TiO₂ nanoparticles affect the bacterial community structure and Eisenia fetida (Savigny, 1826) in an arable soil.

ABSTRACT: The amount of nanoparticles (NP), such as TiO₂, has increased substantially in the environment. It is still largely unknown, however, how NP might interact with earthworms and organic material and how this might affect the bacterial community structure and their functionality. Therefore, an arable soil was amended with TiO₂ NP at 0, 150 or 300 mg kg^-1 and subjected to different treatments. Treatments were soil amended with ten earthworms (Eisenia fetida (Savigny, 1826)) with fully developed clitellum and an average fresh mass of 0.5 to 500 g dry soil, 1.75 g tyndallized Quaker^® oat seeds Avena sativa (L.) kg^-1, or earthworms plus oat seeds, or left unamended. The bacterial community structure was monitored throughout the
