Arsenic and trace metal contents in sediment profiles from the Admiralty Bay, King George Island, Antarctica.
Admiralty Bay (Antarctica) hosts three scientific stations (Ferraz, Arctowski and Macchu Picchu), which require the use of fossil fuel as an energy source. Fossil fuels are also considered the main source of pollution in the area, representing important inputs of major pollutants (organic compounds) and trace metals and metalloids of environmental interest. Accordingly, this work presents the r...
متن کاملSediment geochemistry in coastal maritime Antarctica (Admiralty Bay, King George Island): Evidence from rare earths and other elements
We report the concentrations of 22 elements in short coastal sediment cores of Admiralty Bay (King George Island, Antarctica) determined by Neutron Activation Analysis. We focus the discussion on rare earth elements (REE) because their fractionation patterns in sediments relative to local sources may offer insights about weathering, transportation, deposition, and diagenetic processes. We found...
متن کاملFour-year survey of dissolved/dispersed petroleum hydrocarbons on surface waters of Admiralty Bay, King George Island, Antarctica
• Abstract: Seawater from 8 stations in Admiralty Bay was systematically sampled during the summer of 1994, 1995, 1996 and 1997 and analyzed by spectrofluorimetry to measure dissolved/dispersed petroleum hydrocarbons (DDPHs). The purpose of this study was to detect some temporal and spatial changes in terms of oil contamination of the region. The results indicate low levels of oil pollution wit...
متن کاملSpatial variability models of CO2 emissions from soils colonized by grass (Deschampsia antarctica) and moss (Sanionia uncinata) in Admiralty Bay, King George Island
Soil CO2 emission is an important part of the terrestrial carbon cycling and is influenced by several factors, such as type and distribution of vegetation. In this work we evaluated the spatial variability of soil CO2 emission in terrestrial ecosystems of maritime Antarctica, under two contrasting vegetation covers: 1) grass areas of Deschampsia antarctica Desv., and 2) moss carpets of Sanionia...
متن کاملArsenic, Copper and Zinc in Marine Sediments from the Proximity of the Brazilian Antarctic Base, Admiralty Bay, King George Island, Antartica
Marine sediments collected, in March/2010, close to the Comandante Ferraz Base, located in Admiralty Bay, Antarctica, were analyzed to determine arsenic (As), copper (Cu) and zinc (Zn) levels, in order to indicate the impact of the Brazilian activities in the study area. Labile concentrations of As ranged from 6 to 10 μg.kg–1, Cu and Zn content ranged from 80 to 91 and 50 to 57 μg.kg–1, respect...
