Determination of aluminium in human serum at normal concentration level by the use of chromatographic and mass spectrometric methods

A new analytical procedure using separation support based on Convective-interaction media (CIM®) was developed for speciation of Al in human serum at normal concentration levels. The separation of proteins was performed on a weak anion-exchange CIM® diethylamine (DEAE) monolithic column and was followed by UV detection. Separated Al species were detected on-line by ICP-MS.

Metabolism studies of diclofenac and clofibric acid in activated sludge bioreactors

Two environmentally relevant pharmaceuticals, the non-steroidal antiinflammatory drug, diclofenac and the pharmacologically active metabolite of several serum triglyceride-lowering pharmaceuticals, clofibric acid, were subjected to microbiological transformation in activated sludge bioreactors, and the production of breakdown products was studied.

The use of stable isotopes for source appointments of mercury in the Gulf of Trieste

The use of stable isotope fractionation of Hg in sediments of the Gulf of Trieste identified the amount originating from idrija mercury mine as opposed to Hg originating from the other parts of the Mediterranean.

Introduction of threat analysis into the land-use planning process;

The key features of the threat analysis can be summarised as follows. It consists of three main steps. The first is determination of the threat intensity level of an accident, the second is analysis of the environmental vulnerability of the surroundings of an accident, and the third, integrating the previous two, is determination of a threat index in the accident impact zone. All three are presented in GIS based maps, since this is a common expression in LUP. It can and should be applied in the early stages of the LUP process

Are the commercially avable enymes suitable for detrmination of selenium species?

The aim of this work was to check if commercially available enzymes are pure enough to be used for selenium speciation analysis and what contribution could impurities have on Se determination on a real sample basis. For this purpose, twelve commercially available enzymes of different origin and classification (protease, amylase, cellulase, lipase) were analysed. After the dissolution of the enzyme in water, separation of Se species was made by ion exchange chromatography, with inductively coupled plasma mass spectrometry used as the detection system.
