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.
