ESTIMATES OF THE CONTRIBUTION OF FOG WATER TO WET ATMOSPHERIC DEPOSITION IN CZECH MOUNTAIN FORESTS BASED ON ITS STABLE HYDROGEN AND OXYGEN ISOTOPE COMPOSITION: PRELIMINARY RESULTS
Original language description
Stable isotopes are increasingly being used in many scientific fields, including environmental sciences. In this study we measured the variation in the stable hydrogen and oxygen isotope composition of fog water, rain water (in the form of bulk falling precipitation) and throughfall water in the Sumava (the Bohemian Forest), Krkonok (the Giant Mts.) and Jizerske hory (the Jizera Mts.) Mts. in October-November 2017. In total, 46 cumulative two-week samples were collected and analysed. Our results indicate that the overall stable hydrogen and oxygen isotope composition of fog and rain samples differed significantly, fog being isotopically enriched in the heavier isotopes H-2 and O-18 relative to rain. In contrast to our assumption, throughfall water was generally depleted in the heavier isotopes H-2 and O-18 relative to rainwater. Hence, the simple mixing model for most samples yielded an unrealistic percentage outside the reasonable range of 0-10096. For few samples, however, the estimated contribution of fog to throughfall ranged between 3 and 8% based on delta H-2 and 4 and 7% based on delta O-18, which is lower than that estimated for the same mountain regions by other authors using different methods and significantly lower than that reported for mountain ranges in neighbouring countries. Although using stable isotopes is a promising tool for determining the contribution of fog to the hydrological budget when assessing atmospheric deposition, the critical limitations are in the collection, manipulation and storing of the samples.
