A sensitive determination of lead by hydride generation integrated with micro-sampling gas–liquid separator-FAAS after preconcentration by NiFe2O4 nanoparticles by Merve Fırat Ayyıldız, Süleyman Bodur, Sezgin Bakırdere

“…Abstract In the present study, dispersive solid phase extraction – hydride generation integrated with micro–sampling gas–liquid separator – flame atomic absorption spectrometry was proposed to determine lead in lake water samples taken in the Horseshoe Island, Antarctica. In scope of this study, microwave assisted NiFe2O4 nanoparticles were synthesized, and the characterization of nanoparticles were carried out by FT-IR, XRD and SEM. …”

The use of eDNA in the reconstruction of present and past polar vertebrates’ populations by Rodrigo Goldenberg-Barbosa, Anna Donato, Dafne Anjos, Cesar Amaral

“…In this article, we review the currently published research on vertebrate eDNA in the Arctic, as well as compare it with a similar already-published article on Antarctica. Our results show how the Artic region is well represented with several studies focusing on vertebrates, being the second most researched group of organisms (19%), only behind plants, and with several studies related to the development of new approaches and methodologies for the use of eDNA from cold regions being published in the last years. …”

Strong turbulent flow in the subauroral region in the Antarctic can deteriorate satellite-based navigation signals by D. S. Kotova, A. A. Sinevich, A. A. Chernyshov, D. V. Chugunin, Y. Jin, W. J. Miloch

“…We show that at the moment of auroral activity intensification, an increase in the magnitude of phase scintillation index (σϕ) as well as loss of satellite signals lock were observed in the region of the PJ/SAID equatorward of the auroral oval over Dronning Maud Land (Queen Maud Land) in Antarctica. We find that fluctuations inside the PJ/SAID can lead to serious deterioration of radio communication or navigational services. …”
