Following ingestion, mercuric oxide is readily converted to mercuric chloride, the most dangerous mercury compound. Mercuric oxide dust has a corrosive effect on eyes, skin, and respiratory tract. People with a history of allergies or known sensitization to mercury, chronic respiratory disease, nervous system disorders, or kidney disorders are at increased risk from exposure. (EPA, 1998) |

| 정리 방법 | Cleanup: Mercury removal from wastewater can be accomplished by these processes: BMS processchlorine is added to the wastewater, oxidizing any mercury present to the ionic state. The BMS adsorbent (an activated carbon concentrated of sulfur compound 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. TMRIMAC Process: wastewater is fed into a reaction whereby a slight excess of chlorine is maintained, oxidizing any mercury present to ionic mercury. The liquid is then passed through the TMRIMAC ion exchange resin where mercury ions are adsorbed. The mercury is then stripped from the spent resin with hydrochloric acid solution. /Mercury compounds/Mercury spills should be cleaned up immediately by use of a special vacuum cleaner.

| 비화재 누출 대응 | Caution : Extreme temperatures (in excess of 932 degrees F) may decompose mercuric oxide into mercury and oxygen. Avoid sources of extreme heat.Isolate hazard area. Stay upwindkeep out of low areas. Do not touch spilled material. Take up small spills with sand or other non-combustible absorbent material and place into containers for later disposal. For small, dry spills, use clean shovel to place material into clean dry containers. Dike far ahead of large spills for later disposal. (EPA, 1998) |
| 처리 방법 | SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.Disposal: Metal collect all droplets and pools at once by means of suction pump and aspirator bottle with a long capillary tube. Cover fine droplets in nonaccessible cracks with calcium polysulfide and excess sulfur. Combine all contaminated mercury in a tightly stoppered bottle. Hold it for purification or sale.

| 건강 영향 | Mercury 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.

| 독성 요약 | High-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.
