2001 Sep;22(5):108-11 In each site, we examined the effect of proximity to road on heavy metal concentrations (cadmium, nickel, lead, and zinc) in four of the most common roadside plant species—Melilotus indicus, Herschfeldia incana, Avena sativa, and Artemisia californica—as well as on soil metal concentrations. 3.2.2. Under Mn-toxicity, the majority of Mn in seedlings was retained in the roots; C. sinensis seedlings accumulated more Mn in roots and less Mn in shoots (leaves) than C. grandis ones and Mn concentration was lower in Mn-toxicity C. sinensis leaves compared to Mn-toxicity C. grandis ones. But, there are also studies on plant resistance mechanisms to protect plants against the toxic effects of heavy metals such as combining heavy metals by proteins and expressing of detoxifying enzyme and nucleic acid, these mechanisms are integrated to protect the plants against injury by heavy metals. Ecology 5 (2) 6-9 (In Chinese), Induced free radical peroxidation injury of plants by cadmium, Huang Y, Hong R (1997): Induced free radical peroxidation injury HMs at toxic levels have the capability to interact with several vital cellular biomolecules such as nuclear proteins and DNA, leading to excessive augmentation of reactive oxygen species (ROS). 2013 Mar;53:74-86. doi: 10.1016/j.envint.2012.12.009. This thesis aimed at evaluating the contamination of urban stormwater from an upstream watershed by micropollutants and their introduction pathways, and estimating the hydrological effects and the pollutant removal performances of Sustainable Urban Drainage Systems (SUDS). ultrastructure of nuclei and chloroplasts in somatic cells of Trapa The success of phytoextraction depends upon the identification of suitable plant species that hyperaccumulate heavy metals and produce large amounts of biomass using established agricultural techniques. Rajkumar M, Prasad MN, Swaminathan S, Freitas H. Environ Int. Epub 2018 Oct 19. Environmental pollution from hazardous waste materials, organic pollutants and heavy metals, has adversely affected the natural ecosystem to the detriment of man. These suggested that the PvSR2 is a specific heavy metal responsive gene and might play an important role in resistance to the damage caused by heavy metals. with English abstract), Influence of heavy metals on the activity of Spirodela polyrrhiza catalase (CAT), Dong H (1999): Influence of heavy metals on the activity of Environmental Science and Pollution Research, Ameliorative effect of exogenously applied oxalic acid on nickel (heavy metal) induced stress in Zea mays, Mercury Stress Resistances in Nauclea Orientalis Seedlings Inoculated with Arbuscular Mycorrhizal Fungi, Heavy Metals Contents of PM10 in Ambient Air of Ahvaz City, Iran, The evaluation of heavy metals concentration related to PM 10 in ambient air of Ahvaz city, Iran, Cadmium sorption by Moringa stenopetala and Moringa oleifera seed powders: Batch, time, temperature, pH and adsorption isotherm studies, Soilless Culture - Use of Substrates for the Production of Quality Horticultural Crops, Influence of Soilless Culture Substrate on Improvement of Yield and Produce Quality of Horticultural Crops, Effect of Oil Palm Frond Compost Amended Coconut Coir Dust Soilless Growing Media on Growth and Yield of Cauliflower, Micropollutant fluxes in urban runoff : effects of sustainable urban drainage systems, The Evaluation of Heavy Metals Concentration Related to PM10 in Ambient Air of Ahvaz City, Iran, Performance of engineered soil and trees in a parking lot bioswale, Photosynthetic performance and anti-oxidative response of Cornus controversa seedlings under cadmium and lead stress, Phytoremediation of Industrial and Pharmaceutical Pollutants, Application of a mixture of fly ash and topsoil for rehabilitation in open-pit coal mines in South East Asian countries, Performance of Two Bioswales on Urban Runoff Management, Effects of road proximity on heavy metal concentrations in soils and common roadside plants in Southern California.

Case studies are presented where phytoremediation has been or can be successfully applied in Alpine areas to: (1) clean-up industrial wastewater containing sulphonated aromatic xenobiotics released by dye and textile industries; (2) remediate agricultural soils polluted by petroleum hydrocarbons; (3) improve food chain safety in soils contaminated with toxic trace elements (As, Co, Cr and Pb); and (4) treat soils impacted by modern agricultural activities with a special emphasis on phosphate fertilisation. Metallothionein (MT) is a cysteine rich protein related to heavy metal sequestering in animal and fungal cell systems. However, on the other hand, micronutrients and heavy metals are a group of nonbiodegradable elements with the tendency of bioaccumulation in living systems (Mocquot et al., 1996;Krishnamurti and Naidu, 2000; ... Les principales espèces utilisées sont des macrophytes de type roseau (Phragmites) et joncs (Typha, Juncus, Scirpus). The sequences of the cDNA inserts and homological analysis showed that both PvSR5 and PvSR51 encode a polyubiquitin respectively. USA.gov. The effects of the exogenous application of OA (1000 μM) on maize plants’ (Zea mays) growth parameters and superoxide dismutase (SOD; EC 1.15.1.1), catalase (CAT; EC 1.11.1.6), reduced glutathione (GSH) and lipid peroxide contents were evaluated in the presence or absence of nickel (Ni) induced stress. 2019 Apr;26(10):9851-9860. doi: 10.1007/s11356-018-04103-z. (2000): Accumulation and distribution of Cu and Zn in mycorrhizal Pinus sylvestris and its associated ectomycorrhizal fungus Suillus bovines exposed to elevated Although not a new concept, phytoremediation is currently being re-examined as an environmentally friendly, cost-effective means of reducing metal contaminated soil and other substrates throughout North America and Europe. Human hair samples were also analyzed to indicate the exposure level in the human body. Laboratory studies had demonstrated that "Merlin" could tolerate cadmium and copper up to 50 mg/L and 30 mg/L, respectively. (3): 71-76 (In Chinese with English abstract), Purifying of metal-binding proteins from roots of maize by HPLC anti-phase cartridges, He D, Luo J (1991): Purifying of metal-binding proteins from roots This study was aimed at investigating the potential of Moringa stenopetala and Moringa oleifera in the removal of cadmium(II) ions from water. Effects of heavy metals on plants result in growth inhibition, structure damage, a decline of physiological and biochemical activities as well as of the function of plants. The aim of this study was to inventory the types of plant growth-promoting rhizobacteria (PGPR) present in the rhizosphere of plants grown in soils contaminated with heavy metals, recalcitrant organics, petroleum sewage or salinity in China. All rights reserved. Some mechanisms of plant adaptation to metal stressors have been now decrypted. The urinary levels of Cd (U-Cd), β2-microglobulin (U-BMG), retinol binding protein (U-RBP), and N-acetyl-β-d-glucosaminidase (U-NAG) were measured. Furthermore, the peroxidase (GPX) activities were decreased after Cd treatment while elevated by Pb exposure in Cornus controvera seedlings. metal mobility of Pb/Zn tailings and the phyto-toxicity of A typical Cd-polluted area of South China was selected to determine the Cd exposure and related early renal effects of the general population, including children. Chinese Bulletin of Botany 7 (1) 34-39 (In Chinese These pollutants arise from anthropogenic sources as well as natural disasters such as hurricanes and volcanic eruptions. Goal, scope and background: Metal toxicity causes multiple direct and indirect effects in plants that concern practically all physiological functions.
