Resumo

The present study evaluated the matrix effect associated to determination of butyltin compounds (tripropyltin (TPrT), tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MBT)) in sediment and mussel tissues using derivatization by Grignard reaction and quantification by gas chromatography coupled mass spectrometry (GC-MS). A non-negligible matrix effect was verified for sediments (54.2, 20.3, 13.6 and -53.6 %) and mussel tissues (-12.5, -32.0, 59.4 and 65.7 %) for TPrT, TBT, DBT and MBT respectively. However, this matrix effect was prevailed by preparing the analytical curves using standard addition techniques. Thus, an analytical method was optimized and validated for a more accurate and precise determination of butyltin compounds in sediment and mussel tissue samples.
