At present, the sediment/water interface is characterized by a sharpy delineated anoxic sediment/oxic water column interface zone, indicating most recent shift to moderate eutrophication.

In connection with the groundwater vulnerability mapping in karst areas, the aim of the study is to investigate the permeability and retention properties of fine-grained soils in brezovske karpaty Mts. and Slovensky Kras (Slovakia) and on the Istrian peninsula (Croatia).

There, the degree of the ground-water vulnerability depends not only on the thickness, but also on the hydraulic conductivity and retention properties of the soil cover. The hydraulic conductivity of fine-grained karst soils was studied within several international research projects. In the paper, results are discussed from different points of view.

Saltpans, like fish tanks which are considered a reliable method for acquiring RSL index points, are also anthropogenic intertidal facilities, used continuously in the Mediterranean from early antiquity. The Dalmatian shore contains a large number of preserved and historically dated ancient saltpans, now flooded by the rising sea, providing great potential for past RSL indication. The primary objective of this study is to develop a new holistic approach for producing high quality elevation measurements of the saltpan structures and estimating paleo RSL during the last 2 ka. The study combined aerial photogrammetry of the site, bathymetry acoustics scanning, and underwater archaeological survey of the manmade structures, as well as sampling wood and mortar in situ where available. Evaluation of each site's RSL and the functional height is based on the same assumptions and interpretations made for fish tanks, using elevation measurements on the top of the separation walls and the bottom of the sluice gates. In all the sites analyzed here, we achieved reliable digital surface models with continuous highresolution data on the indicative structures with single centimeters level of accuracy. The study finds that during the 5th-6th centuries, RSL was À92 ± 25 cm, increased to À62 ± 21 cm during the 7th-11th centuries, and decreased to À104 ± 20 cm in the 14th century. Medieval RSL can be explained either by strong tectonic subsidence post 1300 AD or by fluctuations as observed in the East Mediterranean, which requires validation by further Medieval indicators.

Medvednica NW of Zagreb, Croatia, obtained during an environmental regional geochemical study indicated that the sources of pollution were not only from Pb-Hg-Ba mining region situated along the upper course of the river Sava in neighboring Slovenia, but also in part from local historical mining sites located on Mt. Medvednica. As a target of this study was an old 17 century lead mine (galena with 485 ppm of Ag) situated near the chapel of St. Jacob (Croatian Sv. Jakob) on the crest of Mt. Medvednica (830m a.s.l.). The mineralization which consists of galena, sphalerite, pyrite and quartz occurs as irregular veins within Triassic dolomites. A total of 110 brown forest topsoil (0-25 cm) soil samples was collected on dense regular grid covering an area of approximately 1.5 km2. Ten samples were selected for detailed chemical and mineralogical analysis. Trace metal values were obtained from aqua regia extracts, while their residence sites in soils were identified by sequential extraction performed with the aid of a modified combination of procedures proposed by Tessier et al., (1979) and Hall et al., (1996). The following phases were defined by the reagents used: exchangeable, carbonate, iron and manganese oxide, organic-sulphidic and residual. The concentration trace metals in resulting solutions was determined by atomic adsorption spectroscopy and inductively-coupled plasma spectrometry. Total mercury was determined by flameless AAS mercury detector (AGP-1) from solid samples after heating at 700°C and pre-concentration with a gold wire (detection limit = 10 ngg-1).The aqua regia extractable Pb values varied from 9 to 18000 mgg-1, Zn 12-9000 mgg-1, Cd from Fe and Mn oxide> organic-sulphide> exchangeable = residual b) Zn organic-sulphide> Fe and Mn oxide> residual> carbonate> exchangeable c) Cd Fe and Mn oxide>carbonate=organic-sulphide> exchangeable>residual The mineralogy of the soils is dominated by quartz, mica, geothite, kaolinite and plagioclase, cerrusite was identified by XRD only in one sample and no primary sulphide minerals (galena) were found. The flooding of the river Sava (the last major flood occurred in 1964) is the major source of soil pollution in the floodplain area south of Zagreb, but the violent mudflows from streams that drain the areas of historical mining sites that occur after rainstorms and flood northwestern parts of the city, as this study shows, also present a probable source of pollution.

Therefore, groundwater is very suscesible to pollution in karst areas. Even some heavy metals can migrate to considerable distances through karst channels despite the buffering capacity of surrounding carbonates. soils are often the only cover of the carbonates and in that case the thicknes, the permaebility and sorption properties control the migration velocity of contaminants.
