Source assessment of atmospheric lead measured at Ny-Ålesund, Svalbard
Size-segregated (PM10) aerosol samples were collected at Ny-Ålesund (Svalbard Islands, Norwegian Arctic) from April to September 2012 and analysed for lead content and isotopic composition (207Pb/206Pb and 208Pb/206Pb), along with other chemical tracers, such as aluminium (crustal marker) and non-se...
