Opis:
The research aimed to assess the effect of bottom sediment on the content, bioaccumulation and translocation of heavy metals in maize biomass. The investigations were conducted in 2006-2007 as a pot experiment on light soil of the granulometric composition of weakly-loamy sand. The experimental design comprised 3 treatments: without sediment (I), a 5% sediment admixture (II) and a 10% sediment admixture to the soil (III). Bottom sediment was added to the soil in the first year of the investigations. The content of Zn, Cu, Ni. Pb, Cd and Cr was determined using the ICP-EAS method in the plant material after its dry mineralization and ash solution in HNO3. The uptake of the above-mentioned metals by maize was computed alongside their bioaccumulation and translocation coefficients. The effect of bottom sediment admixture on heavy metal concentrations in maize was determined to be varied, e.g. a 5% dose of sediment added to soil decreased the content of all the analyzed heavy metals in the biomass of maize aerial parts, whereas a 10% admixture increased the content of Cu, Ni, Pb and Cr. The values of bioaccumulation coefficients revealed that an admixture of both doses of bottom sediment led to a decreased accumulation of Zn, Cu, Cd, Cr and Ni (5% dose) in maize aerial biomass. Moreover, the plant more easily accumulated Zn, Cd and Cu than Cr, Ni or Pb. Permissible amounts of heavy metals in plants to be used as animal fodder were not exceeded in the maize biomass.
Celem badań była ocena wpływu osadu dennego na zawartość, bioakumulację i translokację metali ciężkich w biomasie kukurydzy. Badania prowadzono w latach 2006-2007, w warunkach doświadczenia wazonowego, na glebie lekkiej o składzie granulometrycznym piasku słabogliniastego. Schemat doświadczenia obejmował 3 obiekty: bez osadu (I), z dodatkiem 5% osadu (II) i dodatkiem 10% osadu do gleby (III). Osad denny dodano do gleby w pierwszym roku badań. Zawartość Zn, Cu, Ni, Pb, Cd, Cr w materiale roślinnym oznaczono po suchej mineralizacji i roztworzeniu popiołu w HNO3. Obliczono wynos ww. metali przez kukurydzę oraz ich współczynniki bioakumulacji i translokacji. Stwierdzono niejednoznaczny wpływ dodatku osadu dennego na zawartość metali ciężkich w kukurydzy. Osad dodany w ilości 5% do gleby wpłynął na zmniejszenie zawartości wszystkich analizowanych metali w nadziemnej biomasie kukurydzy, natomiast 10% dodatek osadu na zwiększenie ich zawartości (Cu, Ni, Pb, Cr). Wartości współczynników bioakumulacji świadczą, że dodatek osadu dennego w obu dawkach spowodował zmniejszenie akumulacji Zn, Cu, Cd, Cr oraz Ni (dawka 5%) w biomasie nadziemnej kukurydzy, ponadto rośliny łatwiej akumulowały Zn, Cd i Cu niż Cr, Ni i Pb. W biomasie kukurydzy nie stwierdzono przekroczenia dopuszczalnych zawartości metali ciężkich przyjętych do oceny roślin pod względem ich przydatności paszowej.

Opis:
The importance of nickel (Ni) in the environment is an issue that is gaining broader recognition. While nickel is an element essential for plants, it is also a heavy metal. Nickel is a component of nine metalloenzymes, including urease, which participates in urea hydrolysis. It also helps some plants to protect themselves against pathogens and herbivorous insects. There are many sources of Ni in the environment, which can be a problem because at higher concentrations this element is toxic to plants and other living organisms. Therefore, standards have been defined for the Ni content in air, water, soil and plants. Its content is monitored in the air. More and more frequently, attention is paid to this element as an allergen in humans. In the world, attempts have been made to phytoextract nickel from contaminated soils using nickelphilous plants, the so-called hyperaccumulators, and even to recover the metal from these plants by so-called phytomining. On the other hand, nickel-containing fertilizers are marketed and used in cases of nickel deficiency in plants. In industry, this element is primarily used for the production of steel and alloys. The most recent application of nickel is related to graphene, which was invented 10 years ago. Although nickel contamination does not occur in Poland, we cannot rule out this risk in the future. Thus, it is important to monitor the fate of nickel in the environment.

