ANALYSIS OF OXYGENATED POLYCYCLIC AROMATIC HYDROCARBONS AND THEIR PARENT MOLECULES IN BIOCHAR AND ITS LEACHATES
Phillips, Stephanie Caroline Webb (East Carolina University, 2017-12-13)Due to the increasing use of biochar as a soil amendment, the amount and composition of contaminants in biochar should be analyzed. Two of those suites of compounds in biochar are polycyclic aromatic hydrocarbons (PAHs) ... -
Atmospheric Distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in Coastal Northern Gulf of Mexico, USA, Associated with the Deepwater Horizon Oil Spill

Holocene Climate and Carbon Sequestration via Black Carbon Burial in Sediments
Patel, Nidhi (East Carolina University, 2011)Fire, a global process that depends on climate, volcanic activity, vegetation and human practices is not constant through time and varies at decadal, centennial and millennial time-scales. Wildfires that result in burning ... -
A Holocene record of climate-driven shifts in coastal carbon sequestration
Mitra, Siddhartha; Zimmerman, Andrew R.; Hunsinger, Glendon B.; Willard, Debra; Dunn, Joshua C. (2009)A sediment core collected in the mesohaline portion of Chesapeake Bay was found to contain periods of increased delivery of refractory black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs). The BC was most likely ... -
Impact of Hurricane Katrina (2005) on deltaic evolution and shelf organic carbon cycling
Allison, M.A.; Dellapenna, T.M.; Gordon, Elizabeth S.; Mitra, Siddhartha; Petsch, S.T. (2010)Sediment cores from the continental shelf adjacent to the Mississippi River delta immediately after the passage of Hurricane Katrina were used to examine the magnitude, and implications for the carbon budget, of sediment ... -
