Toxicological Impacts of TiO Nanoparticles on Growth, Photosynthesis Pigments, and Protein and Lipid Content of the Marine Microalga Tetraselmis Suecica.

Regarding the widespread use of titanium dioxide nanoparticles (TiONPs) in industry, many concerns have been raised about the risks of their potential release into aquatic ecosystems. Among the marine primary producers, Tetraselmis suecica is an ecologically important microalgae species used also as live feed in the shrimp culture industry. In the present study, the impacts of TiONPs on growth performance, photosynthetic pigments, lipid and protein content and its interaction with the cells of T.

Toxicity of TiO nanoparticles to the marine microalga Chaetoceros muelleri Lemmermann, 1898 under long-term exposure.

Titanium dioxide nanoparticles (TiONPs) have been extensively used in industry, raising many concerns about their release into the aquatic environments. In marine ecosystems, microalgae are major primary producers; among them, Chaetoceros muelleri is an important microalga in the aquaculture industry as live feed. The impacts of TiONPs on the growth, photosynthetic pigments, protein and lipid contents, and the interaction of TiONPs with the cell wall of C.

Cytotoxic impacts of CuO nanoparticles on the marine microalga Nannochloropsis oculata.

The toxic impacts of CuO nanoparticles (NPs) on the marine phytoplankton Nannochloropsis oculata were evaluated by measuring a number of biological parameters. Exposure to different concentrations of CuO-NPs (5-200 mg/L) significantly decreased the growth and content of chlorophyll a of N. oculata.
