Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

Environmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

Environmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.
