Open-pit mining involves the process of disrupting the ground, which leads to the creation of air pollutants. The main source of air pollutants comes from the transportation of minerals, but there are various other factors including drilling, blasting and the loading and unloading of overburden.<ref name=impact>{{Cite journal |last1=Huertas |first1=José I. |last2=Huertas |first2=María E. |last3=Izquierdo |first3=Sebastián |last4=González |first4=Enrique D. |title=Air quality impact assessment of multiple open pit coal mines in northern Colombia |journal=Journal of Environmental Management |volume=93 |issue=1 |pages=121–129 |date=January 2012 |pmid=22054578 |doi=10.1016/j.jenvman.2011.08.007}}</ref> These type of pollutants cause significant damage to public health and safety in addition to damaging the air quality. The inhalation of these pollutants can cause issues to the lungs and ultimately increase mortality.<ref name=impact /> Furthermore, the pollutants affect flora and fauna in the areas surrounding open-pit mines.
Open-pit gold mining is one of the highest potential mining threats on the environment as it affects the air and water chemistry. The exposed dust may be toxic or radioactive, making it a health concern for the workers and the surrounding communities.<ref>{{Cite journal|last1=Abdul-Wahab|first1=Sabah|last2=Marikar|first2=Fouzul|date=2012-01-01|title=The environmental impact of gold mines: pollution by heavy metals|journal=Open Engineering|volume=2|issue=2|page=304|doi=10.2478/s13531-011-0052-3|bibcode=2012CEJE....2..304A|s2cid=3916088|issn=2391-5439|doi-access=free}}</ref>
