The main aim of the study was the determination of the content of selected metal ions in soils originating from Polesie Lubelskie and Biebrza River Region, as well as an attempt at relating the results obtained to the degree of secondary transformation of studied soils. All the soils belonged to peat-muck soils and differed from each other in their secondary transformation index. The study included analyses of the content of potassium, calcium, magnesium and manganese with the use of absorption atomic spectroscopy for the determination of the concentration of those metals. At the next stage of the study, relationships between the secondary transformation index of peat-muck soils and selected metal contents were examined. Weak linear relationships were found for the secondary transformation index and the content of calcium, manganese and potassium. A more complex situation was observed for the relation of magnesium ions. The lack of a straight-line trend could be explained in this case by the effect of chemical processes occurring in particular classes of mucks transformation on magnesium ion binding.
The aim of this study was to find out if cigarette smoking influences the Cd, Cr, Cu, Fe, Mn, Pb, Zn, K, Na, Ca and Mg contents and mutual relationships between these elements in teeth. The content of elements was determined by means of atomic absorption spectrometry in the smokers' and non-smokers' teeth. It was concluded that the cigarette smoking results in the significant increase of Cd, Zn and Cu contents in teeth and that the supply of heavy metals from cigarette smoke to human organism influences the mutual relationships between the elements in a tooth structure.
The aim of our study was to estimate the influence of mineral fertilization on the contents of various copper and nickel forms in soil. It was based upon a field experiment made up of ten plots. In average soil samples taken in 2002-04, the pseudo-total copper and nickel content was determined. Chemical forms of these metals, by modified BCR method, were also determined. The nickel content in particular fractions can be arranged quantitatively (average values) in order as follows: F2 (21%) > F3 (18%) > F1 (8%), in the case of copper: F2 (37%)>F3 (14%)>F1 (11%). The accumulation of nickel in the soil during the experiment was not observed. Whereas slight copper accumulation in some plots (with Polifoska 6, Polimag 305, calcium sulfate tetraurea and phosphogypsum) was noted. During the experiment the most mobile nickel and copper forms (soluble + exchangeable fraction) increased.

The contents of cadmium, lead, zinc and copper were determined in 64 samples of produce (19 strawberries, 16 tops of parsley, 16 dills, 13 lettuces). The produce was gathered directly from home-gardens located near Opole, Wroclaw, Legnica and Jastrzebie Zdroj. The content of cadmium found was within the limits 0.0027–0.663 mg/kg. The contents exceeding the allowable value were found in three samples of dill. The determined quantity of lead ranged from 0.0047 mg/kg to 0.588 mg/kg and the exceeding of allowable contents was found in two dill samples, two lettuce samples and one parsley (greens). The level of zinc contents was between 0.716–34.76 mg/kg. In fourteen samples (3 parsley, 2 lettuces and 9 dills) the limits established before 2004 were exceeded.The contents of copper in produce was within 0.342–17.03 mg/kg. In seven samples (3 parsley and 4 dills) the allowable quantity of Cu established before 2001 was exceeded. The highest amount of cadmium and copper was determined in samples taken near Jastrzebie Zdroj, while the largest quantity of lead and zinc was found in the produce collected in Legnica. The relatively smallest quantities of metals were found in the samples collected near Opole. A comparison of collected data with those available in the literature shows that the recorded level of contamination of the tested produce with heavy metals is close to levels determined for other industrial regions of the country but higher than the world’s standards.
Corms of Colchicum autumnale L. (meadow saffron) from plants growing on soils developed from five parent materials (melaphire, serpentine, sandstones, limestone and marls) were collected and analysed to evaluate their colchicine content as well as metal levels (Fe, Mn, Zn, Cu, Pb, Co, Cd, Ni and Cr). For all locations, (mountainous regions in SW Poland far from pollution sources) where corms were collected, soil samples were taken. In the soil samples, the concentration of elements (Fe, Mn, Zn, Cu, Pb, Co, Cd, Ni and Cr) was analyzed and also soil pH, organic matter content and sand, silt and clay content were determined. The results of principal component analysis (PCA) showed that the concentrations of metals in melaphire (except Cr), sandstone and serpentine soils were higher than those in limestone and marl soils. Meadow saffron corms tended to take up a higher amount of Fe and a lower amount of Co and contained in their tissues a higher amount of colchicine in melaphire soil and some sandstone soils than those in limestone and some marl soils. The concentrations of Co, Mn and Zn in corms at limestone site and Ni and Cd in corms at serpentine site and some marl sites were higher than those in other sites. The results of stepwise regression analysis showed that colchicine corm concentration as well as corm Fe content increased with increasing soil Fe, Mn, Zn, Co, Cu, Pb and Cd contents and that corm Fe content has a positive effect on the production of colchicine, whereas corm Co, Mn, Zn, Ni and Cd negative. The corm Fe, Mn, Zn, Co, Ni and Cd concentrations appeared to be the main factors determining the variation pattern of colchicine in C.autumnale corms. The variation explained by these selected variables was higher (79%) than those explained by selected soil variables (53%).
