Use of titanium dioxide nanoparticles (TiO 2 NPs) has become a part of our daily life and the
high environmental concentrations predicted to accumulate in aquatic ecosystems are …

A number of studies have been published concerning the potential ecotoxicological risks of
titanium dioxide nanoparticles (nano-TiO 2), but the results still remain inconclusive. The …

The production and use of nanoparticles (NPs), especially those of titanium dioxide (TiO2)
have increased steadily within the last decade. Common knowledge of photoactive …

Abstract Background, Aim and Scope Due to their large potential for manifold applications,
the use of nanoparticles is of increasing importance. As large amounts of nanoparticles may …

Highlights•UV exposure greatly increased ROS production in mixture of nano-TiO 2 and
algae.•Nano-TiO 2 inhibited algal growth under visible light.•UV pre-exposure did not …

Titanium dioxide nanoparticles are photoactive and produce reactive oxygen species under
natural sunlight. Reactive oxygen species can be detrimental to many organisms, causing …

Nanoparticulate titanium dioxide (TiO2) is highly photoactive, and its function as a
photocatalyst drives much of the application demand for TiO2. Because TiO2 generates …

Given the extensive use of nanomaterials, they may enter aquatic environments and harm
the growth of algae, which are primary producers in an aquatic ecosystem. Thus, the …
