“…The mining wastes originated at in the CartagenaLa Union mining district and its heavy metals content have been previously studied (Gonzalez-Fernandez et al 2007) and the preliminary screening of the interaction with the different compartments of the environment (soil, water and vegetation) have also been investigated (Marguí et al 2007;Robles-Arenas et al 2006;Clemente et al 2006;Marguí et al 2004;Marques et al 2003). Remarkable concentration of heavy metals were also determined in Mar Menor lagoon sediments as it has been noticed in previous studies (Simonneau 1973;Diaz del Rio 1993).…”

“…It consists on a tungsten X-ray tube (Philips X-ray generator, PW 1140/00/60 3 kV) with a changeable metal secondary target. The X-ray tube, the secondary target-for this experimental work molybdenumand the sample are placed in a triaxial geometry (Gonzalez-Fernandez et al 2007). This allows a decrease in the background, and a better peak/ background ratio, thus enabling a good limit of detection for metal pollutants, especially for vegetation.…”

The distribution and mobility of heavy metals in the non-saturated zone of the alluvial plain of a wadi in the Cartagena-La Union mining district was investigated. The elemental chemistry of soils, indepth sediments and different plant species (namely Hirsfeldia incana, Ditrichia viscosa and Piptatherum miliaceum) was carried out by using X-ray fluorescence and X-ray diffraction techniques. Potential mobility of metals was assessed by using lixiviation test runs (DIN 38414-S4). Concentrations detected in soils and sediments were higher than the acceptable limits reported in official regulations. Regarding metals mobility, values obtained for Pb, Zn and As exceed the limits established by European Union for DIN 38414-S4 leachates. Whilst the obtained leaching percentages for Pb, Cu and As were not especially high (<2%), Zn exhibit a very high leaching potential (up to 60% of the total metal content), involving potential risk of pollution events.

“…At the same time, the class II values are the levels classifying the waste as hazardous waste. Cr, Ni, Cu and Zn content were the criteria to qualify the waste as belonging to one of the different classes [37]. All four metals in the present study were below class II, and hence, we considered EMHS as an inert material of class I that needed to be deposited in controlled landfills.…”

Environmental pollution due to discharges of heavy metal containing sludge from textile industries is a common nuisance in Bangladesh, where no treatment of sludge is carried out before final disposals. Energy Dispersive X-ray Fluorescence (EDXRF) was employed in the present study to analyze the heavy metal content of Electrocoagulated Metal Hydroxide Sludge (EMHS) collected from a composite textile industry. Thirteen heavy metals, viz., Mn, Ti, Cu, Zn, Ni, Sr, V, Cr, Zr, Hg, Cd, Nb and Ga, were detected. Mn, Ni, Cu, Zn and Cd exceeded the permissible limit to apply the EMHS in agricultural land. Cr, Ni, Cu and Zn were compared to the values of the European legislation to evaluate the environmental risk and to classify the wastes as inert wastes or as wastes that have to be control landfilled. EMHS was categorized as class I and needs to be deposited in controlled landfills.

“…This allows a decrease in the background, using the advantages of the effect of polarization of the incident X-ray beam from the tube. The system was also previously applied for mining wastes analysis (Gonzalez-Fernandez et al 2007). Three specimens of 0.250 g of each powdered plant were pressed into pellets of 2.0 cm of diameter without any chemical treatment.…”

A geochemical and mineralogical characterization of three zones (namely oxides zones, hydrothermal alteration zone and mining wastes zone) from a mineralized zone in the upper part of the Cartagena-La Unión range was carried out by analysing rocks, soils and three plant species (Piptatherum miliaceum, Ditrichia viscosa and Hirsfeldia incana). The transference and bioavailability of some metals (especially Pb, Zn, As and Fe) from soils to plants was also checked. Results show that rocks have a large content of Fe and Pb which are transferred to surrounding soils also highly enriched in these elements (Fe ranges from 9 to 35% and Pb 1 to 2.9%). Regarding soil to plant transfer, it was shown a differential behaviour for both the three plant species and the soil zones, with a higher level of metal accumulation rates for Piptatherum miliaceum in the hydrothermal alteration zone. Values of accumulation rates obtained for Pb in Piptatherum miliaceum allow considering it a good choice for phytoremediation purposes.
