Marine bivalves (Mytilus galloprovincialis) were exposed to titanium dioxide (10 mg L(-1)) either as engineered nanoparticles (nTiO2; fresh, or aged under simulated sunlight for 7 days) the bulk equivalent. Inductively coupled plasma-optical emission spectrometry analyses of mussel tissues showed higher Ti accumulation (>10-fold) in digestive gland compared gills. Nano-sized TiO2 greater than bulk, irrespective ageing, particularly (>sixfold higher). Despite this, transcriptional expression...
A preliminary study to classify tea by geographical origin using trace metal concentrations was made. Fifteen types of from ten different countries were digested nitric acid. The digests then analysed for their contents either inductively coupled plasma-atomic emission spectrometry the more concentrated analytes (Al, Ba, Ca, Cu, Fe, La, Mg, Mn, Sr, Ti and Zn) or plasma mass less (Cd, Co, Cr, Cs, Hg, Li, Nd, Ni, Pb, Pr, Rb, Se, Sn, Ti, V Zr). data obtained these results UNSCRAMBLE, a...
Experimental verification of lower-hybrid rf current drive in the Versator II tokamak is presented. The experiments show that efficient exists only low-density discharges (${\overline{n}}_{e}\ensuremath{\lesssim}6\ifmmode\times\else\texttimes\fi{}{10}^{12}$ ${\mathrm{cm}}^{\ensuremath{-}3}$) "slide-away" regime where a preformed suprathermal electron tail prior to application power.
This review covers advances in the analysis of advanced materials, metals, fuels and lubricants, nanostructures, ceramics, refractories, organic inorganic chemicals, catalysts nuclear materials by a range techniques including X-ray, ICP, LIBS, mass spectrometry, synchrotron-based techniques, plus non-destructive ablation surface techniques.
This review period has seen some changes to the format of review. These are intended more accurately reflect current state analytical research in analysis metals, chemicals and materials. As a consequence, title section headings have been altered this. Significant areas growth include use LIBS remote analysis, especially explosives nuclear The stand-off capability technique makes it very desirable these areas. chemometrics procedures for removing substrate interferences proving be effective...
COVID-19 caused levels of household food insecurity to spike, but the precarity so many people in wealthy countries is an outgrowth decades eroding public provisions and labour protections that once protected from hunger, setting stage for virus' unevenly-distributed harms. The prominence corporate-sponsored foodbanking as a containment response pandemic-aggravated follows replacing rights with charity. We review structural drivers charity's growth hunger solution North America, its spread...
The uptake of platinum group elements (PGE) by different preparations estuarine sediment suspended in filtered river water has been examined. For a given PGE, adsorption time courses to untreated and whose hydrous metal oxides or organic matter had removed appropriate chemical treatments were similar. Adsorption Rh(III) Pt(IV) proceeded via first-order reversible reaction. Rh, forward rate constants 1 order magnitude greater than reverse constants, but for Pt, comparable. Respective system...
The chemical and biogeochemical reduction of pertechnetate (TcO4-) perrhenate (ReO4-) have been compared alongside complexation the reduced species by three anthropogenic ligands relevant to nuclear waste (ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic (NTA), isosaccharinic (ISA)). An HPLC size-exclusion column coupled ICP-MS was used separate quantify Tc Re. During method development, ReO4- showed recalcitrance direct Sn(II) under conditions that readily TcO4- resulted in...
The main objective of this investigation is to determine the concentration and accumulation heavy metals in coastal sediments Southeastern Black Sea Turkey. selected sampling area has mainly been affected by anthropogenic activities, such as agricultural, untreated domestic treated industrial wastewater, mining. Metal enrichment factor (EF), geo-accumulation index (Igeo), metal pollution (MPI) have calculated relative contamination levels evaluated at all stations. In study, maximum EF...
In the present study, concentrations of arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) were measured in muscle, gill, gonads pelagic fish species Trachurus mediterraneus, Engraulis encrasicolus ponticus, Sprattus sprattus that are important both commercially for ecosystems Black Sea. The samples collected during 2011. metals determined using inductively coupled plasma mass spectrometry (ICP-MS) following an acid...
