Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current

Biochemical characterization and mercury methylation capacity of Geobacter sulfurreducens biofilms grown in media containing iron hydroxide or fumarate

Biofilm, 2023
Geobacter species are common in iron-rich environments and can contribute to formation of methylmercury (MeHg), a neurotoxic compound with high bioaccumulation potential formed as a result of bacterial and archaeal physiological activity.

Dietary Selenomethionine Reduce Mercury Tissue Levels and Modulate Methylmercury Induced Proteomic and Transcriptomic Alterations in Hippocampi of Adolescent BALB/c Mice

International Journal of Molecular Sciences, 2022
Methylmercury (MeHg) is a well-known environmental contaminant, particularly harmful to the developing brain. The main human dietary exposure to MeHg occurs through seafood consumption. However, seafood also contains several nutrients, including selenium,

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

Sustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Associations of gestational and early-life exposure to toxic metals and fluoride with a diagnosis of food allergy or atopic eczema at 1 year of age

Environment International, 2023
Studies have indicated that early-life exposure to toxic metals and fluoride affects the immune system, but evidence regarding their role in allergic disease development is scarce.

Metabolomic Responses of Green Alga Chlamydomonas reinhardtii Exposed to Sublethal Concentrations of Inorganic and Methylmercury.

Environmental Science and Technology, 2021
Metabolomics characterizes low-molecular-weight molecules involved in different biochemical reactions and provides an integrated assessment of the physiological state of an organism. By using liquid chromatography-mass spectrometry targeted metabolomics,

A Role for Gene-Environment Interactions in Autism Spectrum Disorder Is Supported by Variants in Genes Regulating the Effects of Exposure to Xenobiotics

Frontiers in Neuroscience, 2022
Heritability estimates support the contribution of genetics and the environment to the etiology of Autism Spectrum Disorder (ASD), but a role for gene-environment interactions is insufficiently explored.
