“…90%) [ 3 ]. It is usually assumed that mushrooms contain predominantly inorganic Hg (more than 90% of the total Hg), and only low amounts of the more hazardous methylmercury, although the available data is still limited [ 4 ]. However, some macrofungal species are known for their ability to accumulate higher concentrations of Hg in their fruit bodies, especially Boletus edulis and its close relatives Boletus pinophilus , Boletus aereus , and Boletus reticulatus , with up to ca.…”

This work describes the development of a novel method for quantitative mapping of Hg and Se in mushroom fruit body tissues with laser ablation coupled to inductively coupled plasma-mass spectrometry (LA-ICP-MS). Different parameters of the protocol for preparation of the standards used for quantification via external calibration were assessed, e.g., the dissolution temperature of gelatin standards and the addition of chitosan and l-cysteine as additives to the gelatin-based calibration droplets to better match the sample matrix. While chitosan was not suited for this purpose, the presence of l-cysteine considerably improved the figures of merit of the calibration, leading to limits of detection of 0.006 and 0.3 µg g−1 for Hg and Se, respectively, at a pixel size of 20 × 20 µm. Further, an in-house reference material, ideally suited for the validation of the method for application to mushroom samples, was successfully prepared from a paste of Boletus edulis. The newly developed method was used to investigate the distribution of Hg and Se in tissue sections of five porcini mushroom individuals of three different species (Boletus edulis, Boletus aereus, and Boletus pinophilus) and one sample of a parasol mushroom (Macrolepiota procera). For one sample, additional areas were ablated at higher spatial resolution, with a laser spot size down to 5 µm, which allows a detailed investigation of the spatial distribution of Hg and Se in mushrooms.

“…Speciation analysis is often applied to foodstuffs and the quantification of Hg species in wild mushrooms has been reported on ref. 149. The Hg species were extracted from dried mushrooms with a 12 g L −1 l -cysteine solution and UAE for 40 min at 40 °C followed by centrifugation and filtration before injection on to an HPLC-ICP-MS system.…”

“…Speciation of toxic elements in mushrooms was reported in two papers . Zou et al 174 looked at Hg species whilst Komorowicz et al 46 focussed on As speciation. For Hg speciation HPLC-ICP-MS was employed to determine iHg as well as MeHg, EtHg and PhHg species in wild mushrooms.…”
