The aim of study was to determine the phytoextraction of rare earth elements (REEs) to roots, stems and leaves of five herbaceous plant species ( Achillea millefolium L., Artemisia vulgaris L., Papaver rhoeas L., Taraxacum officinale and Tripleurospermum inodorum), growing in four areas located in close proximity to a road with varied traffic intensity. Additionally, the relationship between road traffic intensity, REE concentration in soil and the content of these elements in plant organs was estimated. A. vulgaris and P. rhoeas were able to effectively transport REEs in their leaves, independently of area collection. The highest content of REEs was observed in P. rhoeas leaves and T. inodorum roots. Generally, HREEs were accumulated in P. rhoeas roots and leaves and also in the stems of T. inodorum and T. officinale, whereas LREEs were accumulated in T. inodorum roots and T. officinale stems. It is worth underlining that there was a clear relationship between road traffic intensity and REE, HREE and LREE concentration in soil. No positive correlation was found between the concentration of these elements in soil and their content in plants, with the exception of T. officinale. An effective transport of REEs from the root system to leaves was observed, what points to the possible ability of some of the tested plant species to remove REEs from soils near roads.

MUSHROOMS ,COPPER content of food ,PLANT species ,FOOD consumption - Abstract
The aim of the study was to estimate copper (Cu) accumulation efficiency in whole-fruiting bodies of 18 edible and non-edible wild growing mushrooms collected from 27 places in the Wielkopolska Voivodeship. Mushrooms were collected each time from the same places to estimate the diversity in Cu accumulation between tested mushroom species within 3 consecutive years of study (2011–2013). The study results revealed various accumulation of Cu in the whole-tested mushroom fruiting bodies. The highest mean accumulation of Cu was observed inMacrolepiota procera(119.4 ± 20.0 mg kg−1dm), while the lowest was inSuillus luteusandRussula felleafruiting bodies (16.1 ± 3.0 and 18.8 ± 4.6 mg kg−1dm, respectively). Significant differences in Cu accumulation between mushroom species collected in 2011 and in the two following years (2012 and 2013) were observed. The results indicated that sporadic consumption of these mushrooms was not related to excessive intake of Cu for the human body (no toxic influence on health). [ABSTRACT FROM PUBLISHER]

BOLETUS ,FRUITING bodies (Fungi) ,SOIL pollution ,PLANT-soil relationships ,PLANT species - Abstract
The aim of the study was to analyse levels of 17 trace elements and 5 major minerals in 11Boletus badiusfruiting bodies able to grow in extremely polluted waste (flotation tailings) and polluted soil in southern Poland. The presented data widen the limited literature data about the abilities of wild-growing mushroom species to grow on heavily contaminated substrates. Content of elements in waste, soil and mushrooms was analysed by flame atomic absorption spectrometry (FAAS) and cold vapour atomic absorption spectrometry (CVAAS - Hg). The industrial areas differed greatly as regards the content of elements in flotation tailings and soil; therefore differences in Ag, Ba, Cd, Co, Fe, Mo, Ni, Pb, Ca, K, Mg, Na and P accumulation in mushrooms were observed. The highest contents of elements in mushrooms were observed for: As, Al, Cu and Zn (86 ± 28, 549 ± 116, 341 ± 59 and 506 ± 40 mg kg−1dry matter, respectively). Calculated bioconcentration factor (BCF) values were higher than 1 for Al (15.1–16.9), Fe (10.6–24.4) and Hg (10.2–16.4) only. The main value of the presented results is the fact that one of the common wild-growing mushroom species was able to grow on flotation tailings containing over 22 g kg−1of As and, additionally, effective accumulation of other elements was observed. In view of the high content of the majority of analysed elements in fruiting bodies, edible mushrooms from such polluted areas are nonconsumable. [ABSTRACT FROM AUTHOR]

BIOACCUMULATION ,MUSHROOMS ,BOLETUS edulis ,BIOCONCENTRATION - Abstract
The contents of 16 minerals and trace elements (Ag, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Ni, Pb, Pt, Ti and Zn) were analyzed in edible mushrooms (Leccinum scabrum,Boletus edulisandBoletus badius) collected in southwest Poland. Content of Co, Ni and Pb was similar in all tested mushroom species, while content of Ag, Ca, Cd, Hg and Ti was significantly higher inB. edulisthan inL. scabrumandB. badius. The largest differences between these species were observed for Fe and Zn accumulation. The highest contents of these elements were noted inB. badiusbodies (202 ± 88 and 137 ± 24 mg kg−1dry matter, respectively), lower inB. edulis(131 ± 99 and 89 ± 26 mg kg−1dry matter, respectively) and lowest inL. scabrum.Differences in As, Cu and Cr content between tested species were observed mainly betweenL. scabrumandB. badiusfruiting bodies. Content of Pt was below 0.01 mg kg−1dry matter). In the case of Mg and Mn accumulation, differences betweenB. edulisandB. badiuswere not observed (478 and 440 mg kg−1dry matter for Mg and 23 and 19 mg kg−1dry matter for Mn), and the results showed significantly higher content of these elements than inL. scabrumbodies (312 and 10 mg kg−1dry matter, respectively). It is worth underlining that clear accumulation shown by the bioconcentration factor (BCF>1) observed for all three mushroom species was noted in the case of elements Ag, Cd, Co, Cu, Hg, Ni and Zn only.

The aim of the study was to evaluate the possibility of supplementation with inorganic forms of selenium (Na2SeO4and Na2SeO3) in concentrations of 0, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0 and 1.5 mM of three medicinal mushroom species:Agrocybe aegerita,Hericium erinaceusandGanoderma lucidum. Tested mushroom species grew in Se additions of 0–0.6 mM (A. aegeritaandH. erinaceus), while growth ofG. lucidumbodies was observed for 0–0.8 mM. For the latter mushroom species, the total Se content was the highest. Content of Seorgwas diverse; for control bodies it was the highest forG. lucidum(only organic forms were present), lower forA. aegerita(84% organic forms) and the lowest forH. erinaceus(56% organic forms). Accumulation of Se(IV) was generally significantly higher than Se(VI) for all tested mushroom species. There was no significant decrease ofA. aegeritaorG. lucidumbiomass with the exception ofG. lucidumbodies growing under 0.8 mM of Se species addition (15.51 ± 6.53 g). Biomass ofH. erinaceusbodies was the highest under 0.2 (197.04 ± 8.73 g), control (191.80 ± 6.06 g) and 0.1 mM (185.04 ± 8.73 g) of both inorganic salts. The addition to the medium of Se salts brought about macroscopic changes in the fruiting bodies of the examined mushrooms. Concentrations exceeding 0.4 mM caused diminution of carpophores or even their total absence. In addition, colour changes of fruiting bodies were also recorded. At Se concentrations of 0.4 and 0.6 mM,A. aegeritafruiting bodies were distinctly lighter and those ofH. erinaceuschanged colour from purely white to white-pink. [ABSTRACT FROM PUBLISHER]
