UV filter benzophenone-2: Effects on zebrafish (Danio rerio) cytochrome P450.

Benzophenone-2 (2,2', 4,4'- Tetrahydroxybenzophenone; BP-2) is widely used as a sunscreen in Personal and Care Products (PCPs) for protection against ultraviolet (UV) radiation. The effects of BP-2 on random-sex adult zebrafish (Danio rerio) cytochrome P450 (CYP450) were studied. The main goal was to investigate the detoxification mechanisms underlying the adverse consequences of exposure to xenobiotic chemicals such as BP-2.

Toxicity of UV Filter Benzophenone-3 in Brine Shrimp Nauplii () and Zebrafish () Embryos.

The benzophenone (BP) family, including oxybenzone (BP-3), a prevalent sunscreen ingredient and environmental contaminant, has raised concerns since the year 2005. This study investigated oxybenzone toxicity in zebrafish () eleutheroembryos and brine shrimp () nauplii, focusing on the LC and developmental impacts. Zebrafish embryos (0.

Ecotoxicological Effects of TiO P25 Nanoparticles Aqueous Suspensions on Zebrafish () Eleutheroembryos.

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 TiO P25 NP toxicity in zebrafish embryos and eleutheroembryos by evaluating LC, hatching rate, embryo development, and chemical analysis of the TiO concentration accumulated in eleutheroembryo tissues.

Synthesis, Characterization, and Ecotoxicology Assessment of Zinc Oxide Nanoparticles by In Vivo Models.

The widespread use of zinc oxide nanoparticles (ZnO NPs) in multiple applications has increased the importance of safety considerations. ZnO NPs were synthesized, characterized, and evaluated for toxicity in and zebrafish (). NPs were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible (UV-Vis) spectroscopy.
