RATS, MICE, & RABBITS INHALING 0.2 PPM OF BROMINE FOR 4 MONTHS DEVELOPED DISTURBANCES IN THE FUNCTIONS OF THEIR RESPIRATORY, NERVOUS, & ENDOCRINE SYSTEMS; 0.02 PPM DID NOT CAUSE ANY ADVERSE EFFECTS.
Immediate & delayed (24 hr) effects of a 20 min exposure of cowpea primary leaf tissue to 1, 3, or 5 ppm bromine gas was studied. The formation of circular, adaxial & abaxial surface lesions & leaf compression were the most visible changes. At 1 ppm cellular changes such as adaxial depression & anticlinal cell wall interdigitation were reversed when exposed plants were returned to normal environment. At 5 ppm the entire population immediately became irreversibly necrotic.
Concentrations of more than 30 mmol/l (2400 mg/l) bromide in serum of cattle led to signs of motor incoordination.
Bromine releases as a consequence of ... production activities has had serious effects upon vegetation in the locale. The first noted manifestation of a problem was damage to coniferous trees near the bromine plants. Needle tip necrosis after 13 to 14 month and 1 to 2 month exposure times was very evident within a 3 mile radius of all bromine facilities sampled. At further distances of 3.5 to 12 miles, tip damage was sporadic, varying from tree to tree, and not evident on 1 to 2 month-exposure needles. The foliage burn and death of trees within 0.5 to 1 mile was extreme. Conifers were decidedly more susceptible to the bromine emissions than were broadleaf trees, shrubs, and grasses. Chlorophyll (a and b) levels were greatly reduced in the conifer trees surrounding the bromine plants. This was taken as a strong indicator of extreme air pollution problems because chlorophyll does not reflect environmental problems until they become overwhelming.
Animal studies have shown that 3-hr exposures to bromine at 3 ppm can result in pulmonary edema and direct damage to the airway epithelia.
Approximately 50% of mice exposed to bromine at 240 ppm for 2 hr died within 30 days after the exposure. At 750 ppm, a 7-min exposure of mice was lethal to approximately 40% within 30 days after the exposure.

Natural Pollution Sources:
ABUNDANCE IN IGNEOUS ROCK: 1.6X10-4% BY WT; IN SEAWATER 0.0065% BY WT.
It does not occur in nature in pure form because of its high reactivity but is found as a normal secondary component of chlorine in minerals and biological systems. A pure bromine-containing mineral is found in Mexico as bromite (AgBr).
Artificial Pollution Sources:
Traces of bromine & lead were detected in air from automobile exhaust gases.
Environmental Fate:
Studies on the determination of avg contents of bromine in soils & plants of Japan, forests of the Andosol region of Central Honshu were evaluated. The avg content of bromine in soils of grasslands, orchards & upland crop fields were 10 fold higher than those recorded from overseas. The avg content in these soils was higher than those recorded in forest soil of the basins of the Miomote & Nagara Rivers (Japan). The avg values reported in the leaves of plants in Miomote & Nagara Rivers was 12 ppm. The contents of iodine & bromine in the forest soil, plants & rainwater were generally higher in coastal than in the inland areas.
The contents of three elements in the soils & plants were evaluated with emphasis placed on the difference of the land utilization in the basin of the Nagara River. The avg content of bromine in soils of the forest from the basin of the Nagara River was almost 10 fold higher than those reported outside of Japan (63 ppm). This was similar to avg level found in the Miomote River. In paddy soils, the bromine content was more than 10 times lower than in the former (plow layer; 3.3 ppm). These findings were ascribed to the eluviation of iodine & bromine from the soil under submerged conditions. The concn factor (content in plant leaves/content in soil surface (horizon A or plow layer) /in dry wt basis/, for wild plants was 0.10 ppm; in paddy rice, 6.2 ppm.
The contents of the three elements were evaluated according to land utilization in the basin of the Miomote River. The avg contents of bromine in soils of the forest & upland fields were almost 10 times higher than those recorded from overseas. In paddy soils bromine content was more than 10 times lower (plow layer; 7.0 ppm) than in former. These findings were ascribed to the eluviation of iodine & bromine from the soil under submerged conditions. The concentration factor in wild plants (content in leaves of plant per dry wt/content in horizon-A of soil,/on dry wt basis/ was 0.37.
Environmental Water Concentrations:
Searles Lake in CA is reported to contain 0.085% bromide, other sources are brine wells the richest are found in Arkansas & Michigan. /Bromine/
Dead Sea is estimated to contain 1 billion tons of bromine; seawater contains about 65 ppm bromine; underground water content in Poland has an estimated 36 million tons of bromine.
Atmospheric Concentrations:
In an abnormal urban atmospheric situation, an exceptionally increased lead concentration which had no relationship to traffic modification was found. Other sources were detected by using simultaneous studies of granulometric distribution & concentrations of lead & bromine.
Lead & bromine particles were detected in air from automobile exhaust gases. The particulates were produced by the internal combustion engine which used leaded premium gasoline.
Environmental Standards & Regulations:
FIFRA Requirements:
The food additives, bromide ion and residual bromine, may be present in potable water in accordance with the following conditions: (a) The food additives are present as a result of treating water aboard ships with a polybrominated ion-exchange resin (as a source of bromine) under the supervision of trained personnel, (b) Residual bromine levels are controlled to not exceed 1 ppm in the final treated water.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Bromine is found on List D. Case No: 4015; Pesticide type: Insecticide, fungicide, antimicrobial; Case Status: RED Approved 01/94; OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document .; Active ingredient (AI): Bromine; Data Call-in (DCI) Date(s): 11/15/93; AI Status: OPP has completed a Reregistration Eligibility Decision (RED) document for the case/AI.

