A bit of wishful thinking that's more suited for WhatsApp University.
Plants and trees cannot absorb pollutants through air, like they definitely do from the soil along with absorbed water, and other nutrients.
The only thing I know of that plants absorb directly from air is CO2, which is not a pollutant in the present concentration levels in the atmosphere at 0.04% or about 400 parts per million. There is enough research that shows the earth had periods of much higher CO2 concentration - 2x to 3x and even more without the oceans boiling away to heavens.
What plants do is act as physical barriers and filters against dust particles and pollutants suspended in air. Which is good enough reason to increase green cover and plants in urban areas.
