Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

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.

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 ...

Sulfasalazine Enhances Copper Toxicity in Danio rerio Larvae: Divergent Protective Roles of Deferoxamine and Ferrostatin‐1

Environmental Toxicology, EarlyView.
ABSTRACT Copper is an environmental contaminant capable of disrupting redox homeostasis and impairing antioxidant defenses in aquatic organisms, thereby increasing susceptibility to oxidative stress. The cystine/glutamate antiporter (system xc−) plays a central role in maintaining intracellular glutathione (GSH) levels, a major antioxidant defense ...
