    Opis:
    Despite recording the worst heavy metal disaster involving children, there is still scarcity of information on risk assessment of playground soils in Nigeria. In this study, thirty-six soil samples at 0-5 cm depth were collected from nine playgrounds in Owerri metropolis during the dry and rainy seasons. Five heavy metals were fractionated into six chemical fractions using a modified sequential extraction scheme and mean concentrations quantified by AAnalyst 400 Perkin Elmer AAS. Predictive risk models were used to obtain information about the risk of metals contamination to children using these playgrounds for longer periods. These reveal that there were no significant differences in the mean values of bioconcentration factors of all five metals in the various playgrounds for the two years of data. Even though risk values for both dry and rainy season followed the same trend, it was observed that the Zinc showed highest bioconcentration factors (1.6), average daily dose (230.08 mg/kg/day) and risk (5095593 mg/kg/6years). Over all, playgrounds UPS, TSO and SCP had highest mean risk values, respectively. Though with no clear trend, mobility factors showed a weak and positive correlation with risk. Children in playgrounds of public schools within Owerri metropolis could, therefore, be at risk of Mn, Cu and Zn toxicity problems as projected risk values were high for all studied playgrounds. This assessment could help identify playgrounds with urgent need for heavy metals reduction goals, consequently contributing to preserving children’s health.

    Opis:
    The performance of electrically stimulated phytoremediation in the removal of lead, cadmium and copper was assessed in this study. A combination of phyto and electro remediation was attempted in this study for the remediation of the metals from water. Three tanks were setup with different operating conditions for this experiment: control A (only phytoremediation system), control B (only electro remediation) and treatment (combination of phyto and electro remediation). The electrically enhanced phytoremediation system and electro remediation system were operated 2h/day at voltages of 4V for 25 days continuously. In this experiment, the Eichhornia crassipes, an able phytoremediator exhibited efficient and fast removal of heavy metals from synthetic solution in electro assisted phytoremediation system. The electrically enhanced phytoremediation using aluminum sheet electrodes showed better and effective removal of Cd, Pb and Cu than aluminum rod electrodes. A more favorable and moderate increase of pH was noticed in electrically stimulated phytoremediation system. Eichhornia crassipes has tremendous potential to reduce maximum amount of cadmium (within 15 days), lead (within 15 days) and copper (within 10 days) under electrically stimulated condition. Under electrified condition, maximum amount of Cd and Cu was accumulated in the aerial parts of Eichhornia crassipes but maximum concentration of Pb was attained by roots. This indicates the high heavy metal accumulation capacity of Eichhornia crassipes under electrified conditions. The results showed that 4V voltage is probably suitable to stimulate the Eichhornia crassipes to synthesize more chlorophyll and voltage can improve growth and ability to resist adverse circumstances by promoting chlorophyll synthesis. Eichhornia crassipes stimulated by an electric field has grown better and assimilated more metal. Bioconcentration factor (BCF) an index of hyperaccumulation, indicates that electrically stimulated Eichhornia crassipes is a good hyper accumulator of Cd (BCF = 1118.18) and Cu (BCF = 1152.47) and a moderate accumulator of Pb (BCF = 932.26). Translocation ability (TA) ratio indicates that Eichhornia crassipes have the ability to translocate more amounts of Pb, Cd and Cu to its upper portion under electrified condition. The results imply that the electro-phytoremediation technique seems to be promising in the treatment of wastewater contaminated with heavy metals.

    Opis:
    The study was conducted in July - August 2018 with the aim of analyzing the concentration of lead heavy metals (Pb) in water, sediment and macrozoobenthos in the Karangsong waters area, Indramayu Regency. The research method used is a survey method with purposive sampling technique that is the determination of location based on the existence of certain objectives and in accordance with various considerations, then observed the content of lead metal (Pb) in the Central Laboratory of Padjadjaran University. The research was conducted in situ and exsitu. Parameters of insitu research include temperature, pH and DO carried out in Karangsong waters, Indramayu Regency. Exsitu research parameters include testing of lead metal (Pb) on water, sediment and macrozoobenthos conducted at the Central Laboratory of Padjadjaran University. The results showed that the Pb concentration in the Karangsong waters had exceeded the threshold, which ranged between 1,05 – 1,33 mg/l, while the Pb concentration in sediment was higher than the Pb concentration in water. Lead metal in sediment has not exceeded the threshold. The ability of macrozoobenthos to accumulate lead metal in water and sediment (Bioconcentration Factor / BCF) is included in the low accumulative category because BCF is less than 100.

