This paper describes some characteristics and properties of low molecular compounds - labile fraction, isolated from dissolved organic matter in ground and surface waters on arable land. The differences in composition of labile fraction using IR spectroscopy were studied. Also, the ability of labile fraction to heavy metals complexation was analyzed.

In this work the energetics of water transport along the radial path of bean root (Phaseolus vulgaris L) and water elevation along the xylem induced by osmotically generated root pressure was studied. The radial path of the root was, according to Fiscus's concept [1,2], approximately modelled by a 1-membrane system. An analytical method by Kargol [5] (concerning the osmo-diffusive conversion of free energy) and data from a work by Steudle [9] (on permeation parameters of the root, i.e., filtration coefficient Lp, reflection coefficient a and permeability coefficient co) were applied in this study. This work shows that the energetical efficiency of the root of that plant does not depend on concentration, C0 of the root bathing solution (the medium) within the concentration range: 0

Numerical simulation experiments with a high-resolution circulation model were carried out to study nutrient transport from different depths to the surface 10-m layer during an upwelling event along the northern coast of the Gulf of Finland in July 1999. The initial nutrient distribution is based on field measurements performed in the north-western part of the Gulf. Wind forcing covering the period of the upwelling along the northern coast was turned through 180◦ to simulate an upwelling along the southern coast. The simulation results showed that the main phosphorus transport to the upper 10-m layer occurred from depths shallower than 30 m for the upwelling events along both the northern and the southern coasts. Nitrogen transport to the upper 10-m layer was the largest from depths of 40–55 m for the upwelling along the northern and 40–65 m for the upwelling along the southern coast. Simulated cumulative volume transports to the upper 10-m layer from different depths showed that the contribution from deeper layers was larger in the case of the upwelling along the southern coast. The reduction of wind stress had a bigger influence on water transport from the deeper layers.

Bottom-mounted acoustic Doppler current profiler measurements indicate that the net transport of water (844 m3 s−1) in the Little Belt makes up only 6% of the total transport between the Baltic Sea and the North Sea. This is a smaller percentage than the 9% commonly found in the literature. Owing to barotropic and tidal currents the gross transport is 5 times larger. The net transport is directed towards the North Sea mainly in the top 32 m of the water column but towards the Baltic Sea it occurs in the lower 5 m of the water column. The resulting transport of phosphorus is strongly affected by vertical mixing in an area of hydraulic control in the narrow part of the Little Belt. Comparisons of phosphorus profiles in stratified waters and in the mixing area indicate a yearly entrainment of 15 tonnes P from the bottom water to the surface layer. This vertical transport of P forms part of an internal loop in the general transport between the Baltic Sea and the North Sea. Compared to the transport observed 15–16 years ago, the present net phosphorus transport of 163 tonnes yr−1 from the Baltic Sea through the Little Belt is substantially lower.

W badaniach wykorzystano korzenie żyta ozimego odmiany Rostockie. Wzrost i rozwój roślin odbywał się w kulturach wodnych o pH = 7, przy ściśle kontrolowanym składzie pożywki Hoaglanda, w cyklu dobowym 16 h nocy / 8 h dnia, w temperaturze 296 K (dzień) i 289 K (noc). Izotermy adsorpcji-desorpcji wyznaczano dwoma adsorbatami: parą wodną i azotem. Wielkość powierzchni właściwej korzeni wyznaczano w oparciu o teorię adsorpcji BET. Wielkość powierzchni właściwych badanych korzeni wyznaczane niepolarnym adsorbatem – azotem były mniejsze od wielkości powierzchni właściwych oznaczanych parą wodną – polarnym adsorbatem. Nie odnotowano istotnego wpływu stopnia rozdrobnienia materiału korzeniowego na wielkości powierzchni właściwej. Wielkości powierzchni właściwej korzeni wstępnie suszonych w 378 K były mniejsze niż wielkości powierzchni właściwej korzeni suszonych w 303 K.