Opis:
Zinc (Zn) is an important element for the proper plant growth and development. However, Zn is also a metal commonly used in the industry, which may cause its excessive accumulation in soil. High soil Zn content leads to its increased uptake by plants growing near industrialized areas. Arbuscular mycorrhizal fungi (AMF) live in symbiosis with the majority of plant species. These fungi have the ability to reduce Zn uptake by plants, when this element is present in an increased concentration in the plant root zone. An experiment was carried out to determine the effect of AMF on Zn uptake by lettuce plants grown in rockwool at increasing levels of Zn in the nutrient solution. This effect was investigated at two P levels in the nutrient solution, i.e. 40 mg P (optimal for lettuce) and 10 mg P dm-3. Mycorrhizal parameters, yield, content of dry matter, ascorbic acid, glucose, fructose and sucrose as well as the plant’s nutritional status in P, Cu, Mn, Mo, Fe and Zn were determined in the study. The effectiveness of mycorrhization of lettuce grown in rockwool was proven in the study. AMF reduced the Zn content in lettuce grown under excessive Zn concentrations in the root zone. Moreover, this decrease was greater in plants receiving the nutrient solution with a lower concentration of P. Additionally, mycorrhiza decreased the content of Cu, Fe, Mn and Mo in lettuce, despite an optimal (not increased) concentration of these micronutrients in the nutrient solution supplied to plants. Arbuscular mycorrhiza did not affect the plant yield, content of ascorbic acid, glucose, fructose, sucrose or the content of P in lettuce leaves.

Opis:
The progressive degradation of soils is a recently increasing environmental problem. The risk of soil degradation may be associated, for example, with landslides, flooding, soil erosion. However, these are relatively rare phenomena compared to the risk of chemical degradation caused by human activity. Given the limited research on the positive effect of miscanthus biochar on soil properties, a study was carried out aimed at determining changes in pH, electrical conductivity, sorption properties, and mobility of selected heavy metals in sandy soil treated with various chemicals. Biochar used in the study was produced at a temperature of 300°C. The addition of biochar to soil generally increased the pH value, regardless of the type of chemical degradation. The study revealed a decrease in the hydrolytic acidity value and, at the same time, no significant changes in the content of alkaline cations and sorption capacity of the biochar-treated soil. The best effect on reducing the mobility of trace elements was achieved by adding biochar to the soil supplemented with acidifying substances. Bearing in mind the current agricultural and environmental problems, there is a need to increase the effectiveness of biochar and to direct its action to improve specific soil properties.

Opis:
Our objective has been to determine the total content of magnesium, iron, chromium and zinc, as well as the heavy metal fractions in selected natural fertilisers, such as swine and bovine manure and poultry litter from laying hens and broilers. The total content of the metals was determined by the ICP-AES method following dry mineralisation in a muffle furnace at 450°C and dissolving the ash in HCl (1:1). Fractions of Fe, Zn and Cr were isolated by the 3-step sequential fractionation method proposed by the Community Bureau of Reference (BCR). This study has shown that the analysed organic materials had different content of the determined metals. The largest amount of Mg was found in litter from laying hens and the largest amounts of Fe, Cr and Zn were in litter from broiler chickens. The smallest amount of Mg was found in swine manure, Fe and Cr were the least abundant in litter from laying hens, and the lowest Zn content was in bovine manure. The content of these four heavy metals was significantly differentiated by the origin of fertiliser. The exchangeable fraction F1 had the smallest share in the total Fe content among all the fertilisers. As for chromium, this fraction made the smallest contribution to the total Cr content in litter from laying hens and broilers while the reducible fraction F2 was the smallest part of the total content in both types of manure. Fraction F1 of zinc was the smallest in the total content in swine and bovine manure and while the oxidisable fraction F3 made up the smallest share in the total content of this metal in litter from broilers.

