“…In Antarctica, it has already been observed that contamination can derive from both local sources and long-range transport. Previous studies highlighted the presence of metals, namely, Cd, Cr, Cu, Pb, and Zn, in particulate matter [7,36] and microplastics [37] related to the activities of the research stations in Antarctica, with wastewater, heating systems, and outdoor clothing or equipment being the major sources of contamination [7,37,38]. However, additional inputs derive from long-range transport.…”

The impact of the anthropic activities in Antarctica is a concerning issue. According to the Scientific Committee on Antarctic Research, attention has to be paid to the next-generation contaminants deriving from both long-range atmospheric transport and local sources. In this study, the capabilities of transmission electron microscopy with energy-dispersive X-ray spectroscopy and Raman micro-spectroscopy were exploited to evaluate the size, morphology, and chemical composition of small micro- and nanoparticles, as well as their aggregates, in surface snow samples collected during the 2020–2021 austral summer in the coastal area of Victoria Land near the Mario Zucchelli research station. The presence of biological particles, mineral dust, sea salts, and small carbonaceous and plastic micro- and nanoparticles was assessed. Sulfate, carbonate, and nitrate minerals were detected in all the samples, whereas polyethylene, poly(ethylene-co-vinyl-acetate), and different kinds of carbonaceous materials were predominantly identified in the samples closest to the research base. The presence of small micro- and nanoparticles containing heavy metals and plastic polymers in samples collected in the areas surrounding the Italian research base highlights the impact of anthropogenic activities on the polar environment, suggesting the need for continuous monitoring to evaluate possible threats to the delicate Antarctic ecosystem.

“…Their adverse effects result in changes in sex, developmental problems, cardiovascular disorders, hepatotoxicity, diabetes, and sexual dysfunction to name a few in both lower and higher animals [2,3]. Their widespread presence in trace amounts across different complex sample matrices has been reported in the literature [4][5][6]. Human exposure to these compounds primarily comes through ingestion of food and water [7].…”

Here, we deployed sol‐gel universal sorbent‐coated fabric phase sorptive extraction membranes in tandem with high‐performance liquid chromatography equipped with an ultraviolet detector (HPLC‐UV) for the analysis of 10 endocrine‐disrupting chemicals (EDCs). Due to the varying polarities of the studied compounds indicated by their octanol/water partition coefficient ‘log Kow’ (1.47–5.07), the extraction membrane was designed with different functionalities that are capable of simultaneous interaction with compounds of diverse natures including polar, non‐polar, and ionic species via sol‐gel sorbent coating technology. An isocratic mode of HPLC‐UV at 55:45% acetonitrile:water (v/v) on a reverse phase C18 Zorbax column (5 μm, 150 mm, 4.6 mm) was used for the separation and quantitation. Calibration curves were found linear between 25 and 2000 ppb for all compounds except cortisone in the range of 25–1000 ppb which provided an R2 value above 0.9940 in all cases. The intra‐day reproducibility and inter‐day reproducibility were found in the range of 1.2–12.8 and 0.2–14.1 (expressed as percent relative standard deviation), respectively. The validated method was finally deployed for the analysis of environmental water and milk samples with estradiol showing the highest concentrations among the studied compounds.
