ANALYSIS OF Cr, Fe, Mn, Ni AND Zn FROM MOSSES BY NAA, AAS AND ICP-AES METHODS
Journal Title: Journal of Science And Arts - Year 2009, Vol 11, Issue 2
Abstract
Nuclear Analytical Methods can be used for research activities on environmental studies like water quality assessment, pesticide residues, global climatic change (transboundary), pollution and remediation. Heavy metal pollution is a problem associated with areas of intensive industrial activity. The moss biomonitoring technique was employed in this work to study the atmospheric deposition in Dambovita County Romania together with complementary nuclear and atomic analytical methods: Neutron Activation Analysis (NAA), Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). These high sensitivity analysis methods were used to determine the elemental composition of some samples of mosses placed in different vision areas with different pollution industrial sources. The concentrations of Cr, Fe, Mn, Ni and Zn were determined. The concentration of Fe from the same samples was determined using all these methods and we obtained a very good agreement, in statistical limits, which demonstrate the capability of these analytical methods to be applied on a large spectrum of environmental samples with the same results.
