dc.description.abstract | Nanotoxicity data for amphibians are limited compared to other taxonomic groups. The present study assessed toxicity of titanium dioxide nanoparticles ( nanoTiO2, anatase form, particle size < 25 nm) on tadpoles of Duttaphrynus melanostictus after short term and chronic exposures. Exposure to nanoTiO2 (≤ 100 mg/L) for 96 h had no significant effect on survival but upon transfer to nanoTiO2 free water for another 21 days, survival of the tadpoles pre-exposed to nanoTiO2 was greatly reduced and their development was delayed. Chronic exposure to nanoTiO2 (0.1 to 10 mg/L) for 14 days had no significant effects on acetylcholinesterase activities but induced mortalities (up to 40%) and histological alterations in the intestine and liver tissues. The results indicate that release of nanoTiO2 to aquatic ecosystems could pose negative impacts to amphibian populations. | en_US |
