Neurotoxic effect of TiO2 nanoparticles in Atya lanipes shrimp larvae

With the rapid development of the nanotechnology industry, the world is being attentive to the environmental impacts of manufactured nanoparticles. The production of TiO2 nanoparticles by 2025 is expected that it will reach 2.5 million metric tons. The rapid production and use of TiO 2 nanoparticles result in the direct and indirect release into aquatic environments through bathing, industrial effluent, and engineering applications, causing an influence in the river health and lotic ecosystem function and services. These changes can also affect shrimp larval survival and recruitment. These organisms have high chance of encountering suspended particles of pollutants in their migrations. One species of freshwater shrimp is Atya lanipes, which is known to affect detrital processing and nutrient availability to the rest ecosystem food web. Is important to know how this emerging aquatic pollutant can affect Atya lanipes normal migrations. The objective of this study is to understand the toxic effects of TiO 2 nanoparticles in post hatching Atya lanipes larvae under different nanoparticles concentrations (0.1, 1, 10, 50, 100 mg/L). The bioassay will analyze survival, morphological development and locomotion behavior after 24h, 48h and 72h post exposition times.
