Resumo: The objective of this work was to evaluate copper and arsenic toxicity in agricultural soils, by means of standardized bioassays of chronic and acute toxicity on Eisenia foetida, and to relate E. foetida response to copper and arsenic concentrations in soils. The agricultural soils were sampled in the proximity of copper mining industries, in the Aconcagua river basin, Chile. E. foetida exposed to the studied soils exhibited a low mortality, indicating the absence of acute toxicity. Besides, a decrease in the cocoon production and juvenile development was observed, indicating the existence of chronic toxicity. Reduction in the cocoon production and juvenile development was related to soil concentrations of copper and arsenic. Both copper and arsenic reduced the cocoon production, while only arsenic diminished the juvenile development. Agricultural soils from mining areas of the basin have potentially toxic characteristics for the development of soil macrofauna.

Los suelos agrícolas fueram muestreados en las inmediaciones de áreas mineras en la cuenca del río Aconcagua, Chile. E. foetida expuesta a los suelos estudiados mostró una baja mortalidad, indicando la ausencia de toxicidad aguda. Además, se observó una disminución en la producción de capullos y desarrollo de juveniles, indicando la existencia de toxicidad crónica. Dicha disminución fue relacionada con las concentraciones de cobre y arsénico en los suelos. El cobre y arsénico en conjunto disminuyeron la producción de capullos, mientras que sólo el arsénico disminuyó el desarrollo de juveniles. Suelos agrícolas provenientes de áreas mineras de la cuenca poseen potenciales características tóxicas para el desarrollo de la macrofauna edáfica.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraÁvila, GonzaloGaete, HernánMorales, MarioNeaman, Alexander2007-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7585Pesquisa Agropecuaria Brasileira; v.42, n.3, mar. 2007; 435-441Pesquisa Agropecuária Brasileira; v.42, n.3, mar. 2007; 435-4411678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAspahttps://seer.sct.embrapa.br/index.php/pab/article/view/7585/4504info:eu-repo/semantics/openAccess2010-09-20T15:02:58Zoai:ojs.seer.sct.embrapa.br:article/7585Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-09-20T15:02:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
