Tainted Chinese Drywall

Strontium is a relatively plentiful element on Earth. Strontium-containing minerals that are found in gypsum are strontianite (strontium carbonate) and celestite (strontium sulfate). Yet, strontium is not only found in gypsum.
Major Inorganic Constituents of Water

Sources of strontium (Sr2+) are strontianite (SrCO3), celestite (SrSO4), and aragonite (CaCO3). The latter is probably the most common source because Sr2+ substitutes for Ca2+ in aragonite, but not in calcite. Thus, during diagenesis when aragonite is converted to the more stable polymorph calcite, the strontium is released to the water. The common sinks are the minerals strontianite and celestite, although ion exchange is probably more important. Strontium may occur in the 100–1000-mg/l range in oil-field brines. It has been reported in these waters as high as 11,600 mg/l (Collins, 1975). Seawater contains 8 mg/l Sr.

Strontium occurs commonly as the mineral celestite, and less commonly as the mineral strontianite. Both of these minerals form as chemical sediments, and thus are associated with sedimentary rocks such as limestone, dolostone, and evaporites. At the dolostone quarry near Haley, the celestite occurs in a different form: as slab-like masses of radiated, columnar, or fibrous crystals surrounded by dolomite (Dawson 1985). Because of the association with dolostone and limestone, strontium is mined along with calcium and magnesium derived from the dolomite and calcite minerals.

A relatively rare calcium carbonate mineral, strontianite occurs as nodules in limestone. As a pigment it appears to be mentioned as trace component of calcium sulfate evaporite deposits of gypsum and anhydrite (Eastaugh et al. 2008). Previous studies carried on Roman mural paintings (Paternoster et al. 2005) identified strontianite mineral in the pictorial and preparation layer, suggesting the idea that it is a part of the original compounds that have been used to lay the pigments. Previous studies on plasters coming from a fresco from the first century (Sciuti et al. 2001), have also shown that the presence of strontium sulfate is not uncommon for Roman wall paintings.
