Small quantities. Wear nitrile rubber gloves, laboratory coat, and eye protection. Avoid breathing dust. Dissolve the barium salt in the minimum volume of water. For each gram of barium salt, add 15 mL of 10% sodium sulfate solution. Let stand for 1 week. Test for completeness of precipitation by adding a few drops of 10% sodium sulfate solution. If required, add more sodium sulfate solution until no further precipitation occurs. Decant supernatant liquid or filter solid. Treat solid as normal refuse. Wash liquid into drain. /Barium salt/

누출 처리	Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.

Preventive Measures

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.If 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. Do not use water.Personnel protection: Avoid breathing vapors. Keep upwind ... Avoid bodily contact with the material ... Do not handle broken packages unless wearing appropriate personal protective equipment.

건강 영향

The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea, paralysisand possibly death. Barium may also cause gastrointestinal disturbances, damage the kidneys and cause decreases in body weight. (L214)

독성 요약

IDENTIFICATION: In nature barium occurs in a combined state, the principal forms being barite (barium sulfate) and witherite (barium carbonate). Barium carbonate has a very low water solubility. Barium and its compounds are used in diverse industrial products ranging from ceramics to lubricants. It is used in the manufacture of alloys, as a loader for paper, soap, rubber and linoleum, in the manufacture of valves and as an extinguisher for radium, uranium and plutonium fires. Anthropogenic sources of barium are primarily industrial. Emissions may result from mining, refining or processing barium minerals and the manufacture of barium products. Mining and processing of barite ore releases particulates into the air and from fugitive dists from the use of barite in oil drilling and oil related industries. HUMAN EXPOSURE: It is difficult to assess the uptake of ingested barium because of a number of factors affect absorption. ANIMAL/PLANT STUDIES: Insoluble barium compounds such as barium carbonate, accumulate in the lungs and are cleared slowly ciliary action. Oral or inhalation administration of barium carbonate in rats resulted in adverse reproductive effects. In addition, the death rate was higher in the new born offspring of barium treated dams.Barium is a competitive potassium channel antagonist that blocks the passive efflux of intracellular potassium, resulting in a shift of potassium from extracellular to intracellular compartments. The intracellular translocation of potassium results in a decreased resting membrane potential, making the muscle fibers electrically unexcitable and causing paralysis. Some of these barium's effects may also be due to barium induced neuromuscular blockade and membrane depolarization. (L214)

생태독성 발췌

/AQUATIC SPECIES/ Very limited data are available on the toxicity of barium carbonate to aquatic species, but in natural fresh and marine waters the presence of sulfate ions will limit the availability of the barium ion, which is the toxic moiety of most barium salts. Ba++, dissociated from the carbonate salt, will precipitate with sulfate ions to insoluble BaSO4./OTHER TERRESTRIAL SPECIES/ No specific data are available, but due to the ubiquitous presence of barium (mostly as the sulfate or carbonate salt) in soil, the toxicity of barium carbonate to soil dwelling organisms is not deemed of particular concern./FIELD STUDIES/ In December 2003, the USEPA released an amended list of 15 "candidate pollutants for exposure and hazard screening" with regard to biosolids land application, including Ba. Therefore, /it was/ decided to monitor soil Ba concentrations from a dryland wheat (Triticum aestivum L.)-fallow agroecosystem experiment. This experiment received 10 biennial biosolids applications (1982-2003) at rates from 0 to 26.8 dry Mg/ha per application year. The study was conducted on a Platner loam (Aridic Paleustoll), approximately 30 km east of Brighton, CO. Total soil Ba ... increased with increasing biosolids application rate. In the soil-extraction data from 1988 to 2003, however, we observed significant (P < 0.10) linear or exponential declines in ammonium bicarbonate-diethylenetriaminepentaacetic acid (AB-DTPA) extractable Ba concentrations as a function of increasing biosolids application rates. This was observed in 6 of 7 and 3 of 7 yr for the 0- to 20- and 20- to 60-cm soil depths, respectively. Results suggest that while total soil Ba increased as a result of biosolids application with time, the mineral form of Ba was present in forms not extractable with AB-DTPA. ... /This/ research showed that biosolids application may increase total soil Ba, but soil Ba precipitates are insoluble and should not be an environmental concern in similar soils under similar climatic and management conditions.

Signs and Symptoms	Cough. Sore throat.Redness.Nausea. Vomiting. Abdominal cramps. Diarrhoea. Weakness.Ingesting excess barium may cause vomiting, abdominal cramps, diarrhea, difficulties in breathing, increased or decreased blood pressure, numbness around the face, and muscle weakness. High levels may result in changes in heart rhythm or paralysis and possibly death. (L214)

Natural Pollution Sources	Barium is a naturally occurring element found in the earth's crust(1) that enters the environment through the weathering of rocks and minerals(SRC). The principal barium minerals are barite (barium sulfate) and witherite (barium carbonate)(1).Ores of ... witherite are found in Georgia, Missouri, Arkansas, Kentucky, California, Nevada, Canada, Mexico.

Human Toxicity Excerpts

/SIGNS AND SYMPTOMS/ Most patients with barium intoxication have gastrointestinal and cardiac involvement with tetraplegia. Barium carbonate is a rare cause of hypokalemic periodic paralysis. Diarrhea and arrhythmias are due to direct stimulatory action of barium ions on smooth and cardiac muscles. Heart failure and hypertension may occur in a few cases. Barium blocks the potassium channels and thus potassium efflux from the muscle is reduced whereas the sodium-potassium pump is intact. This causes increased potassium in the muscle and decreased resting membrane potential. Barium acts mainly at the neuromuscular junction by this mechanism. The fatal dose of barium carbonate is 0.8 g and death occurs within 2 to 12 hours./SIGNS AND SYMPTOMS/ There are a number of reports of serious health effects in individuals intentionally or accidentally exposed to barium carbonate... . The predominant effect is hypokalemia, which can result in ventricular tachycardia, hypertension and/or hypotension, muscle weakness, and paralysis ... In addition to the effects associated with hypokalemia, gastrointestinal effects such as vomiting, abdominal cramps, and watery diarrhea are typically reported shortly after ingestion./SIGNS AND SYMPTOMS/ Potential symptoms of overexposure are excessive salivation, vomiting, severe abdominal pain, violent diarrheaincreased blood pressuretinnitis, giddiness, vertigomuscle twitching, convulsions, paralysisdilated pupilsconfusion, somnolencecardiac arrestdeath due to respiratory failure./SIGNS AND SYMPTOMS/ ... A benign pneumoconiosis (baritosis) may result from inhalation of ... barium carbonate. It is not incapacitating and is usually reversible with cessation of exposure.For more Human Toxicity Excerpts (Complete) data for Barium carbonate (24 total), please visit the HSDB record page.

Non-Human Toxicity Excerpts

/LABORATORY ANIMALS: Acute Exposure/ In inhalation studies in guinea pigs/ ... collected particulate material from fumes generated by manual arc-welding (with electrodes using barium fluoride or carbonate) was extracted with dilute hydrochloric acid to give a solution containing barium. Aerosols generated from the barium fume extract were inhaled intratracheally by mechanical ventilation and were found to cause bronchoconstriction to the same extent as the inhalation of pure barium chloride (90 ug/cu m/min)./LABORATORY ANIMALS: Acute Exposure/ After IV injection, GI symptoms are less marked /than after oral administration, the/ most distinctive feature being slowing of heart.
