Altered physiological conditions of the terrestrial isopod Porcellio scaber as a measure of subchronic TiO2 effects.

Titanium dioxide nanoparticles (nano-TiO2) show low toxic potential against a variety of environmental organisms when measured by conventional toxicity endpoints. However, the question is whether the conventional measures of toxicity can define the adverse effects of nanoparticles. The aim of this study was to asses the potential toxic and cytotoxic effects of the ingested nano-TiO2 (anatase, <25 nm) on a terrestrial isopod, Porcellio scaber.
