title: [The emissions of fiber particles into the atmosphere in the region of an asbestos-processing industry].
abstract: Examination is carried out on dust taken from the atmospheric air in the town of Sevlievo, where a plant for asbestos products is situated. The concentrations of fibre particles are determined by the methods of light and electron microscopy. The results are compared with the emissions of fibres in the air of a control town. There is a significant contribution of an industrial source of emission in the atmospheric pollution by fibre particles. It was proved that the method of light-phase contrast microscopy is not suitable for analyses of low concentrations of fibres in the air. As only reliable method is that of electron microscopy.
