Temporal variations of ambient air pollutants and meteorological influences on their concentrations in Tehran during 2012–2017
We investigated temporal variations of ambient air pollutants and the influences of meteorological parameters on their concentrations using a robust method; convergent cross mapping; in Tehran (2012–2017). Tehran citizens were consistently exposed to annual PM 2.5 , PM 10 and NO 2 approximately 3.0–...
