[Recent developments in pollutant dosimetry with special reference to water soluble gases].

The paper describes special problems of sampling toxic gases, very soluble in water, on workplaces with passive samplers. It is possible to construct such passive dosimeters which are suitable for the measurement of substances mentioned above if some peculiarities are taken in consideration. The stain-length passive dosimeters are specially analysed. Problems of the accuracy of this dosimeters, caused by inconstancy of the response time, are explained.
