Resumo: | This study aimed to evaluate the use of two types of industrial waste to reduce availability of zinc and cadmium in contaminated soil. The experiment was conducted in a greenhouse at the Universidade Federal Rural do Rio de Janeiro during 225 days, using a substrate contaminated with zinc and cadmium, collected from the yard of the Itaguaí Port Mining Industry, and near the site of disposal of hazardous waste from two industries, Cia Mercantil and Industrial Inga in Itaguaí. The substrate was treated with two inerting agents: an industrial residue with characteristic alkaline (Slag of Melt Shop) in two doses, 4% and 6%, and a high content of iron oxide as adsorbent (lamination of scale) in a single dose of 1%. After planting the seedlings of Eucalyptus urophylla, substrate was collected from each experimental unit to determine the bioavailable and unavailable fractions (extracted with MgCl2). The substrate, untreated, had a high content of cadmium and zinc in the bioavailable fraction. The treatments caused a reduction in the availability of these elements in the soil, as evidenced in the differential absorption by plants. Due to the increased availability of cadmium and zinc in the soil without the addition of inerting agents, plants did not survive the high levels of these elements, and died 30 days after implantation of the experiment. The dry matter yield was positively influenced by the application of inerting agents, showing better response at higher slag. The highest dose also gave the lowest concentrations of elements in plants without causing nutrient deficiency of zinc and cadmium, maintaining levels that are not toxic to the species of eucalyptus. Although showing lower concentrations of cadmium at 6% Melt Shop Slag, this dose resulted in greater extraction of this element by plants. |

O experimento foi conduzido em casa de vegetação na Universidade Federal Rural do Rio de Janeiro por 225 dias, utilizando-se um substrato contaminado com zinco e cádmio, coletado no pátio de minério do Porto de Itaguaí, e próximo ao local de disposição de resíduo perigoso da Cia Mercantil e Industrial Ingá em Itaguaí, RJ. O substrato foi tratado com dois agentes inertizantes, assim descritos: um resíduo industrial com característica alcalina (Escória de Aciaria) em duas doses 4 e 6%, e outro com alto teor de óxido de ferro como adsorvente (Carepa de Laminação), em dose única de 1%. Após o plantio das mudas de Eucalyptus urophylla, foram feitas coletas do substrato em cada unidade experimental para determinação das frações biodisponíveis (extraído com MgCl2) e a não disponível. O substrato não tratado apresentava alto teor de cádmio e zinco na fração biodisponível. Os tratamentos causaram uma redução na disponibilidade desses elementos no solo, evidenciado na absorção diferenciada pelas plantas. Por causa da maior disponibilidade do cádmio e zinco no solo sem adição dos inertizantes, as plantas não resistiram aos altos teores desses elementos e morreram 30 dias após a implantação do experimento. A produção de massa seca foi influenciada positivamente pela aplicação dos agentes inertizantes, apresentando melhor resposta na maior dose de escória de aciaria. A maior dose também propiciou as menores concentrações dos elementos nas plantas, sem provocar deficiência do micronutriente zinco e mantendo o cádmio a níveis não tóxicos para as espécies de eucalipto. Apesar de apresentar menores concentrações de cádmio na dose de 6% de Escória de Aciaria,essa dose resultou na maior extração desse elemento pelas plantas.Universidade Federal de Santa Maria2011-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/322510.5902/198050983225Ciência Florestal; Vol. 21 No. 2 (2011); 219-227Ciência Florestal; v. 21 n. 2 (2011); 219-2271980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3225/1869Magalhães, Marcio Osvaldo LimaAmaral Sobrinho, Nelson Moura Brasil doMazur, Nelsoninfo:eu-repo/semantics/openAccess2017-05-03T18:46:01Zoai:ojs.pkp.sfu.ca:article/3225Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-03T18:46:01Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
