摘要：

In this work, a simple and low cost method based on solid liquid extraction with low temperature partitioning (SLE-LTP) was optimized and validated for the residue analyses of the pesticides thiamethoxam, triadimenol and deltamethrin in pineapple samples using gas chromatography with electron capture detector (GC-ECD). The SLE-LTP technique was proven satisfactory with recoveries up to 90% and linear chromatographic response for the analytes, ranging from 0.04 to 1.30 mu g g(-1) with correlation coefficients above 0.99. The limits of quantification for the pesticides were lower than the allowed maximum limits of residues established for these pesticides in pineapple by the European Union. (C) 2014 Elsevier Ltd.
