The heavy metals concentrations are vary in different days of a month. Airborne particulate matter along with volatile organic compounds, heavy metals, and other compounds have raised many concerns to many countries including Iran. (In Chinese), The primary studies on the effects of cadmium and lead on the photosynthesis of woody plants, Huang H, Zhang C (1986): The primary studies on the effects of Northern blot analysis revealed a low level of transcripts of polyubiquitin in unstressed bean leaves, but the gene expression was strongly stimulated by heavy metals, elevated temperature and salicylic acid, whereas wounding had almost no effect. Concerns about motor vehicle emissions on human health are typically focused on aerial pollution and are regulated via controls on tailpipe emissions. Microorganisms possess mechanisms that regulate metal ion accumulation to avoid heavy metal toxicity and there are many reports about microbial resistance to heavy metals [5-7]. Epub 2018 Oct 19. (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 Heavy metal pollution in the soil results in the accumulation of heavy metals in plants. The results showed that Arundo donax could survive in the wetland when the concentrations of Cu2+, Pb2+, Cd2+, Zn2+, Ni2+ and Hg2+, In this review, chemical and biological parameters are discussed that strongly influence the speciation of heavy metals, their availability to biological systems and, consequently, the possibilities to use bioremediation as a cleanup tool for heavy metal polluted sites. Advances in Biochemical Engineering/Biotechnology. Epub 2008 Aug 8. (1999): Effect of mercury and cadmium In addition, high concentrations of such metals affect on absorption and transport of essential elements, disrupt metabolism and have sever impacts on growth and reproduction ability, as well as causing diseases such as Saturnism, Mercurialism, Alzheimer's disease, carcinogenic and affect the central nervous system, kidney, bone, liver and skin. In this paper, it is hypothesized that probiotic microorganisms can also be used to decrease the xenobiotics intake in humans. THE EFFECTS OF HEAVY METALS ON PLANT PHOTOSYNTHESIS Many different studies indicated that HMs inhibit the net photosynthetic rate (Pn) and intracellular CO2 concentration [68,69]. To study the effects of heavy metals on plants and mechanisms of resistance, one must select crop cultivars and/or plants for removing heavy metals from soil and water. This is a clear indication that OA ameliorates heavy metal stress in maize via biochemical pathways in which it acts as an important chelator and detoxifier of nickel. There was a reduction in cadmium removal between 0 to 60°C for M. stenopetala and 0 -40°C for M. oleifera before increasing with subsequent temperature increases. Age at onset in carriers of parkin mutations varied as did the rate of progression of the disease: the younger the age at onset the slower the evolution. Patients with a single heterozygous mutation had significantly later and more asymmetrical onset and more frequent levodopa-induced fluctuations and dystonia than patients with two mutations. Salinity was found to have a positive effect on cadmium uptake by the plant and this may be related to a higher bioavailability of the metal in soil due to decreased Cd sorption on soil particles. With an initial cadmium concentration of 7 mg/l, M. stenopetala seed powder, at a dose of 2.50 g/100 ml, reduced the concentration of cadmium by 53.8%. Very little is known about manganese (Mn)-toxicity-responsive genes in citrus plants. The amount of topsoil was successfully increased by mixing FA in topsoil without soil erosion by rainfall (Gorman et al. This study was aimed at investigating the potential of Moringa stenopetala and Moringa oleifera in the removal of cadmium(II) ions from water. Results of the present study revealed that the concentrations of PM10 were higher than the reliable standards for the two studied seasons. This research report is about the potential of coconut coir dust (CD) amended with oil palm frond (OPF) compost soilless growing media for cauliflower cultivation. As metals cannot be broken down, when concentrations within the plant exceed optimal levels, they adversely affect the plant both directly and indirectly. Similarly, environmental Cd pollution increased NAG and BMG in the urine of adults. of Cd by rapeseed in wet soil. We evaluated the spatial distributions of personal exposure using indigenous exposure factors and field monitoring results of water, soil, food, and indoor and outdoor air samples. However, relatively little is known about the molecular bases of hyperaccumulation. Heavy metals (HMs) are described as elements with metallic properties having an atomic number higher than 20. tips of bean (Vicia faba). There were 50 storm events with a total precipitation of 563.8 mm during February 2007 and October 2008. Decrease in the bioavailability to farmlands would reduce the accumulation of heavy metals in food. To study the effects of heavy metals on plants and mechanisms of resistance, one must select crop cultivars and/or plants for removing heavy metals from soil and water. After eight years, tree growth characteristics were similar across both sites. Multivariate models showed that the urinary excretion of BMG, RBP, and NAG was positively associated with Cd levels in the urine of both children and adults. Ying yong sheng tai xue bao = The journal of applied ecology / Zhongguo sheng tai xue xue hui, Zhongguo ke xue yuan Shenyang ying yong sheng tai yan jiu suo zhu ban. Heavy metal toxicity, especially the toxicity of available Zn and Cd is the major constraint on plant colonization at Fankou Pb/Zn mine tailings. Chromium is known to be a toxic metal that can cause serve damage to plant. Metal toxicity causes multiple direct and indirect effects in plants that concern practically all physiological functions. Mycorrhizal symbiosis showed a significant effect of the resistance to Hg of N. orientalis plants grown in Hg-polluted and Hg-unpolluted media. Sinica 37 (1) 14-24 (In Chinese with English abstract), Effects of Pb 2+ , Cd 2+ , Hg 2+ on lacti-dehydrogenase (LDH) of Vicia faba L, Duan C, Wang H (1998): Effects of Pb 2+, Cd 2+, Hg 2+ on lacti-dehydrogenase (LDH) of Vicia faba L. Acta Ecologica Sinica 18 (4) Heavy metal pollution in soil and water is a global environmental concern. After forward stepwise multiple logistic regression analysis, dystonia at onset and brisk reflexes were not longer significantly different but were correlated with age at onset rather than the presence of the parkin mutation. Phytoextraction by halophytes is a promising alternative for the remediation of heavy metal contaminated sites affected by salinity since saline depressions often indicate sites of industrial effluents accumulation, contaminated by heavy metals, including Pb and Cd. Epub 2008 Dec 6. 