Chemical Safety & Handling:
DOT Emergency Guidelines:
Health: TOXIC, inhalation, ingestion, or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. /Bromine; Bromine, solution/
Fire or explosion: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. /Bromine; Bromine, solution/
Public safety: CALL Emergency Response Telephone Number. ... Isolate spill or leak area immediately for at least 25 to 50 meters (80 to 160 feet) in all directions. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate enclosed areas. /Bromine; Bromine, solution/
Protective clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing which is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY, it is not effective in spill situations. /Bromine; Bromine, solution/
Evacuation: ... Fire: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. /Bromine; Bromine, solution/
Fire: Small fires: Dry chemical, CO2 or water spray. Large fires: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Fire involving tanks or car/trailer loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. /Bromine; Bromine, solution/
Spill or leak: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. /Bromine; Bromine, solution/
First aid: Move victim to fresh air. Call 911 or emergency medical service. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. /Bromine; Bromine, solution/
Initial Isolation and Protective Action Distances: Small Spills (from a small package or small leak from a large package): First, ISOLATE in all Directions 60 meters (200 feet); then, PROTECT persons Downwind during DAY 0.3 kilometers (0.2 miles) and NIGHT 1.1 kilometers (0.7 miles). LARGE SPILLS (from a large package or from many small packages): First, ISOLATE in all Directions 185 meters (600 feet); then, PROTECT persons Downwind during DAY 1.6 kilometers (1.0 miles) and NIGHT 4.0 kilometers (2.5 miles).
Odor Threshold:
ODOR THRESHOLDS OF 0.05-3.5 PPM HAVE BEEN REPORTED.
Odor low 0.329 mg/cu m; Odor high 24.5 mg/cu m
Skin, Eye and Respiratory Irritations:
Liquid /bromine/ penetrates the tissue rapidly and produces eruptions, irritations, and painful injuries which heal slowly.
Irritating concn 2.10 mg/cu m
Skin burns can occur from liquid bromine spills. Bromine initially causes a cooling effect on the skin and after a delay will produce a burning sensation that can progress to deep chemical burns as well as a brown discoloration of the skin.
Fire Potential:
Flammable in the form of liquid or vapor by spontaneous chemical reaction with reducing materials.
Fire Fighting Procedures:
Use water spray to keep fire-exposed containers cool. Use appropriate extinguishing agents on nearly combustible fires.
If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty). Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use water spray to knock-down vapors.
Hazardous Reactivities & Incompatibilities:
During bromination of acetone to bromoacetone, presence of a large excess of bromine must be avoided to prevent sudden and violent reaction.
Organic cmpd containing active hydrogen atoms adjacent to a carbonyl group (aldehydes, ketones, carboxylic acids) may react violently in unmoderated contact with bromine.
Interaction of /bromine and diethyl zinc/ without diluents may produce dangerous explosions ... .
Lithium is stable in contact with dry bromine, but heavy impact will initiate explosion, while sodium in contact with bromine needs only moderate impact for initiation. Potassium ignites in bromine vapor and explodes violently in contact with liquid bromine and rubidium ignites in bromine vapor. Aluminum, mercury, or titanium react violently with dry bromine. Warm germanium ignites in bromine vapor and antimony ignites in bromine vapor and reacts explosively with the liquid halogen. During preparation of praseodymium bromide, accidental contact of liquid bromine with small particles of praseodymium led to a violent explosion.
Interaction of silane and its homologues with bromine at ambient temperature is explosively violent.
Bromine reacts violently in contact with natural rubber, but more slowly with some synthetic rubbers.

Preventive Measures:
... IT IS BEST TO CARRY OUT LAB OPERATIONS WITH /BROMINE/ ... IN A HOOD. ACCIDENTAL CONTACT WITH SKIN MUST BE IMMEDIATELY COUNTERACTED BY WASHING WITH WATER. A WORKER WHOSE CLOTHING HAS BEEN DOUSED WITH LIQ BROMINE IS IN SEVERE DANGER UNLESS THE AFFECTED CLOTHING IS REMOVED IMMEDIATELY.
USE EFFECTIVE FUME REMOVAL DEVICE. PROTECT SKIN AGAINST EXPOSURE.
BROMINE CONCN OF 0.5 MG/CU M SHOULD NOT BE EXCEEDED ... /DURING/ PROLONGED EXPOSURE. IN ... CONCN OF 3-4 MG/CU M, WORK WITHOUT RESPIRATOR IS IMPOSSIBLE.
Contact lenses should not be worn when working with this chemical.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Personnel protection: Avoid breathing vapors. 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.
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.
Evacuation: If material leaking (not on fire) consider evqcuation of one-half (1/2) mile radius based on amount of material spilled, location and weather conditions.
If material not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Use water spray to knock-down vapors.
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet or significantly contaminated should be removed or replaced.

