Resumo: | The environmental contamination by metallic trace elements is a problem that is getting worse around the world due to the growth and the technologic development of the humanity. Among the main sources of this kind of contamination are the atmospheric deposition of particles in soils located around industrial complexes and the prolonged and concentrated application of organic wastes in the soil. When present at the soil surface, these elements will migrate in depth and may reach the subsurface water bodies, causing their contamination. This study aimed to use the software Hydrus-2D to simulate the vertical redistribution of zinc, lead and copper in soil profiles contaminated by air pollution or by the application of swine liquid manure as well the transfer of these metallic trace elements into the groundwater. Chemical models were used under different hypotheses of reactivity of these elements with the soil particles and the physical, hidric and chemical characteristics of each soil profile. In the attempt to validate these models, it was simulated the vertical transports of zinc and lead, between 1900 and 2000, at three uses of a soil in northern France and of zinc and copper, between 2000 and 2008, at a soil profile located in Santa Maria RS, Brazil. Using a two sites chemical model with the kinetic constant decreased to 1% of the value measured in the laboratory, the simulations of the vertical transport of the metallic trace elements were validated in all soil profiles. This model was able to redistribute efficiently these elements in the profile, according their concentrations determined in situ. It was also predicted that the transfer of these contaminants do not represent, until now, any risk of pollution of the groundwater. Even with the continued application of high doses of swine liquid manure until 2058, the predicted increasing of zinc and copper concentrations in soil solution will not represent a risk of subsurface waters pollution. However, the model estimated that copper will be accumulated on the surface of this profile in greater quantities than zinc, increasing its concentration to levels above the value of intervention to agricultural areas. It was concluded that Hydrus-2D was a useful tool in detecting and/or forecasting environmental problems arising from the accumulation of metallic trace elements in soil and its leaching to the subsurface water bodies. |

Ela é decorrente do crescimento e do desenvolvimento tecnológico da humanidade, que apresenta, entre as principais fontes, as contaminações oriundas da deposição atmosférica de partículas aos solos localizados no entorno de complexos industriais e da aplicação concentrada e prolongada de resíduos orgânicos. Uma vez presentes na superfície do solo, esses elementos migrarão em profundidade, podendo atingir os corpos de água subsuperficiais e contaminá-los. Este trabalho teve por objetivo principal usar o programa computacional Hydrus-2D para simular a redistribuição vertical de zinco, chumbo e cobre no perfil de solos contaminados por poluição atmosférica ou pela aplicação de dejeto líquido de suínos e a transferência desses elementos traços metálicos rumo ao lençol freático. Para tal, foram usados modelos químicos sob diferentes premissas de reatividade dos elementos com as partículas do solo e as características físico-hídricas e químicas de cada perfil de solo. Buscou-se validar estes modelos, simulando os transportes verticais de zinco e chumbo, entre 1900 e 2000, em três usos de um solo do norte da França e de zinco e cobre, entre 2000 e 2008, num perfil de solo localizado em Santa Maria RS, Brasil. Utilizando um modelo químico de dois sítios com a constante cinética diminuída a 1% do valor medido em laboratório, as simulações do transporte vertical dos elementos traços metálicos foram validadas em todos os perfis de solo. Esse modelo foi capaz de redistribuir eficientemente estes elementos no perfil, conforme suas concentrações determinadas in situ. Ele também previu que a transferência destes contaminantes não representou, até o momento, nenhum risco de poluição da água do lençol freático. Mesmo com a manutenção da aplicação de altas doses de dejeto líquido de suínos até 2058, o aumento na concentração de zinco e cobre na solução do solo previsto não representará risco à poluição das águas subsuperficiais. Porém, o modelo estimou que o cobre se acumulará na superfície deste perfil em maior quantidade que o zinco, elevando sua concentração para níveis acima do valor de intervenção para áreas agrícolas. Dessa forma, o Hydrus-2D apresentou-se como uma ferramenta muito útil na detecção e/ou previsão de problemas ambientais decorrentes do acúmulo de elementos traços metálicos no solo e da sua lixiviação para os corpos de água subsuperficiais.Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloSantos, Danilo Rheinheimer doshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4785480Z6Robaina, Adroaldo Diashttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721472P9Jacques, Rodrigo Josemar SeminotiMallmann, Fábio Joel Kochem2017-03-242017-03-242009-02-27info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfMALLMANN, Fábio Joel Kochem.
