Three edible mushrooms of the Russulacea family (Lactarius deliciosus, Lactarius sanguifluus, and Lactarius semisanguifluus), most frequently consumed in Serbia, were analyzed using the ICP-OES technique to evaluate the content of K, P, Ca, Mg, Na, Al, As, Cd and Pb, both in cap and stipe. Corresponding soils were analyzed, too. Based on the obtained values for the elemental composition of mushrooms and soil, bioaccumulation and trans-location factors were calculated. All the examined mushrooms species were recognized as bioexclusors of analyzed toxic elements, but bioaccumulators of K, P, and Ca. The studied mushrooms are good sources of macroelements. One portion of 300 g of fresh mushrooms had a significant contribution of K and P, exceeding 15 % of the recommended daily intake for the elements. On the contrary, mushrooms had a low potential to bioaccumulate toxic elements, and presented results indicated the regular consumption of wild edible mushrooms is safe for human health. Correlation analysis was applied to determine phosphorus's influence on the elements' content in the mushrooms and corresponding soils, demonstrating the most remarkable mushrooms' tendency to accumulate phosphorus.

Agaricus Campestris

In Tunisia, many people collect wild edible mushrooms as pickers for their own consumption. The present work aims at contributing to the determination of the chemical composition, non volatile components content (soluble sugars, free amino acids) and minerals and trace elements of three popular Tunisian wild edible mushrooms species collected from the northwest of Tunisia (Agaricus campestris, Boletus edulis and Cantharellus cibarius).All investigated mushrooms revealed that these species are rich sources of proteins (123.70 – 374.10 g kg-1 dry weight (DW)) and carbohydrates (403.3 – 722.40 g kg-1 DW), and low content of fat (28.2 – 39.9 g kg-1 DW); the highest energetic contribution was guaranteed by C. cibarius (1542.71 kJ / 100 g). A. compestris (33.14 mg/g DW) showed the highest concentration of essential amino acids. The composition in individual sugars was also determined, mannitol and trehalose being the most abundant sugars. C. cibarius revealed the highest concentrations of carbohydrates (722.4 g kg-1 DW) and A. compestris the lowest concentration (403.3 g kg-1 DW). Potassium (K) and sodium (Na) are the most abundant minerals in analyzed samples (A. compestris showed the highest concentrations of K and Na, 49141.44 and 9263.886 µg/g DW respectively).

A method for determination of Cr, Fe, Co, Ni, Cu, Zn, Hg and Pb in waters by Energy Dispersive X Ray Fluorescence (EDXRF) was implemented, using a radioisotopic source of 238Pu. For previous concentration was employed a procedure including a coprecipitation step with ammonium pyrrolidinedithiocarbamate (APDC) as quelant agent, the separation of the phases by filtration, the measurement of filter by EDXRF and quantification by a thin layer absolute method. Sensitivity curves for K and L lines were obtained respectively. The sensitivity for most elements was greater by an order of magnitude in the case of measurement with a source of 238Pu instead of 109Cd, which means a considerable decrease in measurement times. The influence of the concentration in the precipitation efficiency was evaluated for each element. In all cases the recoveries are close to 100%, for this reason it can be affirmed that the method of determination of the studied elements is quantitative. Metrological parameters of the method such as trueness, precision, detection limit and uncertainty were calculated. A procedure to calculate the uncertainty of the method was elaborated; the most significant source of uncertainty for the thin layer EDXRF method is associated with the determination of instrumental sensitivities. The error associated with the determination, expressed as expanded uncertainty (in %), varied from 15.4% for low element concentrations (2.5-5 μg/L) to 5.4% for the higher concentration range (20-25 μg/L).
