Local Structures of Se and Br in Cretaceous–Paleogene Boundary Sediments and Concentration Effects of Ferrihydrite Originating From Impact Ejecta

open access: yesGeological Journal, EarlyView.
Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

Developmental and Behavioral Effects of Arsenobetaine in Zebrafish (Danio rerio)

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Arsenobetaine (AsB) is a prevalent organoarsenical in aquatic environments and is generally regarded as nontoxic. Despite its widespread occurrence, the developmental and neurobehavioral toxicity of AsB has not been systematically investigated.

Effects of arsenate on the growth and microcystin production of Microcystis aeruginosa isolated from Taiwan as influenced by extracellular phosphate

open access: yes, 2009
Arsenic pollution and eutrophication are both prominent issues in the aquaculture ponds of Taiwan. It is important to study the effects of arsenic on algal growth and toxin production in order to assess the ecological risk of arsenic pollution, or at ...

Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.

"Artifactual" arsenate DNA

open access: yes, 2012
The recent claim by Wolfe-Simon et al. that the Halomonas bacterial strain GFAJ-1 when grown in arsenate-containing medium with limiting phosphate is able to substitute phosphate with arsenate in biomolecules including nucleic acids and in particular DNA(

is a high‐affinity arsenate transporter [PDF]

open access: yes, 2016
© 2015 New Phytologist Trust. Pteris vittata exhibits enhanced arsenic uptake, but the corresponding mechanisms are not well known. The prevalent form of arsenic in most soils is arsenate, which is a phosphate analog and a substrate for Phosphate ...

Nanostructured Fe2O3/Al2O3 Adsorbent for removal of As (V) from water [PDF]

open access: yesAdvances in Environmental Technology, 2017
The presence of arsenate in drinking water causes adverse health effects including skin lesions, diabetes, cancer, damage to the nervous system, and cardiovascular diseases. Therefore, the removal of As (V) from water is necessary.

Arbuscular mycorrhizal fungi enhance plant performance in trace element‐contaminated soils with element‐specific accumulation patterns

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Soil contamination by toxic trace elements is a growing global challenge that threatens food safety, agricultural productivity, and ecosystem health. We combined results from many experiments worldwide to assess whether beneficial soil fungi can help plants cope with contaminated soils.

Multi-Component Antioxidative System and Robust Carbohydrate Status, the Essence of Plant Arsenic Tolerance

open access: yesAntioxidants, 2020
Arsenic (As) contaminates the food chain and decreases agricultural production through impairing plants, particularly due to oxidative stress. To better understand the As tolerance mechanisms, two contrasting tobacco genotypes: As-sensitive Nicotiana ...
