Solid-phase extraction (SPE) has become and important and frequently employed method for the preconcentration of organic pollutants from water samples. From the methodological standpoint, two basic approaches can be recognized, on-line and off-line,

A practical liquid chromatographic early-warning system for polar pollutants in water ought to have detection limits at a level below a microgram per litre. Using ultraviolet absorbance detection this normally necessitates trace enrichment of the sam

An isocratic column liquid chromatographic system with UV absorbance detection at 230 nm has been developed for the rapid trace-level determination of a large number of polar pollutants in water. The systems contains two precolumns, in series, which

The pollution of the Nitra river (Slovakia), a left-bank tributary of the river Danube, by organic microcontaminants was monitored in 1993 and 1994. Water samples were taken at six sites every two months, transported in a portable refrigerator and pr
