Carbbean LFC asked does anyone know the environmental life of mercury vapour and zinc oxide?

i searched for it but i couldn't find it in my books and i don't think this is common web info...thanks in advance i read through all of that to NOT see the environmental life thats a million

And got the following answer:

Mercury is one of the most potent chemical inhibitors of thiol-sensitive enzymes and mercury vapor easily penetrates into the central nervous system. Dr. Boyd Haley PDF Version, 77 KB CAS#: 7439-97-6 UN#: 2024 (liquid compounds) Synonyms include colloidal mercury, quicksilver, liquid silver, metallic mercury, and hydrargyrum. Persons exposed to elemental mercury vapor do not pose a significant risk of secondary contamination to response personnel outside the Hot Zone. Persons whose skin or clothing is contaminated with liquid mercury can contaminate response personnel by direct contact or off-gassing vapor and can also contaminate equipment leading to a risk of chronic exposure for response personnel. Elemental mercury is a heavy, shiny, silver-white, odorless liquid. It is nonflammable, but releases toxic vapor, especially when heated. Odor does not provide any warning of hazardous concentrations. Inhalation is the primary route of exposure to elemental mercury vapor or aerosols, which are readily absorbed. Virtually no elemental mercury is absorbed from the gastrointestinal tract or by the skin. Mercury crosses the placenta and can be transferred to infants via breast milk. General Information Health Effects Prehospital Management Emergency Department Management Patient Information Sheet Follow-up Instructions Contact Information General Information Description There are three classes of mercury: metallic elemental mercury (quicksilver, Hg0), inorganic mercurial salts (e.g., Hg2Cl2, Hg+, HgCl2, Hg+2), and organic mercurials (e.g., methylmercury, phenylmercury). Adverse effects from exposure to mercury differ depending on the form and the route of exposure. This Medical Management Guideline focuses on elemental mercury. At room temperature, metallic or elemental mercury is a heavy, shiny, silver-white, odorless liquid. It is only slightly volatile at room temperatures and significantly more volatile when heated. Elemental mercury is nonflammable and has low solubility in both water and organic solvents. Routes of Exposure Inhalation Inhalation of mercury vapor is the primary route of exposure to elemental mercury. Inhaled vapor is almost completely absorbed by the lungs (75-80%). Neither liquid mercury nor mercury vapor has an odor and thus, chemical odor provides no warning of hazardous concentrations. Mercury vapor is heavier than air and may therefore accumulate in poorly ventilated or low-lying areas. Children exposed to the same levels of mercury vapor as adults may receive larger doses because they have greater lung surface area:body weight ratios and increased minute volumes:weight ratios. In addition, they may be exposed to higher levels than adults in the same location because of their short stature and the higher levels of mercury vapor found nearer to the ground. Skin/Eye Contact Elemental mercury vapor is only slowly absorbed through the skin, but causes irritation of both skin and eyes and may produce contact dermatitis. Ingestion Elemental mercury, a liquid at room temperature, is essentially nontoxic when ingested because virtually none (less than 0.1%) is absorbed. Anatomic gastrointestinal abnormalities such as enteric fistulas or intestinal perforation can sequester sufficient quantities of ingested elemental mercury to allow significant oxidation and subsequent absorption. Sources/Uses Elemental mercury is inexpensively produced by heating mercury-containing ores and condensing the vapor. Metallic mercury has many applications in the electrical industry (e.g., alkaline batteries, electrical switches, lights), in dental amalgrams, and in medical equipment (e.g., thermometers, electroanalysis). In the chemical and mining industries, mercury is used as a catalyst in reactions to form polymers, in manufacturing chlorine and caustic soda, and in extracting gold from ore. Mishandled or spilled mercury from devices used in the home or workplace is often the source of unintentional exposures. Standards and Guidelines OSHA PEL (permissible exposure limit) = 0.1 mg/m³ (vapor) (ceiling) NIOSH IDLH (immediately dangerous to life or health) = 10 mg/m³ Physical Properties Description: Liquid is shiny, silvery-white, and heavy; vapor is colorless and odorless. Warning properties: Odor is inadequate to warn of toxic exposure. Molecular weight: 200.59 daltons Boiling point (760 mm Hg): 674ºF (356.72ºC) Freezing point: -102ºF (-38.9ºC) Specific gravity: 13.6 at 77ºF (25ºC) (water = 1.00) Vapor pressure: 0.002 mm Hg at 77ºF (25ºC) [Note: Although the vapor pressure of elemental mercury is low, at 24ºC, an atmosphere that is fully saturated with mercury vapor contains approximately 18 mg/m³. The levels attainable in indoor airs at room temperature can therefore greatly