This study investigated matrix effects in analytical procedures for butyltin (TBT,DBT and MBT) quantification and speciation in sediments and in two fish tissues (gill and liver) by gas chromatography with pulsed flame photometric detection (GC-PFPD) analysis. Unlike sediment samples,tissues exhibited a significant matrix effect,thus,the quantification should be made by curve over matrix to avoid quantification errors and loss of analytical accuracy. © 2013 Sociedade Brasileira de Química.998-1005engBiota tissuesButyltinGC-PFPDMatrix effectSedimentArtigo10.5935/0103-5053.20130129WOS:000321209600014Acesso aberto2-s2.0-848803107272-s2.0-84880310727.pdf2543372149131902
