Abstract
During the period May 1972-April 1975 the daily average levels of Pb, Zn, Cd, Ba, V, Ni, Mn, Cu, Cr and Fe were routinely determined at fifteen different stations by means of emission spectrography on dust collected on Whatman 41 cellulose filters in a specially designed high volume sampler. The main characteristics of sampling and analysis procedures are described and the most important statistical results for the elements under investigation are summarized. Comparison with similar results obtained by other investigators confirms the average range of the pollution in the country. Future trends in this five year programme are specified.
