Physical DescriptionMercuric subsulfate, [solid] appears as a lemon-yellow powder or bright yellow scaly material. Very slightly soluble in water and denser than water. Hence sinks in water. Toxic by inhalation and by ingestion.
Other Experimental PropertiesProved to be mercury oxonium sulfate in x-ray studies of its structure. Polymeric oxonium cations (Hg3O2)x form 2-dimensional infinite layers. The sulfate ions lie inside loops of wide-meshed cation lattice.

LuftstandardsListed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Mercury oxide sulfate is included on this list.

Erste HilfeExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
ReinigungsverfahrenMercury spills should be cleaned up immediately by use of a special vacuum cleaner. Then the area should be washed with a dilute calcium sulfide solution. Small quantities of mercury can be picked up by mixing with copper metal granules. ... /Mercury/Mercury removal from waste water can be accomplished by these processes: BMS processChlorine is added to the waste water, oxidizing any mercury present to the ionic state. The BMS adsorbent (an activated carbon concentrate of sulfur cmpd on its surface) is used to collect ionic mercury. The spent adsorbent is then distilled to recover the mercury, leaving a carbon residue for reuse or disposal. TMR IMAC ProcessWaste water is fed into a reactor, whereby a slight excess of chlorine is maintained, oxidizing any mercury present to ionic mercury. The liquid is then passed through the TMR IMAC ion-exchange resin where mercury ions are adsorbed. The mercury is then stripped from the spent resin with hydrochloric acid solution. /Mercury cmpds/SPILLED MERCURY CMPD OR SOLN CAN BE CLEANED UP BY ANY METHOD THAT DOES NOT CAUSE EXCESSIVE AIRBORNE CONTAMINATION OR SKIN CONTACT. /MERCURY COMPOUNDS/1) Ventilate area of spill. 2) Collect spilled material for reclamation using commercially available mercury vapor depressants or specialized vacuum cleaners. /Inorganic mercury/

Preventive MeasuresIf material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. /Mercury compound, liquid, NOS/Personnel protection: Avoid breathing dusts, and fumes from burning material. Keep upwind. Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. ... If contact with the material anticipated, wear appropriate chemical protective clothing. /Mercury compound, solid, NOS/Personnel protection: Keep upwind. Avoid breathing vapors. ...

Gesundheitliche AuswirkungenMercury mainly affects the nervous system. Exposure to high levels of metallic, inorganic, or organic mercury can permanently damage the brain, kidneys, and developing fetus. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing, and memory problems. Acrodynia, a type of mercury poisoning in children, is characterized by pain and pink discoloration of the hands and feet. Mercury poisoning can also cause Hunter-Russell syndrome and Minamata disease. (L7)

ToxizitätsübersichtHigh-affinity binding of the divalent mercuric ion to thiol or sulfhydryl groups of proteins is believed to be the major mechanism for the activity of mercury. Through alterations in intracellular thiol status, mercury can promote oxidative stress, lipid peroxidation, mitochondrial dysfunction, and changes in heme metabolism. Mercury is known to bind to microsomal and mitochondrial enzymes, resulting in cell injury and death. For example, mercury is known to inhibit aquaporins, halting water flow across the cell membrane. It also inhibits the protein LCK, which causes decreased T-cell signalling and immune system depression. Mercury is also believed to inhibit neuronal excitability by acting on the postsynaptic neuronal membrane. It also affects the nervous system by inhibiting protein kinase C and alkaline phosphatase, which impairs brain microvascular formation and function, as well as alters the blood-brain barrier. Mercury also produces an autoimmune response, likely by modification of major histocompatibility complex (MHC) class II molecules, self peptides, T-cell receptors, or cell-surface adhesion molecules.

Signs and SymptomsCommon symptoms include peripheral neuropathy (presenting as paresthesia or itching, burning or pain), skin discoloration (pink cheeks, fingertips and toes), edema (swelling), and desquamation (dead skin peels off in layers). (A5)
