For the purposes of this Issue Paper, metals most commonly found at Superfund sites will be discussed in terms of the processes affecting their behavior in soils, as well as in those of the laboratory methods available to evaluate this behavior. The retention capacity of soil will also be discussed with regard to the movement of metals between the other environmental compartments: ground water, surface water, or the atmosphere. Long-term changes in soil environmental conditions, due to the effects of remediation systems or to natural weathering processes, are also explained with respect to the enhanced mobility of metals in soils.

Research conducted in many research centers all over the world indicate health threats resulting from the presence of lead in the blood gradually decreases to the permissible amount. Lead accumulation in a living organism results in adverse changes in different body systems, symptoms of which include various behavioral changes. They can be reflected in grades obtained by the child at school. The aim of this paper was to establish whether the blood lead level diversify the boys in the respect of their school performance during consecutive years of primary education. The amount of lead in blood of 94 boys at the age of 10 has been measured; subsequently, the group of subjects was divided into two subgroups; the first one (termed in this paper „L”) comprised students whose Pb-B level was lower than 6 μg/dl (4,846 μg/dl on average) and the second one (termed „H”) comprised boys whose blood level exceeded 6 μg/dl (9,256 μg/dl on average). Academic performance in the arts, scientific subjects, geography and natural science in respective groups was assessed. Said procedure was replicated in respective subgroups after a year when the subjects were 11 years old. It was ascertained that the academic performance of the boys with higher blood lead levels deteriorated in scientific subjects and tended to worsen also in other school subject groups. Performance of the students whose blood lead level was lower in the initial examination remained unchanged or improved.

Badania podejmowane w wielu ośrodkach naukowych na całym świecie, wskazujące na zagrożenia zdrowotne wynikające z obecności ołowiu we krwi, zaowocowały stopniowym obniżeniem dopuszczalnej zawartości tego metalu ciężkiego w organizmie. Konsekwencją jego kumulacji są bowiem niekorzystne zmiany obserwowane w układach wewnętrznych, których jednym z przejawów są m.in. różnego rodzaju zmiany behawioralne. Mogą one przekładać się na oceny uzyskiwane przez dziecko w szkole. Celem niniejszej pracy było określenie czy poziom ołowiu we krwi różnicuje chłopców pod kątem ich osiągnięć szkolnych w kolejnych latach kształcenia w szkole podstawowej. Wykonano pomiar zawartości ołowiu we krwi 94 chłopców 10-letnich, a następnie całą grupę badanych podzielono na dwie podgrupy; pierwszą (zwana umownie „N”), w której znaleźli się uczniowie, których poziom Pb-B był mniejszy niż 6 μg/dl (średnio 4,84 μg/dl) i drugą (W) o zawartości ołowiu we krwi przekraczającej ten poziom (średnio 9,25 􀀀g/dl). Wgrupach tych oceniono osiągnięcia w nauce z przedmiotów humanistycznych, ścisłych oraz geograficzno-przyrodniczych. Procedurę tę w wyodrębnionych podgrupach powtórzono w kolejnym roku, a więc wśród 11-latków, Wśród chłopców o wyższej zawartości ołowiu we krwi stwierdzono istotne obniżenie się wyników w nauce przedmiotów ścisłych oraz tendencję do obniżania się ocen z pozostałych grup przedmiotów. Uczniowie, których poziom ołowiu we krwi był niższy w badaniu wyjściowym utrzymali lub podnieśli poziom swoich osiągnięć szkolnych.

Introduction and Aim. Breast milk is the first nourishment in the infancy period containing environmentally present chemical compounds. Literature data on the presence of heavy metals in mothers’ milk is insufficient. The study is to determine the influence of environmental factors on the content of heavy metals in breast milk. Material and Methods. This paper presents results of an investigation on the occurrence of heavy metals in breast milk. Absorption spectrometry technique using VARIAN Techtron Instrument type 5DA determined the content of Cu, Cd, Pb, Zn, Ni, Mn, Fe. The mothers were 16 to 40 years old and lived at least 5 years in the industrial region (Upper Silesia and Częstochowa, Cieszyn – Poland). Results. The co-occurrence of metals in the milk and the change of heavy metals concentration depends on the lactation time. Smoking and air pollution are important factors which influence the content of heavy metals in breast milk. Conclusions. Breast milk for infants is an important source of nourishment containing heavy metals.