    Opis:
    Agricultural soils that have been irrigated with the contaminated water from metallurgical mining activities for more than 70 years constitute an environmental problem as well as a concern for food security and human health. The presence of lead in the soil and cultivated pastures is highly dangerous, due to its toxicity, persistence and accumulation in plants and animals (cattle). This element enters the trophic chain of humans due to the intake of meat, milk and its derivatives. The concentration of lead was determined in the soil and the cultivated pastures with Lolium x hybridum Hausskn and Medicago sativa L. The soil and pastures samples collected from plots irrigated with river water contaminated with heavy metals at a depth of 0-20 cm. The content of Pb determined by the atomic absorption spectrophotometry. The results showed the lead concentrations in soil in the range of environmental quality standards for soils according to Peruvian regulations. In the soil with L. x hybridum and M. sativa the average content of lead was 57.17 ± 6.29 mg.kg-1 and 57.19 ± 8.99 mg.kg-1; in the above-ground tissues were 1.17 ± 0.69 mg.kg-1 and 1.62 ± 0.68 mg.kg-1, respectively. In addition, no significant differences were observed in the Pb content in the soil and plant tissues. The bioconcentration factor (BCF) in the above-ground tissues of L. x hybridum and M. sativa was less than one and they were not significant. Therefore, irrigation with long-term contaminated water is not a concern for the farmers in the Mantaro Valley.

    Opis:
    Oil and gas production water (PW) is brought to the surface when hydrocarbon reservoirs deep within geologic strata are extracted. Large volumes of PW present environmental challenges when released to the land surface due to high levels of salinity and potentially toxic elements. The effects of PW on soil chemical properties and plant response were investigated in both growth chamber and field studies. In the growth chamber, wheat (Triticum aestivum) and red clover (Trifolium repens) were grown in soil which was flooded with synthetic PW. The PW was enriched with several metals (Na, Cu, Cr, Pb) and had an acidic pH (2.5) and EC of 33,650 dSm-1. Soil amendments included food waste compost, composted biosolids, gypsum (CaSO4) and NPK 10-10-10 fertilizer. Metal concentrations in soil and plants were determined using flame atomic absorption spectrophotometry. The food waste compost provided for maximal uptake by clover of Cu, Cr and Pb compared to all other amendments. In several soil treatments both wheat and clover behaved as metal hyperaccumulators having high bioconcentration factors (BCF, ratio of metal concentrations of plant tissue to soil). Clover was the most efficient in accumulating Cu and Cr in shoots (BCF = 22.2 and 30.6, respectively). Greatest metal uptake in both plant species occurred in either the biosolids or compost treatment. In a field study, plots were flooded with synthetic PW and grown to corn (Zea mays) and a turf mixture (Kentucky bluegrass, Poa pratensis and perennial ryegrass, Lolium perenne). Both corn and turf accumulated substantial soil Cu and Pb. Corn experienced significant die-off; however, turf survived the PW application. Turf mixtures, clover and/or wheat may be suitable for phytoremediation of PW-affected soil. Addition of organic amendments to soil may enhance metal uptake by plants.

