Determination of nonsteroidal antiinflammatory drugs in water samples using liquid chromatography coupled with diode-array detector and mass spectrometry.

An analytical method for the determination of trace levels of six different nonsteroidal antiinflammatory drugs (NSAIDs) in water samples has been developed and validated. Environmentally relevant pharmaceuticals were chosen according to human consumption in Poland. Final analysis of the target compounds was performed by RP LC-diode-array detection-MS, whereas sample preparation included an SPE step.

Physical, chemical, and biological changes in the Gulf of Gdańsk ecosystem (southern Baltic sea).

This review presents the present state of knowledge of the physical, chemical, and biological changes in waters of the Gulf of Gdańsk (Baltic Sea). The general characteristics of the Baltic Sea and the Gulf of Gdańsk with brief description of changes in the ecosystem are included. Among meteorological parameters describing climate in the coastal zone, water temperature changes together with considerations of precipitation and sea level are presented.

Monitoring of organic pollutants in coastal waters of the Gulf of Gdańsk, Southern Baltic.

This paper presents an overview of changes in organic pollution of coastal waters of the Gulf of Gdańsk (Baltic Sea). Toxic pollutants including volatile organic compounds (VOC), volatile organohalogen compounds (VOX), chlorophenols, phenoxyacids, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) were determined in seawater from the Gulf of Gdańsk coastal waters in the period 1996-2001. In the case of the Gulf of Gdańsk, non-conservative behaviour of VOC was observed due to random temporal and spatial of inputs along the Vistula estuary and to the dilution of VOC-enriched river water with seawater.
