“…The elements concentration found in the PG samples are of the same order of magnitude of values available in the literature for the Brazilian PG (Saueia et al, 2013a). Concentrations below the detection limits were observed for the elements As, Cd and Se in PG samples from Cubatão and Uberaba.…”

“…Depending upon the level of radioactivity the TENORM industries are subjected to the recommendations given by Comissa˜oNacional de Energia Nuclear (CNEN), which include compliance with the radiological protection regulations [1,2]. Several publications are available in the literature related with the radiological characterization of Brazilian phosphogypsum [3][4][5][6], however few publications discuss the metals' characterization in phosphogypsum.…”

Phosphogypsum is a by-product of the phosphate fertilizer industry. It is produced by precipitation during wet process of phosphate rocks, thus posing serious problems with its utilization and safe disposal. In Brazil, three main industries are responsible for the production and storage of about 5.5 Â 10 6 tons per year. Phosphogypsum may contain trace metals and radionuclides of U and Th series. Since, in Brazil, phosphogypsum has been used for many years as soil amendment, it is important to know its availability in the environment. The main objective of this study is to evaluate the radionuclides and metals transfer in the soil-to-plant system. To accomplish this task an experiment was carried out in a green house, where two major crop groups (soya bean and corn) and leafy vegetables (lettuce) were grown in two types of soil (clay and sandy) amended with phosphogypsum. The transfer-factors were evaluated for the metals (As, Cd, Cu, Ni and Pb, Ba, Co, Cr, Fe, Zn and REE) and for the radionuclides U, Th, 226 Ra, 228 Ra, 210 Pb and 210 Po. The addition of PG to the two soils studied, did not significantly alter the TFs values for all the elements studied.