In this work we compared the effect of five heavy metals: Zn, Pb, Cd, Ni and Cu on phospholipid composition of the ubiquitous soil fungus Paecilomyces marquandii, originating from a strongly metal polluted area and characterized by high tolerance to these elements. Cd, Ni and Cu caused an increase in phosphatidylcholine (PC). Only Pb decreased PC content, which was accompanied by a significant rise in the phosphatidic acids (PA) level, probably due to activation of phospholipase D which hydrolyzes PC to PA. This could result in membrane fluidity disturbance, and thus affect its integrity. The assessment of propidium iodide influx showed strong disturbance of membrane integrity for Cu and Pb stressed mycelia, whereas mycelia treated with Ni were impermeable to this dye. The results obtained revealed a strong Cu and Pb toxicity involving disruption of membrane integrity. Pb action was reflected by lipid composition, whereas changes in Cu treated mycelia did not completely elucidate its harmful effect on the membrane, which was most probably caused by Cu induced lipid peroxidation. Zn did not induce quantitative changes in PC and phosphatidylethanolamine (PE) but caused changes in phospholipid lipid saturation, which appears to be important for fungus adaptation to the presence of metals. The enhanced PC content balanced by higher PC saturation can help in the maintenance of proper membrane fluidity and result in alleviating the Cd and Ni induced stress. These results will allow to clarify the mechanism of Pb toxicity and help to elucidate the cellular basis of fungal membrane adaptation to heavy metals.

The biosorption of Pb(II), Zn(II) and Ni(II) from industrial wastewater using Stenotrophomonas maltophilia and Bacillus subtilis was investigated under various experimental conditions regarding pH, metal concentration and contact time. The optimum pH values for the biosorption of the three metals were in the range 5.0-6.0, while the optimal contact time for the two bacterial species was 30 min. Experimental data was analyzed using Langmuir and Freundlich isotherms; the former had a better fit for the biosorption of Pb(II), Zn(II) and Ni(II). The maximum adsorption uptakes (qmax) of the three metals calculated from the Langmuir biosorption equation for S. maltophilia were 133.3, 47.8 and 54.3 for Pb(II), Zn(II) and Ni(II), respectively, and for B. subtilis were 166.7, 49.7 and 57.8 mg/g, respectively. B. subtilis biomass was more favorable for the biosorption of Pb (II) and Ni (II), while S. maltophilia was more useful for the biosorption of Zn (II).

Agricultural usability of urban and industrial wastes was investigated in 2004 - 2006 in a pot experiment carried out in the vegetation hall. In the first year of the experiment maize was the test plant, oat grass in the second and oat in the third. The experimental design comprised 11 treatments differing with fertilizer and the kind of the supplied fertilizer components. The experiment used: mineral salts, farmyard manure, compost, municipal sewage sludge and industrial sewage sludge in two fertilizer doses. Metal concentrations in the test plants were diminishing in the following direction: oat grass < maize < oat. The lowest concentrations of the analyzed heavy metals were assessed in the plants fertilized with farmyard manure and compost (Zn, Cu). Among the tested plants the highest quantities of Zn, Cu, Ni, Pb and Cd were removed with the yield of the oat grass, then maize and oat. The highest uptake of Zn, Cu, Ni and Pb by plants was registered on a double dose of industrial sludge and Cd on a single dose of municipal sludge.

The presence of the single metals (Cd, Pb, Cu, Zn) induces ROS (reactive oxygen species) production and causes oxidative stress in plants. While applied in two-element combinations, trace metals impact organisms in a more complex way. To assess the resultant effect we treated the pea grown hydroponically with the trace metals in variants: CuPb, CuCd, CuZn, PbCd, ZnPb, ZnCd in concentrations of 25 µM for each metal ion. Abiotic stress inhibited root elongation growth, decreased biomass production, induced changes in root colour and morphology. It changed rate of ROS production, malondialdehyde content, increased activity and altered gene expression of defence enzymes (superoxide dysmutase, catalase, ascorbate peroxidase, glutathione reductase, γ-glutamylcysteine synthetase).

