“…However, our results (Fig. 4) support an important role of Al compounds, in agreement with Se studies in Japanese volcanic soils (Nakamaru et al, 2005). The acidic leachates rich in dissolved Al are those which do not follow the relation between As and Se.…”

“…They can have high Se concentrations (e.g. 6-15 mg/kg in Hawaii compared to 0.4 mg/kg as worldwide average), but in contrast show low Se mobility (Byers et al, 1938;John et al, 1975;Nakamaru et al, 2005). This low mobility is believed to originate from adsorption on Fe and Al minerals (John et al, 1975;Nakamaru et al, 2005), which have been widely reported as potential adsorption phases for Se (Balistrieri and Chao, 1990;Dynes and Huang, 1997;Parida et al, 1997;Wijnja and Schulthess, 2000;Duc et al, 2003;Peak et al, 2006;Fernández-Martínez and Charlet, 2009).…”

“…Os valores de K d são muito importantes do ponto de vista ambiental, pois refletem a afinidade dos elementos químicos pelos constituintes da fase sólida do solo (Fontes & Alleoni, 2006 (Nakamura et al, 2005). Os outros solos apresentaram valores de K d bem inferiores aos do LVA, indicando que, mesmo em subsuperfície e talvez pela baixa ou ausência concentração de goethita, o Se é muito pouco retido e pode ser facilmente lixiviado e estar prontamente disponível para as plantas.…”

“…À medida que seu estado de oxidação é aumentado, o Se torna-se mais móvel e menos retido no solo (Neal, 1995). Em regiões de alta umidade e, ou, de solos ácidos, selenito é a espécie química predominante (Neal, 1995;Nakamaru et al, 2005). Sob condições de neutralidade ou alcalinidade, selenito tende à oxidação, passando para a forma de selenato (Girling, 1984;Geering et al, 1968).…”
