Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

Environmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Ecotoxicological Assessment of Mercury in Fish From a Gold‐Mining‐Impacted Amazonian River: Biomonitoring and Human Health Risk

Environmental Toxicology, EarlyView.
ABSTRACT The Peixoto de Azevedo River, located in northern Mato Grosso, southern Brazilian Amazon, has a long history of artisanal and small‐scale gold mining (ASGM). This study evaluated total mercury (THg) concentrations in fish tissues to assess biomagnification and potential risks.

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 ...

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.
