Twelve selected food plants were grown in greenhouse pots to determine the relative concentration of Cd and Zn in the plants grown in sludge‐treated soils. The relative concentration of the metal was calculated as the quotient of the metal content in a plant and that in Swiss chard [ Beta vulgaris subsp. cicla (L.) Koch] grown under the same soil conditions. The relative concentrations of Cd and Zn of food plants grown in several sludge‐treated soils were significantly different ( p < 0.01), but the relative concentrations of these plants in one soil has the statistical characteristics (e.g., range, mean, median, coefficient of variation, etc.) as those in another soil.
