Rahn	Diurnal variations of aerosol trace element concentrations as determined by nondestructive neutron activation analysis	1971	12	.pdf	application/pdf	3372	891	83	Abstract-Diurnal concentration variations of 20 trace elements in surface air have been studied particle size distribution of some elements suggested local sources. A STUDY of the diurnal concentration variations of atmospheric trace elements has high purity filter (DAMS, 1970) in which up to 33 elements may be determined from 24 Particle size distribution of the elements were determined by use of an Andersen sample, compare them with standard spectra, subtract blank values, calculate concentrations of the elements in air and standard deviations on the obtained results. 5, Concentration variations of 6 elements during sampling. 7. Particle size distribution of 5 elements as measured with an Andersen Impactor. 7. Particle size distribution of 5 elements as measured with an Andersen Impactor.
