The analysed area was used for industrial activity for over 130 years. During that time many pollutants (including heavy metals) have been emitted by industrial plants and infiltrated into the soil. This article presents the properties of the soil from industrial sites located in Zielona Góra and analysis of its physical and chemical characteristics.
Food intake, body mass index (BMI), serum lipids, blood glucose, systolic and diastolic blood pressure and pulse wave velocity were measured in the population of 2559 males aged 25-59 years employed in a foundry in Cracow in 1972-1974. Abnormal dietary habits were revealed. The share of protein in total energy intake was 11.7%, fats 37.1% and carbohydrates 51.2% (sugar 11.6%). The mean BMI was 25.3 ± 3.1 BMI above 25 was found in 44% of males under study. It has been shown that serum cholesterol, total lipids, esterified fatty acids, systolic and diastolic blood pressure, and pulse wave velocity were positively correlated with BMI. It is concluded that obesity prevention and treatment should be recognized as. an important method in prevention of coronary heart disease.
Four metals (Cu, Zn, Pb and Cd) were assayed in soils within the impact zone of the Miasteczko Slaskie Zinc Smelter (southern Poland). The investigated area is afforested and has been subjected for a long time to intensive deposition of metal-bearing dusts. Soil pHKCl varied broadly from very acidic (pHKCl = 3.4) to slightly alkaline (pHKCl = 7.2). Organic carbon (Corg) content fluctuated within a large range, i.e., 5.5 - 66.4 g kg-1, whereas the cation exchange capacity (CEC) was in most cases markedly low (from 1.4 to 5.9 cmol(+)kg-1), with exception for two sites (C and D) exhibiting values of 26.8 and 15.1 cmol(+)kg-1, respectively. Total Zn, Pb and Cd contents exceeded manifold their respective levels in the Earth crust (reference value - RV)) as well as those suggested as background levels for Poland (BLP). The assessment of the contamination of soils by these metals was undertaken on the basis of geoaccumulation indices (lgeo), contamination factors Cl and degrees of contamination (Cdeg). The overall metal contamination represented practically two classes: low contamination for Cu; considerable to extreme contamination (in ascending order) for Zn, Cd, and Pb. The contribution (BLP-based assessment) of each metal to the degree of contamination index varied from 2.14 % (for Cu), via 26.33% (for Zn) to quite equally for Cd and Pb, both representing 35.22% and 36.32, respectively. It is worth pointing out that copper was the sole metal to threaten the least (Figure 1) the soils of the investigated ecosystem.
This paper characterises S-SO4 concentration in the surface (0-20 cm) layers of the agricultural soils in Poland (45242 soil samples) and in the Lublin region (3648 soil samples). Mineral soils in Poland contain, on average, 1.79 mg of S-SO4/100 g of soil. In the Lublin region, it is 1.65 of S-S-O4/100 g of soil. In the whole of the country, 83.2% of the agricultural soils have natural (00 +10) levels of S-SO4; this includes the areas with very low (00) concentrations (58.1% of the agricultural land) as well as elevated (10) concentrations (25.1% of the agricultural land). Soils polluted with sulphur (20+30) make up 16.8% of the agricultural land. This includes weak (20) and heavy (30) pollution - 13.1 and 3.7%, respectively. In the Lublin region, 88.5% of the agricultural soils have natural (00+l0) levels of S-SO4 . This includes the areas with low (00) concentration (64% of the agricultural land) as well as the areas with elevated (1°) concentration (24.5% of the agricultural land). Soils polluted with sulphur (20+30) make up 11.5% of the agricultural land, including weakly (2°) polluted soils (8.7%) and heavily polluted (30) soils (2.8%).
