Research Interests of Participating Faculty
Alam Hasson, Chemistry.
This laboratory investigates the physical and chemical processes
leading to the formation of smog in the lower atmosphere. A
combination of Fourier Transform Infra-Red spectroscopy, High
Performance Liquid Chromatography, and Gas Chromatography with Flame
Ionization Detection and Mass Spectrometric Detection are used to
study the photo-oxidation pathways of organic pollutants in a smog
chamber. Current work focuses on formation pathways of
hydroperoxides, which may contribute to the formation, growth, and
toxicity of fine particulate matter. This laboratory also carries
out field measurements to investigate pollutant concentrations in
ambient air. Current projects include the quantification of
hydroperoxides and quinones in aerosols, and the measurement of
volatile organic compounds released from dairies. Students at both
the undergraduate and graduate levels are involved in these research
projects. Collaborators in this work include Dr. Suzanne Paulson
(UCLA), Dr Geoff Tyndall and Dr. John Orlando (National Center for
Atmospheric Research), and Dr. Keith Kuwata (Macalester College).
