Ecotoxicological Effects of TiO₂ P25 Nanoparticles Aqueous Suspensions on Zebrafish (Danio rerio) Eleutheroembryos.

ABSTRACT: Among nanoparticles (NPs), titanium dioxide is one of the most highly manufactured worldwide and widely used in multiple products for both industrial use and personal care products. This increases the probability of release into aquatic environments, potentially affecting these ecosystems. The present study aimed to evaluate TiO₂ P25 NP toxicity in zebrafish embryos and eleutheroembryos by evaluating LC₅₀, hatching rate, embryo development, and chemical analysis of the TiO₂ concentration accumulated in eleutheroembryo tissues. Zebrafish embryos ~2 h post-fertilization (hpf) were exposed to 75, 100, 150, 200, and 250 mg/L TiO₂ P25 NPs for 48 and 96 h. A total of 40-60 embryos were placed in each Petri dish for the respective treatments. Three repl
