title: Comparative measurements of suspended particulates using several gravimetric methods and the British smoke sampler.
abstract: Comparative measurements by gravimetric methods and the British black-smoke method show that the black-smoke method is less precise than the gravimetric methods. The present studies reveal that the black-smoke device only separates fractions of suspended particulates up to a particle size of 1 micron. Separate evaluations of data sets measured over a period of a year and, during the winter, in accordance with the "Council Directive of the EC on air quality limit values and guide values for sulphur dioxide and suspended particulates" showed different correlations and relations to values established gravimetrically. The black-smoke method proved to be unsuitable for the evaluation of ambient air concentrations of suspended particulates by comparison with limit values.
