Thioredoxin 1 and Thioredoxin Reductase 1 Redox System Is Dysregulated in Neutrophils of Subjects with Autism: In Vitro Effects of Environmental Toxicant, Methylmercury

open access: yesToxics, 2023
Autism spectrum disorder (ASD) is a complex developmental disorder in children that results in abnormal communicative and verbal behaviors. Exposure to heavy metals plays a significant role in the pathogenesis or progression of ASD.

Glutathione reductase plays a role in the metabolism of methylmercury degradation in Rhodotorula mucilaginosa [PDF]

open access: yesMicrobiology Spectrum
Mercury pollution is a kind of heavy metal pollution with great harm and strong toxicity which exists worldwide. Some microorganisms can convert highly toxic methylmercury into inorganic mercury compounds with significantly reduced toxicity.

Molecular composition of organic matter controls methylmercury formation in boreal lakes

open access: yesNature Communications, 2017
Neurotoxic methylmercury can be found in high levels in aquatic systems, but the role of organic matter in methylmercury formation is not well understood. Here, Bravoet al.

Assessment of background concentrations of organometallic compounds (methylmercury, ethyllead and butyl- and phenyltin) in French aquatic environments [PDF]

open access: yesWater Research, 2016
The aim of this work is to estimate background concentrations of organometallic compounds, such as tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT), triphenyltin (TPhT), diphenyltin (DPhT), monophenyltin (MPhT), methylmercury (MeHg), inorganic mercury (iHg) and diethyllead (Et2Pb) in the aquatic environment at the French national scale.

Gaschromatographic determination of methylmercury compounds from samples containing sulfide

open access: yesBUNSEKI KAGAKU, 1970
硫化物を含む試料中のメチル水銀化合物をガスクロマトグラフィーで定量する場合,硫化物による妨害を防ぐため,塩化第二水銀を試料に添加する方法が従来用いられていた.しかし,本研究の結果,塩化第二水銀の一部は有機溶媒で抽出され,また塩化第二水銀がメチル塩化水銀と混在すると,得られたピークはメチル塩化水銀,塩化第二水銀それぞれ単独のピークの和よりも増大したので,塩化第二水銀の添加は適当でない.硫化物はメチル水銀化合物をビス-硫化ジメチル水銀に変化させ,グルタチオンあるいはシステイン処理では抽出できなかったので,塩化第一銅を試料に添加してビス-硫化ジメチル水銀を完全にメチル塩化水銀の形に変化させたのちに抽出,ガスクロマトグラフィーにより定量を行なったところ好結果を得た.塩化銀はビス ...

Conventional Chromatographic Techniques and Biosensors for Mercury Speciation in Seafood: A Systematic Review [PDF]

open access: yesFoods
Mercury (Hg) is of significant concern due to its toxicity, which strongly depends on its chemical forms, and organic mercury compounds, particularly methylmercury (MeHg), are considered the most toxic species.
