    Opis:
    The paper characterises total concentrations of Cd, Cu, Ni, Pb, Zn in the surface layers (0-20 cm) of agricultural soils in Poland (48620 soils samples) and Lublin region (3829 soil samples). The results for Lublin region are expressed in terms of the degree of metal pollution as compared to contamination in the rest of the country. The average concentration of Cd, Cu, Ni, Pb and Zn (in mg kg-1 of soil) in the A horizon of agricultural soils in Poland and in Lublin region (values in parenthesis) are as follows: 0.21 (0.17); 6.5 (4.9); 6.2 (6.6); 13.6 (10.7); 32.4 (23.3). About 79% of the agricultural soils in Poland are characterised by a natural (0°) content of heavy metals while 17.6% contain elevated level (10) of these metals. In the Lublin region it is 91.9% and 6.7%, respectively. About 3% of the Polish soils (1.4% in the Lublin region) exhibit various degrees of contamination with heavy metals. This includes heavy (IV0) and very heavy pollution (V0) which is found in up to 0.4% of the agricultural land and up to 0.2% in the Lublin region.

    Opis:
    On the basis of results obtained in 2 static experiments conducted on light and heavy soils with differentiated mineral fertilisation, an approximate balance of Cd, Ni and Pb was determined over 20 years of investigations. The experiments included 3 levels of fertilisers and the control plot. Ammonium nitrate, single or triple superhosphate and potassium salt were used for the treatments. Average amounts ofheavy metals introduced with the fertilisers in both experiments over twenty years were as follows: 37-110 g Cd, 63-195 g Ni and 62-202 g Pb ha-1. The balance ofheavy metals over twenty years assumed different values depending on the fertilisation level and soil conditions. However, irrespective of those factors, the balance assumes a negative value. The effect of nitrogen doses on the balance was slight and depended on the site trophicity. On the other hand, increasing doses of phosphorus and potassium treatment decreased the value of the negative balance difference of cadmium and, to a lesser degree, of nickel, but increased the lead balance.

    Opis:
    The subject of the paper was to determine chromium and cadmium fractions in the soils treated with tannery organic materials. Methods, characteristics of experimental materials and the tested soils were presented in the first part of the paper. After four years of investigations soil samples were collected for the assessment of the total content of chromium and cadmium and their fractions. Results of a sequential chemical extraction confirmed literature data on the weak mobility of this metal in the soil. After application of the studied fertilisers, the share of the most mobile Cr fractions was slight. Iron oxides and residual fractions were most important for chromium accumulation. Cadmium mobility in the soil and its easy uptake by plants is related to a considerable share of mobile forms. A large share of mobile form was noticed in the analysed soils (54.5-68.3%). Exchangeable fraction bound smaller amounts of cadmium (6.8-13.2%). Similar amounts of cadmium were accumulated in the fractions bound to manganese oxides (8.5-19.6%). Organic matter did not contribute to this element binding and the amounts of cadmium stored in this fraction were 2.3-6.6%. Only very small amount of cadmium was accumulated in the form bound with the initial minerals.

    Opis:
    The present experiments were earned out pn the soilrf of the Rybocice polder near Swiecko, which was purposefully flooded with waters of the Odra river during the summer flood of' 1977 that causet complete destruction of crops and meadow sward. The flooded areas remained under water for more than 30 days. The dominant soils found in this area are river alluvial soils (Fluvi- sols) of varying texture. Rceause of their location and poorly operating drainage system, the discussed soils are periodically too wet by nature or water-logged. In the spring (March/April) of 1998 the ground water table occurred at the depth of 30 cm on damaged grasslands and at 90 cm on some arable Holds. The content of organic carbon ranged from 0.7 to 3.2% in horizon A with depth of approximately 30 cm. Soil reaction was found to vary considerably - from pH (KCI) 4.2 to pH 7.6. Long purposeful inundation with flood waters was not found to have caused significant negative effects on chemical properties of the examined soils. No noticeable contamination with heavy metals (Pb„ Cu, Zn, Cd, Cr and Mn) or polieyclic aromatic hydrocarbons (PAH) was observed. Bulk density in this region, without any treatment from the period of flooding to the spring of 1998 was approximately 1.60 Mg/m3 as compared with 1.40 Mg/m3 on the field cultivated (ploughed) in spring and sown with spring cereal. The mean crop yield in 1998, when appropriate agro-techniques were applied, did not vary significantly from the long-term averages.