1 (5) 85-88 (In Chinese with English abstract), Environmental sources of Pb and Cd and their toxicity to man and animals, Guo D (1994): Environmental sources of Pb and Cd and their toxicity to man and animals. The treatment CDC a provided optimum plant growth conditions of cauliflower throughout the growing period due to superiority in physiological traits (stomatal conductance, photosynthesis rate and chlorophyll content in leaves) and higher rate of nutrients uptake resulting maximum total dry mass production thereby economic yield i.e., production of biggest curd (302 g/plant). Our results indicate that strains from contaminated soils are similar to well-described PGPR found in agricultural soils worldwide. and yeasts (Saccharomyces sp.) (2000): Accumulation and distribution of Cu and Zn in mycorrhizal Pinus sylvestris and its associated ectomycorrhizal fungus Suillus bovines exposed to elevated Chinese with English abstract), Accumulation and distribution of Cu and Zn in mycorrhizal Pinus sylvestris and its associated ectomycorrhizal fungus Suillus bovines exposed to elevated Cu and Zn concentration in cultivating substrates, Huang Y, Tao S, Chen Y, et al. bicornis Osbeck. These suggested that polyubiquitin might play important roles in resistance to heavy metals and various environmental stresses. The characters of large biomass, exuberant root and good adaptability of Arundo donax suggested its great potential in remediation of polluted soils. However, Hg accumulation and its translocation to the leaves were very low, either in mycorrhizal or non-mycorrhizal seedlings. expression under heavy metal stress. Worlwide, including in Alpine areas, the controlled use of appropriate plants is destined to play a major role for remediation and restoration of polluted and degraded ecosystems, monitoring and assessment of environmental quality, prevention of landscape degradation and immobilisation of trace elements. Chinese Science 21 (5) When compared to the control, the treatment bioswale reduced surface runoff by 99.4%, and reduced nitrogen, phosphate, and total organic carbon loading by 99.1%, 99.5%, and 99.4%, respectively. Mott. artificially polluted with Cd was used for batch extraction tests. Heavy metal pollution in the soil results in the accumulation of heavy metals in plants. In particular, the influence of soil salinity in metal accumulation has been studied as there is notable evidence that salinity changes the bioavailability of metals in soil and is a key factor in the translocation of metals from roots to the aerial parts of the plant. This might be associated with more Mn accumulation in roots and less Mn accumulation in leaves of Mn-toxicity C. sinensis seedlings than those of C. grandis seedlings. On one hand, heavy metals show negative effects on plants. In this paper the research progress on the It is suggested that La3+ could be used to resist lead stress at the beginning under stress while the stress was not so serious. Correspondingly, the residents in V1 had higher Pb (8.14 mg/kg) levels in hair than those in the other two villages. The induction of the biological activities of metal transporters, such as metallothioneins (by scavenging reactive oxygen species [ROS]) and phytochelatins, under heavy metal stress imparts tolerance to crop plants, though the role of phytochelatins in minimizing the bioaccumulation of heavy metals in plants can also have adverse effects. 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. 2016. Acta Agriculture Boreli-Sinica 6 (3) 70-75 (In Chinese with English abstract), Primary studies on the remediation of municipal waste composting by plants, Hu X (1996): Primary studies on the remediation of municipal waste Plants experience oxidative stress upon exposure to heavy metals that leads to cellular damage. Environ Int. Environ Monit Assess. Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. Key wordsCadmium-heavy metal pollution-iron chloride-soil remediation. Goal, scope and background: The use of plants or plant products to restore or stabilize contaminated sites, collectively known as phytoremediation, takes advantage of the natural abilities of plants to take up, accumulate, store, or degrade organic and inorganic, This paper studied the tolerance of Arundo donax grown in a simulated heavy metals polluted wetland, and determined the biological characters and chlorophyll contents of the plant at its different growth stages as well as the changes of soil heavy metals contents. Four Red Tip Photinia (Photinia × fraseri Dress) trees and two Blueberry Muffin Hawthorn (Rhaphiolepis umbellata (Thunb.) Previous research reported that AM fungus (Glomus mosseae) increased the absorption of P for plant growth on red clover (Trifolium pratense) treated with different Zn rate levels. Effects of La3+ (with La treatment) compared with check groups was evidently observed. Amino acid sequence deduced from the amplified fragment also demonstrated a high homology (60% ∼ 75%) to the other known higher plant MT-like proteins and shared the similar structural characteristics of cys-Xaa-cys regions at both end of the sequence. Phytoremediation is emerging as a bio-based and low-cost alternative in the cleanup of heavy metal-contaminated soils. The overall risk of cancer for all the studied metals and for the three groups in dusty days was higher than non-dusty days (less than two per one million). Laboratory studies had demonstrated that "Merlin" could tolerate cadmium and copper up to 50 mg/L and 30 mg/L, respectively. gives the opportunity for detoxification of various elements and compounds, considered as contaminants, directly in the lumen of human intestine. A heavy metal responsive gene PvSR2 (Phaseolus vulgaris stress related) which encodes a new heavy metal stress related protein was isolated from a mercuric-chloride-treated bean (Phaseolus vulgaris L.) cDNA library by differential screening using cDNAs derived from treated and untreated plants.
