  1. Reconstructing the Record of Anthropogenic Pyrogenic Carbon Emissions Since the Onset of the Industrial Revolution: Location, Location, Location Louchouarn P1, Kopp K1, KjærK.K.2, IlsoeP2, Andresen C2, ChillrudS3& RumpelC4 1 Department of Marine Science, Texas A&M University at Galveston, USA. 2 Department of Geosciences and Natural Resource Management, University of Copenhagen, Denmark. 3 Department of Earth and Environmental Sciences, Columbia University, USA. 4LaboratoireBiogéochimie et écologie des milieuxcontinentaux, Site du Centre INRA Versailles-Grignon, France.

  2. Why Study Pyrogenic Carbon? Radiatively important aerosols (direct and indirect impacts) “Short-circuit” in the carbon cycle? • Atmospheric chemistry and health impact (PM2.5-10, PAHs, BC, VOCs) • Prescribed fires and wildfires contribute20% of the PM2.5 emissions in the U.S. Cooney, C. (2008) ES&T. Vol. 42( 5).

Vol. 92 Chemically heterogeneous, biologically refractory (?) class of carbon compounds produced during biomass burning and fossil fuel combustion Charcoal: Remains of solid fuel phase (retain structural character) Soot: Condensation of hydrocarbon radicals from gas phase into submicron particles (usually nucleated)

  5. PyC: Structural properties and molecular tracers • PAHs • Molecular carcinogenic contaminants • Emitted from incomplete combustion of organic matter. • Can be both pyrogenic as well as petrogenic. • Atmospheric increases primarily associated with the rise of industrial activities.

  7. Historical reconstruction of combustion:Working with historical archives Aquatic systems (and sedimentary systems) can be studied both in terms of their watershed and their airshed DeLuca and Aplet (2008) FEE. Vol. 6(1), 18-24 Lake Malawi - NASA: Visible Earth

  8. Methods • Sample Collection and analyses • Sediment Cores (urban lakes, urban coasts) • Dating methods • 210Pb and 137Cs • Pollens, biomarkers, historical events • Pyrogenic Carbon (PyC) • Two commonly used methods: CTO and GBC • PAHs (36 compounds) and diagnostic ratios

  9. Historical Air Quality:A Case Study I Black rain over NYC

  11. Sources of Soot-BC • d13C signatures of soot-BC • Homogeneity of inputs • Coal signatures with shift towards petroleum inputs in late 20th Century • Regional signatures (NYC vs Baltimore-DC)

  20. Conclusions • Local nature of fuel sources and consumption leads to geographical heterogeneities in PyC emissions and distribution  need for increased resolution of historical reconstructions. • A combination of elemental, isotopic, and molecular signatures of PyCin environmental archives show a strong potential for identifying fuel sources and regional distribution of combustion emissions from anthropogenic activities. • Urban lakes provides a unique opportunity for monitoring trends in markers of combustion over time in major urban system, but… Are they the best archives for climate reconstructions?