Opis:
Lead has been used extensively for thousands of years. Once introduced into the environment, like any other heavy metal, lead accumulates in soil and sediments. High lead concentrations in river and lake sediments can be harmful to aquatic organisms. At present, uncontaminated water sediments in the northern and central parts of Poland contain below 9 mg of lead per kg. The lakes located within the following lake districts: Greater Poland, Pomeranian and Masurian, provided 409 samples of surface sediments from deep spots (the profundal zone). All the samples were tested for the content of Pb and other selected macroelements. The content of Ca, Mg, Fe, K, Mn, Na, P, Pb and S was determined by ICP-OES and the total organic carbon (TOC) was evaluated by the coulometric titration method. The observed range of lead concentration was from below 3 to 222 mg kg-1. The average content was 37 mg kg-1, the geometric mean 30 mg kg-1, and the median 33 mg kg-1. In the majority of samples, the lead concentration was higher than the geochemical background. Only in 5.77% of the samples, the lead content was lower than 10 mg kg-1. The lead concentration in the sediments was relatively well correlated with the total organic carbon (r = 0.59), aluminium (r = 0.45) and sulphur (r = 0.47), moderately correlated with iron (r = 0.26) and potassium (r = 0.28), very weakly correlated with phosphorus (r = 0.12) and negatively correlated with the calcium concentration (r = -0.28). No correlation was observed for manganese (r = -0.05), magnesium (r = 0.07) and sodium (r = -0.07). Factor analysis revealed the presence of two factors that together accounted for nearly 45% of variation. The first factor included aluminium, potassium and magnesium, and the second one - sulphur and organic carbon. The lead share was low in the first factor (0.343), but very high in the second factor (0.757). Based on the results of the factor analysis, it can be assumed that lead in the organic matter-rich sediments of the profundal zone is deposited mainly in the form of sulphides. Lead concentration varied among the sediments obtained from various lake districts; it was lower in the lakes located within the Pomeranian Lake District than in those from Greater Poland and Masurian Lakes.
Ołów jest wykorzystywany powszechnie od tysięcy lat. Uruchomiony do środowiska, podobnie jak inne metale ciężkie, podlega akumulacji w glebach i osadach wodnych. W osadach rzecznych i jeziornych duża zawartość Pb może szkodliwie oddziaływać na organizmy wodne. We współczesnych niezanieczyszczonych osadach wodnych na obszarze północnej i środkowej części Polski zawartość ołowiu wynosi poniżej 9 mg kg-1. Z jezior Pojezierzy: Wielkopolskiego, Pomorskiego i Mazurskiego pobrano 409 próbek powierzchniowych osadów z głęboczków jezior (strefa profundalna). We wszystkich próbkach określono zawartość Pb oraz wybranych pierwiastków głównych. Zawartość Ca, Mg, Fe, K, Mn, Na, P, Pb i S określono metodą ICP-OES, a zawartość węgla organicznego (TOC) – metodą kulometrycznego miareczkowania. Stężenie ołowiu wynosiło od <3 do 222 mg kg-1, średnia zawartość – 37 mg kg-1, średnia geometryczna – 30 mg kg-1, a mediana – 33 mg kg-1. W większości zbadanych próbek zawartość ołowiu była podwyższona w stosunku do wartości tła geochemicznego. Jedynie w 5,77% próbek zawartość ołowiu była niższa niż 10 mg kg-1. Stężenie ołowiu w osadach wykazuje stosunkowo wysoką korelację z zawartością węgla organicznego (r = 0,59), glinu (r = 0,45) i siarki (r = 0,47), słabą – ze stężeniem żelaza (r = 0,26) i potasu (r = 0,28), bardzo słabą – ze stężeniem fosforu (r = 0,12), ujemną – z zawartością wapnia (r = -0,28) oraz brak korelacji ze stężeniem manganu (r = -0,05), magnezu (r = 0,07) i sodu (r = -0,07). Analiza czynnikowa wykazała obecność 2 czynników, które łącznie wyjaśniają blisko 45% zmienności. Pierwszy czynnik grupuje glin, potas i magnez, drugi – siarkę i węgiel organiczny. Udział ołowiu w czynniku pierwszym jest niski (0,343), a w drugim – bardzo wysoki – 0,757. Na podstawie wyników analizy czynnikowej można przyjąć, że w bogatych w materię organiczną osadach strefy profundalnej jezior ołów występuje przede wszystkim w formie siarczków. Zaobserwowano zróżnicowanie w zawartości ołowiu w osadach różnych pojezierzy; osady jezior Pojezierza Pomorskiego zawierają mniej Pb niż osady jezior Pojezierzy Wielkopolskiego i Mazurskiego.

