This study investigated the variability of radioactive and stable aerosols (7Be, 210Pb, 137Cs, 40K, PM10, and PM2.5) in relation to mixing layer height (MLH) based on outdoor radon and meteorological factors in Bratislava, Slovakia from 2017 to 2021. Aerosol concentrations exhibit distinct seasonal patterns, with higher 7Be concentrations in summer and lower in winter, while 137Cs, 40K, 210Pb, PM10 and PM2.5 showed almost the opposite trends. Different statistical techniques, including Pearson's correlation analysis, multiple regression analysis (MRA), and canonical correlation analysis (CCA), were employed to elucidate the intricate relationships between aerosol concentrations, MLH, and meteorological parameters. The MRA identified a significant correlation between aerosol variability and specific predictors, while the CCA highlighted the differential influence of MLH and meteorological parameters on aerosol concentrations. The analysis revealed that temperature, MLH, and relative humidity are the primary factors influencing aerosol concentrations, underscoring their pivotal role in environmental dynamics.

气象和混合高度对斯洛伐克布拉迪斯拉发放射性和稳定气溶胶的影响


本研究调查了 2017 年至 2021 年斯洛伐克布拉迪斯拉发基于室外氡和气象因素的放射性和稳定气溶胶 （7Be、210Pb、137Cs、40K、PM10 和 PM2.5） 与混合层高度 （MLH） 的关系变化。气溶胶浓度表现出明显的季节性模式，夏季 7Be 浓度较高，冬季较低，而 137Cs、40K、210Pb、PM10 和 PM2.5 则表现出几乎相反的趋势。采用了不同的统计技术，包括 Pearson 相关分析、多元回归分析 （MRA） 和典型相关分析 （CCA），来阐明气溶胶浓度、MLH 和气象参数之间的复杂关系。MRA 确定了气溶胶变异性与特定预测因子之间的显着相关性，而 CCA 强调了 MLH 和气象参数对气溶胶浓度的不同影响。分析表明，温度、MLH 和相对湿度是影响气溶胶浓度的主要因素，强调了它们在环境动力学中的关键作用。
