Abstract
Data on multi-trace element composition and content relationships have been obtained for Cantharellus cibarius, C. tubaeformis, and C. minor mushrooms from Poland and China by inductive coupled plasma–dynamic reaction cell–mass spectroscopy. There is no previous data published on As, Li, V, Tl, and U in chanterelles from Poland and on Ba, Co, Cr, Ni, Rb, and Sr in chanterelles from China. The results implied a role of the soil background geochemistry at the collection site with the occurrence of Ag, As, Ba, Cr, Cs, Li, Mn, Pb, Rb, Sr, U, and V in the fruiting bodies. Both geogenic Cd and anthropogenic Cd can contribute in load of this element in chanterelles from the Świetokrzyskie Mts. region in Poland, while geogenic source can be highly dominant in the background areas of Yunnan. An essentiality of Cu and Zn and effort by mushroom to maintain their physiological regulation could be reflected by data for Cantharellus mushrooms from both regions of the world, but its geogenic source (and possibly anthropogenic) can matter also in the region of the Świetokrzyskie Mountains in Poland. The elements Co, Ni, and Tl were at the same order of magnitude in contents in C. cibarius in Poland and Yunnan, China. C. tubaeformis differed from C. cibarius by a lower content of correlated Co, Ni, and Zn. Soil which is polymetallic and highly weathered in Yunnan can be suggested as a natural geogenic source of greater concentrations of As, Ba, Cr, Li, Pb, Sr, U, and V in the chanterelles there while lower of Mn and Rb, when related to chanterelles in Poland. A difference in Cs content between the sites can be attributed as an effect of the 137Cs release from the Chernobyl accident, in which Poland was much more affected than Yunnan, where deposition was negligible.
Highlights
Mushrooms from the genus Cantharellus are well recognizable and are a popular food item in many regions of the world, e.g., C. cibarius Fr
This study aimed to update information on the content of some essential and hazardous metallic elements accumulated in Cantharellus mushrooms foraged in Poland and China as determined by inductively coupled plasma mass spectroscopy with a dynamic reaction cell (ICP-DRC-MS)
Ten composite samples of fruiting bodies of the mushroom C. cibarius Fr. were collected from the following sites: Jastrzebia Góra (CC-1), Darżlubska (CC-2), Kościerzyna forests (CC-3), Tuchola Pinewoods–Osiek (CC-4), and Tuchola Pinewoods (CC-5) in the Pomerania region; Ciechocinek (CC-7) in the Kujawy region; Poznań outskirts (CC-8) in Great Poland Voivodship; Bobrowniki (CC-6) in the Podlasie region; Pieszków (CC-10) in the Świętokrzyskie region; and Głogów Małopolski (CC-11) in Little Poland Voivodship of Poland in 2012–2014; one shipment was bought in a shop in Poland (CC-9) and another one was collected from the region of Yuxi county (CC-12) in the province of Yunnan in China in 2013
Summary
Mushrooms from the genus Cantharellus are well recognizable and are a popular food item in many regions of the world, e.g., C. cibarius Fr. Wildgrowing mushrooms without doubt are important organic food items in the diet of many people, while our knowledge on their mineral constituent composition and content, and their fate during culinary processing and their accessibility, has many gaps. In a study of wild-growing mushrooms, it is Environ Sci Pollut Res (2017) 24:11472–11482 important to better understand their mineral constituent composition in the context of the best analytical chemistry, the natural geochemistry of the soil substratum where the mycelium grows as well as the physiology of a species (Aloupi et al 2011; Falandysz et al 2012a, b; Kojta and Falandysz 2016; Kojta et al 2015; Kubrová and Borovička 2015; Mleczek et al 2016; Nearing et al 2014; Tel et al 2014). Available data on the baseline content of the geogenic metallic elements and metalloids in soils from the background areas in Yunnan as well as a geogenic and anthropogenic sources in Poland can explain results obtained for chanterelle mushrooms
