Abstract
Levels of 12 trace elements were measured in samples of the bryophyte Hypnum cupressiforme Hedw. and in soil collected in the sorroundings of an oil-fired power plant in Northern Italy. Metal bioaccumulation in moss was estimated after soil correction in order to obtain deposition patterns and individuate potentially toxic metals emitted from the plant. V and Ni, occurring together in fuel oil, showed highest bioaccumulation values near the stacks. Mean contamination of the study area for these elements is 5.5 (V) and 3.3 (Ni) times the background levels of the reference site. Other elements showed only limited alterations of bioaccumulation values, in relation to agricultural and industrial activity in the study area.
