9.15 Toxic Mushrooms? Cadmium, a heavy metal, is toxic to ani- mals. Mushrooms, however, are able to absorb and accumulate cad- mium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and pub- lished the results in the paper "Influence of Some Factors in Toxi- city and Accumulation of Cd from Edible Wild Macrofungi in NW Spain" (Journal of Environmental Science and Health, Vol. B33(4), pp. 439-455). A hypothesis test is to be performed to decide whether the mean cadmium level in Boletus pinicola mushrooms is greater than the government's recommended limit.
