In recent years, the construction industry has struggled with a variety of issues such as material availability, supply channel management, and increasing cost materials. These have encouraged search for replacements substitutes existing Blast Furnace Slag is used in mineral amendment or aggregate. Their use Earth Construction, due to their post-industrial origin, may be associated increased le...

Mangrove wetlands serve as both a sink and source for arsenic (As), as mangrove plants are able to uptake and accumulate As. The present study used pot experiments to evaluate As accumulation and translocation in mangrove (Aegiceras corniculatum L.) seedlings grown in As contaminated soils. Results indicated that A. corniculatum seedlings grew normally under As stress with minute growth inhibit...

The ability of heavy metals bioaccumulation to cause toxicity in biological systems—human, animals, microorganisms and plants—is an important issue for environmental health and safety. Recent biotechnological approaches for bioremediation include biomineralization (mineral synthesis by living organisms or biomaterials), biosorption (dead microbial and renewable agricultural biomass), phytostabi...

This paper aims at providing a preliminary study of the effects of different doses of tannery waste containing high amounts of organic substances, mineral elements and heavy metals on growth dynamics and metal accumulation in willow plants. Scions of Salix alba L., clone S61-02, were grown in the open near Pisa (Italy), in pots filled with a natural soil. Willows were pruned for a unique shoot ...

Two species of Pb-adapted shrubs, Alyssum montanum and Daphne jasminea, were evaluated in vitro for their tolerance to elevated concentrations of cadmium. Shoot cultures were treated with 0.5, 2.5, and 5.0 μM CdCl2 for 16 weeks and analyzed for their organogenic response, biomass accretion, pigment content, and macronutrient status. Cadmium accumulation and its root-to-shoot translocation were ...

The objectives of the present field study were to examine the soil enzyme activities in the soil root zones of Plantago lanceolata and Plantago major in different heavy metal contaminated stands. Moreover, the investigations concerned the intensity of root endophytic colonization and metal bioaccumulation in roots and shoots. The investigated Plantago species exhibited an excluder strategy, acc...

The presence of Psidium guajava in polluted environments has been reported in recent studies, suggesting that this species has a high tolerance to the metal stress. The present study aims at a physiological characterization of P. guajava response to high nickel (Ni) concentrations in the root-zone. Three hydroponic experiments were carried out to characterize the effects of toxic Ni concentrati...

To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor (Ricinus communis L.) cultivars (Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment (0, 1 and 2mg/L Cd) and a pot experiment using Cd-contaminated soil (34mg/kg) with the addition of ethylenedinitrilotetraacetic acid (EDTA). The results indicated that there were significant dif...

The effects of copper (Cu) on the yield and Cu uptake of three ecotypes of Elsholtzia splendens and one of Elsholtzia argyi were studied using solution culture. Three Cu concentrations were compared: 0.31 (control), 50 and 100 micromol L(-1). Although E. argyi took up more Cu in the aboveground parts, typical visual symptoms of Cu toxicity appeared when the plants grew in 50 and 100 micromol Cu...

A novel, cost-effective and eco-friendly technologies are needed to remove Zinc from the contaminated soil environment. The present research study was designed to assess the naturally enhanced phytoextration and phytostabilization potential of different plant species from the Zinc (II) contaminated soil. Uptake of Zinc by plant species in a metal contaminated soil was studied in pot culture exp...
