Abstract:
Air quality monitoring is essential for understanding environmental conditions and protecting public health. This study aims to comprehensively analyze air quality in Bucharest and Cluj by focusing on particulate matter (PM2.5, PM10) concentrations. The study aims to assess the levels, variability and distribution of PM2.5 and PM10 concentrations, to identify spatial and temporal patterns, and to do short-term predictions for air quality. Particulate matter data was collected using low-cost sensors located across Bucharest and Cluj. Statistical methods, including descriptive analysis and the Autoregressive Integrated Moving Average (ARIMA) model were applied to the PM data series. The ARIMA model, a time series analysis technique, was used to make short-term predictions based on historical data. The statistical analysis revealed significant spatial and temporal variations in PM2.5 and PM10 concentrations in the two cities. Pollution hotspots were identified, highlighting areas with high pollution levels. The study demonstrates the effectiveness of statistical methods, particularly the ARIMA model, in analyzing and predicting air quality in Bucharest and Cluj. The study also emphasizes the importance of continuous monitoring and data-driven approaches for improving air quality and public health in urban areas. The study findings support the implementation of effective strategies and policies to mitigate air pollution and create healthier living environments in Bucharest and Cluj.
