TL;DR: In this article, the metals, Cd, Pb, Cu, Zn, Mn and Fe were sequentially extracted from the dust into five fractions, exchangeable metal, carbonate bound metal, MnFe oxide bound metal and the residue.

TL;DR: The SLOWPOKE nuclear reactor as mentioned in this paper meets modern elemental analysis requirements; rapid multielement analysis of most types of samples is possible; the variable neutron flux (maximum 10 12 n cm -2 s -1 ) is stable, homogeneous and reproducible from day to day over a period of months.

TL;DR: The metal uptake behavior of these amine- and dithiocarbamate-cellulose derivatives were compared for Cu(II), Cd(II) and Pb(II).

TL;DR: In this article, the elemental compositions of house dust, street dust and soil have been determined for 26 elements on material collected in Christchurch, New Zealand, and the elements Hf, Th, Sc, Sm, Ce, La, Mn, Na, K, V, Al and Fe may be considered to be soil-based and contribute about 45-50% to house dust and 87% to street dust, while the elements which are enriched (>3 times) in the dusts relative to the levels found in local soils, are Br, Cu, Cl, Pb

TL;DR: Fourteen elements can be rapidly determined in whole blood by the neutron activation analysis procedure described and a further 13 elements are determined after overnight irradiation in the SLOWPOKE reactor.
