NO This lecture presentation outlines methods for sampling and analysing water for mercury monitoring. It explains mercury behaviour in aquatic systems, sampling techniques, container selection, and stabilisation. Laboratory procedures include extraction, digestion, and spectrometric analysis. Emphasis is placed on quality control, accurate recording, and reducing contamination to ensure reliable measurement of low mercury concentrations.