The International Air Transport Association (IATA) Dangerous Goods Regulations are published by the IATA Dangerous Goods Board pursuant to IATA Resolutions 618 and 619 and constitute a manual of industry carrier regulations to be followed by all IATA Member airlines when transporting hazardous materials.
The International Maritime Dangerous Goods Code lays down basic principles for transporting hazardous chemicals. Detailed recommendations for individual substances and a number of recommendations for good practice are included in the classes dealing with such substances. A general index of technical names has also been compiled. This index should always be consulted when attempting to locate the appropriate procedures to be used when shipping any substance or article.
Storage Conditions:
Store in cool, dry, well-ventilated location. Separate from oxidizing materials.
Due to the fire and explosion hazard, bromine must not be stored, transported, or treated along with acetylene, butane, methane, benzene, turpentine, or metallic powders. Vessels containing bromine and its cmpd should be kept tightly closed. Large quantities should be stored out of doors, shielded from direct exposure to sunlight, and away from areas of acute fire hazard, high-temperature processes and, readily oxidizable materials.
Cleanup Methods:
1) VENTILATE AREA OF SPILL OR LEAK. 2) COLLECT FOR RECLAMATION OR ABSORB IN VERMICULITE, DRY SAND, EARTH, OR A SIMILAR MATERIAL OR POUR SODIUM THIOSULFATE OR LIME WATER OVER SMALL SPILLS.
SOLN OR SLURRIES OF 10-50% POTASSIUM CARBONATE, 10-13% SODIUM CARBONATE, & 5-10% SODIUM BICARBONATE OR SATURATED "HYPO" SOLN (PREPARED BY DISSOLVING 4 KG OF TECHNICAL-GRADE SODIUM THIOSULFATE IN 9.5 L OF WATER & ADDING 113 G OF SODA ASH) ARE PREFERRED NEUTRALIZING AGENTS FOR LIQUID BROMINE SPILLS.
A 5% LIME SLURRY OR 5% SODIUM HYDROXIDE SOLN MAY BE USED, BUT HEATS OF REACTION ARE HIGHER FOR THESE REAGENTS. AMMONIA SOLN SHOULD NOT BE APPLIED TO LIQUID SPILLS BECAUSE OF THE HIGH HEAT OF REACTION & NITROGEN EVOLUTION. ANHYDROUS AMMONIA GAS IS USEFUL FOR NEUTRALIZATION OF BROMINE FUMES.
The maintenance of machinery and equipment is the most hazardous aspect of operations employing bromine and its cmpd. Before undertaking any such work, reaction vessels and ducting must be completely empty, carefully rinsed with water, steamed out, and purged with inert gas. Where there is spillage, water or steam should be used to clean contaminated areas. It should be strictly forbidden to have repair work carried out by one man without a standby worker. The air in the damaged equip must be checked for the presence of toxic substances before the repair work is started. If necessary, the workers have to wear gas masks after having been especially trained in their use.
Disposal Methods:
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.

Laboratory Methods:
Clinical Laboratory Methods:
Colorimetric techniques for direct quantitation of bromide in biological material are based on the property of forming complexes with gold (3+) and Palladium (2+), and the reaction to elementary bromine by oxidizing reagents. Bromine can be estimated by direct measurement of its absorption at 405 nm rosaniline or phenol red is followed. Such colorimetric methods require protein-free solutions which can be obtained by precipitation of the protein or by alkaline incineration of the organic matter, a procedure which comprises the sum of bromide and organic bound bromine.
Analytic Laboratory Methods:
AOAC Method 952.24. Carius combustion method.
AOAC Method 920.202. Manganese, Iodine, Bromine, Arsenic, and Boric Acid in Water for Preparation of Sample.
AOAC Method 974.36. Microchemical Determination of Bromine, Chlorine, or Iodine by Oxygen Flask Combustion Method.
AOAC Method 969.47. Thermoelectric-Vapor Pressure Method.
Concentrations of bromine in fish, plant, & mammalian oils were determined by cyclic instrumental neutron activation analysis. Fish oils contained 2.36-9.63 ug/g. It was not detected in rapeseed or soybean oils. In menhaden oils the bromine concn was reduced markedly by hydrogenation. The method yielded results in agreement with published values obtained by other methods. It was rapid & essentially free from interferences.
Bromine was detected in air by instrumental thermal & epithermal neutron activation analysis.
A gas chromatographic method is based on the reaction of bromine with 2,4-dimethylphenol. X-ray fluorescence and neutron activation analysis have the advantage of being highly specific, sensitive and fast, but special instrumental equipment is required. Anion exchange chromatographic determination of bromide is another highly sensitive method.
NIOSH Method 6011. Determination of Chlorine by Ion Chromatography. This method is applicable to air samples. This procedure is also applicable to bromine.
