Outline
To evaluate the content characteristics of lead (Pb), cadmium (Cd) and mercury (Hg) in 18 kinds of edible fungi species from Guizhou Province, as well as the impacts of their bioaccessibility on dietary risks.
Physiologically based extraction test (PBET) was employed to simulate gastrointestinal digestion.Concentration data of the 3 kinds of heavy metals before and after extraction were substituted into a health risk assessment model to quantify changes in their content during the digestive process.
The concentration ranges of the 3 kinds of heavy metals, Pb, Cd and Hg, were 0.0116–0.4575, 0.0031–0.7749 and 0–0.0264 mg/kg,respectively. After incorporating the bioaccessibility data, the ranges decreased to 0–0.1942, 0–0.4548 and 0–0.0187 mg/kg, respectively. Meanwhile, the mean values of the estimated daily intake (EDI) were reduced by 39.05%,55.25% and 80.69%, respectively, and the mean values of the target hazard quotient (THQ) and target cancer risk(TCR) were decreased by 39.05%, 55.25% and 77.03%, respectively, with the same reduction rates observed in both adults and children.
The edible mushroom samples in this batch exhibit a certain degree of heavy metal contamination. However, after simulated gastrointestinal digestion, the results of health risk assessment are further reduced. Special attention should be paid to heavy metal contamination in Lentinus edodes, Agaricus blazei,Morchella esculenta and Dictyophora indusiata. Notably, the dietary health risks to children deserve more attention compared to adults.
