Resumo: By using radiometric techniques, sorption and movement of the insecticides aldrin, DDT, lindane, malathion, parathion and the fungicide carbendazim were determined in laboratory in seven soils from the "cerrado" of the State of São Paulo. Aldrin and DDT were more sorbed by all soils. Soil thin-layer chromatography experiments showed that aldrin and DDT exhibited also the lowest Rf indicating that they are less mobile. The relationship between sorption of pesticide and physical-chemical characteristics of soils was determined by linear correlation analysis. These studies demonstrated significant correlation between sorption coefficient of aldrin, lindane, malathion, parathion and the organic matter content of soils. High significant correlation was also found between sorption coefficient of aldrin, malathion, parathion and clay content.

O aldrin e DDT demonstraram ser os mais sorvidos por todos os solos. Ensaios de mobilidade por cromatografia em camada delgada dos solos indicaram que aldrin e DDT apresentaram os menores Rf, significando menor mobilidade. A relação entre sorção dos pesticidas e características físico-químicas dos solos foi determinada por análise de correlação linear. Estes estudos demonstraram correlação significativa entre o coeficiente de sorção do aldrin, lindano, malation e paration e o conteúdo de matéria orgânica dos solos. Encontrou-se também correlação altamente significativa entre o coeficiente de sorção do aldrin, malation e paration e o conteúdo de argila.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLuchini, Luiz CarlosHirata, RodobikoRüegg, Elza Flores2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15366Pesquisa Agropecuaria Brasileira; v.19, n.2, fev. 1984; 157-162Pesquisa Agropecuária Brasileira; v.19, n.2, fev. 1984; 157-1621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15366/9236info:eu-repo/semantics/openAccess2014-04-16T19:16:05Zoai:ojs.seer.sct.embrapa.br:article/15366Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:16:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
