This year’s posters will include latest work on the determination of total gaseous mercury in ambient air. Coal-burning power plants are the largest anthropogenic source of mercury emissions to the air. Burning hazardous wastes, the chlor-alkali industry, crematoria, breaking mercury products, and spilling mercury, as well as the improper treatment and disposal of products or wastes containing mercury, can also release it into the environment. The recent ATEX certification has cemented the position of the PSA CEM instrumentation on many a wishlist.
The Clean Air Mercury Rule provides a regulatory regime for the control of mercury emissions from coal-fired utilities in the United States. The rule requires the installation of continuous emission monitoring systems at the majority of such utilities and provides a detailed regime of tests to validate data from the emissions monitoring system. Our poster on our “in the field” experience of a mercury continuous emission monitoring system gives an insight into PSA capabilities for the provision of specific instrumentation for this area of interest.
USEPA Methods 245.7 and Method 1631 for the determination of low level total mercury in water are based on vapor generation atomic fluorescence spectrometry (CV-AFS) and the range of PSA Millennium Merlin Systems offer exceptional results for these methods.
The PSA 10.055 Millennium Excalibur offers unrivalled results for the speciation of arsenic, antimony and selenium. A poster describing its application for the speciation of As and Se Metabolites in Human Urine will also be presented.
