Ed O’Loughlin is an environmental chemist/environmental microbiologist specializing in the biogeochemical processes controlling the cycling of major/minor elements and the fate and transport of contaminants in natural systems.
Ed’s research intersects several major disciplines, including environmental microbiology, environmental chemistry, and geology. He has been studying biogeochemical processes in aquatic and terrestrial systems for nearly 25 years, the last 12 of which have been with the Molecular Environmental Science Group in the Biosciences Division at Argonne.
Ed’s current research focuses on the effects of microbial transformations of carbon, iron, and sulfur on the fate and transport of uranium and mercury in subsurface environments. He is also focused on investigating microbial contributions to the release of methane, a potent greenhouse gas, from aquatic and terrestrial environments.
His previous research efforts have investigated the biotic (microbial) and abiotic (chemical) transformations of organic and inorganic contaminants, including chlorinated solvents (PCE, TCE, carbon tetrachloride, etc.), organotin biocides (tributyltin), aromatic N-heterocycles (pyridine, quinolone, etc.), heavy metals (mercury, copper, chromium), and radionuclides (uranium). Ed has also studied microbial processes controlling the biogeochemical cycling of carbon, sulfur and iron and has extensive experience in the characterization of natural organic matter, particularly humic and fulvic acids.
