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.

SIÇAN TİROİD BEZİNDE KADMİYUM HASARINA KARŞI C VİTAMİNİ, E VİTAMİNİ VE SELENYUMUN KOMBİNE KULLANIMININ ETKİLERİ

Cerrahpaşa Medical Journal, 2014
Background and Design.- Histopathological alterations to various organs of the different species in acute and chronic cadmium exposure have been studied by light and electron microscopy. Metallothionein is a protein inducible by heavy metal ions. The aim

Protective Effects of Bee Venom (Apis mellifera) Against Cadmium‐Induced Hepatorenal Toxicity, Oxidative Stress, and Anxiety‐Like Behavior in Rats

Environmental Toxicology, EarlyView.
ABSTRACT Cadmium (Cd) is a persistent environmental heavy metal and a major public health concern because it persists in the body for long periods and gradually accumulates in vital organs, particularly the liver, kidneys, and brain. Chronic Cd exposure promotes the excessive production of reactive oxygen species (ROS), which ultimately leads to ...

Effect of Glutathione S‐Transferase and Metallothionein Polymorphisms on Mercury Levels and End‐Stage Renal Disease (ESRD) in Colombian Patients

Environmental Toxicology, EarlyView.
ABSTRACT Epidemiological studies have demonstrated a link between chronic kidney disease (CKD) and environmental mercury (Hg) exposure. Colombia has a well‐documented history of artisanal and small‐scale gold mining, where Hg exposure affects miners and nearby riverside and urban populations. This study aimed to evaluate the effects of polymorphisms in

Multiscale Effects of Environmentally Relevant Mixtures Containing Two Estrogenic Endocrine Disruptors, Chlordecone and Propylparaben, in Hydra vulgaris Pallas, 1766

Environmental Toxicology, EarlyView.
ABSTRACT This study investigates the chronic effects of chlordecone (CLD) and propylparaben (PP), two pro‐estrogenic endocrine disruptors, on Hydra vulgaris Pallas, 1766 using a multiscale approach over a 14‐day exposure period. Environmentally relevant concentrations of CLD (0.5, 5, 20 μg L−1) and PP (0.01, 0.05, 0.40 μg L−1) were tested individually ...
