Invited

Neutron activation analysis (NAA) is a well-established analytical technique for the simultaneous measurement of multielement concentrations. The most common forms of NAA are instrumental (INAA), radiochemical (RNAA) and preconcentration (PNAA). We have previously reported the development of speciation NAA (SNAA). We are also interested in the development of biochemical NAA (BNAA) methods for...

406. Nuclear and Related Analytical Techniques Used to Study Atmospheric Deposition of Trace Elements and Radionuclides in Rural and Urban Areas Experiencing Environmental Stress

Experience in applying mosses as biomonitors of trace elements and radionuclides in some selected rural and urban areas affected by intense anthropogenic activity is reviewed. Among them the western part of the Kola Peninsula (NW Russia), the most heavily industrialized area in the entire Arctic; the South Urals (Karabash) counted among the most polluted areas in the world where human impact...

370. Measurement of selenium levels in cultivated Japanese and Korean oysters and Japanese rock oysters using the 17.4-s neutron activation product 77mSe

Nuclear Analytical Methods

Verbal

Oysters in Japan are mainly cultivated in Miyagi, Hiroshima, and Hokkaido Prefectures. Sometimes baby cultivated oysters are exchanged between Japan and Korea; so both cultivated oysters are said to be genetically similar. Since Japanese consume a fair amount of raw oysters, it is of interest to compare the elemental levels of oysters from different areas. Soft tissues of cultivated Japanese...

188. Comparison of INAA and LC-ICP-MS for the determination of As species in marine tissues

Dr Rolf Zeisler (National Institute of Standards and Technology)

Nuclear Analytical Methods

Verbal

The aim of this work was to acquire traceable quantitative results for total As in whole samples as well as in extracts containing As species. Instrumental neutron activation analysis (INAA) is well suited for such measurements and is used in this work to validate the As mass fraction determined by liquid chromatography combined with inductively coupled plasma mass spectrometry (LC-ICP-MS) in...

28. Biosorption of Chromium and Nickel from Wastewater by Microalgae Nostoc Linckia

The present study relates to the use of microalga Nostoc linkia for the removal of chromium and nickel from wastewater of galvanic industry. During one hour experiment 70% of chromium and 50% of nickel were removed from the wastewaters. To determine concentrations of Cr and Ni in wastewater samples atomic absorption spectrometry was used. The samples of dry nostoc biomass after exposure to...
