Abstract
|
|
|
|
Polycyclic aromatic hydrocarbons(PAHs) contents were analyzed by measuring benz(a)anthracene(BaA), chrysene(Chr), benzo(b)fluoranthene(BbF) and benzo(a)pyrene(BaP), and the related risk characterization was conducted for 113 samples out of 14 different agricultural products used for food and medicine. Detection rate of PAHs was 90.3% as a whole, and the highest one was 80.5% for BaP. The detection rate of BaP exceeding the maximum permitted concentration of Rehmanniae Radix Preparata and Rehmanniae Radix, 5.0 μg/kg was 1.8%, and the detection rates of BaA, Chr and BbF were within the range of 2.7~10.6%. The highest average concentration of BaA was 3.41 μg/kg detected from Lycii Fructus, while those of Chr, BbF, BaP and PAH4(sum of detected BaA, Chr, BbF and BaP) were 5.00, 1.79, 2.36, 12.36 μg/kg, respectively, detected from Rehmanniae Radix Preparata. As for the risk characterization on PAHs, the overall MOE(Margin of Exposure) values were measured within the range of 105~107, which is unlikely to cause direct health concerns, but the worring values of MOE were measured 6.57×104 for BaP and 6.10×104 for PAH4 from Rehmanniae Radix Preparata, which may require an improvement plan to reduce BaP contents.
