RESUMO

Rare Earth Element Concentrations in Brazilian Benchmark Soils

“…The abundance of REEs found here is very similar to that reported for soils of Brazil (Paye et al, 2016) and other countries (Wei et al, 1991;Yoshida et al, 1998;Tyler and Olsson, 2002;Sadeghi et al, 2013) and follows the Oddo-Harkins rule, which holds that elements with an even atomic number (such as Ce) are more common than elements with an odd atomic number (such as La). ) were also found in higher concentrations than trace elements (Ni and Co) measured in the same soils (Biondi et al, 2011). In addition, the average Gd concentration was greater than the average Cd concentration generally found in Brazilian soils (Paye et al, 2010;Santos and Alleoni, 2013;Preston et al, 2014).…”

“…Data on soil background concentrations of trace (Salonen and Korkka-Niemi, 2007;Biondi et al, 2011;Preston et al, 2014;Alfaro et al, 2015) and major elements (Montserrat and Camarero, 2010;Hannan and Tanguma, 2012;Dantu, 2014) are easily found in the literature. However, data regarding REEs are comparatively scarce and have mainly focused on determination of REEs in a limited number of soil types (Turra et al, 2011;Damascena et al, 2015).…”

Valores de referência de qualidade para metais pesados em solos do Rio Grande do Norte

“…Os valores definidos pelo método EPA 3051A fornecem o pseudototal dos metais no solo. Dessa forma, o NIST recomenda a comparação com as recuperações com base nos valores lixiviados (Biondi et al, 2011a). …”

“…A determinação desses teores é de extrema importância na definição de valores orientadores, além de ser indispensável à construção de uma legislação voltada ao monitoramento e à intervenção legal compatível com a realidade local, de forma a se evitarem intervenções inadequadas que acabem em prejuízos financeiros e sociais (Baize & Sterckeman, 2001;Horckmans et al, 2005;Biondi et al, 2011a). Portanto, valores orientadores de referência de qualidade para solos devem refletir a concentração natural de determinada substância no solo e, desse modo, fornecer a base para a avaliação da sua qualidade (Teng et al, 2009 (Conama, 2009).…”

Solid Waste in Agricultural Soils: An Approach Based on Environmental Principles, Human Health, and Food Security

“…For this it is necessary to sample the soil taking into account the diversity of soil classes and the original materials existing in the region, seeking to perform the collections in minimally preserved soils, with litle or no apparent signs of anthropic interventions, since the pedogenetic processes and the geochemical formation of each region interfere directly with the natural contents of these substances [42,64,65].…”
