“…The elevated concentrations of Cu, Zn, and Pb were reported to be common in mixed-MSW composts, recyclable urban garbage, and compost-amended soils around the world. 5,17,36 This common feature may be attributed to progressive mineralization and natural composting of the raw MSW constituting the bulk of the soil at Dhapa. 5 However, the degree of contamination, the enrichment factors, and the chemical species in MSW-contaminated soils will be different from different localities, societies, ethnic behaviors, climates, and economic statuses.…”

“…Firstly, energy-dispersive X-ray fluorescence (EDXRF), which is a proven tool for determining bulk elemental concentrations in soil samples, 16,17 was used to obtain the absolute mass fractions of the elements in the MSWcontaminated samples and also the control soil sample. The 109 Cd-Si(Li) EDXRF setup detects elements with characteristic X-rays in the range 3-20 keV, viz.…”

“…O sinal é amplificado e o espectro de raios-X analisado em um software específico para identificação dos elementos químicos presentes na amostra a partir de suas linhas de energia (Figura 1). Desta maneira, é possível realizar análises qualitativas e quantitativas a partir de curvas de calibração previamente construídas (ANJOS et al, 2002;MARGUÍ et al, 2005;JOSHI et al, 2006;SOUSA et al, 2013). Preparação e análise dos materiais de referência Porções teste de aproximadamente 0,5 g foram acondicionadas em cápsulas de polietileno cilíndricas e vedadas com filme de polipropileno específico para análise por EDXRF.…”
