Are TiO₂ nanoparticles safe for photocatalysis in aqueous media?

Abstract

Herein TiO2 nanoparticles toxicological assessment under the application framework is shown, depicting the relation among photocatalysis, catalyst release, and the associated potential environmental hazards using zebrafish embryos.

Tutorial review on the processing and performance of fabrics with antipathogenic inorganic agents

“…When leached, titania nanoparticles can be released into aquatic environments and be harmful to organisms essential to the ecosystem. Valério et al ( 2020 ) investigated potential harms caused by TiO 2 nanoparticles using the embryonic development of zebrafish ( Danio rerio ) as a proxy. Acute sublethal effects were recorded in zebrafish embryos at different stages of development, related to the release of TiO 2 nanoparticles into the aquatic environment (Fig.…”

“…15 Structural defects, such as yolk deformations, pericardial edemas, arched tails, and others, can be observed in the developmental traits of zebrafish larvae induced by TiO 2 . Adapted from Valério et al ( 2020 ) …”

Polymer Nanocomposites Based on TiO2as a Reinforcing Agent: An Overview

“…[ 67 ] Recently, more research efforts have been focused on the fabrication of NC membranes based on TiO 2 for the treatment of wastewater that can be used several times. [ 68 ] In fact, TiO 2 imparts hydrophilicity and antifouling characteristics to the fabricated membranes resulting in enhancement of the water flux, removal of excess salts, and their reuse capability. [ 69 ] In addition, the photocatalytic property of TiO 2 is being exploited for the degradation of dyes/organic effluents from industrial wastewater.…”

The upsurge of photocatalysts in antibiotic micropollutants treatment: Materials design, recovery, toxicity and bioanalysis

“…The recent review article by Friehas et al (156) and other reports (179)(180)(181)(182) narrates the toxicity and phototoxicity of nanoscale photocatalysts. Detailed in-vitro and in vivo studies have demonstrated on toxicity effect of nanoparticles by several researchers in different applications, including water treatment (183)(184)(185). Phytosynthesis (plants extract) based green synthesized photocatalyst materials having bio-friendly green organic chemicals (chlorophyll, polyphenols, etc.)…”
