Nano form of titanium dioxide can be toxic to marine organisms
Date:1/24/2012

se found in nature, can induce toxicity of TiO2 nanoparticles to marine phytoplankton, the most important primary producers on Earth.

"With no exposure to UVR, the TiO2 had no effect on phytoplankton, but under low-intensity UVR, ROS in seawater increased with increasing concentrations of nano- TiO2."

The concern is that rising concentrations of nano- TiO2 "may lead to increased overall oxidative stress in seawater contaminated by TiO22, and cause decreased resiliency of marine ecosystems."

The authors suggest, therefore, that UVR exposure should be considered when conducting experiments to determine the ecotoxicity of nanomaterials having photoactive potential.
