Barium is a chemical element; it has symbol Ba and atomic number 56. ... Barium sulfate has a low toxicity and relatively high density of ca. 4.5 g/cm 3 ...
Barium acetate (Ba(C 2 H 3 O 2) 2) is the salt of barium(II) and acetic acid. Barium acetate is toxic to humans, but it has use in chemistry and manufacturing. Barium acetate is toxic to humans, but it has use in chemistry and manufacturing.
[4] [5] This phenomenon of poison shyness is the rationale for poisons that kill only after multiple doses. Besides being directly toxic to the mammals that ingest them, including dogs, cats, and humans, many rodenticides present a secondary poisoning risk to animals that hunt or scavenge the dead corpses of rats.

Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation. [8] Solutions of sulfate salts such as Epsom salts or sodium sulfate may be given as first aid for barium poisoning, as they precipitate the barium as the insoluble (and non-toxic) barium sulfate. Inhalation may also cause irritation to the respiratory tract.
Marie stole barium acetate from her high school chemistry class and laced her father's tacos with a lethal dose. The trial received media attention since she was a promising student, and patricide is a rare crime more commonly committed by men.
The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2] Cleanup costs may exceed $1.2 billion. [3] A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4]
Barium oxide, also known as baria, is a white hygroscopic non-flammable compound with the formula BaO. It has a cubic structure and is used in cathode-ray tubes , crown glass, and catalysts. It is harmful to human skin and if swallowed in large quantity causes irritation.
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]
