mercury iodide is a scarlet-red odorless tasteless powder that is sensitive to light. It is insoluble in water and sinks to the bottom of a vessel when it is exposed to water. It is highly toxic by ingestion, inhalation and skin absorption.
mercury iodide soluctions are moderate to highly concentrated liquid solutions of mercury iodide for use in chemical synthesis and solution deposition. They are available in 55 gallon drums, smaller units and liquid totes.
High-Temporal-Resolution Laboratory Experiments
Three high temporal-resolution laboratory experiments have been conducted to study the behaviour of iodine and mercury (and bromine only in 2016) in surface snow during different seasons. One experiment took place during the polar night, one during the spring when the night and day cycle was present, and one during late spring with full sunlight.
2015 – continuous light conditions: iodine concentration (g – dark green line) and its enrichment factor (f – dark green solid line), sodium (h – dark red line) and total mercury in surface snow (d – grey lines for raw data and black line for the three-point smoothing) show a diurnal cycle connected with incoming solar radiation. However, during the snowfall event the signals decouple.
The results show that both iodine and mercury can undergo surface recycling re-emission processes. The GEM and the surface snow de-trended Hg concentrations (d – blue line) exhibit a positive correlation whereas the GEM and the surface snow de-trended iodine concentrations (f – dark green line) show a negative correlation.
