Cover Story: Suspended particulate matter plays a crucial role in the global climate system and can negatively disturb remote places, such as in the Antarctic region. Aerosol measurements were recorded using a low-volume sampler on Deception Island (Gabriel de Castilla Spanish base, South Shetlands Islands, Antarctic region). Inductively coupled plasma-mass spectrometry (ICP-MS) and inductively coupled plasma-atomic emission spectroscopy (ICP-AES) were used to chemically characterize Antarctic atmospheric aerosols. Then, air mass backward trajectory models, together with polar contour maps and statistical tools, were implemented to better understand the potential remote and local sources of these atmospheric elements.
