Opis:
The author investigated a 0-3 cm layer of two forest brown soils: brown acid and brown leached. These forest soils were under handsome beech trees (Fagus sp.) between 100 and 120 years old. The author compared the chemical properties of the soils. The soil existing near the tree trunk (1 m2 of surface, strongly washed by rain water polluted by chemical substances) and the soil existing under the tree umbrella (40 m2 of surface in the area of the tree-tops, washed poorly by rain water). This comparison showed changes in these properties, dependent upon the degree of atmospheric contamination. It was found that, at the same level of atmospheric contamination, higher changes of properties were found in brown leached soil than in brown acid soil. Less acidified soils (with alkaline or neutral pH reaction) are more suitable in these researches. The investigations of the forest soil layer 0-3 cm (12 soil profiles) showed that changes in their chemical properties in relation to tree trunk-tree umbrella can be the basis of assessment of the degree of atmospheric contamination.

Opis:
In the study, the content of heavy metals such as Pb, Cd, Ni, Cu, Zn and Mn in the soils collected from various regions of the Lublin Voivodeship was examined. The examined soils were light medium soils. Content of individual elements was determined by the AAS method in the extracts of 1 M HCl. The analysed soils were poor in copper and manganese. Their concentration and the concentration of lead, cadmium and nickel was in the lower realms of the range natural for light soils formed from sands. Only the content of zinc was fairly high in the above soils, frequently as high as the first degree of contamination.

Opis:
Concentration and profile distribution of heavy metals was investigated as contamination indicators of the forest soils formed from glacial deposits of the South Podlasie Lowland. The study was carried out on thirteen soil profiles situated a hundred meters from the road. The highest content of heavy metals was found in the organic horizons of the investigated soils. The mean content of Mn, Zn, Cu, Pb, Ni, Cr in the investigated soils were: 556.7, 72.9,15.5, 63.5,13.8, 16.5 mg/kg d.m. of the soil, respectively. In the mineral-organic and mineral horizons of the investigated soils heavy metals were present in quantities which were close to natural. The podzol soils, podzols and rusty soils developed from sands contain less heavy metals than the soils lessivés, black earth and deluvial soil. The Mn, Zn, Cu, Pb distribution in the soil profiles is influenced by the soil forming processes. The distribution index of the examined metals distribution in the genetic horizons testify to it.

Opis:
This study was based on tuber samples from the field experiment in 1996-1998 on weak loamy sand soil in a system of randomised sub-blocks. The experimental factors were: ways of nursery and varieties (Swojecka, Kulista Czerwona IHAR, Kulista Biała IHAR). Herbicide application elevated both cadmium and nickel contents in Helianthus tubers as compared to control. Tubers of Swojecka Czerwona cv. were characterised by the lowest accumulation of cadmium and nickel, those of Kulista Czerwona IHAR cv. by the highest content of nickel, and those of Kulista Biała IHAR by the highest level of cadmium.

Opis:
The content of Cd, Pb, Cu, Ni and Cr was analysed in the soil layers of 0-20 and 21-40 cm originating from four fruit growing farms localised in the area of Wielkopolska. The analyses have shown that the content of all the investigated heavy metals both in the arable soil layer and in the subsoil, was lower than their natural content in the Polish soils. The phenomenon of decreasing Cd, Cu and Pb content, and increasing Ni values in the deeper soil layers as compared to the arable layer was observed.

Opis:
In the present paper arable soils of the Upper Silesia were evaluated as to copper, zinc, manganese and iron contents, determined in the same extract, i.e. 1 M dm-3 HCl. The studies comprised 20 points in the vicinity of Sosnowiec and 20 points from near Zawiercie. Soil abundance in the available forms of microelements was assessed on the basis of the limiting numbers suggested by the Institute of Soil Science and Plant Cultivation. Soils of Zawiercie and Sosnowiec belonged to those with high contents of zinc in all the cases; in the majority of objects these were the soils with medium contents of copper and manganese. In half of the cases, the soils were classified as possessing low iron content, and in the remaining half as having medium iron content.

Opis:
Research was carried out in 1998 on the area of 10 allotments situated within the limits of the city of Lublin. Representative soil samples, as well as samples of white cabbage and carrot roots were collected. Content of lead, zinc, and copper were analysed in the samples. On the basis of chemical analysis, it was observed that quantities of lead and zinc were usually higher than average in the same type soils in non-polluted areas. Copper content in the soil did not exceed the average values. The natural content of metals was usually not exceeded in plants. However, samples of white cabbage taken from the "Nasza Zdobycz" and "Sygnał" allotments, where the amount of lead was higher than I mg kg-1 of dry mass were an exception.

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:
Studies on the possibilities of activating heavy metal ions by platinum ions in the soil have been undertaken. The present work gives results of research on the copper ions activated in loessial soil by the treatment with solutions containing platinum ions. Samples of podzolic soil developed from loess were collected from the horizon Ap (0-20 cm). The samples were treated with re-distilled water or with the same quantity of PtCl4 water solutions containing 2, 4, 20 mg of platinum ions. Soil reaction (pH) was measured after 1, 2, 3, 4, 5 and 6 months of incubation at 5 and 20 °C temperature. Copper ion content was determined in the filtrates using the technique of atomic absorption spectrometry. The amount of copper ions activated in the soil material depended on the soil reaction, temperature, quantity of platinum ions introduced and the time duration of the experiment.

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.
