Zusammenfassung:Aerosol mapping was used to assess particle number and mass concentration in an engine machining and assembly facility in the winter and spring. Number and mass concentration maps were constructed from data collected with two mobile sampling carts, each equipped with a condensation particle counter (10 nm < diameter < 1 μm) and an optical particle counter (300 nm < diameter < 20 μm). Number concentrations inside the facility ranged from 15 to 150 times greater than that outside the facility and were highly dependent on season. The greatest number concentration (>1 000 000 particles cm−3) occurred in winter in an area where mass concentration was low (
