Abstract

Bioaccumulation of potentially toxic metals by litter-feeding invertebrates is determined not only by the concentration of metal in the diet, but also by the flux of food through the body. Nitrogen and phosphorus are the main elements regulating food consumption and so are expected to affect the bioaccumulation of trace elements such as cadmium. To test this idea, we applied a three-factor orthogonal experimental design to estimate the effects of nitrogen, phosphorus and cadmium additions to the food on cadmium accumulation by the terrestrial isopod Porcellio scaber. Cd, N and P were added to milled poplar litter in concentrations of 0, 10 and 20 μg g
