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.
Highly toxic to humans in its elemental form. [11] iridium: 77: 1a: Due to its extreme rarity, iridium has no biological role. [11] The chloride is moderately toxic to humans. [11] iron: 26: 5: Essential to almost all living things, usually as a ligand in a protein; it is most familiar as an essential element in the protein hemoglobin. [11 ...
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
In Australia, bromomethane is the preferred fumigant of the Department of Agriculture and Water Resources for most organic goods imported into Australia. [13] The department conducts methyl bromide fumigation certification for both domestic and foreign fumigators who can then fumigate containers destined for Australia.
Just how common that is varies widely: Anywhere from 10% to 78% of samples of bottled water have been found to contain contaminants that may be harmful to human health. They include:
Human tissue contains approximately 0.2 to 0.5% chlorine. There is a total of 95 grams of chlorine in a typical 70-kilogram human. [7] Some bromine in the form of the bromide anion is present in all organisms. A biological role for bromine in humans has not been proven, but some organisms contain organobromine compounds. Humans typically ...
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disorder, being responsible for 5 to 10% of psychiatric hospital admissions, but is now uncommon since bromide was withdrawn from clinical use in ...
The FDA said it banned brominated vegetable oil after "the results of studies conducted in collaboration with the National Institutes of Health (NIH) found the potential for adverse health effects ...
