The World Health Organization's safe air quality criteria are routinely exceeded in Patna, raising concerns about the city's air quality. Nonetheless, the Patna Metro project's use of mist spray dust suppression technology has the potential to drastically reduce the city's AQI. It would allay the worries of locals about dust pollution near construction sites and is the perfect solution for towns like Patna where air pollution is a major problem.

Even in the worst circumstances, mist spray technology has been demonstrated to be efficient at reducing dust pollution. Together with maintaining the area's cleanliness, it lowers the possibility that neighbouring residents and workers will experience respiratory issues. As required by the Air (Prevention and Control of Pollution) Act of 1981, DMRC assures the application of environmental best practises for limiting emissions or reducing the environmental effect of building activities.

By 2026, when construction on the Patna Metro is anticipated to be finished, locals will have much-needed transportation options. Residents may rest easy knowing that the project will be completed with the highest consideration for the environment and their health thanks to the deployment of mist spray dust suppression technology.
