Environmentally Realistic Metal Mixture Concentration Impacts Early Development in Zebrafish Larvae

Environmental Toxicology, EarlyView.
ABSTRACT The dispersion of metals in the environment leads to the presence of metal mixtures in impacted ecosystems, but few studies have addressed their impact on early developmental processes in fish. Here, we investigated the effect of metal mixtures reported in the Doce River basin in Brazil, including Fe, Mn, and Cd, either singly or as a mixture ...

PFOA Exposure Elicits Quantitative Lipidomic Changes in the Pancreas in a Mouse Model of Pancreatic Cancer

Environmental Toxicology, EarlyView.
ABSTRACT Pancreatic cancer is the fourth leading cause of cancer deaths in the US and predicted to rise to second by 2030. Several risk factors have been identified as potential contributors to pancreatic cancer development including lifestyle factors and long‐term exposure to occupational and environmental carcinogens.

Synergistic Toxicity of Low‐Concentration Metal Mixture on Male Rats: Reproductive, Renal, and Hepatic Effects

Environmental Toxicology, EarlyView.
ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

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.

Maternal Lead Exposure Induces Glandular Alterations in the Salivary Glands of Rat Male Offspring

Environmental Toxicology, EarlyView.
ABSTRACT Lead (Pb) is a widely distributed environmental pollutant that is highly noxious due to its toxicokinetic characteristics. Pb exposure can damage vital organ systems, including the central nervous and stomatognathic systems. As salivary glands play an important role in oral homeostasis, this study aimed to investigate the effects of maternal ...
