Article Synopsis
- * Researchers studied 78 Antarctic fish to check for microplastic contamination over time.
- * Results show more synthetic fibers now than in 1998, likely due to increased human activity, which stresses the need for better environmental care.

A new Continuous Flow Analysis (CFA) system coupled with Fast Liquid Chromatography - tandem Mass Spectrometry (FLC-MS/MS) has been recently developed for determining organic markers in ice cores. In this work we present an upgrade of this innovative technique, optimized for the detection of levoglucosan in ice cores, a crucial tracer for reconstructing past fires. The upgrade involved a specific optimization of the chromatographic and mass spectrometric parameters, allowing for a higher sampling resolution (down to 1 cm) and the simultaneous collection of discrete samples, for off-line analysis of water stable isotopes and additional chemical markers.

- Scientists found tiny particles, called anthropogenic microparticles (AMs), in fish from Antarctica that were collected in 1998.
- Most of these particles were fibers, both natural and made by humans, like polyester and polypropylene, which are used in clothes and other items.
- The study shows that pollution from microplastics had already started affecting the Antarctic ocean environment long before we often think it began, helping us understand how pollution has changed over time.
The Great Acceleration of fragrances and PAHs archived in an ice core from Elbrus, Caucasus.

The Great Acceleration of the anthropogenic impact on the Earth system is marked by the ubiquitous distribution of anthropogenic materials throughout the global environment, including technofossils, radionuclides and the exponential increases of methane and carbon dioxide concentrations. However, personal care products as direct tracers of human domestic habits are often overlooked. Here, we present the first research combining fragrances, as novel personal care products, and polycyclic aromatic hydrocarbons (PAHs) as combustion and industrial markers, across the onset of the Great Acceleration in the Elbrus, Caucasus, ice core.
