Chemically enhanced phytoextraction has been proposed as an effective approach to removing heavy metals from contaminated soil through the use of high biomass plants. Using pot experiments, the effects of the application of EDTA, EDDS and citric acid on the uptake of Cu, Pb, Zn and Cd by corn (Zea mays L. cv. Nongda 108) and bean (Phaseolus vulgaris L. white bean) plants were studied. The resul...

collected into the sodium citrate-containing tube, which showed normal platelet counts. Only a few cases of PGPS have been reported [1-4]. To our knowledge, this is the first case to be reported in Korea. Stavem and Berg [1] described EDTA-induced ‘platelet stain preventing factor’, and Mant et al. [2], Cockbill et al. [3], and Toyota et al. [4] reported platelet degranulation caused by EDTA. U...

Ethylenediamine-N,N,N’,N’-tetraacetic acid calcium (II) disodium salt (Ca (II)-EDTA) was investigated for its antibacterial activity against the periodontal pathogens Aggregatibacter actinomycetemcomitans, Prevotella intermedia and Porphyromonas gingivalis. We determined the minimum inhibitory concentrations (MIC) of Ca (II)-EDTA and its bactericidal activity. Ethylenediamine-N,N,N’,N’-tetraace...

Across many environments, nitrate (NO_3(-)) is an important form of N available for microorganisms and photosynthetic organisms. Accurate NO_3(-) measurements are important for examining N cycling and retention in terrestrial and aquatic ecosystems, but a common method of NO_3(-)) analysis can underestimate NO_3(-)) concentrations when soluble iron is present (iron > 10 mg L(-1)). The basic met...

Rats immunosuppressed by the administration of cyclophosphamide and cortisone acetate and then infected with Aspergillus fumigatus were treated with an antifungal drug, EDTA, or a combination of one of the antifungal agents, amphotericin B lipid complex (ABLC; 5 mg/kg of body weight/day for 7 days), and EDTA (30 mg/kg/day for 7 days). The mortality rate was reduced, the duration of survival was...

hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...

Measurements of circulating parathyroid hormone (PTH) are important in the evaluation of individuals with hyperor hypocalcemia and for the investigation of PTH function in bone and mineral disorders (1, 2). Serum may be a good alternative to EDTA plasma in the assessment of PTH status and is an acceptable alternative to EDTA plasma in the reformulated IMMULITE 2000 intact PTH (iPTH) assay. Howe...
