This study investigates plutonium (Pu) isotopes preserved in nebkhas--aeolian dunes formed by shrubs intercepting wind-blown sands to reconstruct environmental changes in the semi-arid Mu Us dune field, northern China. Analysis results of two nebkha profiles reveal that the Pu/Pu atom ratios consistently approximate 0.18, indicating a dominant source from global fallout, with no significant local contributions from the Lop Nor or Semipalatinsk nuclear tests or the Chernobyl accident.

Monitoring coastal dynamics is critical for the effective protection of coastal environments. Satellite remote sensing data offers significant potential to support this monitoring while also addressing the considerable challenges posed by the rapidly changing environmental conditions in coastal regions, such as tidal levels and currents. These challenges are particularly pronounced in meso- and macrotidal coastal areas.

Slow sand filters (SSFs) are commonly used for treating drinking water, effectively removing contaminants such as particles, organic matter, and microorganisms. However, the ecological dynamics of prokaryotic communities within SSFs remain poorly understood. This study investigated the top sand layer, the Schmutzdecke (SCM), along with the influent and effluent water of full-scale SSFs at four drinking water treatment plants (DWTPs) in the Netherlands.

infections severely impact patients who are immunocompromised. Currently, there are limited options to treat fungal infections, especially drug-resistant-fungal infections. Therefore, investigating alternative or repurposed antifungals is paramount.
