Elemental bromine (Br 2) is toxic and causes chemical burns on human flesh. Inhaling bromine gas results in similar irritation of the respiratory tract, causing coughing, choking, shortness of breath, and death if inhaled in large enough amounts. Chronic exposure may lead to frequent bronchial infections and a general deterioration of health.
Bromism is the syndrome which results from the long-term consumption of bromine, usually through bromine-based sedatives such as potassium bromide and lithium bromide. Bromism was once a very common disorder, being responsible for 5 to 10% of psychiatric hospital admissions, but is now uncommon since bromide was withdrawn from clinical use in ...
Serious poisoning happens more frequently in domestic animals, which metabolize theobromine much more slowly than humans, [7] and can easily consume enough chocolate to cause poisoning. The most common victims of theobromine poisoning are dogs, [8] [9] for whom it can be fatal. The toxic dose for cats is even lower than for dogs. [10]
Megan Liu, lead study author and science and policy manager at Toxic-Free Future, tells Yahoo Life that this was a “minor point” in the study. “We feel bad that this happened,” she adds.
Theobromine has no significant stimulant effect on the human central nervous system. [4] It is a bronchodilator and causes relaxation of vascular smooth muscle. [4] It is not currently used as a prescription drug. [5] The amount of theobromine found in chocolate is small enough that chocolate can, in general, be safely consumed by humans.
A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