Opis:
Chemical composition of composts depends on a number of factors, including a type of composted waste and composting technology. This study was conducted to determine concentrations of carbon, nitrogen and selected heavy metals in composts manufactured from various waste substances and using different technologies. Organic carbon content in the composts depended on a type of composted waste - the smallest quantities were found in the compost of municipal waste. Organic matter transformations occurring during composting probably led to a systematic decline of the soluble organic compound amounts. The share of soluble carbon in the total concentration did not exceed 35% of the analysed composts. The composts based on plant waste were more abundant in nitrogen and the share of nitrogen extracted with sodium pyrophosphate and sodium base did not exceed 40%. Analysis of fractional composition of humus compounds of the composts revealed higher content of humic acid carbon in relation to fulvic acid carbon. The proportion of non-hydrolysing carbon in these materials was on average over 70%. The content of the most mobile heavy metal forms in the composts was low and implied that these elements occurred in a form less available to plants.
Skład chemiczny kompostów zależy m.in. od rodzaju kompostowanych odpadów, ale może być także uwarunkowany technologią kompostowania. Dlatego celem podjętych badań było określenie zawartości węgla, azotu oraz wybranych metali ciężkich w kompostach produkowanych z różnych substancji odpadowych i według różnych technologii. Zawartość węgla organicznego w kompostach zależała od rodzaju kompostowanego odpadu - najmniej tego składnika stwierdzono w kompoście z odpadów komunalnych. Przemiany materii organicznej zachodzące podczas kompostowania prowadziły do systematycznego zmniejszania się ilości rozpuszczalnych związków organicznych. W badanych kompostach udział węgla rozpuszczalnego w zawartości ogólnej nie przekraczał 35%. Zasobniejsze w azot były komposty z odpadów roślinnych, a udział azotu wyekstrahowanego pirofosforanem sodu i zasadą sodową nie przekraczał 40%. Analiza składu frakcyjnego związków próchnicznych badanych kompostów wykazała, w każdym przypadku, większą zawartość węgla kwasów huminowych w stosunku do zawartości węgla kwasów fulwowych. Udział węgla niehydrolizującego w tych materiałach wynosił średnio ponad 70%. Zawartość najbardziej mobilnych form metali ciężkich w kompostach była niewielka, co wskazuje na występowanie tych pierwiastków w postaci związków trudniej dostępnych dla roślin.

Opis:
The impact of adding a natural clay sorbent such as halloysite on the content of selected heavy metals in the biomass of common orchardgrass (Dactylis glomerata L.) was studied in a pot experiment. The study was conducted on mucky soil enriched anthropogenically with heavy metals, whose values exceeded permissible standards of soil quality and values of the geological background. The experiment included three variants with differentiated percentage of halloysite, i.e. 10%, 30% and 50%, as well as two control cultivations. The results confirm the impact of halloysite on the physicochemical properties of soil, consisting in increased soil pH and sorption capacity. Addition of halloysite to soil also differentiated the quantity of crop yield and concentration of heavy metals in the plant and soil. Halloysite was found to have an inconsistent impact on the concentration of heavy metals in the biomass of common orchardgrass, which was proven by some elevation in the level of heavy metals and a higher bioaccumulation factor (BAF). Halloysite constituting 50% of the mass of substrate substantially increased the consumption of Pb and reduced the sorption of Cr. Addition of halloysite stabilised Zn and Cu in soil. The results of our preliminary investigation indicate that addition of halloysite to soils with excessive concentrations of heavy metals influences the level of soil sorption to the extent which may be effective for soil remediation.

Opis:
The Arctic region is under an ever-increasing anthropogenic influence. The nature in the Arctic is extremely vulnerable to the effects of pollutants, which may eventually lead to certain irreversible ecological processes. Heavy metals occupy a special place among priority pollutants. Therefore, the aim of this study has been to assess the ecological status and the degree of contamination with heavy metals of the soils of Arctic and sub-Arctic areas. Arctic soils were studied in the region of the White Sea and the Barents Sea during the Arctic Floating University, a research expedition held in July 2012 by M. Lomonosov Northern (Arctic) Federal University. During the expedition, samples were collected and the landscapes (topography, vegetation) were described. In order to assess the impact of environmental contamination, the total content of heavy metals in soils was evaluated by X-ray fluorescence analysis (XRF). The level of soil contamination was assessed according to the maximum permissible concentrations ( MPC), temporary permissible concentrations (TPC), chemical substance factor (Kc) and the total pollution index (Zc). Our analysis of the experimental data showed a wide-range change in the soil agrochemical parameters. It has been demonstrated that the investigated soils of the Arctic and sub-Arctic areas represent different soil properties, are affected by different climatic conditions and belong to different texture taxonomic classes, e.g. the grain-size distribution varies from sand to clay loam; the pH ranges from strongly acid to neutral and the content of organic substances can be very low to high. According to the total pollution index, almost all the soils present an acceptable heavy metal contamination level. In most of the studied soils, the heavy metals in terms of amounts accumulated can be ordered as follows: Co > Pb > Cu > Zn > As > Ni > V > Mn.

