Cadmium in Chinese Postharvest Peanuts and Dietary Exposure Assessment in Associated Population.
Cadmium (Cd) in 8698 peanut samples collected from China in 2009-2014 was studied to evaluate its contamination level, distribution, and health risk. The average Cd concentration was 0.1684 mg kg-1; the range of 2.5-97.5% was 0.0191-0.4762 mg kg-1, indicating the cadmium-contaminated peanut level was even lower. Some peanut strains for which protein contents had a significant correlation (Pearson correlation coefficient r = 0.86**) with the Cd concentration level should be of concern. Under the same soil Cd background, the difference in Cd contents in different peanut varieties is extremely significant. For example, the Cd concentration of Silihong is about 0.4522 mg kg-1, being 7 times higher than that of Zhonghua 6. According to the exposure assessment using the probabilistic simulation method, the target hazard quotients (THQs) of all groups should be below 1. The THQ range in this study was from 0.0035 to 0.0202, suggesting that there were no potential noncinogenic effects in any group.
