Grantee Research Project Results

Research Centers
Center for Airborne Organics (MIT)

Massachusetts Institute of Technology

The Center was established to address research on air pollution problems. Its focal areas include: sources and control, transport and transformation, and monitoring and source attribution. Specific research projects have made advances in factors governing the formation of soot and on the sources of VOC emissions from engines (sectional molecular model following the transition from gas phase to particle inception and growth); minimizing soot and nitric oxide emissions from diesel engines; kinetics of blends of oxygenates; photochemical processes forming organic aerosols; analyses of trace VOCs; mapping of temporal and spacial distribution of mutagenic activity in the LA basin; quantitative measures of the physical and chemical structures of soots. The center also coordinates symposia covering areas such as Effective Technologies for Reducing Vehicle Emissions; and air pollution instrumentation.