exceed safe levels and result in poisoning.] Gas density: 6.9 (air = 1) Water solubility: 0.006% at 77ºF (25ºC) Flammability: Nonflammable Incompatibilities Elemental mercury reacts vigorously with ground mixtures of sodium carbide, aluminum, lead, or iron. A violent exothermic reaction, possibly an explosion, occurs when mercury comes in contact with chlorine dioxide, lithium, or rubidium. It also reacts with acetylenic compounds, ammonia, azides, boron diiodophosphide, ethylene oxide, methyl azide, methylsilane, oxygen, oxidants, and tetracarbonylnickel. Pure dry ammonia and mercury do not react even under pressure and heat, but if water is present, a compound forms that can explode during depressurization. Heating mercury vapor produces mercuric oxide, which is highly irritating to mucous membranes and more likely than elemental mercury vapor to cause chemical pneumonitis. top Health Effects The major route of exposure to elemental mercury is inhalation of mercury vapor. Symptoms of acute toxicity following high-level exposure to mercury vapor occur within hours of the exposure. Respiratory symptoms include corrosive bronchitis with fever chills and dyspnea, which can progress to pulmonary edema or fibrosis. Abdominal cramps, diarrhea, renal dysfunction, visual disturbances, and central nervous system damage leading to neuropsychiatric disturbances and intention tremors may also occur. Mercury can cross the blood-brain and placental barriers. It is also excreted in breast milk. Children may be at increased risk for pulmonary toxicity and are more likely to develop respiratory failure. Acute Exposure Many acute health effects are associated with exposure to high levels of elemental mercury vapor. Respiratory symptoms may predominate (cough, sore throat, shortness of breath). Gastrointestinal effects are frequent in the initial set of symptoms (metallic taste, nausea, vomiting, diarrhea, abdominal pain) as are CNS effects such as headache, weakness, and visual disturbances. Several days after the initial exposure, symptoms are more similar to those that develop following inorganic mercury poisoning, including ptyalism (heavy salivation), enteritis, and renal damage; there can also be chronic CNS effects, which develop as a result of the ability of absorbed elemental mercury to cross the blood-brain barrier. Children do not always respond to chemicals in the same way that adults do. Different protocols for managing their care may be needed. Respiratory Acute exposure to high levels of elemental mercury vapor can cause chemical pneumonitis. Within a few hours of exposure, dyspnea, chest pain, and dry cough develop, often associated with fever, chills, and headache. Symptoms might resolve or gradually progress to pulmonary edema, respiratory failure, and death. The acute mercury-induced lung damage usually resolves completely, but some cases of diffuse pulmonary fibrosis, restrictive lung disease, and chronic respiratory insufficiency have been reported. At autopsy, microscopic examination of lung tissue reveals interstitial pneumonitis, necrotizing bronchitis, bronchiolitis, and atelectasis. Children may be more vulnerable to gas exposure because of relatively increased minute ventilation per kg and failure to evacuate an area promptly when exposed. Renal Acute high-dose inhalation of elemental mercury vapor has been associated with proteinuria, nephrotic syndrome, temporary tubular dysfunction, acute tubular necrosis, and oliguric renal failure. Cardiovascular Acute inhalation of high levels of elemental mercury vapor can cause tachycardia and hypertension. In children, tachycardia associated with the inhalation of elemental mercury vapor might be related to a non-allergenic hypersensitivity reaction to mercury. Gastrointestinal A metallic taste, salivation, dysphagia, abdominal cramps, diarrhea, and nausea have been reported following inhalation of large amounts of elemental mercury vapor. Oral and dermal exposures to elemental mercury are not normally associated with GI symptoms. Dermal Dermal reactions associated with dermal contact with liquid elemental mercury or the vapor are rare. Acrodynia (or pink disease) is associated with hypersensitivity to mercury absorbed from vapor inhalation or dermal exposure. Symptoms of acrodynia include abnormal redness of the skin, followed by peeling of skin on the hands, nose, and soles of the feet. CNS Acute inhalation of mercury vapor may produce CNS effects such as headache, weakness, and visual disturbances. Potential Sequelae Respiratory effects from high-dose acute exposures might resolve or gradually progress to adult respiratory distress syndrome (ARDS), respiratory failure, and death. Patients with severe pulmonary toxicity can develop interstitial fibrosis and residual restrictive pulmonary disease. Other sequelae of exposure to elemental mercury include effects on the CNS and kidneys. These can occur after high-dose acute inhalation exposure and are similar to the effects observed following chronic lower-dose exposures (see bel
