17. Determination of mercury chemical speciation in the presence of low molecular mass thiols and its importance for mercury methylation
Abstract : Methylmercury (MeHg) is a neurotoxic compound that threatens the well-being of humans and wildlife. It is formed through the methylation of inorganic mercury (HgII) under suboxic/anoxic conditions in soils, sediment and waters. READ MORE

18. Development of Techniques and Methods for the Quantitative Analysis of Endogenous Substances by Microcolumn Liquid Chromatography Coupled to Mass Spectrometry
Abstract : Liquid chromatography-mass spectrometry (LC-MS) is a powerful technique for the analysis of endogenous compounds. The introduction of electrospray ionization (ESI) as an interface between LC and MS has contributed strongly to a trend towards miniaturization of LC, due to the possibility to perform ESI at low flow rates.

20. Protein Modifications by Low Molecular Weight Chemicals Inducing Airways Diseases
Abstract : Airways diseases are one of the most common health effects in the western world today. It has been shown that low molecular weight chemicals (LMWC) can cause airways diseases. The mechanisms for these diseases are not well known in most cases. Also, methods for biological monitoring of exposure are not available for many of these LMWC. READ MORE
