Unprecedented radioactive pollution in Spitsbergen's air – first data of the 21st century

open access: yesAtmospheric Chemistry and Physics
Abstract. This study investigated the Arctic troposphere, providing a comprehensive experimental database on nuclear aerosols that has significantly improved since 1999. The activity concentrations of 238Pu, 239+240Pu, and 241Am were measured in surface air at Hornsund, Spitsbergen, from 2007–2021.

Computational fluid dynamics numerical simulation of the effect of cooling towers on the diffusion of airborne radionuclides

open access: yesFushe yanjiu yu fushe gongyi xuebao
During the normal operation of cooling towers in nuclear power plants, water vapor with a certain temperature is discharged through the outlet of the cooling tower, which mixes with the surrounding air. A portion of this vapor condenses and forms visible

Recent Advances in the Preparation, Structural Modulation, and Applications of Metal–Organic Framework (MOF) Membrane Materials in the Field of Separation

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Metal–organic framework (MOF) membranes are a novel class of composite membranes. They use crystalline porous MOF materials as separation layers or functional fillers. Because of their well‐ordered and tunable pore structures and highly controllable chemical environments, MOF membranes show broad application prospects in gas separation ...

Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),

Unprecedented radioactive pollution in Spitsbergen air – first data as of 21st century

open access: yes
Abstract. The present study concerned the Arctic troposphere, providing an experimental database on nuclear aerosols that has improved considerably since 1999. The activity concentrations of 238Pu, 239+240Pu and 241Am were determined in the surface air of Hornsund, Spitsbergen, during 2007–2021.

Satire and Silence under Authoritarian Rule: Cotton and Pesticide Perceptions in Tajikistan

open access: yesJournal of Agrarian Change, Volume 26, Issue 4, October 2026.
ABSTRACT Over the past 70 years, agricultural chemicals have become a mainstay of cotton farming in Central Asia. This growing reliance on agrochemicals has not remained uncontested. This article analyses the politics of pesticides in Soviet and post‐Soviet Tajikistan by examining how, and to what extent, pesticides have featured in graphic satire, an ...

The Use of Radioactive Aerosols in the Ventilation Study of Persons Exposed to Air Pollution from the Oil Well Fires in Kuwait

open access: yesMedical Principles and Practice, 2008
The permeability of alveolar-capillary membrane of persons exposed to smoke from oil well fires in Kuwait is studied using a nuclear medicine imaging technique. This involves inhalation of radioactive aerosols generated from technetium-99m diethylenetriamine pentacetate (99mTc DTPA). A total of 100 subjects were divided into four groups.
