Resumo: | The use of guiding values has been the practice in countries with tradition in monitoring the quality of natural resources. The first step of a pollution monitoring program is to establish the natural concentrations of potentially toxic elements (PTEs) in uncontaminated soil to the development of background values. Mean values of total PTE concentration in worldwide are very heterogeneous and resulting from different soils, extraction methods and techniques of analytical determination. The background values recommended by CETESB were obtained from samples of 13 soils, submitted to USEPA SW 846 3050 protocol, whose PTE contents were determined by atomic absorption spectrometry. The objective of this work was to contribute to the improvement of background values of Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, V and Zn in tropical soils, using topsoil samples (0-20 cm) of 30 representative soils of State of São Paulo, Brazil, collected in areas without human disturbance. The soil samples were submitted to the USEPA SW 846 3051, 3051 A and 3052 protocols, with microwaveassisted acid digestion. Natural contents of PTEs were determined by inductively coupled plasma optical emission spectrometry (ICP OES). Extraction protocols were evaluated using the certified soil sample NIST SRM 2709 San Joaquin. Arithmetic means were adopted to describe the central tendency and the variation of results from the different acid digestions and to set the background values into 75 and 90 percentiles. Regardless the extraction method, the average contents of EPT were in the following range of variation (mg kg-1): Al - 27118-42865; Ba - 78-101; Fe - 6318- 35888; Cd - ND - 2.2; Co - 18 to 37; Cr - 39-59; Cu - 43-61; Mn - 176-623; Ni - ND - 61; V - 111-193 and Zn - 63 to 68. The contents of Al, Co, Cu, Fe, Mn, V and Zn correlated with clay, amorphous (Feox) and crystalline (FeDCB) iron oxides contents. The method 3052 resulted in PTEs recovery levels within the limits considered acceptable for certified sample. Within recommended methods by CONAMA Resolution n.420 / 2009, the 3051 A was the best correlated with the method 3052 and was considered the protocol with high potential to improve soil background values. The new soil background values were (mg kg-1): a) percentile 75: Al - 66,700; BA - 68; CD - 1.53; Co - 16; Cr - 47; Cu - 20; Fe - 24,830; Mn - 333; Ni - 57; V - 66; Zn - 61; percentile 90: Al - 99 820; Ba - 113; CD - 1.78; Co - 30; Cr - 62; Cu - 32; Fe - 39 280; Mn - 480; Ni - 113; V - 119; Zn - 65. Since new background values differed from those currently practiced by CETESB, the use of ICP OES to determine natural PTE levels extracted by USEPA 3051 A, from a larger and more representative set of soils, supported the improvement of background values and may contribute to the improvement of the environmental risk assessment estimates for edaphoclimatical conditions of the State of São Paulo. |

A primeira etapa de um programa de monitoramento de poluição é o estabelecimento das concentrações naturais dos elementos potencialmente tóxicos (EPTs) em solos não contaminados, para a definição de valores de referência de qualidade (VRQs). Valores médios da concentração total de EPTs no âmbito mundial são muito heterogêneos e decorrem da diversidade dos solos, dos métodos de extração e das técnicas de determinação analítica. Os valores de referência preconizados pela CETESB foram obtidos de amostras de 13 solos, submetidas ao protocolo USEPA SW 846 3050, cujos teores foram determinados por espectrofotometria de absorção atômica (AAS). O objetivo deste trabalho foi contribuir para o aprimoramento dos VRQs de Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, V e Zn em solos paulistas, utilizando amostras superficiais (0-20 cm) de 30 solos representativos dos limites estaduais, coletadas em áreas isentas de perturbação antrópica. As amostras de solo foram submetidas aos protocolos USEPA SW 846 3051, 3051 A e 3052, com digestão ácida assistida por forno micro-ondas. Os teores naturais de EPTs foram determinados por espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES). Os métodos de extração foram avaliados utilizando a amostra certificada de solo NIST SRM 2709 San Joaquin. Médias aritméticas foram adotadas para descrever a tendência central e a variação dos resultados provenientes das diferentes digestões e para definir os VRQs nos percentis 75 e 90. Independentemente do método de extração, os teores médios de EPTs apresentaram a seguinte amplitude de variação (mg kg-1): Al - 27.118 a 42.865; Ba - 78 a 101; Fe – 6.318 a 35.888; Cd – ND a 2,2; Co – 18 a 37; Cr – 39 a 59; Cu – 43 a 61; Mn – 176 a 623; Ni – ND a 61; V – 111 a 193; Zn – 63 a 68. Os teores de Al, Co, Cu, Fe, Mn, V e Zn correlacionaram-se com os teores de argila, de