What gases are produced from quarrying?

Quarrying operations primarily produce dust and particulate matter, but they can also release gases such as carbon dioxide (CO2) and methane (CH4) during the extraction and processing of rocks. The combustion of fossil fuels used in machinery can contribute to emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2). Additionally, the use of explosives can release gases like carbon monoxide (CO) and volatile organic compounds (VOCs). Overall, while the focus is often on particulate emissions, various gases can be generated throughout the quarrying process.
