Very interesting, especially “
Ba.
Coral skeletons from Phuket, Thailand, contain 6 to 18 µg/g barium, compared to 14 to
2,300 µg/g dry wt in soft tissues of the same species (Howard and Brown, 1986).
Aragonitic skeletons of some stony corals contain up to 450 µg/g barium (Bowen, 1956).
Thus, carbonate sediments derived from calcitic skeletal materials usually contain low
concentrations of barium, whereas coral sands often contain high barium concentrations.
Barium tends to co-precipitate with strontium in the celestite (SrSO4) skeletons of plank-
tonic acantharians, influencing the fluxes of dissolved and particulate barium to the deep
ocean (Bernstein et al., 1998). Deep-sea sediments often contain elevated concentrations
of strontium and barium from this source. Clay-rich shales also may contain high con-
centrations of barium (Trefry, 1982)“
That explains why triton guess that strontium additions could be contaminated yet it’s their product I use , note…. I’ve only dosed this for the last month and had prior barium levels also at 100ugl
Definitely seems nothing to worry about given coral tissue had either 450 or 2300ugl depending on whether it’s an argonite coral ( help please boss)
