So far, numerous in-situ and ex-situ methods have been developed and electro-kinetic (EK) enhanced phytoremediation is widely accepted as a sustainable alternative for the decontamination. The integrated technique contains the application of a low intensity electric field adjoined to growing plants in contaminated soil. So far, many efforts have been made while there is a clear lack of this technology in both laboratorial and field applications. Limitations such as low phytoavailaibility of target metals, unsatisfactory metal's tolerance and translocation ability of plants and undesirable soil pH environment might the main reasons that responsible for the low remediation efficiency. In order to figure out the current focusing phenomena, the possible mechanisms of phytoextraction, EKR and EKR-enhanced phytoextraction were discussed, respectively. In addition, influencing factors such as metal speciation, plant selection and electro-kinetic parameters were also discussed. The contents summarized in the present paper are believed to be an useful guideline for further investigation and optimization of EK-enhanced phytoextraction.","PeriodicalId":15742,"journal":{"name":"Journal of Environmental and Analytical Toxicology","volume":"262 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79673231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LANL now operates as a multidisciplinary research institution. As part of an ongoing assessment of siterelated ecological risk, organochlorine pesticides, their metabolites, polycyclic aromatic hydrocarbons, polychlorinated biphenyls (PCBs), and 2,3,7,8-tetrachlorodibenzo-p-dioxin toxic equivalents (TEQs) were evaluated in western bluebird (Sialia mexicana) and ash-throated flycatcher (Myiarchus cinerascens) eggs relative to a developed but non-industrial reference area; PCBs and TEQs were also evaluated in nestlings. Chemicals were below detection limits in the majority of samples. Western bluebird eggs collected from the study area had significantly lower concentrations of dieldrin, oxychlordane, and trans-nonachlor when compared with eggs from the reference area. No differences were observed in concentrations of dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyltrichloroethane (DDT), and heptachlor epoxide. Ash-throated flycatcher eggs contained higher total TEQ concentrations when compared with western bluebird eggs; however, no differences in concentrations of DDE, DDT, dieldrin, or total PCBs were observed. No differences were observed in total PCBs or TEQs in nestlings between the two species. Western bluebird eggs contained higher levels of total PCBs and TEQs when compared with nestlings; no differences were observed in total PCBs or TEQs between ash-throated flycatcher eggs and nestlings. Chemical concentrations detected in eggs of both species were below levels that are associated with adverse effects reported in the scientific literature, suggesting that concentrations of organic chemicals observed here appear to be at levels causing negligible risks to local bird populations.","PeriodicalId":15742,"journal":{"name":"Journal of Environmental and Analytical Toxicology","volume":"211 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77488024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They range from process industries, fabrication workshops, service centres, food and drink premises, and several others. A majority of these sprawled up in urban areas though they are also seen in peripheral and rural areas. These centres play significant role in the national economy. At the same time, they also produce a variety of end products and byproducts in solid, liquid or gaseous forms which affect the environment negatively by polluting air, water and soil. This has resulted in eutrophication of water bodies, contamination of groundwater, soil and affected quality of life in the cities. There are well laid out pollution control regulations and guidelines in the country. The Federal Ministry of Environment, The National Environmental Standards and Regulations Enforcement Agency (NESREA) with five Zonal offices implement these regulations.

Passive samplers results revealed that ozone was significantly lower (24.2 ppb) in April compared to May, June (49 ppb). The mean pods number/plants, length/plant, and biomass of both fresh and dry weight of EDU and NEDU treated plants were all significantly not different. The mean biomass for EDU leaves was (4.0 g) and significantly reduced compared to NEDU (2.8 g). The mean root length and shoot biomass of EDU plants compared to NEDU treated plants remained unchanged. However, the total biomass of EDU plants were significantly higher (10.0 g) compared to NEDU (7.3 g). The overall plant biomass was 30% significantly higher than N-EDU plants. The nutritional quality parameters (Ash, Moisture, Fats, Fiber and Protein) reduced significantly in NEDU seeds compared to EDU. The %moisture contents of seeds was (F=0.017; p<0.05), %Ash (F=3.987; p<0.05), %Protein (F=3.467; p<0.05) %Fats (F=2.574; p<0.05), %Fiber content was positively affected by EDU treatment.

Its prevalence is alarmingly high among young male sugarcane workers in Nicaragua and El Salvador. The absence of known etiologies for CKD, such as hypertension and diabetes, has led researchers to explore a number of potential risk factors, though none adequately explain the timing and epidemic nature of the disease. In this paper, we explore the idea that glyphosate, an herbicide routinely used on sugarcane, could play a significant causal role in MeN, mediated by its property as an analogue of the coding amino acid glycine. Glyphosate is a glycine molecule with a methyl phosphonyl group attached to its nitrogen atom. Its substitution in place of glycine could disrupt multiple proteins critical for kidney health. Here, we first present prior evidence from the research literature that glyphosate may be substituting erroneously for glycine. In particular, multiple species of both bacteria and plants have mutated to remove a highly conserved glycine residue in the enzyme in the shikimate pathway that is disrupted by glyphosate, and this mutation has caused the enzyme to be completely insensitive to glyphosate. We have identified multiple proteins with key roles related to kidney function, whose disruption by glyphosate substitution for critical glycine residues could explain most of the unique features of MeN. Specifically, glycine substitution in aquaporin, chloride channels, cytochrome C oxidase and collagen, among others, could contribute to dehydration, increased urinary acidification, renal fibrosis, rhabdomyolysis and mitochondrial dysfunction. While the hypothesis that glyphosate could be disrupting protein synthesis is not yet proven, it is remarkable how well it explains multiple features of MeN. Investigations to verify whether glyphosate is in fact disrupting protein synthesis are urgently needed.","PeriodicalId":15742,"journal":{"name":"Journal of Environmental and Analytical Toxicology","volume":"165 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80425030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
