“…2002). An advantage of PIXE is its ability to determine simultaneously dozens of elements without the need for sample dissolution or digestion prior to analysis (Smodis 2007). ICP‐AES also has the ability to determine a wide range of elements and is used for the determination of low atomic number elements such as Na and Mg (Zhang et al.…”

“…ICP‐AES is commonly used when funds are limited since it presents a significant advantage of less costly instrumentation as compared with other multi‐element techniques (Zachariadis and Michos 2007). A possible disadvantage of the ICP technique is the destructive sample preparation method prior to actual analysis (Smodis 2007). Improper preparation could lead to contamination of samples (Ruth et al.…”

Particle-induced X-ray emission (PIXE) and ICP-AES can be combined to obtain a wider range of detected elements, augment previous data and ⁄ or to verify measured concentrations of heavy and trace metals in geological samples. Intercomparison of data sets generated by multiple techniques is challenging due to the differing processes and methods of each technique. Here, we compare elemental data obtained by both techniques for aeolian dust from Owens (Dry) Lake, California. Nineteen elements were detected by PIXE, sixteen by ICP-AES and ten elements were detected by both techniques. Statistical analyses of data set groupings illustrated which parameters differed significantly between PIXE and ICP-AES. Relative variation (%) showed that PIXE gave higher concentrations than ICP-AES for Al, As, Cu, Fe, K, Mn, Ni, Sr, Ti and Zn in all samples. For As, Cu, Sr and Zn, relative variation was variable between the techniques. PIXE detection limits exceeded ICP-AES concentrations for Ba, Cd, Co, Cr, Pb and Mo. Low ICP-AES percentage recoveries of Al, Fe, K, Mn and Ti for NIST SRM 2710 indicated incomplete dissolution during digestion (EPA Method 3050B), since elements were bound in silicate structures. Variability between the two data sets is explained by differences between analytical techniques, sample preparation methods and ⁄ or variability in sample matrices.

“…They spread over large geographical areas, allowing comparison of the pollutant content in ecosystems from diverse regions (Sawidis et al, 1993;Dragovic et al, 2004;Smodis, 2007). The ecological interpretation of radioactivity values in mosses might be conceptually easier than that relative to higher plants, since these organisms take up radiocesium from a single main source.…”

“…As perennial and slow-growing organisms, they maintain a fairly uniform morphology with time and that provides a record of the history of the radionuclide supply in the environment, keeping the memory of past pollution events (Testa et al, 1999;Boulyga et al, 2003). In temperate areas in Europe, like Greece, moss is the most frequently used biomonitor, since its comparable advance is the potential for retrospective monitoring (Smodis, 2007).…”

A B S T R A C TThere is a growing pressure from the environmental authorities and public bodies to reduce anthropogenic pollution. Stringent environmental legislation is being implemented for industries around the world, even more so for coal consuming industries. Control of gaseous emissions is one of the areas that are receiving considerable attention towards sustainable development. Coal combustion in coal-fired power utilities emits SO x to the atmosphere. Dry flue gas desulphurisation (FGD) is a well known technology often used to mitigate sulphur emissions in coal-fired power utilities. It traditionally uses lime to neutralise SO x , and forms a mixture of anhydrite (CaSO 4 ), and calcium sulphite (CaSO 3 ). Several options are reported in literature for the utilisation and management of FGD by-product. However, this paper reports on the preliminary findings of the option where excess FGD by-product is co-disposed with gasification/bottom ash and brines. The study examined the influence of moisture content, chemistry of the liquid medium, and ratio of FGD by-product to gasification ash on the physical and chemical properties of the cured mix. The results demonstrate that the chemistry of raw materials influences the final properties of the resultant product.
