Instrumental Neutron Activation Analysis (INAA) using Ghana Research Reactor (GHARR -1) at the Ghana Atomic Energy Commission (GHAEC) Operating at 15kw at thermal flux of 5x10 11 n Cm -2 s -1 was used to determine nine trace elements in Talinum triangulare and Telfaria occidentalis that are commonly sold and consumed in most parts of Nigeria. The trace elements analyzed are: Mg, V. CL, AL, Mn, ...

The present study aims the identification and quantification of trace elements in two types of honey samples: Orchard honey and Wild honey from mainland Portugal. Chemical elements content was assessed by Instrumental Neutron Activation Analysis (INAA). Concentrations were determinated for Ag, As, Br, Ca, Cl, Cs, Cu, Fe, K, La, Mg, Mn, Na, Rb, Sb, Sc, U, V and Zn. The nutritional values of both...

We used instrumental neutron activation analysis (INAA) to determine antimony in small quantities of hair from individuals living in an area of endemic leishmaniasis. The groups studied were 12 patients undergoing treatment with N-methylglucamine antimoniate, 34 patients who had received such treatment a year ago, and 17 control subjects (untreated) who were living in the same area. Patients re...

Sodium peroxide (Na2O2) fusion coupled to Inductively Coupled Plasma Tandem Mass Spectrometry (ICP-MS/MS) measurements was used to rapidly screen quartz-rich geological samples for rare earth element (REE) content. The method accuracy was checked with a geological reference material and Instrumental Neutron Activation Analysis (INAA) measurements. The used mass-mode combinations presented accur...

In this work a determination of selected elements in the infant formulas commercially available on the Polish market was done. 14 different materials (milk-based formulas and grain porridges) were analyzed. Both, inductively coupled plasma mass spectrometry (ICP-MS) and instrumental neutron activation analysis (INAA) were applied for the determination of As, Cr, Fe and Se, which are recognized ...

Multielements in a typical Japanese diet certified reference material prepared at the National Institute for Environmental Studies (NIES) of Japan, in collaboration with the National Institute of Radiological Sciences (NIRS) of Japan were determined by instrumental neutron activation analysis (INAA). Five samples (ca. 510-1000 mg) and comparative standards were irradiated for a short time (10 s...

Knowing the relationship between pollution sources and air concentrations is crucial. Mathematical modeling a suitable method for assessment of this relationship. The aim research was to compare results Analytical Dispersion Modelling Supercomputer System (ADMOSS), which used in large areas, with moss biomonitoring. For comparison purposes, mathematical collection samples biomonitoring Czech–Po...

Opening of the Blanka Tunnel Complex (BTC) in Prague, Czech Republic, longest city tunnel Europe, significantly increased traffic on a connected main road, V Holešovičkách street (VHS). To study environmental changes VHS with BTC opening, sampling road dust and airborne particulate matter vicinity started 3 years before opening continued until pilot operation. The enrichment factors calculated ...

Most analytical techniques do not comply with the need for direct trace element analysis of samples exceeding the order of grams. Instead, sub-sampling methods are used to obtain representative sampling of the initial material. The possibilities arising from directly analyzing voluminous samples have been discussed [4]. Instrumental Neutron Activation Analysis (INAA) is a powerful technique, wh...