Opis:
The safety and security of different foodstuffs are considered important and have a high priority in global sustainable development. The contents of Fe, Mn, Cu, Zn, Ni, Pb and Cd were estimated in edible parts of 60 vegetable samples, irrigation water and agricultural soil collected from 5 farms in suburban areas around Riyadh district, Saudi Arabia. Also, soil pollution indices, pollution load index and contamination factor (PLI, CF), bioaccumulation factor (BAF), non-carcinogenic and carcinogenic risk indices (HQ, THQ, and ILCR) were estimated. The content of heavy metals in irrigation water and soil was within the recommended permissible levels, except for Cd in soil, which exceeds permissible levels. The trend of metal concentrations in both agricultural soil and vegetables was found in the order: Fe > Mn > Zn > Cu > Ni > Pb > Cd. Cluster analysis of the metal content in vegetables showed a tendency towards the accumulation of heavy metals in the order of leaves > roots > fruits > flowers > tuber. The BAFs values found were < 1.0, HQs values for Fe, Mn, Cu, Zn and Ni were found to be < 1, while the estimated HQs for Pb and Cd were > 1, posing greater risk to the health of adults and children. THQ values were higher for children compared to adults. ILCR values for Cd showed a serious issue, as it exceeds the threshold risk limit (>10−4) in all parts of the investigated vegetables in all sampling sites.

Opis:
The aim of this study has been to determine the influence of sewage sludge on the content of selected trace elements in Virginia mallow and in the soil after harvesting these plants. Sewage sludge was the source of nitrogen and phosphorus for the plants, while potassium was supplied in the form of mineral fertilisers. Virginia mallow plants grown without fertilisation served as the contnrol. The form and dose of sewage sludge did not have any larger effect on the concentrations of copper and zinc in the plants. The content of manganese and chromium increased as the the dose of either form of sewage sludge increased. In turn, the content of nickel in Virginia mallow tended to decrease as the doses of sludge rose. The biomass of Virginia mallow contained significantly more cadmium when fertilised with sewage sludge. Significantly more Mn and Pb accumulated in the soil which had been enriched with wet sewage sludge, while the soil treated with pelleted sewage sludge contained more Cd. The soil content of Zn, Mn, Pb and Cr tended to increase as the dose of sewage sludge increased. With respect to nickel and cadmium, their soil content was significantly differentiated by the applied doses of sewage sludge but the direction of these modifications was inconsistent. The forms or doses of sewage sludge applied left the content of copper in soil unaffected. Concerning the accumulation in the aerial parts of Virginia mallow plants, the heavy metals can be ordered as follows: Cd < Cu < Cr < Ni < Zn < Mn. Generally, sewage sludge applied in doses that covered the demand of Virginia mallow for nitrogen and phosphorus did not cause excessive increase in the content of heavy metals in the crop’s aerial biomass. However, an increase in the dose of sewage sludge tended to raise the content of mobile forms of heavy metals in soil after harvest of Virginia mallow.

Opis:
Metale ciężkie, w tym także cynk, gdy dostaną się do gleby w nadmiernych ilościach, stanowią dość trwałe zanieczyszczenie, w przeciwieństwie do różnego rodzaju zanieczyszczeń organicznych, podatnych w większym lub mniejszym stopniu na degradację mikrobiologiczną. Mimo iż akumulacja metali ciężkich przez drobnoustroje jest procesem powszechnym, to nie do końca poznanym. Granice tolerancji nie są jednakowe i zależą od ich bioróżnorodności i czasu trwania imisji, a także właściwości fizykochemicznych gleby, jej struktury, zawartości materii organicznej, pH i pojemności kompleksu sorpcyjnego. Coraz częściej do oceny stanu zanieczyszczenia gleby wykorzystuje się metody biologiczne, w tym aktywność enzymów glebowych, i w nich należy upatrywać szybkiej diagnozy jakości gleb. Wskaźniki te mogą być jednak wykorzystywane tylko do oceny gleb zanieczyszczonych metalami ciężkimi, a są mało przydatne w ocenie jakości gleb zanieczyszczonych związkami organicznymi.
Heavy metals, e.g. zinc, present in soil in excessive quantities become quite persistent contaminants. Thus, they differ from organic pollutants, which can be degraded, to a various degree, by microorganisms. Although the accumulation of heavy metals by microorganisms is widespread, this phenomenon has not been thoroughly investigated. Tolerance limits are not uniform and depend on the biodiversity and duration of ambient concentration, as well as on the physicochemical properties of soil, soil structure, organic matter content, pH and sorptive complex capacity. Soil contamination is more and more frequently assessed with biological methods, by testing for example the activity of soil enzymes. Such assays, however, can be used to evaluate the quality of soils contaminated with heavy metals, but are less useful for testing soils polluted with organic compounds.

Opis:
Migration and concentration of heavy metals in infiltration waters within unsaturated and saturated zones of a carbonate massif result from their mobility as well as anthropopression. The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn.
