Review: Particulate Matter Emissions from Aircraft

The contribution of aircraft operations to ambient ultrafine particle (UFP) concentration at and around airports can be significant. This review article considers the volatile non-volatile elements particulate matter emissions from engines, their characteristics quantification identifies gaps in knowledge. current state art emission inventory methods dispersion modelling approaches are reviewed areas for improvement research needs identified. Quantification engine (nvPM) is improving as measured certification data landing take-off cycle becoming available. Further work needed: better estimate nvPM during full-flight; non-regulated (smaller) engines; evolution particles (vPM) exhaust plume. Dispersion improvements also needed address vPM. As both vPM sources improve, estimates concentrations will possible.
