Ion fluxes and hematological parameters of two teleosts from the Rio Negro, Ama...
Baldisserotto, Bernardo; Chippari-Gomes, Adriana Regina; Lopes, Nilva Pereira; Bicudo, José Eduardo Pereira Wilken; Paula-Silva, Maria Nazaré N.The aim of this study was to describe the effect of hypoxia on whole body ion fluxes and hematological parameters in two Amazonian teleosts: Serrasalmus eigenmanni and Metynnis hypsauchen. The increase of Na+ and Cl- effluxes on M. hypsauchen exposed to hypoxia may be related to an increase of gill ventilation and effective respiratory surface area, to avoid a reduction in the oxygen uptake, and/or with the dec...
Influência da matéria orgânica na adsorção do fungicida triadimenol pelo solo
Lopes, Nilva Pereira; Queiroz, Maria Eliana Lopes Ribeiro de; Neves, Antônio Augusto; Zambolim, LaércioThe adsorption of triadimenol (1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol) on soil samples with varying contents of organic matter was studied. The adsorption was described by means of the Freundlich's isoterm. An increase in the capacity of adsorption was observed as the content of organic carbon in the matrix increased. That effect was observed when removing the organic matter from t...
