“…The total soil sample (about 300 kg) was transported to the laboratory and subsequently used to prepare the pot experiment with M. jalapa. The soil was characterised by physical and chemical analysis according to the Italian Official Methods of soil chemical analysis (Ministry of Agricultural, Food and Forestry Policies 1999) for its heavy metal concentration by following previously described procedures for rhizosphere and leaf analysis (Papa et al 2010;Bartoli et al 2012). The analyses were repeated three times.…”

“…The Cd, Cr, Cu, Pb and Ni concentrations were measured via graphite furnace AAS, and the Zn concentration was measured by flame AAS. Accuracy was examined by concurrent analysis of standard reference materials by the Resource Technology Corporation (Laramie, WY, USA); the recovery ranged from 90 % to 100 % for each element (Papa et al 2010;Bartoli et al 2012). The analyses were performed three times.…”

Some Pseudomonas fluorescens strains, consistently isolated from the rhizosphere of wild plants grown in a soil that was highly polluted with illegal waste of smelter residues, were utilised for Mirabilis jalapa seed bioinoculation to verify their effects on seed germination and on promoting a higher heavy metal accumulation in the plant rhizosphere and/or uptake in the leaves. The high content of heavy metals in the soil induced a decrease in either the leaf dry weight or photosynthetic pigment concentration during all vegetative phase of M. jalapa. Bioinoculation with P. fluorescens strains significantly increased the germination of seeds and the root length in the contaminated soil. In some bacterial strain/seed combination, bioinoculation significantly increased the accumulation of heavy metals in M. jalapa rhizosphere. For Cd, the concentration of this metal in the rhizospheres of bioinoculated plants ranged from 270 to 910 μg g −1 of dry weight compared with 200 μg g −1 of dry weight for the non-coated plants. Two P. fluorescens strains, AA27 and MO49, which were isolated from Artemisia annua and Melilotus officinalis, respectively, induced a significantly higher rhizosphere availability also for Cr, Cu, Ni and Zn. However, despite the relevant accumulation of the heavy metals in the plant rhizosphere, generally the metal uptake into the leaves was rather low. Both analysis of variance and principal component analysis confirmed this finding. However, one P. fluorescens strain, CD1, which was isolated from the multi-metal accumulator Cynodon dactylon, significantly promoted the M. jalapa leaf uptake for Cr, Cu and Zn. The plant metal uptake assessment, confirmed the per se capability of M. jalapa to effectively uptake Cd (30 %) and Cu (12.72 %) from the rhizosphere to the leaves, whereas the uptake for the other metals was low: Ni (2.66 %), Zn (2.46 %), Cr (1.75 %), Pb (0.73 %).

Geochemical and Ecotoxicological Evaluation of an Estuarine Sediment Section at Pacoti River/Ce, Brazil

Pacoti estuary is located on the East coast of Ceará State/Brazil and is influenced by several sources of pollution. The sediment quality in three sampling stations was evaluated through an integrated approach. The sediments obtained were analyzed geochemically with respect to texture, organic matter, phosphorus, nitrogen and concentration of metals (Fe, Pb, Cu and Zn). Additionally, the metal loading in the sediment was determined considering a toxic risk quotient (RQ) and enrichment factor (EF). The ecotoxicological approach consisted of acute and chronic toxicity tests with species of marine invertebrates. The geochemical and ecotoxicological data were integrated using qualitative and technical criteria for multivariate analysis. The analyses showed a moderate change in the quality of the sediment Pacoti and there are influences of different contaminant sources. For this reason, one cannot disregard the input of other contaminants, not measured in this study, which probably may also have been relevant for sediment toxicity. Nonetheless, the data suggest that Pb and Cu metals as well as N tended to quality degradation in depositional areas and the sediment had some influence on the biological effects observed. KEYWORDS:

“…Heavy metals are among the most toxic environmental pollutants, and they pose a particular threat for soils which are the main reservoirs for contamination (Boros et al 2011, Trevisan et al 2012. Heavy metal pollution contributes to gradual degradation of the soil environment in many parts of the world (Bartoli et al 2012); it may lead to permanent soil damage, loss of soil fertility and depletion of plant cover (Wyszkowska et al 2009, Boros et al 2011, Bartoli et al 2012. Heavy metals have adverse effects on the biological properties of soil, such as enzymatic activity and microbial counts (Mikanova et al 2001, Mertens et al 2007, Wyszkowska et al 2008, and plants (Ciećko et al 2001, Wyszkowska et al 2007, Bartoli et al 2012, Hejcman et al 2012).…”

This study evaluates the effectiveness of organic fertilizers in restoring the homeostasis of soils contaminated with zinc. The activity of selected enzymes participating in the transformation of carbon, nitrogen, phosphorus and sulfur and the sensitivity of white mustard plants to zinc were analyzed. A greenhouse pot experiment was carried out. Uncontaminated soil served as control. Six organic substances which potentially neutralize the adverse effects of zinc were used: tree bark, finely ground barley straw, pine sawdust, cattle manure, compost and cellulose. It was found that in less contaminated soil (300 mg Zn 2+ /kg), all of the analyzed organic substances minimized zinc adverse effects on the biochemical properties of soil, including the activity of dehydrogenases, catalase, urease, acid phosphatase, alkaline phosphatase, β-glucosidase and arylsulfatase. In more contaminated soil (600 mg Zn 2+ /kg), the negative consequences of zinc pollution were effectively mitigated only by cellulose, barley straw and manure. Cellulose had the highest soil restoration potential, as demonstrated by resistance indicator values for different enzymes. Cellulose, compost, manure and straw increased the resistance of white mustard plants to zinc, but only in treatments contaminated with 300 mg Zn 2+ /kg. Bark and sawdust potentiated zinc toxic effects on mustard plants.
