Abstract Air pollution is a multifaceted issue affecting people’s health, environment, and biodiversity. Gaining comprehension of the interactions between natural anthropocentric pollutant concentrations local climate challenging. This study aims to address following two questions: (1) What influential mechanism climatic anthropogenic factors on ground-level ozone (O 3 ) in an urban environment during different seasons? (2) Can weekend effect be observed medium-sized city like Craiova, under which conditions? In order answer these questions, with meteorological parameters (temperature, pressure, relative humidity) (particulate matter, carbon dioxide, volatile organic compounds, formaldehyde, nitrogen nitric oxide monoxide) evaluated based one-year dataset given by low-cost sensor provided National Environment Agency. Using statistical analysis programs, Python SPSS, good understanding correlations variables concentration obtained. The SPSS underscores significant impact three nine other pollutants level. A positive correlation noticed summer when sunlight intense photochemical reactions are elevated. relationship temperature strong positive, as confirmed Spearman’s rho coefficient ( r = 0.880). negative found humidity -0.590). Moreover, shows that particulate matter exhibit ≈ -0.542), indicating higher reduce levels.
