Article Synopsis
- Sex determination in zebrafish can be influenced by environmental factors, such as exposure to cadmium (Cd) and temperature, which can lead to shifts in population sex ratios.
- Research shows that exposure to Cd resulted in increased methylation of certain genes, leading to a trend towards feminization over generations, especially under heat stress conditions.
- The study highlights the role of epigenetic mechanisms, particularly DNA methylation, in shaping sex ratios and suggests that parental environments can affect offspring development and sex determination.*
A nanometric revolution is underway, promising technical innovations in a wide range of applications and leading to a potential boost in environmental discharges. The propensity of nanoparticles (NPs) to be transferred throughout trophic chains and to generate toxicity was mainly assessed in primary consumers, whereas a lack of knowledge for higher trophic levels persists. The present study focused on a predatory fish, the European eel (Anguilla anguilla) exposed to gold NPs (AuNPs; 10 nm, polyethylene glycol-coated) for 21 d at 3 concentration levels in food: 0 (NP0), 1 (NP1), and 10 (NP10) mg Au kg .
