Spectroscopy as a Non-Destructive Method to Study Terrestrial Dust Particles: Case Study from United Arab Emirates
The aim of this study is to evaluate the effects of physical and chemical sand characteristics, such as moisture content, organic content, and magnetic content on spectral signals using spectro-radiometer and Hyper-spectral camera. JMP Pro software is used to determine the correlation between moisture content percentage, organic content percentage, magnetic content percentage and reflection percentage. All samples have a fine sand texture with a pH ranging from 7.76 to 8.88 and electrical conductivity varies between 900.1 μS to 1539 μS. Results show that organic content ranges from 0.501% to 4.094%, moisture content has a range from 0% to 1.219%, and magnetic varies between 1.062% and 2.907%. Heavy metals (Ba, Cd, Cr, Mn, Ni, Pb, and Zn) are detected in all samples with lower concentration than the maximum limit sit by U.S Environmental Protection Agency. X-ray diffraction shows that all samples contain quartz and graphite.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