óxidos de ferro cristalinos (FeDCB) e de óxidos de ferro amorfos (FeOX) dos solos. O método 3052 resultou em teores percentuais de recuperação dentro dos limites considerados aceitáveis para a amostra certificada. Dentre os métodos recomendados pela Resolução CONAMA n.420/2009, o 3051 A foi o que melhor se correlacionou com o método 3052, sendo considerado o método com maior potencial para aprimorar os VRQs de solos do Estado de São Paulo. Os novos VRQs sugeridos para solos do Estado de São Paulo foram (mg kg-1): a) percentil 75: Al – 66.700; Ba – 68; Cd – 1,53; Co – 16; Cr – 47; Cu – 20; Fe – 24.830; Mn – 333; Ni – 57; V – 66; Zn – 61; percentil 90: Al – 99.820; Ba – 113; Cd – 1,78; Co – 30; Cr – 62; Cu – 32; Fe – 39.280; Mn – 480; Ni – 113; V – 119; Zn – 65. Os VRQs diferiram daqueles atualmente praticados pela CETESB, indicando que o uso do ICP OES para determinar teores naturais EPTs, extraídos pelo método USEPA 3051 A, a partir de um conjunto maior e mais representativo de solos, subsidiou o aprimoramento dos VRQs, podendo contribuir para a melhoria das estimativas de avaliação de risco ambiental para as condições edafoclimáticas do Estado de São Paulo.Não recebi financiamentoporUniversidade Federal de São CarlosCâmpus ArarasPrograma de Pós-Graduação em Agricultura e Ambiente - PPGAA-ArUFSCarQualidade ambientalSolos - poluiçãoElementos potencialmente tóxicosICP-OESsoil pollutionregulatory guidance valuespotentially toxic elementsmicrowave-assisted acid digestionICP OESenvironmental qualityCIENCIAS AGRARIASValores de referencia de elementos inorgânicos potencialmente tóxicos em solos do Estado de São Pauloinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisOnline600600442fce62-1385-47e9-866d-ee2534841345info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDissJLC.pdfDissJLC.pdfapplication/pdf2059088https://repositorio.ufscar.br/bitstream/ufscar/8023/1/DissJLC.pdf17e62a1a362fb497c4e79d993d9aae53MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://repositorio.ufscar.br/bitstream/ufscar/8023/2/license.txtae0398b6f8b235e40ad82cba6c50031dMD52TEXTDissJLC.pdf.txtDissJLC.pdf.txtExtracted texttext/plain189083https://repositorio.ufscar.br/bitstream/ufscar/8023/3/DissJLC.pdf.txtd51d42388007ead956509a5efa7a959eMD53THUMBNAILDissJLC.pdf.jpgDissJLC.pdf.jpgIM Thumbnailimage/jpeg5189https://repositorio.ufscar.br/bitstream/ufscar/8023/4/DissJLC.pdf.jpgd234a737e3226cf5a17ff649d72dd98eMD54ufscar/80232023-09-18 18:30:58.739oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:30:58Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |

The use of guiding values has been the practice in countries with tradition in monitoring the quality of natural resources. The first step of a pollution monitoring program is to establish the natural concentrations of potentially toxic elements (PTEs) in uncontaminated soil to the development of background values. Mean values of total PTE concentration in worldwide are very heterogeneous and resulting from different soils, extraction methods and techniques of analytical determination. The background values recommended by CETESB were obtained from samples of 13 soils, submitted to USEPA SW 846 3050 protocol, whose PTE contents were determined by atomic absorption spectrometry. The objective of this work was to contribute to the improvement of background values of Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, V and Zn in tropical soils, using topsoil samples (0-20 cm) of 30 representative soils of State of São Paulo, Brazil, collected in areas without human disturbance. The soil samples were submitted to the USEPA SW 846 3051, 3051 A and 3052 protocols, with microwaveassisted acid digestion. Natural contents of PTEs were determined by inductively coupled plasma optical emission spectrometry (ICP OES). Extraction protocols were evaluated using the certified soil sample NIST SRM 2709 San Joaquin. Arithmetic means were adopted to describe the central tendency and the variation of results from the different acid digestions and to set the background values into 75 and 90 percentiles. Regardless the extraction method, the average contents of EPT were in the following range of variation (mg kg-1): Al - 27118-42865; Ba - 78-101; Fe - 6318- 35888; Cd - ND - 2.2; Co - 18 to 37; Cr - 39-59; Cu - 43-61; Mn - 176-623; Ni - ND - 61; V - 111-193 and Zn - 63 to 68. The contents of Al, Co, Cu, Fe, Mn, V and Zn correlated with clay, amorphous (Feox) and crystalline (FeDCB) iron oxides contents. The method 3052 resulted in PTEs recovery levels within the limits considered acceptable for certified sample. Within recommended methods by CONAMA Resolution n.420 / 2009, the 3051 A was the best correlated with the method 3052 and was considered the protocol with high potential to improve soil background values.
