Dear list members,
this e-mail is to inform you about a
CALLL FOR PAPERS
for a symposium on
BLACK CARBON IN THE ENVIRONMENT: COMBUSTION RESIDUES - SOURCES AND FATES, CHARACTERIZATION AND BIOGEOCHEMCAL IMPLICATIONS
This symposium will address the natural sources, pathways and fates of black carbon, a heterogeneous continuum of combustion products (such as chars and soots) that are produced by combustion on the continents. Interest in black carbon has grown widely in the last several years based on the recognition that, in addition to having important influences on climate and health, soots and chars constitute major carbon forms in soils and sediments. This topic bridges the environmental (fossil fuel burning) and Earth (the global cycles of carbon and oxygen) sciences, as well as continental, atmospheric and aquatic geochemistry.
Please feel free to forward this information to interested colleagues.
Thank you and best wishes also on behalf of my co-chairs
Michael

CALL FOR PAPERS
Black Carbon in the Environment:
Combustion Residues - Sources and Fates, Characterization and Biogeochemical Implications
Symposium during the
9th Goldschmidt Conference
August 22-27 1999, Cambridge MA, USA
Black carbon, produced by incomplete combustion of fossil fuels and vegetation fires, is relatively resistant to degradation and occurs ubiquitously in natural environments, including soils, sediments, seawater and the atmosphere. In recent years, geochemical and biological studies of different forms of black carbon (such as plant chars, charcoals, and soots) received increasing attention due to potential importances in a wide range of biogeochemical processes. For example, black carbon may represent a significant sink in the global carbon cycle, affect earth˘s radiative heat balance, be a useful tracer for earthıs fire history, be a significant fraction of carbon buried in soils and sediments, and be an important carrier of organic pollutants.
Black carbon is presently being studied in a variety of widely separated scientific fields, with the result that essentially no generally accepted analytical protocols, terminologies and conceptual approaches exist. The aim of the symposium is to bring together a broad collegium of scientists ranging from geochemists to biologists and paleoenvironmentalists, to discuss the biogeochemical roles of black carbon in natural environments. In addition to stimulating interdisciplinary approaches, an additional goal of this symposium will be to encourage establishment of a collection of black carbon reference materials and to facilitate their comparative analysis by a range of commonly used techniques.
This emerging field of biogeochemical research will be addressed in two days of oral and poster presentations, including a special session dedicated to discussing potential comparison exercises. This symposium should attract a large number of participants from a broad and diverse background in carbon biogeochemistry, certainly including soil, sediment, and marine geochemists and biologists.
