the first source of emissions is calcination, which decomposes quarried limestone (calcium carbonate) into quicklime (calcium oxide) and releases co 2 as a by-product. the second source is the heat needed to achieve calcination, which requires temperatures over 2700°f (1500°c), or almost one-third the surface temperature of the sun.

in a university library, activities typical of librarians, such as unpacking boxes, removing books from the shelves, dusting, packing boxes, cataloguing, conservation and repair, photocopying, setting materials for class, and walking in a main hallway, were found to reduce indoor air quality through the production of airborne mold spores, metal dusts, and particulate matter of different size bins.
on some we find hard shells made of calcium carbonate. on others, a glass-like material. this gives protists such as diatoms, foraminifera, and radiolarians a unique, even ornamental appearance.
this is in large part owing to the reliance of coral reefs on the capacity of corals and other calcifiers to produce calcium carbonate through the process of calcification, and existing calcareous structures’ resistance to the process of dissolution, both of which are subject to negative impacts from changing carbonate chemistry conditions associated with oa (andersson et al., 2011, ipcc, 2014).
