Implications of Maternal Toxicant Effects on Size‐Dependent Fisheries' Management: A Meta‐Analysis

Fish and Fisheries, Volume 27, Issue 4, Page 895-911, July 2026.
Larger, older fish transfer higher mercury and PCB concentrations to their eggs, significantly reducing offspring hatching success, survival and growth rates in contaminated aquatic ecosystems. These findings suggest that the reproductive benefits of big old fat fecund female fish may be compromised by maternal toxicant transfer in polluted waters ...

Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

Impaired cross-talk between the thioredoxin and glutathione systems is related to ASK-1 mediated apoptosis in neuronal cells exposed to mercury

Redox Biology, 2017
Mercury (Hg) compounds target both cysteine (Cys) and selenocysteine (Sec) residues in peptides and proteins. Thus, the components of the two major cellular antioxidant systems – glutathione (GSH) and thioredoxin (Trx) systems – are likely targets for ...

Assessment of developmental neurotoxicity induced by chemical mixtures using an adverse outcome pathway concept

Environmental Health, 2020
Background In light of the vulnerability of the developing brain, mixture risk assessment (MRA) for the evaluation of developmental neurotoxicity (DNT) should be implemented, since infants and children are co-exposed to more than one chemical at a time ...

The Integration of Fire Ecology and Freshwater Ecosystems in North America: Knowledge Gaps and Research Needs

Global Change Biology, Volume 32, Issue 6, June 2026.
Illustration of key knowledge gaps and pathways linking fire ecology and freshwater ecosystems. Climate change provides the overarching context, interacting with cumulative and cross‐scale effects to shape local freshwater conditions. Within this context, fire characteristics influence three primary pathways within freshwater ecosystems: species and ...

Statement on the findings presented in the Toxicological Profile for Mercury issued by the US ATSDR

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Food Safety Authority (EFSA) was requested by the European Commission to deliver a statement on the findings presented in the Toxicological Profile for Mercury issued by the US Agency for Toxic Substances and Disease Registry (ATSDR) in 2024. The statement was endorsed by the CONTAM Panel before approval by EFSA. Although some key

Cytotoxicity and genotoxicity of low doses of mercury chloride and methylmercury chloride on human lymphocytes in vitro

Brazilian Journal of Medical and Biological Research, 2005
Mercury is a xenobiotic metal that is a highly deleterious environmental pollutant. The biotransformation of mercury chloride (HgCl2) into methylmercury chloride (CH3HgCl) in aquatic environments is well-known and humans are exposed by consumption of ...

Assessment of water quality and emerging pollutants in two fish species from the mallorquin swamp in the Colombian Caribbean

Heliyon
The Mallorquín Swamp, an important ecosystem in Atlántico, Colombian Caribbean, underwent environmental monitoring at eight points during rainy, transition, and dry seasons. This was to assess water quality, seasonal variation, and the bioaccumulation of

Mercury and selenium relationship in a tropical estuarine fish

Frontiers in Marine Science, 2015
Aquatic systems have been considered as final sinks for persistent and bioaccumulative toxicants (PBTs), such as metals and organohalogen compounds. Among the trace elements, non-essential metals deserve special attention due to their toxicity.
