Sažetak
Accumulation, distribution and bioconcentration potential of mercury (Hg) by mushrooms of Tricholoma equestre, T. portentosum, T. columbeta and T. terreum collected from regions within Central and South Eastern Europe are presented. In total, 121 fruiting bodies and 96 soil samples were analyzed. The mercury contents was determined by AAS mercury analyzer. The Hg content varied from 0.10 ± 0.06 to 0.71 ± 0.34 mg kg−1 dry matter for caps and from 0.04 ± 0.02 to 0.38 ± 0.13 mg kg−1 dry matter in stems. The Hg content of the soil substratum (0–10 cm layer) underneath the fruiting bodies were different depending on the sampling site and varied from 0.009 to 0.046 mg kg−1 dry matter with mean values varying from 0.013 ± 0.003 to 0.028 ± 0.006 mg kg−1 dry matter. Results showed generally low levels of mercury, both, in Tricholoma mushroom species and forest topsoil for investigated locations. In terms of the anatomical parts of the fruiting body (cap-stem), a considerably greater concentration of the mercury was found in the caps than the stems at ratio between 1.6 ± 0.6 and 3.9 ± 1.8. The calculated bioconcentration factors (BCF) showd that all of the mushrooms can be regarded as a mercury bioaccumulator. The T. equestre mushroom species showed moderate ability to accumulate Hg with bioconcentration factor (BCF) values ranging from 18.0 ± 7.0 to 37 ± 18. The consumption of analyzed mushroom species from background areas in the Central and South Eastern Europe, can be considered safe from a toxicological point of view because the determined concentrations of mercury are below the provisional weekly tolerance limit (PTWI) of 0.004 mg kg−1 body mass. These data are important in view of toxicology, food chemistry and environmental protection.
