    Abstract

    Aerosols were monitored in Greater Copenhagen in the period June 1973 to July 1 974. Size-fractionated cascade impactor samples and unfractionated filter samples were regularly collected and analyzed by neutron activation analysis, spark emission spectroscopy or proton-induced X-ray emission spectroscopy. Concentrations were determined of the following elements: Al, Si, S, CI, K, Ca. Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Mo, Cd, Sn, Sb, and Pb. All elements showed orders-of-magnitude fluctuations; the mean concentrations were roughly the same as in other large cities. In relation to proposed air quality standards, Pb was the most critical component. Statistical analysis of variation patterns, size distributions and interelement correlations indicate that automotive exhaust is the source of Br and Pb; fuel-oil combustion is the main source of V and Ni (and partly of S); soil dust raised by wind or by human activity (e. g. traffic) is the main source of Al, Si, Ca, Ti, and Fe.
