Abstract
Increased manufacture of TiO2nanoproducts has caused concern about the potential toxicity of these products to the environment and in public health. Identification and confirmation of the presence of TiO2nanoparticles derived from consumer products as opposed to industrial TiO2NPs warrant examination in exploring the significance of their release and resultant impacts on the environment. To this end, we examined the significance of the release of these particles and their toxic effect on themarine diatom algae Thalassiosira pseudonana. Our results indicate that nano-TiO2sunscreen and toothpaste exhibit more toxicity in comparison to industrial TiO2 and inhibited the growth of the marine diatom T. pseudonana. This inhibition was proportional to the exposure time and concentrations of nano-TiO2. Our findings indicate a significant effect, and therefore, further research is warranted in evaluation and assessment of the toxicity of modified nano-TiO2 derived from consumer products and their physicochemical properties.
