Knowledge of nanomaterial toxicity is critical to avoid adverse effects on human and environment health. In this study, the influences of crystal morphology on physico-chemical and toxic properties of nanoscale TiO 2 ( n -TiO 2 ) were investigated. Artemia salina were exposed to anatase, rutile and mixture polymorphs of n -TiO 2 in seawater. Short-term (24 h) and long-term (96 h) exposures were conducted in 1, 10 and 100 mg/L suspensions of n -TiO 2 in the presence and absence of food. Anatase form had highest accumulation followed by mixture and rutile. Presence of food greatly reduced accumulation. n -TiO 2 dissolution was not significant in seawater (p&lt;0.05) nor was influenced from crystal structure. Highest toxic effects occurred in 96h exposure in the order of anatase &gt; mixture &gt; rutile. Mortality and oxidative stress levels increased with increasing n -TiO 2 concentration and exposure time (p&lt;0.05). Presence of food in the exposure medium alleviated the oxidative stress, indicating that deprivation from food could promote toxic effects of n -TiO 2 under long-term exposure.
