The effects of ingested nanosized titanium dioxide (TiO2, anatase, 15 nm) on terrestrial isopods Porcellio scaber (Isopoda, Crustacea) after short-term (three days) dietary exposure were studied. Experiments with terrestrial isopods are suitable for testing the effects of ingested nanoparticles. The experimental design used for dissolved chemicals can be used for nanoparticles, but the presentation of toxicity data needs to be adapted according to the mode of action of nanoparticles and their specific characteristics.

A single-species laboratory test with terrestrial invertebrates was used to identify the hazard of nanosized TiO2. The effects of nano-TiO2 were dependent on exposure concentration and duration, total consumed amount, size and pre-treatment of particles. The intensity of a response was ruled by duration of exposure and not by consumed quantity of nano-TiO2 or exposure concentration as expected. We conclude that the response to nanoparticles is different from that of soluble chemicals therefore these two types of data should be interpreted and processed differently.
