Mechanisms of phenanthrene toxicity in the soil invertebrate Enchytraeus crypticus

ABSTRACT: Polycyclic Aromatic Hydrocarbons (PAHs) continue to cause environmental challenges due to their release in the environment by a great variety of anthropogenic activities and their accumulation in soil ecosystems. Here we studied the toxicological effect of the model PAH phenanthrene (Phe) on the soil invertebrate model Enchytraeus crypticus at the individual, tissue and molecular level. Organisms were exposed to Phe for 2 and 21 days to the (previously estimated) EC10 and EC50 (population reproduction over 3 weeks). Gene expression profiling did not reveal a typical Phe-induced biotransfor-mation signature, as it usually does in arthropods and vertebrates. Instead, we observed only general metabolic processes to be affected after 2 days of exposure, such as translation and ATP synthesis-co
