Analysis of a twenty-year (1998–2018) data series on ⁷Be concentrations in weekly collected aerosol samples in northern Poland showed a clear pattern of seasonal changes in ⁷Be with a maximum in the summer period associated with the most intensive thermal convection and vertical mixing. Activity concentrations of ⁷Be ranged from 480 μBq m⁻³ to 9370 μBq m⁻³. A strong relationship has been shown between ⁷Be concentrations observed in years and the activity of the Sun related to the sunspot number. Activity concentrations of ²¹⁰Pb in aerosol ranged from 17 μBq m⁻³ to 1490 μBq m-3 with maximum occurring in the winter. The difference in the seasonal pattern in ⁷Be and ²¹⁰Pb concentrations were directly related to the different sources of both isotopes, as an additional source of ²¹⁰Pb was the products of combustion during the heating season. Similar pattern with maximum concentrations in winter was observed for PM10, as the main source is the same as in the case ²¹⁰Pb. A content of PM10 was in the range from 6.5 to 81.7 μg m⁻³. A statistically significant correlation between both isotopes occurs. At the same time, ⁷Be, ²¹⁰Pb and PM10 are visibly related to the dust concentrations ranged from 7.3 μg m⁻³ in winter to 134.8 μg m⁻³ in spring. Statistical analysis carried out with simple regression model, stepwise multiple regression, and Random Forest models showed that the sunspots number, air temperature and sunshine duration have the most substantial impact on transport, and hence the concentration of ⁷Be in the surface layer of the atmosphere. The increase in relative humidity and precipitation and higher wind speed have a statistically significant effect on the reduction of ⁷Be concentrations in surface air.

对波兰北部每周收集的气溶胶样品中⁷ Be浓度的二十年（1998-2018）数据系列的分析显示，⁷ Be的季节变化具有明显的季节性变化，夏季期间最大，这与热对流和强度最大有关。垂直混合。⁷ Be的活性浓度范围从480μBqm ^-3到9370μBqm ^-3。在几年中观察到的⁷ Be浓度与太阳活动与黑子数相关之间已显示出很强的关系。气溶胶中²¹⁰ Pb的活动浓度范围为17μBqm ^-3至1490μBqm-3，冬季最高。⁷ Be和²¹⁰ Pb浓度的季节性变化差异与两种同位素的不同来源直接相关，因为²¹⁰ Pb的另一个来源是加热季节的燃烧产物。由于主要来源与²¹⁰ Pb的情况相同，因此在PM10中观察到了冬季最大浓度的相似模式。PM10的含量在6.5至81.7μgm ^-3的范围内。两种同位素之间存在统计学上的显着相关性。同时，可见到⁷ Be，²¹⁰ Pb和PM10与7.3μgm ^-3的粉尘浓度有关冬季为134.8μgm ^-3。用简单回归模型，逐步多元回归和随机森林模型进行的统计分析表明，黑子数，气温和日照时间对运输有最大的影响，因此大气表层中⁷ Be的浓度。相对湿度和降水的增加以及较高的风速对减少表面空气中⁷ Be的浓度具有统计学上的显着影响。
