Purpose: Anthropogenic pollution has drawn attentionon Earth’s safety. Montreal Protocol 1989,approved a list of Ozone Thinners,but in 2015 at the far pole of the Antarctic,UV radiation measurements showed an increase in their concentration.This increase in UV radiation which was more concentratedat the South Pole,according to the EPA,can be attributed to the deep “hole” of ozone. The study identifies the lack of Ozone in the urban area and its trend.
Methodology: For this study, we analyzed data of Automatic Air Quality Monitoring in Tirana, Albania, for the period 2016-2019.
Result:Ozone Concentration:duringthe winter time, decrease according to a polynomial curve R2 = 0.979.In an Urban Area,during the summer months the concentration increases, whereas at night,for the same period, the concentration decreases. Reduced concentration at night, results according to a polynomial curveR2 = 0.955.Exponential increase in Nitrogen Oxide concentration NO: R2 = 0.862, is associated with an exponential decrease in O3 Ozone concentration: R2 = 0.948. Linear Temperature Increase: R2 = 0.669 as consequence of global warming, is associated with linear decreases of ozone concentration R2 = 0.634 in urban area.
Conclusions: Ozone level is related to solar exposure. This conclusion is also supported by data from other stations around the world.The reduction in Ozone concentration is affected by urban pollution. Increasing temperatures has an effect on Ozone reduction.High values during the day are a consequence of photolysis.
