Titanium dioxide nanoparticles in the environment.
Since the 1990s manufacturers have added titanium dioxide to a wide
range of consumer products. So now, it's often found in our waterways. A
new study reports that this nanomaterial can stress photosynthetic
organisms, which could lead to the disruption of nitrogen and carbon
cycles in aquatic ecosystems.
