Modelling long-range transport of primary particulate material over Europe

This paper uses a simple model of atmospheric transport and an emissions in ventory prepared by TNO to estimate the contribution of primary particulate material to PM10 and PM2.5 concentration across Europe. The resulting popu lation exposure is compared with that of secondary particulates, and it is noted that both primary and secondary contributions will be significantly r educed with the implementation of new protocols under the Convention on Lon g-Range Transboundary Air Pollution (CLRTAP). Since concentrations of prima ry PM10 can become elevated in episodic situations, when long-range transpo rt of particulate could, on its own, exceed 24 h average targets of 50 mug m(-3) over large areas of Europe, such reduction is important for achieveme nt of current air quality standards to control exposure to atmospheric part iculate PM10.
