ABSTRACT: This
paper describes a study into the development of more robust dust emission
factors by means of dust and meteorological monitoring. Emission factors for
nuisance dusts in the literature are scarce, with estimates of dust output
given for many processes in mass per unit area per year. Temporal variations
and the extent and conditions in which maximum concentrations occur can
therefore be impossible to predict with any accuracy. This investigation aims
to improve predic-tions by “back calculating” emission levels based on dust
monitoring around known dust sources. Nuisance dust and meteorological
monitoring has been undertaken at a sand and gravel quarry in the UK for a
consecutive period of two years. Sticky pad directional dust monitors were used
to collect dust at eight locations at and around the site with meteorological data
collected at an elec-tronic weather station within the site. Air quality
modelling software (ADMS) was used to test emission factors from the European
Environment Agency (EEA) and the US Environmental Protec-tion Agency (EPA) for
emissions from mineral workings. Predictions were compared with the dust
monitoring data to assess accuracy, with results showing limited poor
correspondence (r2 2 0.89) and similar maximum concentrations (
