DOIAbstract
Ainda que as ferramentas analíticas venham evoluindo significativamente ao longo dos anos, a determinação de concentrações de compostos orgânicos a níveis residuais (por exemplo, 0,99, homocedástico), alta detectabilidade (LQ 1,0 μg kg-1), precisão (CV0,99, homocedástico; precisão com CV 0.99, homoscedastic), high detectability (LOQ 1.0 μg kg-1), precision (CV 0.99, homoscedastic; accuracy with CV <2.1%; veracity with CV <2.2%). The efficiency of incorporation of ERI into feed was 72% and the method was able to produce feed with adequate homogeneity (CV <2.0%) of the ERI concentration and low leaching (<1.1%) of the compound when in contact with the water for up to 15 minutes. The depletion study was carried out on pacu fish and invo...
