Simple Generation of Suspensible Secondary Microplastic Reference Particles via Ultrasound Treatment

Frontiers in Chemistry, 2020
In the environment the weathering of plastic debris is one of the main sources of secondary microplastic (MP). It is distinct from primary MP, as it is not intentionally engineered, and presents a highly heterogeneous analyte composed of plastic ...

New Experimental Tools to Use Noble Gases as Artificial Tracers for Groundwater Flow

Frontiers in Water, 2022
Labeling groundwater by injecting an artificial tracer is a standard and widely used method to study groundwater flow systems. Noble gases dissolved in groundwater are potentially ideal artificial tracers, as they are not subject to biogeochemical ...

Groundwater ages, recharge conditions and hydrochemical evolution of a barrier island freshwater lens (Spiekeroog, Northern Germany) [PDF]

, 2012
Freshwater lenses below barrier islands are dynamic systems affected by changes in morphodynamic patterns, groundwater recharge and discharge. They are also vulnerable to pollution and overabstraction of groundwater.
