Although the metabolic effects of benzo(a)pyrene have been investigated extensively in rodents, little is known about its effects in the terrestrial environment and nothing is known about its effects on soil invertebrates. In this study, the authors have chosen the woodlouse Porcellio scaber (Latr.) (Crustacea, Isopoda) as a representative from the soil invertebrate community. Experiments were designed to analyze the consequences of benzo(a)pyrene exposure for the energy metabolism. The partitioning of energy between respiration and scope for growth is considered as an ecologically relevant criterion for studying effects of contaminants in the environment. PAH might affect this partitioning by inducing biotransformation reactions that make demands on the assimilated energy.
