  Nanoparticles (Np), as single particles with diameters smaller than 100 nm, represent a subgroup of nanomaterials. Their production and consumption have exponentially increased in recent years since they are used in the consumer products by different industrial sectors, for example, agriculture, construction, cosmetic, food and medicine. Nevertheless, researches on contamination caused by nanoproducts in aquatic environments are still scarce. Titanium dioxide (TiO2) has been used in various cosmetic applications due its ability to absorb UV light. Np-TiO2 in sunscreens has the same composition as the larger white TiO2 particles, but in nanoscale TiO2 is transparent, being more cosmetically elegant. The aim of this work was to evaluate the effect of TiO2 nanoparticles (TiO2- Np) on microalgae Chattonella subsalsa.. View More»
