The lead and cadmium content of 89 samples of some edible mushrooms, corresponding to 8 different species, were determined by atomic absorption spectrophotometry to evaluate the importance of mushrooms as a dietary source of both elements. Lead content of the selected mushrooms ranged from less than 0.058 to 1.85 mg/kg, whereas cadmium content varied from 0.01 to 5.55 mg/kg. The levels found differed significantly (p 0.001) between species. The samples of Psalliota campestris showed the highest levels with respect to the remainder of the species analyzed. The concentration levels were compared to literature data and the contribution of mushrooms to the daily intake of both elements in Spain was calculated. At the same time the possible health risk for the consumer is pointed out.
