LSU Chemistry mourns the passing of Harold Barry Dellinger, Professor Emeritus. Barry
received his BS from the University of North Carolina, Chapel Hill, in 1971 and his
PhD from Florida State University with Professor Kasha in 1975. From 1971-1981, he
served his country in the US Air Force and retired at the rank of Captain. He performed
postdoctoral studies with the late Professor Robin Hochstrasser at the University
of Pennsylvania. He spent 16 years at the University of Dayton Research Institute.
Dr Dellinger was recruited to LSU and appointed as Professor of Chemistry and Patrick
F. Taylor Chair in 1998. In the past 18 years, he has published more than 225 papers,
brought extensive research funding into LSU, graduated 12 PhD students and advised
several postdoctoral researchers and research associates. His research has focused
on thermal degradation kinetics and degradation profiles of organic compounds with
a special focus on the hazardous organic pollutants. These studies included evaluation
of principal organic hazardous pollutants for their destruction and removal efficiency
in both pyrolytic and oxidative conditions. His work led to the development of T99 theory or temperature of 99% destruction of chemicals at a specific residence time
and formed the foundation for what is used by the EPA to form their incinerability
ranking (a guide in the performance tests of incinerator systems). His work has significantly
contributed to the understanding of the factors determining the formation of polychlorinated
dibenzo-p-dioxins and polychlorinated furans (PCDD/F) in thermal processes. He was
the first scientist to propose the integrated model of PCDD/F formation including
all 3 pathways of formation (gas phase, surface precursor and de novo). In the last
15 years, his research has increasingly focused on the origin, fate, and health impacts
of particle-associated, environmentally persistent free radicals (EPFRs) and combustion
generated nanoparticles. His work has always been recognized by industry, policy-makers,
the research community and environmental groups.
Research funding has included support from NSF, EPA, tobacco companies, and more recently
and substantially, Dr Dellinger was the Director of the LSU Superfund Research Center
that received $15,291,598 (2011-16) to investigate the environmental and health impacts
of airborne pollutant-particle systems (environmentally persistent free radicals)
emitted from thermal remediation technologies or wind-blown dusts created during remediation
and containment activities of Superfund wastes. He has received numerous awards for
his contributions to science; a few of which are outlined here:
ACS Award for Creative Advances in Environmental Science and Technology (2014) for
creativity in research and technology or methods of analysis to provide a scientific
basis for informed environmental control decision-making processes, or to provide
practical technologies that will reduce health risk factors.
Elected as Fellow to the Association for the Advancement of Science (AAAS) (2010).
This was awarded based on is contributions to science and technology.
Astellas USA Foundation Award (2008) for having significantly contributed to scientific
research that improved public health through his and his laboratory’s contributions
in the chemical and related sciences.
After a long illness, Barry passed away in the early evening of March 9th, 2016.
