    Measurements were made of sulphur and oxygen isotope ratios of sulphate in some Slovenian rivers, lakes and tap waters. delta S-34 ranged from -0.2 to +13.3 parts per thousand, delta O-18 ranged from + 4.9 to + 13.6 parts per thousand, and the sulphate content varied from 0.8 to 41.4 mg/L. Rivers. owing from the Julian Alps contain a very low amount of sulphate that is leached from a thin horizon of soil by rain. As confirmed by their low delta O-18 values, these sulphates do not enter the rivers directly in rain, but arise from biochemical cycling in the soil. The low delta S-34 of this sulphate indicates that it originates from the oxidation of sedimentary sulphides. The evolution of sulphates along the river course was investigated for the Sava and Ljubljanica rivers. The variations observed in sulphate from the waters studied result from variations in the contribution of sulphates of different origin. Downstream the Sava River sulphate is depleted in the heavy isotopes of both sulphur and oxygen, with delta-values gradually tending toward the delta-values of groundwater sulphates in the watershed. In contrast, the delta-values of sulphate in the Ljubljanica River are almost constant and similar to those of sulphate in local groundwater. Introduction of water from Italian and Slovenian mines was recorded in the Soca River, where the lowest delta S- 34 value of sulphate sulphur (-0.2 parts per thousand) was observed. In addition, the influence of sulphate from the oxidation of sedimentary sulphides was recorded in the Sotla River. No evidence was found for introduction of sulphate from factories.

    We provide the results of 24-hour observations made in a meadow site located in a small river valley in Central Europe. Samples of atmospheric air were taken from three horizons: near the soil (0.05 m), in the grass (0.5 m) and above the meadow (2 m) at two-hour intervals. At the same time, samples of soil air were collected from two horizons: -0.1 and -0.5 m. We have found a variation of delta(13)C above the ground from -6 parts per thousand during the day to -20 parts per thousand late at night accompanied by variations in CO2 concentration from 270 ppm during the day, to various levels late at night at different heights above the ground. The maximum concentration was 1430 ppm at the ground level. The correlation coefficient between delta(13)C and reciprocal of concentration was the highest (R-2 = 0.984) for the samples collected 2 m above the ground, the regression line clearly indicating CO2 mixing from the two sources: atmospheric and biogenic reservoirs. The intercept of the mixing line yields delta(13)C -23.0 parts per thousand for the biogenic CO2. In contrast, the diurnal variations in the soil were relatively small, delta(13)C varied from -21.6 to -23.4 parts per thousand, while CO2 concentration from 4300 to 8200 and from 24 700 to 34 500 ppm at depths of 0.1 m and 0.5 m respectively, which is less than 2-fold. Small diurnal variations are characteristic of dry soils, where delta(13)C is weakly correlated with CO2 concentration (in our case R-2 was 0.30 and 0.54, respectively).

    The isotope composition of sulphur and oxygen were measured in water collected from the Central Roztocze (SE of Poland) rivers. The research focused mainly on the upper section of the Wieprz River, its confluences and springs and on two confluences of the Tanew River. The results proved that there are two sources of sulphate dissolved in water: the Cretaceous aquifer and soil within the catchment's area. Seasonal variation of the sulphate concentration together with sulphur and oxygen isotope composition was observed. The isotope composition of sulphate varied in water collected at the different locations of the same river. They are similar for sulphates in springs and rivers. The isotope composition of sulphate varied in water collected at the different locations of the same river. The delta(34)S values of sulphates in the Wieprz River are the lowest (negative) in lower part of the river. It shows that the contribution of sulphate from spring water increases downstream. The low sulphate content and high delta(34)S and delta(18)O value in sulphates was found downstream from dams. It may be the result of deficiency of oxygen in mud and the reduction in bacteria activity. The seasonal variations of the oxygen isotope composition in sulphate are significant in sulphates collected from rivers and from springs. They are caused by seasonal variations of the delta(18)O in water stored in the soil. The narrow range of the delta(18)O values for the sulphates extracted from springs at the same time means that the main source of sulphate in spring water are oxidising processes using the same source of oxygen in every location. The high sulphate content combined with the high delta(34)S values of the sulphates in springs suggest, that the sulphates from Cretaceous aquifer were mixed with sulphates dissolved from the soil.

    Springs on Roztocze and Lublin Upland have been studied. Isotopic data are compared with data of chemical analyses. The results of studies allow us to distinguish five types of groundwaters. The differentiation is based upon different lithology; opokas, gaizes, sandy-silty-clay deposits, sands with shell sandstones, marly opokas, marly limestones' and soft limestones of chalk type. A correlation can be observed between delta(34)S and the concentration of Ca or Mg ions also a correlation between HCO3- ion concentration and delta(18)O in sulphates. Probably these correlations are the result of some simultaneous processes, which occur in groundwater. The seasonal variations of the isotopic composition and sulphate concentration were observed in four springs feeding the upper Wieprz. The variations were simultaneous and often similar in these springs. Probably, these variations are caused by the admixture of sulphates coming from shallow water layers (or leached from soil); however the variations of the groundwater level may also change chemical and isotopic composition in groundwater.

    The natural process of sulphate reduction takes place in the Rontok Pond. During the reduction the concentration of sulphate in the pond water decreases. The changes of delta S-34 in the pond water are typital for bacterial reduction. The reduction process in the Rontok Pond causes dissolution of barium and the radium from the pond sediments into the water. Concentrations of barium and Ra-226 in the discharged water from the Silesia Coal Mine are lower than in water flowing out of the Rontok Pond into the Vistula River. The opposite trend is observed for iron and also Zn, Co, Ni, Mn, Al and Cu because of the precipitation of ferric hydroxide in the stream. The reduction process, which causes dissolution of barium and radium in water, can explain the release of these elements into the Vistula River. The dissolution of toxic elements can be reduced by the precipitation of nontoxic deposits on the sediment of Rontok Pond.

    This research deals with pollution impact on natural water resources in the industrial area of Belchatow, central Poland, where a large brown coal deposit is exploited and the coal is burned in an electric power plant. To trace the sources of groundwater pollutants the stable isotope analysis of oxygen and sulfur in sulfates was applied. The mass-spectrometric analysis was performed on SO42- samples from numerous wells and piezometres in the excavation area. By repetitive sampling performed in November 1994, May 1995 and December 1996 significant changes of SO42- concentration and sulfur and oxygen isotopic ratios in several sites were recorded. The interpretation of isotope ratios allowed us to recognize three groups of sulfates: (1) from the leaching of Permian salt dome; (2) produced by the leaching of soluble sulfates from an ash pool and (3) produced by oxidation of natural sulfides in water-bearing rocks.

    In the hydrosphere sulfates of the following origin may exist: (1) evaporitic; they come from the leaching of sulfate rocks, (2) biological; formed by sulfur-oxidizing bacteria and (3) anthropogenic, which get into water with wastes, fertilizers ol acid rains. Chemical analyses map reveal sulfates in water, but their origin cannot be assessed by means of chemical analysis. The sulfates of various origin may differ in their isotopic compositions. However, sometimes we can observe the similarity of delta(34)S of sulfates whose origin was entirely different. This similarity may be so suggestive that it could be misleading. This paper presents patterns of completely different sulfates whose delta(34)S are similar, though they have nothing in common. Other tables present patterns of sulfates whose origin is similar or even the same but their delta(34)S are characterized by great variety. All of the isotopic data presented in the tables were specially chosen from some of the results of the studies of the sulfates in waters in Poland. Isotopes techniques are becoming more popular and are useful for studies in many fields. These patterns may be a warning against drawing hasty conclusions from the results of delta-measuring.