    Opis:
    The present investigations aimed at determining the effect of various organic materials, i.e. farmyard manure (FYM), organic tannery sludge and compost of such sludge and peat on lead, copper and nickel fractions content in soil. Doses of peat compost and organic sludge were calculated according to the nitrogen amount per a FYM dose. After four years of experiment, fractions of Pb, Cu and Ni compounds were assessed in the soil from individual plots using the Zeien and Brummer's sequence chemical extraction method. Heavy metal contents were determined using a ICP-AES in JY 238 Ultrace apparatus. Lead accumulated mainly in the form bound with organic matter and with amorphic iron oxides. This metal distribution reveals its slight share in the mobile and exchangeable forms. Composts and sludge introduced into the soil did not affect any significant changes of the individual lead forms share as compared to FYM and NPK treated plots and the control. Some amount of copper occurred as mobile forms in all the soils. In the soil of all the treated plots, copper occurred mainly bound with organic matter and amorphic iron oxides. The basic share of nickel was found in the residual fraction bound with internal crystalline nets of initial elements. Beside the residual form, nickel was connected mainly with organic matter.

    Opis:
    Przeprowadzono badania wpływu intensywności użytkowania rolniczego na zawartość wybranych mikroskładników w glebie: Cr, Cu, Ni, Pb i Zn. Obserwacjami objęto cztery typologicznie różne gleby wytworzone z pyłu: czarnoziem, płową, płową niecałkowitą i madę rzeczną. Na każdej z badanych gleb wyznaczono po pięć obiektów użytkowych: sad, chmielnik, pole, użytek zielony i las. Próbki glebowe pobierano z dwóch warstw z poziomów akumulacyjnych (Ap i Ah): 0 - 10 cm i 10 - 20 cm, oraz z głębokości poniżej 35 cm (z poziomów Bt i Ah). Oznaczono całkowitą zawartość mikroskładników w glebie (IPC-AES). We wszystkich glebach użytkowanych rolniczo stwierdzono podwyższoną zawartość badanych metali ciężkich, szczególnie na obszarach użytkowanych najbardziej intensywnie. Znaczące przekroczenie norm zasobności gleb w metale ciężkie, nastąpiło jedynie w dwóch przypadkach. Oba obiekty położone były na madzie a przekroczenia te stwierdzono w warstwie 0 - 10 cm (chmielnik - 138,5 mg Cu·kg⁻¹; sad - 144,0 mg Zn·kg⁻¹).
    The effect of agricultural land-use intensity on the content of selected heavy metals (Cr, Cu, Ni, Pb, and Zn) was studied. Four different soils developed from silt, e.g. chernozem, luvisol, non-uniform luvisol, and fluvisol, were analyzed. On each type of the soil studied, five different land-use forms were selected: an orchard, a hop-garden, an arable field, a grassland and a forest. Soil samples were taken from two layers of humus horizons (Ap and Ah): 0 - 10 cm and 10 - 20 cm, as well as at the depth below 35 cm (from horizons Bt and Ah). The total content of the trace elements in soil (IPC-AES) was determined. The increased content of the heavy metals studied was stated in the soils under agricultural management, particularly in the most intensively used areas. The standards for heavy metal content in soil (according to Polish standards - Inst. Soil and Plant Cult.) were exceeded only in two land-use forms, both situated on the fluvisol, in the layer of 0 - 10 cm (138.5 mg Cu·kg⁻¹ in the hop-garden; 144.0 mg Zn·kg⁻¹ in the orchard).

    The study is concerned with the course of sorption of Fe²⁺, Fe³⁺ and Mn²⁺ ions and with their washing, out with distilled water in sandy, loess, and loamy soils. Sorption was conducted according to the idynamic method. ODR and Eh were measured as indices of soil oxygenation. It was found that oxygen deficiency of the soils under study, with a change in their reaction from acid to neutral, resulted in: 1. an increase in the sorption of Fe²⁺ and Fe³⁺ ions, 2. an increase in the sorption of Mn²⁺ ions in the loamy soil only.

    Opis:
    Soil contamination of areas covered by industrial plants and farms is one of the major environmental problems whose weight is underestimated in Poland and Europe. Such regions are usually not as exposed to direct pollution as highly urbanized industrial areas. On the other hand, they are usually less strictly monitored than protected areas. The District of Olkusz, an example of such a region, is characterized by well-developed agriculture, regressing local industry and growing tourism industry. However, it borders with Silesia, a heavily industrized area. The study reports the condition of arable soils in Olkusz District in terms of their contamination with lead, cadmium, zinc and copper. The atomic absorption spectrometry (AAS) method was used to determine the concentrations of the metallic elements. The parameters like pH, content of the clay fraction and content of organic matter have been also taken in consideration to assess the bioavailability of the metals. The analytical results showed that, despite the decreasing impact of the local industry, levels of concentration of all the studied metals are significantly higher than their average concentration in Polish soils. Moreover, all the calculated Pearson correlation coefficients between concentrations of the metals were above 0.9, which means they correlate each other strongly. The impact of the local pollutants (mainly Bukowno smelter) in connection with the proximity of the Silesia and the high vulnerability for contamination of the soils precludes agricultural use of the ground in at least half of the cases.