Heavy metals and antibiotics resistance are intense public interest owing to their pollution in the environment and potential deleterious effects on human health. A total of 15 isolates of Bacillus subtilis, Bacillus cereus, Pseudomonas aeruginosa and Escherichia coli (50 manure garden soils) were tested for their resistance against certain heavy metals and antibiotics. Minimum inhibitory concentrations of Pb²⁺, Co²⁺, Cu²⁺, and Zn²⁺ for each isolate were also determined. B. subtilis, B. cereus, P. aeruginosa and E. coli exhibited high tolerance to minimum inhibitory concentrations of 3,200 μg/ml for Pb²⁺, 400 μg/ml for Cu²⁺ and Co²⁺, and 100 μg/ml for Zn²⁺ in agar plates. All the isolates were highly resistant to lead and they showed 100% growth in 3,200 μg/ml concentration. It was observed that all isolates were resistant to a wide range of antibiotics namely clindamycin, ceftazidime, aztreonam and vancomycin.

The results of the research studies concerning the binding of heavy metals (HMs) by quartz sand functionalized with amino silanes have been described. The studies have been carried out on soils sampled from the areas affected by emissions from Copper Smelter and Refinery. The research aims to increase the food safety in the areas of industrial impact. The presence of polyamine chain in the hybrid materials obtained enables a binding of heavy metals (nickel, copper, cobalt). The best results are observed for the hybrid material having four amine groups (four coordination centers) per molecule. For this material the highest content after two extraction cycles (pH 7.0 and 5.0) is observed for copper (98.2%), but for other ions (nickel, cobalt) it is at least 85% of the initial amount of components available for plants.

Concentrations of several heavy metals in soil, water and grape samples (variety Plovdina) collected at five locations at different distances from the road in Southeast Serbia were determined using the Flame Atomic Absorption Spectrophotometry. There was a decrease in analyzed samples with an increase in distance from the road. A complete absence of several examined, very harmful heavy metals (Mn, Ni, and Cd) in all analyzed samples was found. The analysis of grape samples proved the presence of iron, zinc and copper in concentration ranges 3.3-19.8, 0.31-0.63, and 3.4-13.6 μg g-1, respectively. The content of heavy metals in soil, water and grapes were below allowable limits. Correlation analysis showed a significant relationship between the concentrations of metals in soil and grape samples.

The results of the research studies concerning binding of heavy metals and arsenic (HM+As), occurring in soils affected by emissions from Głogów Copper Smelter and Refinery, by silane nanomaterial have been described. The content of heavy metals and arsenic was determined by AAS and the effectiveness of heavy metals and arsenic binding by 3-Aminopropyltrimethoxysilane was examined. The total leaching level of impurities in those fractions was 73.26% Cu, 74.7% – Pb, 79.5% Zn, 65.81% – Cd and 55.55% As. The studies demonstrated that the total binding of heavy metals and arsenic with nanomaterial in all fractions was about as follows: 20.5% Cu, 9.5% Pb, 7.1% Zn, 25.3% Cd and 10.89% As. The results presented how the safety of food can be cultivated around industrial area, as the currently used soil stabilization technique of HM by soil pH does not guarantee their stable blocking in a sorptive complex.

The biomass of Curvularia lunata, used previously for hydrocortisone production, was investigated as a heavy metal biosorbent. Removal of lead, zinc and cadmium ions was evaluated as a function of biosorbent dosages, initial ion concentrations, mode of mycelium modifications, initial pH of metal solutions and when these metals ions where presented in binary as well in ternary combinations. The results presented in this paper indicate the potential utility of C. lunata waste biomass for lead and, to a lower extent, for zinc and cadmium ions removal from acid solutions.

From among various industrial contaminants which can pollute agricultural environment, heavy metals having the capacity of bioaccumulation deserve special attention. The total composition analysis of the heavy metals content in the polluted soils does not provide enough data about their accessibility to the crops cultivated on these soils. It is very important to have the information about the forms in which the examined element exists, because it decides about its mobility and toxicity for the environment. Using the sequential chemical extraction method of Zeien and Brümmer the fractions of Cu, Pb, Zn, Cd and As in the soils influenced by emissions from the Copper Smelter GŁOGÓW, were investigated. The aim of these investigations was to determine the availability assessment of the mentioned elements to the crops cultivated in this region.

