The uptake of trace elements by wild herbaceous plants in a multiple trace element-contaminated site was investigated. The bioaccumulation factor (BF) of trace elements was markedly variable among the different plant species. On average, the BF for various trace elements was in the following decreasing order: Zn > Cu > Mn > Ni > As > Pb > Cr. The translocation factor among the investigated plant species was also considerably variable and showed the following decreasing order: Mn > Zn > Ni > Cu > Cr > As > Pb. Several hyperaccumulating plants were identified: Artemisia vulgaris for As, Mn and Zn, Phalaris arundinacea for Mn and Ni, Heracleum sphondylium for Cr and Zn, and Bistorta officinalis for Mn and Zn. The marked accumulation of trace elements in the plant tissue suggests that the site may not be suitable for urban agricultural production. The plant tissue-borne trace elements could affect microbial activities and consequently interfere with the ecosystem functioning in the affected areas.

Phytomanagement of trace element-contaminated soils combines sustainable soil remediation with the use of plant biomass for different applications. Consequently, phytostabilization using plant species useful for bioenergy production has recently received increasing attention. However, the water requirement of most of these species is a limitation for their use under Mediterranean climatic conditions. In this work, eight plant species growing naturally in mine soils contaminated by trace elements were evaluated for their use as bioenergy crops using thermochemical (combustion) and biochemical (anaerobic digestion) methods. The higher heating values of the biomass of the plants studied were all within a narrow range (16.03–18.75 MJ kg−1), while their biochemical methane potentials ranged from 86.0 to 227.4 mL CH4 (g VS)−1. The anaerobic degradation was not influenced by the presence of trace elements in the plants, but the mineral content (mainly Na) negatively affected the potential thermal energy released by combustion (HHV). The highest annual energy yields from biogas or combustion could be obtained by the cultivation of Phragmites australis and Arundo donax, followed by Piptatherum miliaceum. Both options can be considered to be suitable final destinations for the biomass obtained in the phytostabilization of trace element-contaminated soils and may contribute to the implementation of these remediation techniques in Mediterranean areas.

Abstract Shooting range soil contamination with heavy metals is a common problem around the world. Usually, lead is the main contaminant in the shooting ranges. Extreme concentrations of trace elements create a toxic living environment for various plants. The purpose of this study was to evaluate the effect on lettuce (Lactuca sativa L.) grown in contaminated shooting range soil. The results showed that physiological parameters root elongation, shoot length and fresh biomass per plant was negatively affected, especially in the most contaminated site of the shooting range. At the most contaminated shooting range site shoots accumulated higher concentrations of Ni and Zn, roots – Cu, Ni, and Zn. The roots of plants grown in the most contaminated soil accumulated significantly higher concentrations of Cu, Ni and Sb in comparison with control (p < 0.05). Accumulation of Cu, Fe, Mn, Ni, Sb and Zn in the roots of the plants grown in the most contaminated site was higher compared to shoots (p < 0.05). Bioaccumulation factor of lettuce was lower than 1, only BF of Cu and Ni in plants from most contaminated site was significantly higher compared to control. In terms of translocation factor, the TFsoil to root of Cu and Pb among all plants and Ni in plants grown in the most contaminated site above 1 shows that metals absorbed by L.sativa were accumulated in root and lower metal translocation in shoots was determined, except for Mn.

Fertilizers, along with atmospheric deposition, are believed to contribute more than all other factors to the trace element burden of cultivated soils. This review will discuss trace elements in commercial fertilizer in relation to their transfer to soil–plant systems. Also, background levels in soils and the concentrations of trace elements in soils, phosphate rocks, and commercial fertilizers will be presented. Results from several short and long-term experiments indicated that the application of phosphate fertilizers to agricultural soils generally resulted in an increase of trace elements in soils and that the increase was most pronounced for Cd. The corresponding increase in plants was quite variable, ranging from no increase at all to a significant increase. The concentration of trace elements in plant species also showed a wide variation. The distribution and partitioning of trace elements among chemical associations in soils varied considerably for different elements. The highest percentage of Cd in soils, as estimated by sequential extraction, was associated with exchangeable fractions (25–41%), but the highest fraction of Zn (47%) was associated with resistant minerals. Uptake of trace elements by plants and solubility and mobility of these elements in the soil were affected to a greater extent by the plant species grown and soil pH, organic matter, and soil texture. Soil pH showed a significant but inverse relationship with the concentrations of most of the trace elements in plants. The addition of organic matter generally immobilized the trace elements in soils and caused reduction in plant uptake of most elements. A considerable proportion (up to 50%) of the total uptake of trace elements, and especially of Cd, was a result of atmospheric deposition. Ecological implications of contaminants in fertilizers and the resultant need for research are described.Key words: accumulation in soils, fertilizers, plant availability, soil properties, trace elements.

The present work investigates the uptake of selected trace elements (Cu, Sb, As, Pb, Cd, Zn, Cr, Mn, Ni, V, and Co) from soil and their accumulation in the biomass samples (leaves and flowers) of three selected native plants (namely Oenothera picensis, OP; Sphaeralcea velutina, SV; and Argemone subfusiformis, AS) around an industrial area (Puchuncaví-Ventanas) located in the Puchuncaví valley, in the central region of Chile. Primary emission sources in the area come from a copper refinery, coal-fired power plants, and a set of 14 other different industrial facilities. Trace element measurements in the native plants of this area and the ability to transfer of these pollutants from soil to plants (transfer factor) have been assessed in order to identify the potential use of these plant species for phytoremediation. Preliminary results showed a high concentration of trace elements in the OP, SV, and AS samples. The concentration of these elements in the plants was found to be inversely correlated to the distance of the primary emission sources. Moreover, the high concentrations of trace elements such as Cu, As, Cr and V, upon the toxic limits in the native plant species, suggest the need for continuous monitoring of the region. The OP species was identified as the plant with the highest capacity for trace elements accumulation, which also showed higher accumulation potential in whole aerial parts than in leaves. Transfer factor values suggested that these native plants had phytoremediation potential for the elements Cu, Pb, As, Ni, and Cr. This study provides preliminary baseline information on the trace element compositions of important native plants and soil in the Puchuncaví-Ventanas area for phytoremediation purposes.