Bottom deposits of selected rivers in the Świętokrzyskie Region of Poland flowing through areas of various geological characteristics and land development were analyzed for the presence of cadmium, zinc and lead. Microwave-assisted 3-stage sequential extraction recommended by the European Union (EU) was applied for that purpose as well as a 5-stage extraction proposed by Tessier et al. Residues after sequential extraction were mineralized in concentrated nitric acid in order to check if applied sequential extraction procedures allowed extraction of total amounts of metals from bottom deposits. Metal contents were determined with F-AAS technique in particular extracts.
The environmental study, carried out in the Lublin region, was aimed at assessment of strawberry fruit quality based on the contents of heavy metals (Pb, Cd, Ni, Zn, Cu, As, Hg) and finding correlation between these heavy metals and some properties of soil and plant. Heavy metals in soil and fruits were determined with ASA method, other analyses according to research procedures of the laboratory of the Regional Agrochemical Station in Lublin. Region of cultivation has no significant effect on the contents of heavy metals in strawberry fruit. Some soil properties have significant effect on occurrence of mainly zinc and mercury and, to a slightest degree, also cadmium and copper in the plant. In the fruits, contents of copper and zinc and, to a slightest degree, also cadmium, nickel, mercury, and lead were dependent on occurrence of other elements in this part of the plant. The average contents of heavy metals in strawberry fruit grown in the Lublin region (0.023 mg Pb, 0.020 mg Cd, 0.091 mg Ni, 1.228 mg Zn, 0.358 mg Cu, 0.0015 mg As, 0.00011 mg Hg kg⁻¹ of fresh matter) indicates that it did not exceed upper threshold of products of this type.
Metal intake abilities of Euphorbia macroclada, Verbascum cheiranthifolium Boiss and Astragalus gummifer, which are common and native throughout Turkey and similar locations, were studied in the heavily polluted Keban mining district in Elazig, Turkey. For this aim metal contents of dried plants and soil were determined and correlated. Soils of Keban area have higher than average values for soil, Mo, Cu, Pb, Zn, Ag, As and Cd contents. All the studied plants take up metals in high amounts - as high as hundreds of times more than averages for non-hyperaccumulator plants. Usually, higher plant metal contents are attained where higher soil metal contents exist. Enrichment factors, which are calculated by dividing metal contents of plant by metal contents of soil (= metal content of plant/metal content of soil), are higher in lower soil metal contents. Maximum metal contents in the shoots (as mg kg⁻¹) and enrichment factors for Euphorbia are: Mo 260-1.28, Cu 33-0.18, Pb 76-0.09, Zn 190-0.51, Ag 0.53-1.1, Mn 276-0.28, As 10.2-0.08, and Cd 0.20-0.13. For Verbascum: Mo 80-0.83, Cu 27-2.87, Pb 295-1.57, Zn 254-1.78, Ag 0.37-0.92, Mn 627-0.58, As 63.5-0.50 and Cd 0.59-1.25. For Astragalus's gummufer: Mo 402-0.98, Cu 30-0.95, Pb 552-0.82, Zn 241- 0.31, Ag 0.54-0.64, Mn 1072-0.34, As 45.4-0.34 and Cd 0.34-0.44. All of the three plant species have enrichment factors exceeding hyperaccumulating criterion >1 for most of the elements investigated. Most of the hyperaccumulator values belong to Verbascum cheiranthifolium Boiss. Hyperaccumulating properties have been considered for reclamation of contaminated lands. This study claims that plants with high metal intake abilities escalate mobility of metals and increase contaminations on surface and subsurface.
The heavy metals Cd, Pb, Zn, Ni and Mo were determined in 27 samples of medicinal herbs taken from various places in Bielsko Biała and the neighbouring area. Samples were digested by the wet method in a microwave oven. Flame AAS and differential pulse polarography (anodic and stripping voltammetry) were used for determination of these metals. Oriental tobacco (CTA-ATL-1) as the certified reference material was applied for calibration and validation of analytical procedures.
The 15 - cm layer of bottom sediments of the Lake Bukowo was examined. Organic sediments make up to 32% of the Lake Bukowo bottom surface, the mixed sediments - 52% and the sandy ones - 16%. Bottom sediments of this lake displayed a high content of organic matter ca. 28%, nitrogen ca. l. 2%, silica 65% and phosphorus 0.9%. Nitrogen and phosphorus were deposit into sediments in the main form of organic compounds. These sediments were characterized by low content of metals (average: Ca 1%, Mg 0.8 %, Fe 1.3% and Al 1.1%). The pollution of Lake Bukowo increased comparison to 1987.
In order to evaluate a potential threat to soil environment by heavy metals, it is important to separate and determine their fractions by means of sequential extraction. The research aimed at evaluating the total content of lead and chromium as well as their fractions in soils localized on a moraine slope in the Siedlce Heights (transects A and B). Sequential fractionation of these elements was carried out according to Zeien and Brümmer’s method. Chemical analyses revealed varied contents of seven lead and chromium fractions in the soils. The largest amounts of both heavy metals were mostly recorded in the residual fraction (F7), and those of lead also in the organic fraction (F4). The least lead was found in the exchangeable fraction (F2) (it was not detected in easily soluble fraction F1), while the least chromium appeared in the easily soluble (F1) and organic fractions (F4). Statistical processing revealed that the examined lead and chromium fractions generally depended on separated fractions, total contents of these metals, and some properties of analyzed soils.
