Deterministic risk assessment of OTA in dark tea. Average-intake consumers: average tea consumption, heavy-intake consumers: 95th percentile of tea consumption. LB (lower bound) indicates that 0 was used as the contamination value for undetected samples in the risk assessment. MB (middle bound) indicates that the 1/2 LOD value of the corresponding study was used as the contamination value for undetected samples in the risk assessment. UB (upper bound) indicates that the LOD value of the corresponding study was used as the contamination value for undetected samples in the risk assessment. AVE, the average contamination value in this study, was selected as the contamination value for the extreme-case risk assessment. Max, the maximum contamination value in this study, was selected as the contamination value for terrible case risk assessment. Values with bold font are the maximal HQ to each comparison group.
