The environmental behavior of dimethoxy methane (DMM), a candidate oxygenate, was evaluated, as a step toward the development of more integrated fuel assessments. Although its volatility may present fuel-handling problems, DMM, produced from methanol, mixes well with diesel fuel. A chemical-kinetic combustion model was used to identify and compare the formation of air toxics. A regional-scale multicompartment model and soil/groundwater transport models were also utilized to study the fate of DMM in various environmental media and to simulate a hypothetical release from a leaking fuel-storage tank, respectively. The relative importance of water-based inhalation, ingestion, and dermal exposures was compared. DMM effectively reduced particulate emissions from a diesel engine. Its environmental behavior was comparable to that of MTBE. DMM could be used to handle the potential health risks of exposures to particulates derived from diesel-powered vehicles.
