EVALUATION OF THE CORRELATION BETWEEN AMBIENT AIR POLLUTION LEVELS, TRAFFIC DENSITY, AND MICROCLIMATE PARAMETERS IN THE SOUTHERN KEY ECONOMIC ZONE

Tóm tắt

This study examined the intricate relationship between air quality, traffic density, and microclimatic elements within the Southern Key Economic Zone (SKEZ), where air pollution poses a significant environmental challenge. Using data from the Southern Center for Environmental Monitoring, we applied variance analysis and multivariate normal distribution methods to quantify these relationships. Our findings suggest that environmental quality parameters are affected by a plethora of factors, including vehicle type and microclimate. Noteworthy observations are as follows: (1) Total Suspended Particles: TSP concentrations are primarily influenced by temperature (1.99% contribution to variance), wind speed (2.66%), and the operational frequency of trucks and coaches (4.17%) and heavier trucks and buses (9.13%); (2) Nitrogen Dioxide and Sulfur Dioxide: NO2 and SO2 levels exhibit a strong correlation with wind speed, with respective contributions to variance of 4.47% and 6.12%; (3) Noise Pollution: Noise levels are directly affected by the operational frequency of motorcycles, trucks, coaches, and buses. Notably, trucks and buses had the most significant impact on the noise variance, accounting for 10.88%. These results highlight the multifaceted nature of environmental degradation in the Southern Key Economic Zone. Further research is necessary to develop targeted mitigation strategies that address the interplay among traffic patterns, vehicle emissions, and local meteorological conditions
