Return to baseline arsenic concentrations after 1 year on gluten‐free diet in children with celiac disease: A prospective cohort study

open access: yesJPGN Reports, EarlyView.
Abstract Objectives Lifelong adherence to a gluten‐free diet (GFD) is the primary treatment for celiac disease (CeD). Concerns have been raised about increased exposure to contaminants in a GFD because rice, which naturally bioaccumulates arsenic and other environmental contaminants, is commonly used as a substitute for gluten.

New age‐estimate data and implications for marine isotope stage 7 and 5e sea levels in Fenland, eastern England

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...

Joint and Rapid Determination of 210Pb-210Bi-210Po in Rock, Soil and Sediment Samples by Constant Temperature Spontaneous Deposition on Cu-foil with Gross α and Gross β Counting

open access: yesYankuang ceshi, 2013
Measurement techniques of uranium series nuclides 210Pb, 210Bi and 210Po are relatively independent at present for most cases, and there are still some technical issues that need to be overcome.

Integrating Aegean Last Interglacial faunas into the Mediterranean palaeobiogeographic framework: New evidence from Karpathos (Greece)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Last Interglacial (LIG) or Marine Isotope Stage (MIS) 5e, spanning 129 to 116 kyrs ago, is recognised as one of the warmest periods in the Quaternary, with global sea surface temperatures (SSTs) 1°C–2°C higher than today, sea levels 5–10 m above the current level and biogeographical range expansion of specific tropical species into the ...

Cyclic oxygen vacancy reconstruction in MnO2 polymorphs builds electron reservoirs to drive ionic charge redistribution for stepwise UO22 + reduction

open access: yesEcotoxicology and Environmental Safety
Effective uranium (UO22+) recovery from aqueous waste is vital for resource sustainability and environmental safety. Although oxygen vacancies enhance the redox activity of UO22+, their long–term stability and ability to regenerate remain unclear. Herein,

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry
