BBP, DEHP) have different contamination levels. In addition, non-carcinogenic risk levels are higher than the acceptable ones of 1x10-6 and 1x10-4, recommended by Royal Society and US EPA except soil intake. [ABSTRACT FROM AUTHOR]
