The toxicity of tris (2-butoxyethyl) phosphate (TBOEP) has been extensively investigated because of its prevalence in the environment. Nevertheless, the risk factors associated with maternal transmission are poorly understood. In this study, sexually mature female zebrafish were treated with TBOEP (0, 20, 100, and 500 μg/L) for 30 days and were mated with unexposed males.

Monitoring selenium (Se) concentrations in fish ovaries is an important tool for evaluating the ecological risk posed by Se in aquatic systems. Most guidance recommends sampling fish ovaries as closely as possible to when fish spawn on the premise that Se is mobilized from the liver to the ovary during vitellogenesis, and therefore, sampling ovaries during the early phases of oocyte maturation may underestimate egg Se concentrations at the time of spawning. In this study, we evaluated ovary Se data from two species with synchronous oocyte development (Ptychocheilus oregonensis and Prosopium williamsoni), one species with asynchronous oocyte development (Richardsonius balteatus), and one where the mode of development is unclear (Mylocheilus caurinus).

Perfluorooctanoic acid (PFOA) and nano-titanium dioxide (nano-TiO₂) are widely used in industrial applications such as manufacturing and textiles, and can be released into the environment, causing toxicity to marine organisms. To study the effects of these pollutants on the gonadal development, we exposed the males of Mytilus coruscus to varying PFOA concentrations (2 and 200 μg/L) alone or combined with nano-TiO (0.1 mg/L, size: 25 nm) for 14 days.

As global change threatens avian biodiversity, understanding species responses to environmental perturbations due to radiation emitted by enormous increase in the application of wireless communication is very urgent. The study investigates the effect of MW radiation on redox balance, stress level, male fertility and the efficacy of Withania somnifera (WS) root extract (100 mg/kg body weight) orally administered in 8 weeks old mature male Japanese quail exposed to 2.4 GHz MW radiation for 2 h/day for 30 days with power density = 0.

Per and polyfluoroalkyl substances (PFAS) are anthropogenic chemicals extensively used in consumer products. Perfluorobutane sulfonate (PFBS), a short-chain PFAS, has been introduced as an alternative to long-chain PFAS, but limited studies have investigated its reproductive toxicity in fish. In this study, adult zebrafish were exposed to PFBS at concentrations of 0.
