Opis:: The monitoring of greenhouse gases originating from different sources will be a crucial problem during this century. Experiments have been performed in order to obtain stable isotope composition of CO2 emitted by large industrial off-gas emitters. A special set for sample collection in field conditions was designed and tested. Two different methods of CO2 extraction were elaborated: vacuum extraction and extraction with carrier gas. Preliminary results of CO2 stable isotope composition emitted from an electric power plant during one working season are presented.

Opis:: The possibility of application of naturally existing differences in isotope contents 18O/16O, 2H/1H in waters for investigation of transport and mixing of various waters in the tributary-river system is presented. Experiments carried out on the Bug-Narew rivers-Zegrze Lake and the BugoNarew-Vistula rivers systems have indicated that the hydrogen isotope ratio 2H/1H can be used as an intrinsic tracer of natural mixing processes occurring in rivers. The IRMS methodology was used for isotope ratio measurement of water samples. The degrees of water mixing as a function of distance from the confluence point of rivers were determined. The obtained results indicate that in water systems where the natural differences in ?2H are higher than 5‰ this technique can replace the time-consuming and expensive dye (or radiotracer) dispersion tests for evaluation of pollutant transport in rivers.
