Solid-phase microextraction for determination of 3-chloro-4-(dichloromethyl)-5-...
Rezemini,Andrea L.; Vaz,Jorge M.; Carvalho,Lilian R. F.Solid-phase microextraction, using on-line bis(trimethylsilyl)trifluoroacetamide derivatisation, gas chromatography, and mass spectrometry, was evaluated in the quantification of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) in water samples. Fibres encompassing a wide range of polarities were used with headspace and direct immersion sampling. For the immersion procedure, various parameters affectin...
Application of Geostatistics to Soil and Groundwater Samples Contaminated by Pe...
Jorge M. Carvalho; António FiúzaA geoenvironmental site investigation/characterization survey took place in a contaminated costal area in the surroundings of an active oil refinery having an associated petrochemical complex, located north of Porto, in the north-western part of Portugal. In this context, several soil and groundwater samples were collected, respectively in trenches and boreholes, and chemically analyzed allowing the characteriz...
