metadata.value: Enormous deglaciation in the polar and mountainous regions of the Earth is associated
  not only with large-scale climatic changes but also with the global transfer of black carbon (BC)
  microparticles, which accumulate on the surface of glaciers and lead to changes in albedo and the rate
  of degradation of ice. BC is the product of an incomplete combustion of fossil fuels, volcanic eruptions,
  and wildfires. The accumulation of organogenic microparticles leads to the formation of cryoconites,
  which are dust made of a combination of small rock particles and the result of anthropogenic activities
  (fossil fuel combustion) that play a special role in deglaciation. Here, we describe the content of trace
  metals and nutrients in accumulation of the BC from glaciers of Fildes Peninsula, King George Island,
  Western Antarctica. The analysis of trace metals concentrations showed that most of the studied
  elements (Cr, Pb, Zn, Ni) have a volcanic origin; at the same time, Cd and Cu have been accumulated
  as a result of anthropogenic activity. The content of nutrients in BC are most similar with Technosols,
  which forms near the scientific station at King George Island. The particles of BC can be translocated
  into organisms, which could pose a significant risk for living organisms and humans.
