IDENTIFICATION AND USE: Lead dioxide is a dark-brown powder. It is used in electrodes in batteries; as oxidizing agent in manufacture dyes; as discharge in dyeing with indigo; manufacture rubber substitutes; with amorphous phosphorus as ignition surface for matches; pyrotechnics; manufacture pigments; in analytical chemistry. HUMAN EXPOSURE AND TOXICITY: Exposure can cause headache, irritability, and muscle and joint pain. Lead dioxide may damage the nervous system. Exposure may cause kidney and brain damage, and anemia. Repeated exposure to lead dioxide can cause lead poisoning. Symptoms include metallic taste, poor appetite, weight loss, colic, nausea, vomiting, and muscle cramps. Higher levels can cause muscle and joint pain, and weakness. High or repeated exposure may damage the nerves causing weakness, "pins and needles," and poor coordination in the arms and legs. Lead exposure increases the risk of high blood pressure. ANIMAL STUDIES: There are no data available.

Lead(IV) dioxide occurs in nature as the mineral plattnerite(1). A plattnerite mineral sample from the Ojuela mine in Mexico assayed PbO2 99.6% and CuO 0.1%(2). Plattnerite occurs in weathered hydrothermal base-metal deposits, oxidized typically in arid climates(2). In the US, large plattnerite masses occur from the Coeur d'Alene district, Shoshone Co., and in the Democrat mine, Gilmore district, Lemhi Co., Idaho; from the Goodsprings district, Clark Co., and the Diamond mine, near Eureka, Eureka Co., Nevada. In the 79 mine, Gila Co., the Defiance mine, Gleeson, Cochise Co., the Glove mine, Santa Cruz Co., and elsewhere in Arizona; at the Mex-Tex mine, near Bingham, Hansonburg district, Socorro Co., and Granite Gap, San Simon district, Hidalgo Co., New Mexico(2).

Lead(IV) dioxide's production and use in the manufacture of electrodes for lead-acid batteries and in the manufacture of dyes, chemicals, matches, pyrotechnics, and liquid polysulfide elastomers(1,2) may result in its release to the environment through various waste streams(SRC). Lead oxides (monoxide, dioxide, tetroxide) may also be formed when lead is heated to high temperatures in the presence of oxygen(3,4). Therefore smelting and refining of lead as well as welding and soldering are potential sources of lead(IV) dioxide emissions(SRC).|Lead(IV) dioxide solids (PbO2) can form as constituents of scales of lead corrosion products that develop in lead pipes via oxidation-reduction potential induced by residual free chlorine which can effect drinking water distribution systems(1). The natural formation of PbO2 in lead service lines for water distribution is a "corrosion" control occurrence(2).[(1) Wang Y et al; Lead(IV) Oxide Formation and Stability in Drinking Water Distribution Systems|Lead in urban air occurs as ... lead dioxide particles derived from tetraethyl /Lead/ ...

TERRESTRIAL FATE: Lead(IV) dioxide is not expected to leach in soil because of its low solubility(SRC). The downward movement of inorganic lead compounds from soil to groundwater by leaching is very slow under most natural conditions(1).|AQUATIC FATE: If released into water, lead(IV) dioxide should mostly precipitate out due to its low solubility. (SRC)|ATMOSPHERIC FATE: In the atmosphere, non-organic compounds of lead exist primarily in the particulate form and, therefore, lead(IV) dioxide is expected to exist solely in the particulate phase in the ambient atmosphere. Upon release to the atmosphere, lead particles are dispersed and ultimately removed from the atmosphere by wet or dry deposition(1).

Bioaccumulation of lead(IV) dioxide may occur in plants and in mammals(1).

The downward movement of inorganic lead compounds from soil to groundwater by leaching is very slow under most natural conditions(1). /Lead compounds/

Evaporation of lead(IV) dioxide at 20 °C is negligible(1).

According to the 2012 TSCA Inventory Update Reporting data, 5 reporting facilities estimate the number of persons reasonably likely to be exposed during the manufacturing, processing, or use of lead(IV) dioxide (1309-60-0) in the United States may be as low as 10-24 workers and as high as 500-999 workers per plant; the data may be greatly underestimated due to confidential business information (CBI) or unknown values(1).|Occupational exposure to lead(IV) dioxide may occur through inhalation and dermal contact with this compound at workplaces where lead(IV) dioxide is produced or used. Use data indicate that the general population may be exposed to lead(IV) dioxide via dermal contact with consumer products containing lead(IV) dioxide(SRC). Lead(IV) dioxide solids (PbO2) can form as constituents of scales of lead corrosion products that develop in lead pipes via oxidation-reduction potential induced by residual free chlorine which can effect drinking water distribution systems(1). Therefore, the general population may be exposed to lead(IV) dioxide via ingestion of drinking water coming from pipes containing lead that have been exposed to chlorination processes(SRC).[(1) Wang Y et al; Lead(IV) Oxide Formation and Stability in Drinking Water Distribution Systems

This solubility was studied in vitro for the six following metal oxides: Cd, Cr, Fe, Mn, Pb, Zn, by holding particle oxides in suspension into human plasma at 37 degrees C, during variable time. The experimentation was realized on particles which belong to two categories which sizes are 0.45-2 and 2-5 mu. The evolution of metal oxide dissolved level according to time have enabled exponential relation parameters to be calculated. These parameters translate the particle oxide dissolution into plasma and have permitted to classify metal oxide in decreasing solubility order: Cd, Zn, PbO, Fe2O3, Fe3O4, Mn, PbO2, Pb3O4 and Cr2O3.

IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: Some heavy metals are VERY TOXIC POISONS, especially if their salts are very soluble in water (e.g., lead, chromium, mercury, bismuth, osmium, and arsenic). IMMEDIATELY call a hospital or poison control center and locate activated charcoal, egg whites, or milk in case the medical advisor recommends administering one of them. Also locate Ipecac syrup or a glass of salt water in case the medical advisor recommends inducing vomiting. Usually, this is NOT RECOMMENDED outside of a physician's care. If advice from a physician is not readily available and the victim is conscious and not convulsing, give the victim a glass of activated charcoal slurry in water or, if this is not available, a glass of milk, or beaten egg whites and IMMEDIATELY transport victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, assure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. OTHER: Since this chemical is a known or suspected carcinogen you should contact a physician for advice regarding the possible long term health effects and potential recommendation for medical monitoring. Recommendations from the physician will depend upon the specific compound, its chemical, physical and toxicity properties, the exposure level, length of exposure, and the route of exposure.
