How do you think pollutants are removed from the atmosphere? does this occur quickly or slowly?

A tree is able to remove air pollution via its leaves in two ways. The first is by direct uptake through the leaves in 2 ways ... The amount of pollution removal was calculated for ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and particulate matter less than ten microns (PM10).

Maybe a couple days to a week.
