摘要：The purpose of the article is to highlight the efficiency of the retention capacity of green infrastructure in reducing PM10 concentrations in the Timisoara agglomeration. We propose a methodology to highlight the benefits of the green spaces applied at the level of Timişoara agglomeration, in which is used the internal variability of the green spaces (plant species, tree height, tree density) correlated with the spatial analysis of the dispersion of the suspended particle concentrations PM10, to highlight by a theoretical model the absorption/filtration of particles. Following the calculations, it was estimated that the green infrastructure has a minimum retention capacity of approximately 0.01 % and a maximum of 10.39 % of the concentration of PM10 suspended particles, to which the green infrastructure is exposed. We mention that the article was made using non-confidential data presented in the Air Quality Plan for PM10 proposed in public debate on the website of Timisoara City Hall. Also, the company S.C. MULTIDIMENSION S.R.L. made the Study on air quality in the Timişoara agglomeration, which was the basis for the elaboration of the Air Quality Plan for the PM10 indicator in the Timişoara agglomeration.