Heavy metals determination in manures provides beneficial information to predict the availability and the potential contamination of environment. Therefore, a study was carried out to investigate heavy metals changes in livestock manure during a co-composting process. The metals were stepwise fractionated into exchangeable, adsorbed, organically bound, carbonate precipitated and residual forms by extracting with 0.5M KNO3, de-ionized water, 0.5M NaOH, 0.05M Na2EDTA and 4M HNO3, respectively. During the extraction process, the amount of metals remained highly dependent on an extraction method and stage of manure composting. Extractions released heavy metals contents in the final composted manure as Zn > Cu > Pb > Cr > Ni > Cd. Irrespective of the days of composting, extracting agents differed in the order HNO3 > Na2EDTA > NaOH > KNO3 > H2O for all heavy metals. Higher concentrations of heavy metals were observed during the early stages of composting. Conversely, there was a progressive increase in the concentrations of K, Ca and Mg during composting of manure. Total C in the manure reduced with composting days.

The pot experiment was set up with the split plot method in three repetitions in 2006. The objects of the first factor were the doses of manure and organic fertilizers to the soil in conversion to the brought in nitrogen (85 and 170 kg N·ha-1), the objects of the second factor were the types of fertilizers: manure, sewage sludge and the composts prepared from sewage sludge. The soil used in an experiment was supplied from The Agricultural Experimental Station in Lipnik. The soil was taken from the arable layer, it has the granulometric composition of the light loamy sand.The content of available phosphorus, potassium and magnesium formed on medium level, the pHKCl of the soil amounted to 5.13. The soil was characterized by 00 contamination of trace elements, which means that it contained the natural content of cadmium, copper, nickel, lead and zinc. Spring rape var. Licosmos was the test plant.The aim of the research was the assessment of the influence of manure, sewage sludge and compost prepared from sewage sludge on yield quantity of seeds and straw and the content of cadmium, nickel, lead and zinc in spring rape.The conducted research shows that fertilizers brought into the soil (manure, sewage sludge and compost prepared from sewage sludge) as well as two levels of fertilizing had a significant influence on the yield of the seeds and straw of spring rape. Manure, sewage sludge and compost prepared from sewage sludge played less significant influence on the decreasing or excessive increasing of heavy metals concentration in the seeds of spring rape. The double dose of fertilizers caused higher accumulation of heavy metals in the test plant. The straw of spring rape should be treated as a source of organic matter and the main nutrients for the soil. The highest concentration of copper, manganese, nickel and zinc in the straw of spring rape was noticed after the application of sewage sludge and of cadmium and lead after the application of compost prepared from sewage sludge.

A single-factor field experiment was carried out at the Cultivar Evaluation Station in Szczecin-Dąbie in 2008-2010. In the experiment, the compost produced with municipal sewage sludge by the GWDA method and high-calcium brown coal ash (furnace waste) were used. The perennial energy crop was a test plant - Virginia fanpetals (Sida hermaphrodita Rusby). It results from the carried out study that Virginia fanpetals biomass contained on average the most manganese (24.7 mg∙kg-1 d.m.), lead (2.50 mg∙kg-1 d.m.) and zinc (50.5 mg∙kg-1 d.m.) in 2008, while the most cadmium (0.33 mg∙kg-1 d.m.), copper (3.78 mg∙kg-1 d.m.) and nickel (2.57 mg∙kg-1 d.m.) in 2010. Average cadmium, copper, manganese, nickel, lead and zinc contents in test plant biomass were higher, respectively by 14.3%, 10.0%, 7.3%, 19.3%, 29.1% and 6.9%, in the objects where municipal sewage sludge compost had been applied without and with addition of high-calcium brown coal ash when compared to those where only calcium carbonate or high-calcium brown coal ash had been introduced into the soil. The differences in cadmium, copper, manganese, nickel, lead and zinc contents in Virginia fanpetals biomass between particular experimental objects were not signifi cant. The least zinc was absorbed by the test plant biomass in the object with high-calcium brown coal ash being applied in the fi rst year of study and annually. When evaluating the dynamics of heavy metals uptake, it was found to be the lowest in the fi rst year of study (ranging from 4.40% to 11.0%). It increased in the second and the third year of study, oscillating between 29.9% and 65.7%. The degree of heavy metals accumulation in Virginia fanpetals biomass differed, depending on the fertilisation applied. The bioaccumulation factor of cadmium, copper and nickel after three study years was average, while that of manganese, lead and zinc was intense.
