[Measurement and evaluation of air contamination by dust in the Federal Republic of Germany].
The paper presents hygienic standards, either currently valid in the GFR or planned to be introduced in 1982, for industrial dusts containing free crystalline silica and asbestos. In addition, methods and apparatus for measuring dust respirable fraction concentrations at workplaces are discussed, as well as principles of work conditions evaluation and hygienic interpretation of measurements results. The basis of this interpretation is an assumption that the MAK (Maximale Arbeits-platzkonzentrationen) values for the dusts containing crystalline forms of silica and TRK (technische Richtkonzentrationen) for the dusts containing asbestos are average values for 1 year. Dustiness at workplaces is also evaluated for 1 year.
