[edit] Flame color

What is the color do barium compounds impart to fireworks? Should be the same as its flame test color, right? (which I don't remember what is). RJFJR 17:14, Feb 18, 2005 (UTC)

Found it: green. RJFJR 05:17, Feb 19, 2005 (UTC)

[edit] Ba-137 is stable?

Are we sure this is right? Because if it is, I think I just spend twenty minutes of my day watching a stable isotope decay... but I can't find any other information to support this. (It had a half life of about 2m40s, incidentally.) —The preceding unsigned comment was added by 68.198.14.124 (talk • contribs) 00:56, 5 May 2005 (UTC).

You were witnessing the decay of a metastable isomeric state, the half-life value agrees quite well with that (see isotopes of barium). Femto 13:23, 27 January 2006 (UTC)

What is the most common isotope of barium? —The preceding unsigned comment was added by 68.186.102.204 (talk • contribs) .

See the natural abundance (NA) in the isotope table of the infobox. Femto 13:12, 8 February 2006 (UTC)

[edit] Bioaccumulate

Is this a heavy metal that bioaccumulates like Lead and Mercury? —The preceding unsigned comment was added by 12.41.204.3 (talk • contribs) 20:48, 26 January 2006 (UTC).

According to [1]: "[Barium does] not bioaccumulate, and concentrations in higher species rarely exceed 10 mg/kg." citing J.W. Moore, Inorganic Contaminants of Surface Waters, Research and Monitoring Priorities. Springer-Verlag, New York. (1991). Femto 13:23, 27 January 2006 (UTC)

[edit] Barite or baryte

The sulfate can be spelled barite (American) or baryte (British). Which one? I changed all mentions to barite for now as this is the title of the article.
