“…Recently, researchers used TiO 2 nano-particles to understand the hatching events and the embryo toxicity by evaluating the relationship between hatching success rate and hours post exposure. It was observed that TiO2 nanoparticles can cause premature hatching in zebrafish embryos, dose dependently [42]. Ong et al [43] also presented a view insight of zebrafish hatching under the effect of nanoparticle.…”

Presently, nanotechnology is a multi-trillion dollar business sector that covers a wide range of industries, such as medicine, electronics and chemistry. In the current era, the commercial transition of nanotechnology from research level to industrial level is stimulating the world’s total economic growth. However, commercialization of nanoparticles might offer possible risks once they are liberated in the environment. In recent years, the use of zebrafish (Danio rerio) as an established animal model system for nanoparticle toxicity assay is growing exponentially. In the current in-depth review, we discuss the recent research approaches employing adult zebrafish and their embryos for nanoparticle toxicity assessment. Different types of parameters are being discussed here which are used to evaluate nanoparticle toxicity such as hatching achievement rate, developmental malformation of organs, damage in gill and skin, abnormal behavior (movement impairment), immunotoxicity, genotoxicity or gene expression, neurotoxicity, endocrine system disruption, reproduction toxicity and finally mortality. Furthermore, we have also highlighted the toxic effect of different nanoparticles such as silver nanoparticle, gold nanoparticle, and metal oxide nanoparticles (TiO2, Al2O3, CuO, NiO and ZnO). At the end, future directions of zebrafish model and relevant assays to study nanoparticle toxicity have also been argued.

“…This concentration range 1) includes the median lethal concentration (LC50) for 96-h acute fish toxicity and the median effect concentration in the fish embryo test for 73 chemicals (Lammer et al 2009), 2) includes the predicted realistic and high emission environmental concentrations for nano-nTiO 2 in water (0.0007 and 0.016 mg/ mL, respectively; Mueller and Nowack 2008), and 3) extends both below and above the concentration range of prior studies of zebrafish exposed to waterborne nTiO 2 (Clemente et al 2014;Wang et al 2014;Yan et al 2014).

“…The impact of nTiO 2 exposure on zebrafish hatching events has been investigated and reported as premature hatching (Kovri znych et al 2013;Ma and Diamond 2013;Fouqueray et al 2013;Samaee et al 2015) or delayed hatching (Yeo and Jo 2007;Xu et al 2012). There are also other studies (e.g., Clemente et al 2014;Wang et al 2014;Yan et al 2014;Jovanovi c et al 2015) in which viability parameters (e.g., hatching events and/or survivability) have been considered to characterize nTiO 2 -induced toxicity.…”

Although the effects of nano-sized titania (nTiO ) on hatching events (change in hatching time and total hatching) in zebrafish have been reported, additional consequences of nTiO exposure (i.e., the effects of nTiO -induced changes in hatching events and morphometric parameters on embryo-larvae development and survivability) have not been reported. To address this knowledge gap, embryos 4 h postfertilization were exposed to nTiO (0, 0.01, 10, and 1000 μg/mL) for 220 h. Hatching rate (58, 82, and 106 h postexposure [hpe]), survival rate (8 times from 34 to 202 hpe), and 21 morphometric characteristics (8 times from 34 to 202 hpe) were recorded. Total hatching (rate at 106 hpe) was significantly and positively correlated to survival rate, but there was no direct association between nTiO -induced change in hatching time (hatching rate at 58 and 82 hpe) and survival rate. At 58, 82, and 106 hpe, morphometric characteristics were significantly correlated to hatching rate, suggesting that the nTiO -induced change in hatching time can affect larval development. The morphometric characteristics that were associated with change in hatching time were also significantly correlated to survival rate, suggesting an indirect significant influence of the nTiO -induced change in hatching time on survivability. These results show a significant influence of nTiO -induced change in hatching events on zebrafish embryo-larvae development and survivability. They also show that morphometric maldevelopments can predict later-in-life consequences (survivability) of an embryonic exposure to nTiO . This suggests that zebrafish can be sensitive biological predictors of nTiO acute toxicity. Environ Toxicol Chem 2018;37:3063-3076. © 2018 SETAC.

Titanium dioxide (TiO2) dispersions were obtained by neutralising anatase nano‐titanium dioxide sols prepared by hydrolysing tetrabutyl titanate in acidic aqueous media. Pyrite was initially prepared via the microwave‐assisted method with a mixed solvent of ethylene glycol and small amounts of water, and was then used in sensitising micron‐sized titanium dioxide particles to obtain aramid fabrics with self‐cleaning properties. X‐ray diffraction demonstrated the crystalline structure of pyrite, and ultraviolet‐visible (UV‐vis) spectrum and energy‐dispersive X‐ray spectroscopy characterised the band gaps, surface status on fabrics and the distribution of the pyrite compound's titanium dioxide particles. The contact angle, UV protection factor (UPF) and photocatalytic degradation of methylene blue (MB) were used to evaluate the performance of treated aramid fabrics. Results show that pyrite‐sensitised titanium dioxide compounds obtained at pH 5 have smaller band gap energies and relatively poor wetting abilities, higher UPF values, and perform well in the photocatalytic degradation of MB. The pseudo‐first kinetic model was used to analyse elaborate sections of the curve for the degradation of MB.
