“…In situ techniques are generally preferred because they cause less site disturbance, less contaminant exposure to the environmental professionals and public in the vicinity, and they are often less complicated and more economical [141][142][143][144][145][146]. Also, because radionuclides are not destroyed, ex situ remediation requires sites for waste disposal, which have to meet special acceptance criteria and are limited [147].…”

“…New remediation technologies are under development in the physical and/or chemical areas, however most of them are still in the initial phase of elaboration [111]. However, the trend of emerging technologies are focused in methods in which the contaminants can be destroyed or carefully removed with low risk of secondary contamination [112].…”

“…Desta forma a exposição de pessoas ao mesmo é reduzida e o seu custo pode ser menor. Entretanto, devem-se observar condições específicas como climáticas, características químicas e físicas do solo e de produtos químicos(OLEXSEY;Parker, 2006).Quando se compara com remediação in-situ, o tratamento ex-situ requer maiores custos para escavação do solo, transporte, disposição e reenchimento do local, porém o tratamento pode ser melhor gerenciado e acelerado, alcançando melhores resultados em curto espaço de tempo (WUANA;OKIEIMEN 2011; LIU et al, 2017).A região do Oeste da Bahia ocupa uma área de 117.000 km 2 e encontra-se Bahia está à margem esquerda do Rio São Francisco e possui três importantes rios: O Rio Corrente, localizado no médio São Francisco, abrangendo o oeste e o noroeste do estado da Bahia e compreende treze municípios distribuídos em microrregiões homogêneas(PANQUESTOR et al, 2004); o Rio Carinhanha é afluente da margem esquerda do Rio São Francisco, entre os paralelos 13°50ˑ e 15°30ˑ de latitude sul e os meridianos 43°40ˑ e 46°10ˑde longitude, abrangendo uma área aproximadamente de 1.730.000 hectares(BORGES, 2009). A bacia hidrográfica do Rio Grande está inserida entre as coordenadas geográficas 10º10' e 13º20'S de latitude e 43º08' e 46º37'O de longitude, localizada no médio São Francisco representando 12,6% da área de drenagem e com área total próximo a 75.000 km2.Nesta região ainda se encontra o sistema aquífero Urucuia (SAU), que representa uma associação de aquíferos que ocorrem em arenitos flúvio-eólicos do Grupo Urucuia, Neocretáceo da bacia Sanfranciscana, que compõe a maior parte da cobertura fanerozóica do Cráton do São Francisco.…”

SANTOS, D.S. Heavy metals content evaluation in western Bahia. 2019. 124 p. Thesis (Doctorate in Agronomy)-Federal University of Uberlândia. 2 Heavy metals in agricultural areas and native Cerrado in western Bahia All and any activity has the potential to add to the environment heavy metals with the potential to cause contamination of soil, water and air damaging and often irreversible. The process of food production requires the use of inputs for the control pests and diseases and others capable of altering the chemically and physically properties of the soil to ensure high yields. However, the intensive and continued use to such inputs can add heavy metals to the soil. To ensure that activities such as the process of producing food is safe, and minimize any risk to the health of people, animals and the preservation of the environment. For that to happen, in addition to the use of inputs free of toxic elements assessments of the levels of soil must be carried out in order to verify potential risks. Therefore, the aim of this work is to evaluate the risk of contamination by heavy metals in western Bahia, determining the levels of Ba, Cd, Co, Cr, Cu, Ni, Zn, Mn, Al and Fe in agricultural áreas and in the native Cerrado. For this purpose, 10 áreas were selected in the West of Bahia: A1= Anel da Soja, A2 = Placas; A3= Bela Vista; A4 Novo Paraná; A5 = Panambi, A6= Coaceral; A7 = Alto Horizonte; A8 = Roda Velha; A9 =Roda velha de baixo e A10 = Cascudeiro. In each área, 8 properties were selected. Soil samples were collected in each soil at two depths (0-10 cm and 10-20 cm) in the following soil preparation systems: conventional tillage system (CT); no tillage (NT) and native Cerrado (NC). Aqua regia was used for extraction of the metals, and the extracts were dosed in ICP-Plasma. For the univariate procedures, we used descriptive statistics, Tukey test variance analysis, and the Student t test. The correlations between the variables were determined by calculating Pearson correlation coefficient. For the multivariate procedures, the principal component analyzes (PCA) were used.The results showed that the áreas A5 (Panambi) and A6 (Coaceral) presented higher levels of heavy metals in relation to the others áreas. The values of heavy metals found in the western region of Bahia are lower than the reference values of quality of other states. The soil preparation systems CT and NT presented higher levels than the NC áreas. The increasing order of heavy metals found in the CN was: Cd> Co> N i> Ba> Zn> Cr> Mn > Fe> Al.
