Combination of flow injection analysis with flame atomic-absorption spectrophotometry: determination of trace amounts of heavy metals in polluted seawater

Svend Olsen, +3 more
- 01 Jan 1983 - 
TL;DR: A simple flow injection system, the FIAstar unit, was used to inject samples of seawater into a flame atomic-absorption instrument allowing the determination of cadmium, lead, copper and zinc at the parts per million level at a rate of 180-250 samples per hour as mentioned in this paper.
Journal ArticleDOI

Paleo-environmental change in Amazonian and African rainforest during the LGM

Dieter Anhuf, +13 more
- 25 Sep 2006 - 
TL;DR: In this article, the tropical South American LGM data were interpreted from pollen, geochemical, and δ18O (stable oxygen isotope) data from Brazil and selected surrounding areas and the available terrestrial data were consistent with the SST derived precipitation data for the tropical forests in Brazil and for Africa.
Journal ArticleDOI

Radiocarbon dating of total soil organic matter and humin fraction and its comparison with 14C ages of fossil charcoal

Luiz Carlos Ruiz Pessenda, +2 more
- 01 Jan 2001 - 
TL;DR: In this article, the (super 14) C dating of soil organic matter (SOM), humin fraction, and charcoal in several soil profiles under natural vegetation from different Brazil locations (north, central, and southeast regions).
Journal ArticleDOI

Late Quaternary Vegetation Dynamics in the Southern Amazon Basin Inferred from Carbon Isotopes in Soil Organic Matter

H. A. Freitas, +5 more
- 01 Jan 2001 - 
TL;DR: Carbon isotopes of soil organic matter (SOM) were used to evaluate and establish the chronology of the vegetation dynamics of an ecosystem presently composed of savannas surrounded by forests as discussed by the authors.
Journal ArticleDOI

Relative sea-level changes in the last 5500 years in southern Brazil (Laguna–Imbituba region, Santa Catarina State) based on vermetid ages

Rodolfo José Angulo, +3 more
- 01 Jul 1999 - 
TL;DR: In this article, radiocarbon dates from vermetid shells collected in the southernmost sector of the Brazilian rocky coast presented dates ranging from 5410±80 to 190±65 years B.P., with associated paleosea levels varying from +2.10 m to +0.20 m above present sea level.
