Abstract [en]

Until now, the possibility for the personnel at the National University of Lao PDR (NUOL) to perform analysis of arsenic in drinking water as well as water used for agriculture has been limited to indication sticks, giving only a vague indication of the presence and levels of arsenic. Due to the lack of adequate and sensitive analytical instruments the levels of arsenic are relatively unknown in Lao People Democratic Republic (Lao PDR). A simple method of analyzing arsenic in water is using atomic absorption spectroscopy (AAS) coupled to a hydride generation system (HG). In support of this project, an HG with an AAS-oven has been delivered and installed at the inorganic lab at NUOL. The system has been optimized and tested and the personnel at the university have been instructed and trained in how to use the system. Sampling and analysis were supposed to be executed although this part of the project encountered many problems and could not be performed in a satisfactory way. Problems mainly came from lack of material, i.e. distilled water, and knowledge as well as monsoon weather conditions making the sampling impossible.