The concentration of trace elements (Fe, Mn, Cr, Co, Ni, Cu, Pb, Cd, As) through the planktonic food chain of the White Sea have been studied by the experimental approach. The experiment included zooplankton sampled in a reference area feeding on a seston contained the different trace metals concentrations. Seston sampled in the st. Chupa was enriched by Fe, Cu, Pb, Cr, Co, As, and Ni comparing to the seston from st. Kartesh (reference area). The differences in the concentrations of the suspended particular matter and of the indicator elements of a terrigenous admixture (Al, Ti, Zr) evidence on higher natural background of the trace metals’ content in the seston from st. Chupa due to higher contribution of the minerals. Zooplankton that fed on the seston characterised by higher trace elements’ content has accumulated Fe, Mn, and Cr, at a less degree, Ni, Co, Pb, and Cu; particularly, these were the elements which content were high in seston. Despite Mn content in seston did not differ between two treatments, this element was accumulated by the zooplankton, but had low content in faecal pellets. This tells about the highest Mn assimilation by the zooplankton; this element may become the most bioavailability. When comparing the trace element content between the seston and the faecal pellets, the concentrations of the most elements in faecal pellets are lower comprising as low as Zn – 72%; Mn – 24; Cu – 97; Pb – 62; Cr – 99; Co – 78; Ni – 87; As – 96; Cd – 65% of the concentration in the seston.

Oats followed by alfalfa was grown in the greenhouse on three soil types which were limed at three levels and received treatments of 20, 40, 60 and 100 pounds of B; 4, 16 and 64 ounces of Mo; 20 and 60 pounds per acre of S. Yield and growth characteristics of the plants were recorded, content of B, Mo, S, Co and Zn in plant tissue was determined. Oats was much more sensitive to excessive amounts of B than was alfalfa. The yield of oats on unlimed and on soil limed to pH of 6.2 decreased consistently with increasing rates of B. At the highest liming rate a decrease in yield resulted with a B application of 40 pounds or more per acre. Sixty pounds per acre of B did not reduce the yield of alfalfa but there was a significant reduction in yield at 100 pounds per acre. Toxic effects, as indicated by chlorosis of the leaves, was much more marked at the low pH levels. Effects of pH level on uptake of the trace elements and effect of Mo and S on B uptake are shown and discussed.

The main objective of this study was to evaluate the contamination by mercury (Hg), methylmercury (Me-Hg), cadmium (Cd), selenium (Se), zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn) in dolphins stranded on the French Mediterranean coast. The distributions of these contaminants in the organs of dolphins have also been studied. Overall, contamination levels varied according to the following sequence: liver > kidney > lung > muscle, except for cadmium (kidney > liver > lung > muscle). Size and sex of animals were also considered. Young dolphins were less impacted with trace elements than adults, except for copper. Among the studied parameters, the most important appeared to be the size of mammals. In addition, in the case of mercury and selenium, the sex of mammals seemed to be also relevant. The correlations between the concentrations of trace elements suggest the existence of detoxification processes. Since 1990s, using dolphins for tracing marine pollution, a slight reduction in the burden of the considered trace elements could be noted.

AbstractTo assess trace element concentrations (Zn, Cu, Pb, Cr, Cd and Ni) in the mangrove swamps along the Saudi coast of the Arabian Gulf, thirteen samples of surface sediment and leaves of grey mangrove, Avicennia marina were collected and analyzed. The detected trace element contents (μg g-1) in surface sediments were in the following descending order according to their mean values; Cr (49.18) > Zn (48.48) > Cu (43.06) > Pb (26.61) > Ni (22.88) > Cd (3.21). The results showed that the average concentrations of Cd and Pb exceeded their world average concentration of shale. The geo-accumulation, potential ecological risk and toxicity response indices demonstrated that trace elements have posed a considerable ecological risk, especially Cd. The inter-relationships between physico-chemical characters and trace elements suggests that grained particles of mud represent a noteworthy character in the distribution of trace elements compared to organic materials. Moreover, the results revealed that Zn was clearly bioaccumulated in leaf tissues A. marina. Dredging, landfilling, sewage effluents and oil pollution can be the paramount sources of pollution in the area under investigation.

The use of plant species to stabilize and accumulate trace elements in contaminated soils is considered of great usefulness given the difficulty of decontaminating large areas subjected to mining for long periods. In this work, the bioaccumulation of trace elements is studied by relating the concentrations in leaves and roots of three plants of Mediterranean distribution (Dittrichia viscosa, Cistus salviifolius, Euphorbia pithyusa subsp. cupanii) with the concentrations of trace elements in contaminated and uncontaminated soils. Furthermore, in the case of D. viscosa, to know the concentration of each element by biomass, the pool of trace elements was determined both in the aerial part and in the roots. The bioaccumulation factor was not high enough in any of the species studied to be considered as phytoextractors. However, species like the ones studied in this work that live on soils with a wide range of concentration of trace elements and that develop a considerable biomass could be considered for stabilization of contaminated soils. The plant species studied in this work are good candidates for gentle-remediation options in the polluted Mediterranean.
