Temperature-Dependent Toxicokinetics of Phenanthrene in <i>Enchytraeus albidus</i> (Oligochaeta)

Although the toxicokinetics of organic pollutants in soil invertebrates under optimal and constant temperature has been widely reported, their uptake, elimination, bioaccumulation suboptimal temperatures, especially daily fluctuating (FT) regimes have received only little research attention. In this study, phenanthrene (PHE) Enchytraeus albidus (Oligochaeta) different an FT regime were investigated a natural soil. general, PHE concentrations worm tissues reached steady state within 14 days at temperatures. The uptake (ku) elimination (ke) rate constants increased with increasing likely because diffusivity into worms metabolic rate. Interestingly, factor E. showed positive relationship slope ku-temperature was larger than that ke-temperature relationship. Further, average temperature. These findings suggest that, climatic conditions, should be considered for assessment terrestrial organisms.
