  • Other scientists, however, have called into question the experimental designs of such studies, citing inconsistent results specifically in studies used to test DNA damage.

  • Firstly, calcium carbonate factories can be categorized into two primary types natural and synthetic. Natural calcium carbonate factories extract limestone, marble, or chalk, all of which are rich in calcium carbonate, from the earth's crust. These materials are then processed through grinding and purification techniques to produce calcium carbonate powder. On the other hand, synthetic calcium carbonate factories create the compound through a chemical reaction between calcium oxide (quicklime) and carbon dioxide. This method is often used when a purer form of calcium carbonate is required.
