“…The analysed mushroom samples had an average Fe concentration of 81.51±2.81 mg kg-1, which was above the safe limit of 15 mg kg -1 set by WHO [33] while substrate Fe content ranged from 62.06±1.05 mg kg -1 from Ubakala to 98.23±2.69 mg kg -1 from Ohiya site 1. According to findings in publications until 1999, reported Fe content of mushrooms was found to vary between 30.0 and 150.0 mg kg -1 [12]. Similarly, Fe contents in mushroom samples, over the recent years, have been reported in the range of 101.6-543.8 mg kg -1 [20], 1322.4-1596.0 mg kg -1 [38], 43.7-65.1 mg kg -1 [39], 44.4-125.1 mg kg -1 [40], and 8.25-58.25 mg kg -1 [29], 74.08-123.40 mg kg-1 [5].…”

“…For contaminants with a potential to build up in the body over time such as mercury, lead, and cadmium, the provisional tolerable weekly intake (PTWI) is used as reference values in evaluating the risks of intake of such toxic metals from food consumption. It has been reported that the accumulation of some elements in mushrooms is affected by environmental and fungal factors and this is well documented for mushrooms growing in soils polluted with Hg, Cd, Pb, As or radioactive cesium [12]. The developmental stage of mushroom (fruit body) can also highly matter in view of exposure of the consumer for certain elements, e.g., radioactive cesium, while certain seem to be regulated by fungus and not change (decrease or increase), which can be relevant for specific consumers [13].…”

ABSTRACT. The bioaccumulation of trace metals in mushrooms poses a health risk to consumers. Despite the fact that mushroom eating has been linked to numerous health advantages, little attention has been paid to the relative health risks associated with trace metal build-up in this nutritional source in Nigeria. Pb, Cd, Fe, Hg and As in Pleurotus tuber-regium collected from mechanic workshops in Umuahia were analysed and the associated health risks for the consumers were evaluated. The trace metal contents in the mushroom and its substrates showed a descending order of Fe > Pb > Cd > As > Hg. The heavy metals concentration ranges in fruity body of the Pleurotus tuber-regium were Fe (62.16-98.17 mg kg-1), Pb (0.18-1.21 mg kg-1), Cd (0.05-0.34 mg kg-1), As (0.25-0.51 mg kg-1) and Hg (0.009-0.021 mg kg-1). The estimation of weekly intake values was lower than PTWIs of mushroom species except for Fe. According to the THQ and the HI calculations for trace metal contents in the mushrooms, mercury did not pose any risk on human health; whereas the other determined trace metals gave THQ values of 1 < THQ < 10 and showed the possibility of long-term risk.

The objective of this study is to better quantify the occurrence, intake, and potential risk from Hg in fungi traditionally foraged in SW China. The concentrations and intakes of Hg were measured from 42 species including a “hard” flesh type polypore fungi and a” soft” flesh type edible species that are used in traditional herbal medicine, collected during the period 2011–2017. Three profiles of forest topsoil from the Zhenyuan site in 2015 and Changning and Dulong sites in 2016 were also investigated. The concentrations of Hg in composite samples of polypore fungi were usually below 0.1 mg kg−1 dry weight (dw) but higher levels, 0.11 ± 0.01 and 0.24 ± 0.00 mg kg−1 dw, were noted in Ganoderma applanatum and Amauroderma niger respectively, both from the Nujiang site near the town of Lanping in NW Yunnan. Hg concentrations in Boletaceae species were usually well above 1.0 mg kg−1 dw and as high as 10 mg kg−1 dw. The quality of the mushrooms in this study in view of contamination with Hg showed a complex picture. The “worst case” estimations showed probable intake of Hg from 0.006 μg kg−1 body mass (bm) (“hard” type flesh) to 0.25 μg kg−1 bm (“soft” flesh) on a daily basis for capsulated products, from 17 to 83 μg kg−1 bm (“soft” flesh) in a meal (“hard” type flesh mushrooms are not cooked while used in traditional herbal medicine after processing), and from 0.042 to 1.7 and 120 to 580 μg kg−1 bm on a weekly basis, respectively. Graphical abstract Key points • Polypore species were slightly contaminated with Hg. • Hg maximal content in the polypore was < 0.25 mg kg−1dry weight. • Many species from Boletaceae family in Yunnan showed elevated Hg. • Locals who often eat Boletus may take Hg at a dose above the daily reference dose.
