Assessing the Potential of Forest Stands for Ectomycorrhizal Mushrooms as a Subsistence Ecosystem Service for Socially Disadvantaged People: A Case Study from Central Slovakia

Blusher mushroom (Amanita rubescens Pers.): A Study of Mercury Content in Substrate and Mushroom Samples from Slovakia with Respect to Locality and Developmental Stages

The edible mushroom Amanita rubescens Pers., regularly collected and consumed in Slovakia, was assessed for health risk due to the mercury content in its fruiting body parts. For this purpose, 364 both from the soil/substrate and mushroom samples from 40 localities in Slovakia were evaluated. At the same time, 21 samples of 7 developmental stages of the fruiting body of A. rubescens were taken in the Žakýlske pleso locality. The total mercury content in the soil and mushroom samples was determined using an AMA-254 analyzer. The contamination factor (Cf) and index of geoaccumulation (Igeo) were used to detect the level of soil pollution by mercury. The ability of A. rubescens to accumulate mercury from the soil environment was evaluated using the bioconcentration factor (BCF), and the distribution of mercury in the mushroom body was evaluated using the translocation quotient (Qc/s). To determine the health risks resulting from mushroom consumption, the percentages of provisional tolerable weekly intake (%PTWI) and target hazard quotient (THQ) were used. The obtained results have confirmed serious content of mercury soil pollution, especially in former mining areas, where the situation is alarming from a health risk point of view. Consumption of A. rubescens was found to be risky, not only in former mining areas, but higher values of mercury were also detected in other parts of Slovakia. Evaluation of the developmental stages of the fruiting body of A. rubescens showed that the highest bioconcentration factor was determined at developmental stage no. VI for caps with a value of 2.47 mg kg-1 and developmental stage VII for stipes with a value of 1.65 mg kg-1 DW.

Exploring Consumer Behavior and Preferences towards Edible Mushrooms in Slovakia

Edible mushrooms represent a food with high nutritional properties, and their consumption has a positive effect on the health of consumers. The aim of the paper is to identify the behavior and preferences of consumers in the consumption of edible mushrooms in Slovakia. The aim of the paper was achieved by conducting a consumer survey using the snowball sampling method on a sample of 1166 respondents in the Slovak Republic, of which 1032 respondents were consumers of edible mushrooms. Using statistical methods (the Chi-square test of independence, Kruskal-Wallis H test, and Friedman test, as well as categorical principal component analysis), differences in consumer behavior were examined in three identified segments created based on the amount of consumption of edible mushrooms. The results of the consumer study showed the existence of statistically significant differences between the defined segments in terms of frequency of consumption, evaluation of the preference of edible mushrooms in various meals, evaluation of important reasons for consumption, and determination of preference for individual species of mushrooms, as well as determination of preference for the place of consumption and the option of obtaining mushrooms for consumption. Moreover, four latent components determining the purchase of mushrooms applicable in all segments were defined. Supporting the consumption of edible mushrooms among Slovak consumers is possible by increasing consumer awareness through recommendations and published articles. The research paper provides a new insight into the behavior and preferences of consumers in mushroom consumption, divided into three segments, which can fill the scientific research gap. The results provide valuable information for scientific purposes, as well as for food companies and policy makers.