    Opis:
    Lead (Pb) is a heavy metal often discovered to be polluting the water areas. One of the efforts made to overcome the heavy metal pollution in estuaries was phytoremediation technique using mangroves. The Wonorejo River was one of the rivers that received industrial waste loads. There were various types of mangrove plant species at the estuary of the Wonorejo River. The location of this research was divided into 3 monitoring stations (A, B, C). Station A was directly adjacent to the estuary, as location C was farther away and very close to the sea. However, station B was located between location A and B. This study aimed to determine the ability of mangrove in remediating and illustrating the distribution of Pb, at the Wonorejo River estuary. Moreover, it also aimed to determine the values of Bioconcentration (BCF) and Translocation (TF) Factors in the ability of Avicennia alba, Avicennia marina, Sonneratia caseolaris, Avicennia lanata, and Rhizophora stylosa to accumulate Pb. The samples were the roots, stems, and leaves of mangroves, with the water and sediment at the Wonorejo estuary, as all solid materials were also extracted. The samples were analyzed for heavy metal concentration, using an atomic absorption spectrophotometer (AAS). The results showed that the highest average Pb concentration for waters and sediments was obtained at station C and A, with values of 0.069 mg/L and 4.22 mg/kg, respectively. It was further observed that the Pb concentration in the water was lower than in sediment, indicating that the metal was accumulated in the sediments. On the basis of the BCF value, the most effective mangrove involved in the accumulation of Pb was A. alba. The highest values of TF for both root to stems and to leaves in the accumulation of Pb was also discovered in A. lanata and A. alba mangroves, respectively. On the basis of the Pb distribution mapping, the concentration of the metal was shown to increased, as the research location moved further away from the estuary. Conclusively, each type of mangrove had different ability to accumulate and translocate Pb in its body, with the potential of using those plants as phytoremediaton agents for the metal.

    The aim of the research was to compare the accumulative macro- and microelements in the shoots of Carex acutiformis, Carex echinata, Carex paniculata, Carex remota and Carex rostrata. The content of components in the shoots of the plants was analyzed in relation the chemical composition of the soil. The research was done within the area of four mid-forest spring niches situated in the valley of a tributary of the Słupia River located within the area of Leśny Dwór Forest Inspectorate (Northern Poland). The examined species of Carex, in comparison to other plants in spring niches, were characterized by an average capacity to accumulate both macro- and microelements, which results in little interest in these species when planning artificial buffer zones. Out of the analyzed species, the shoots of C. echinata accumulated the largest quantities of Mg, Zn and Mn, the shoots of C. paniculata –Fe, C. remota – K, Ni, Al and Sr, C. acutiformis – N and P, and the shoots of C. rostrata –Ca and Cu. Similarities between the species of Carex, which resulted from their accumulative properties, were discovered. C. echinata and C. rostrata were characterized by high levels of bioconcentration factors (BF) for Sr, Cu and Ca and low BF for K. C. paniculata and C. remota represented high BF levels for Ni and Mg and low BF levels for Sr, Al, Mn, Cu, Ca, Fe and N. On the other hand, C. acutiformis was characterized by high BF levels for P, K and Mn. In spite of an average accumulative capacity, the examined species of Carex were characterized by highly developed surface and underground zones which had effective impact on the retention of pollutants.

    Urbanization is the cause of many changes which are taking place in the environment, including those found in the catchment. With this in mind, it is an important issue to properly protect water reservoirs and also take action to counter the adverse effects of human activities on the natural environment, including water bodies. To address the increasing degradation of surface waters in the European Union, the approach to the evaluation and protection of water resources was changed. This approach was formulated in the European Union Water Framework Directive (2000/60/EC), which calls for the protection of water, as well as an environment-friendly and comprehensive approach to water assessment. Herein, the ecological status of surface waters and groundwater is assessed on the basis of the ecological potential of the biological, physico-chemical and hydromorphological indicators.

    The accumulation and translocation of trace metals in soil and in sugarcane crop irrigated with treated effluents from sugar industry compared to soil and sugarcane crop irrigated with bore-well water were determined. In the present study the impact of irrigation with treated effluent from the sugar industry on the trace metal contamination of sugarcane juice was assessed. It revealed that the mean concentrations of Cd, Pb, Cu, Mn and Zn in the soil of fields irrigated with effluent and in juice from sugarcane grown on such fields were higher than those from bore-well water irrigated fields. The concentrations of trace metals in treated effluent exceeded the permissible limits of the Indian standards (Central Pollution Control Board-2000). The concentrations of Cd, Pb, Cu and Zn in juice of sugarcane grown on fields irrigated with effluent also exceeded the permissible limits of Indian standards and WHO/FAO expert committee recommendations. Their concentrations in juice of sugarcane grown in fields irrigated with bore-well water were within the limits of safety, except for Cd. The transfer factor for Zn was considerably higher than those of the other trace metals. The metal concentrations of sugarcane juice showed significant correlations with those of soil, which was not the case when bore well water was used for irrigation.

    Opis:
    The purpose of the research was to determine the respective contents of heavy metals (Pb, Cd, Ni, Zn and Cu) in soil and extracted soil fauna in humid mixed coniferous forest (MHCF), fresh mixed coniferous forest (MFCF) and in fresh mixed forest (MFF) of Niepolomice Forest. The contents of heavy metals varied, depending on the forest type and trophic group. The highest values of cadmium, lead, and copper content were recorded in MFCF, while of nickel in MHCF. Analysis of variance and post-hoc Tuckey’s showed significant differences between the concentrations of Zn and other metals in invertebrates in different types of forest habitats. Bioconcentration factor shows that both soil saprophages and predacious invertebrates accumulated the largest amounts of Cd and smaller amounts of Zn, while the accumulation of remaining metals depended on the type of forest habitat. In fresh mixed coniferous forest predators accumulated heavy metals in the following order: Cd > Zn > Pb > Ni > Cu, in the case of saprohages it was: Cd > Zn > Ni > Cu > Pb.
    Celem badań było określenie zawartość metali ciężkich (Pb, Cd, Ni, Zn i Cu) w glebie i wyekstrahowanej faunie glebowej w trzech typach siedliskowych lasu w Puszczy Niepołomickiej – w lesie mieszanym wilgotnym, borze mieszanym świeżym i borze mieszanym wilgotnym. Zawartość metali ciężkich uzależniona była od typu lasu i grupy troficznej. Najwieksze wartości kadmu, ołowiu i miedzi odnotowano w glebie w borze mieszanym świeżym BMśw, a niklu w borze mieszanym wilgotnym BMw. Wskaźnik biokoncentracji wskazuje, że zarówno saprofagi i drapieżne bezkręgowce glebowe w największej ilości kumulowały Cd, w mniejszej Zn, natomiast pozostałe metale kumulowane były w zależności od typu siedliskowego lasu. W borze mieszanym świeżym drapieżne kumulowały metale w kolejności Cd > Zn > Pb > Ni > Cu, a saprofagi Cd > Zn > Ni > Cu > Pb.

    Opis:
    Accumulation and enrichment of heavy metals in the above ground parts of Australian native Acacia pycnantha (Ap) and Eucalyptus camaldulensis (Ec) growing in an abandoned copper mine located in Kapunda, South Australia have been studied. Cu and other metals (Na, Al, K, Ca, Fe, Zn, Cd and Pb) in plants and corresponding soils were analysed to evaluate plant interaction with soils containing heavy metals. As per the total metal analysis of leaf and corresponding soil samples, Ap accumulated 93.6 mg kgˉ¹ of Cu in leaf while the corresponding soil concentration was 1632 mg kgˉ¹. The Ec accumulated 5341 mg kgˉ¹ of Cu in leaf while the concentration of this heavy metal in soil was 65 mg kgˉ¹ in soil. The ESEM spectral analysis also showed a high leaf concentration of Cu in Ec (7%) as against only 0.12% in Ap. The average bioconcentration factor for Cu, Zn,Cd and Pb in Ec wasmuch higher than that of Ap. Similarly, enrichment factor was more in Ec for Cu, Zn and Pb than in Ap. In contrast, translocation factor for only Zn and Cd was high in Ap. This study points out that Ec and Ap have different stabilising potential in remediating heavy metals like Cu in mined soils.
