[Occupational exposure to n-nitrosamine in the production of automobile tires]. / Narazenie zawodowe na n-nitrozoaminy w przemysle opon samochodowych.

Applying the method for determining nitrocompounds, based on gaz chromatography technique with nitro-phosphoric detector, N-nitrosodimethylamine, N-nitrosodiethylamine, N-nitrosodibutylamine, N-nitrosotetrahydropyrrole were detected in the work environment of the plant under study (method of determining 0.2 micrograms/m3 for 1000 l/air). For qualitative purposes the data obtained were supported by mass spectrometry. Measurements of individual exposure were taken in 35 persons and stationary measurements were also applied. Among nitrosamines detected, N-nitrosodimethylamine (carcinogenic substance) occurred most commonly at working post, and its concentration was the highest (2.1-9.2 micrograms/m3).

[Reliability of routine measurements of atmospheric air pollution using sulfur dioxide as an example]. / Wiarygodnosc analiz podstawowych zanieczyszen powietrza atmosferycznego na przykladzie dwutlenku siarki.

On the basis of an external quality control of sulfur dioxide measurements in the atmospheric air (emission), the preparation of control material, its evaluation and a two-week durability of the material are presented. The results of the control test carried out in autumn 1994 is also discussed.
