Үнэ авахThis effect again has to do with the formation of their coccoliths and the chemical reaction involved in the process. The chemical reaction that makes the coccolith also generates a carbon dioxide molecule, a potent greenhouse gas, from the oxygen and carbon already in the ocean. While much of the gas is sucked back in by the coccoliths (all plants take in carbon dioxide for food) some of it. Assessment of Environmental Impacts of Limestone QuarryingDiesel fuel and electricity consumption in the mining processes were the main causes of those impacts. For climate change, the unit of CO 2 eq. was expressed to quantify the total GHGs emissions. Estimated result was about kg CO 2 eq. per ton limestone rock product.
