abstractLeadcontentwasdeterminedin238samplesof28speciesofediblemushroomscollectedfromdifferent sites in the province of Lugo (NW Spain) during 2005 and 2006. The hymenophore (H) and the rest of the fruiting body (RFB) were analysed separately. The analyses were carried out by an anodic stripping voltammetric technique using drop mercury as the working electrode. The highest mean lead contents (mg/kg dry weight) of 3.6 and 4.1, 3.0 and 2.2, 2.5 and 2.3, 2.4 and 2.3 were determined in Coprinus comatus,Agaricuscampestris,LepistanudaandCalvatiautriformisinhymenophoreandtherestoffruiting bodies,respectively,whilethelowestinAgaricusbisporus(0.35inHand0.54inRFB)andFistulinahepatica (0.41 in H and 0.50 in RFB). All mushroom species were bioexclusors of lead (BCF<1) in relation to the underlyingsoils.Therewerenotstatisticallysignificantdifferencesbetweenleadlevelsinhymenophore andintherestofthefruitingbodies.Theleadconcentrationswerecomparedtoliteraturedataandlevels set by legislation. It can be concluded that the consumption of these mushrooms can not be considered as a toxicological risk from lead content point of view, and they provide a nutritional requirement to the diet.
