“…Raisbeck et al, 1978). 10 Be records have now been produced from multiple polar ice core sites, in both Greenland (e.g., Dye 3, GRIP, GISP2, Renland (Beer et al, 1990(Beer et al, , 1991Yiou et al, 1997;Finkel and Nishiizumi, 1997;Aldahan et al, 1998;Heikkilä et al, 2008b)) and Antarctica (e.g., Dome Concordia, South Pole, Dome Fuji, Taylor Dome, Queen Maud Land, Dronning Maud Land and Law Dome (Raisbeck et al, 1990;Steig et al, 1996;Aldahan et al, 1998;Smith et al, 2000;Moraal et al, 2005;Pedro et al, 2006;Horiuchi et al, 2008;Pedro et al, 2009)). Particular care in sample preparation and measurement is required for samples from Law Dome, where 10 Be concentrations are the lowest of all of these sites.…”

“…The names of the records refer to the sample site ("DSS") followed by the (austral) summer during which sampling took place (e.g., "0506" refers to summer of 2005 to 2006). DSS0506-core was drilled using a 195 mm diameter thermal drill (see also Burn-Nunes et al, 2011), whilst DSS0809 and DSS0910-core were drilled using 79 mm diameter Polar Ice Core Office (PICO) hand augers. Three PICO cores were drilled alongside each other in order to obtain sufficient mass for 10 Be measurements.…”

Abstract. Three near-monthly resolution 10 Be records are presented from the Dome Summit South (DSS) ice core site, Law Dome, East Antarctica. The chemical preparation and Accelerator Mass Spectrometer (AMS) measurement of these records is described. The reproducibility of 10 Be records at DSS is assessed through intercomparison of the ice core data with data from two previously published and contemporaneous snow pits. We find generally good agreement between the five records, comparable to that observed between other trace chemical records from the site. This result allays concerns raised by a previous Antarctic study (Moraal et al., 2005) about poor reproducibility of ice core 10 Be records. A single composite series is constructed from the three ice cores providing a monthly-resolved record of 10 Be concentrations at DSS over the past decade (1999 to 2009). To our knowledge, this is the first published ice core data spanning the recent exceptional solar minimum of solar cycle 23. 10 Be concentrations are significantly correlated to the cosmic ray flux recorded by the McMurdo neutron monitor (r xy = 0.64, with 95 % CI of 0.53 to 0.71), suggesting that solar modulation of the atmospheric production rate may explain up to ∼40 % of the variance in 10 Be concentrations at DSS. Sharp concentration peaks occur in most years during the summer-to-autumn, possibly caused by stratospheric incursions. Our results underscore the presence of both production and meteorological signals in ice core 10 Be data.

“…Globally, many areas are impacted by the legacy of past metal mining and metal processing. A plethora of examples can be drawn from each of the continents: Mid-Welsh catchments, UK (Davies and Lewin, 1974;Lewin et al, 1977), the Matylda catchment, southern Poland (Ciszewski et al, 2012), Law Dome, Antarctica (Burn-Nunes et al, 2011), Guadalupe River and San Francisco Bay, California, USA (Thomas et al, 2002), the Pilcomayo catchment, Bolivia (Hudson Edwards et al, 2001), Endeavour Inlet, New Zealand (Wilson et al, 2004), Katanga, The Congo (Banza et al, 2009) and multiple locations in Japan (Arao et al, 2010).…”

The Derwent Valley Mills World Heritage Site (DVMWHS) exemplifies and records the 18 th century birth of the factory or mill technology, and for the industrial spinning of cotton. The site is therefore a key global heritage asset. The Derbyshire Derwent catchment also contains another significant cultural asset with a long history -that of mining and, in particular, lead (Pb) mining. In this paper research on mining-and non-mining related Pb contamination of the Derwent catchment is reviewed and used to identify the risks it poses to the DVMWHS.

ResumoAvaliar alterações nas concentrações de elementos-traço na neve da Antártica durante os últimos anos é de grande interesse para determinar em que medida as regiões mais remotas do nosso planeta estão sendo afetadas por emissões globais. Os elementos-traço estudados nesse trabalho foram determinados em um testemunho de firn da Antártica usando espectrometria de massas por plasma indutivamente acoplado. As concentrações obtidas para Al, As, Bi, Ca, Cd, Co, Cr, Fe, Li, Mg, Mn, Na, Pb, S, Sr e Ti são controladas pelas variações climáticas sazonais (verão/inverno), pela distância de transporte e pelas fontes naturais e antrópicas desses aerossóis. Contribuições naturais de solo, oriundas principalmente da região de Patriot Hills, são importantes fontes para alumínio, ferro, manganês e titânio. Os aerossóis marinhos, provenientes do gelo marinho e transportados pelas massas de ar, são fontes importantes de sódio, magnésio, estrôncio e enxofre. Lítio e cálcio apresentaram aportes consideráveis tanto de poeira continental como de aerossóis marinhos. Emissões vulcânicas foram consideradas fontes significativas de arsênio, bismuto, cádmio, cobalto, cromo e chumbo, com sua contribuição variando desde 10% (chumbo) até 85% (bismuto). Os fluxos de deposição natural de chumbo, cromo, bismuto e arsênio representaram apenas uma pequena fração do total depositado na neve. Para esses elementos, as atividades antrópicas ligadas à mineração e à queima de combustíveis fósseis no Hemisfério Sul possivelmente constituem o principal fator responsável por sua mobilização e transporte. Palavras-chave: elementos-traço, testemunho de firn, Antártica, ICP-MS.
