Resumo: | This work aimed to identify the main variables affected by natural factors and, or anthropic, which influence the quality of surface water in watersheds, managed for eucalyptus wood production. Water quality was monitored in four watersheds located in Aracruz, northern ES state, Brazil. The physical and chemical characteristics of the water and the potential presence of pesticides used in forest management were evaluated. Samples were collected after the silvicultural activities and, or, rainfall between the months of January to June 2012. Principal component and factor analysis techniques were used to determine the water variables most sensitive and correlated with forestry activities, soil and climatic conditions of the study watersheds. It was possible to obtain four components that explained 73.1% of the total variance. The components were correlated with the variables and defined as factors mineral, solid, acidity, and pedological. These factors explained 31.6; 18.5; 15.6; and 7.4% of the total variance of the data which are directly related to salinity, the presence of suspended solids, acidity and the inorganic carbon content of the soil, respectively. Sulfluramid (insecticide) and glyphosate (herbicide) were not found. In general, it is possible to reduce from 30 to 12 variables that should be monitored for prediction of water quality, maintaining at least 70% of the precision of the estimates. The evaluation of these key variables allows establishing an adequate monitoring system of water quality considering the eucalyptus forestry activities. |

A qualidade da água foi monitorada em quatro microbacias localizadas no município de Aracruz, norte do ES, Brasil. Para tanto, analisaram-se as características físicas e químicas, bem como a potencial presença na água de agrotóxicos utilizados no manejo florestal. As coletas foram realizadas após as atividades silviculturais e/ou ocorrência de chuvas entre os meses de janeiro e junho de 2012. Foram utilizadas técnicas de componentes principais e análise fatorial para determinar as variáveis mais sensíveis e correlacionadas com as atividades silviculturais e com as condições edafoclimáticas das microbacias. De forma geral, 4 componentes explicaram 73,1% da variância total. Os componentes foram correlacionados com as variáveis analisadas e definidos como fatores: mineral, sólido, acidez e pedológico. Estes fatores explicaram 31,6; 18,5; 15,6; e 7,4% da variância total dos dados e estão diretamente relacionados com a salinidade, a presença de sólidos suspensos, a acidez e o teor de carbono inorgânico do solo, respectivamente. Não foi observada presença dos agrotóxicos sulfluramida (inseticida) e glifosato (herbicida) em todas as avaliações realizadas. Em geral, é possível reduzir de 30 para 12 as variáveis que devem ser monitoradas para predição da qualidade da água, mantendo pelo menos 70% da precisão das estimativas.Universidade Federal de Santa Maria2018-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3159010.5902/1980509831590Ciência Florestal; Vol. 28 No. 1 (2018); 127-140Ciência Florestal; v. 28 n. 1 (2018); 127-1401980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31590/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessGardiman Junior, Benvindo SirtoliGarcia, Giovanni de OliveiraCecílio, Roberto AvelinoLoos, Rodolfo AraújoMafia, Reginaldo GonçalvesAbad, Jupiter Israel MuroSimão, João Batista PavesiBarbosa, Vitor Hugo Breda2018-04-23T18:10:31Zoai:ojs.pkp.sfu.ca:article/31590Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-04-23T18:10:31Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
