摘要

本文介绍了对扎波罗热州大气气溶胶、土壤、底部沉积物、第聂伯罗河悬浮物和扎波罗热州平炉湿气过滤器中工艺铅分布的地球化学特征的长期观测结果。实际资料是在2015-2019年综合现场监测的基础上获得的。研究区水文气象条件(季节、降水、风速、风向和持续时间)数据的同步参与为研究成果的处理和推广提供了一个完整的方法。定义了大气中沉积物质分布的一些特点,以及其人为成分和自然成分的相互关系。揭示了铅浓度变化与风成矿物成分分布、季节性和许多其他因素之间的相关性。监测点沉积物捕集器积聚的固体气溶胶颗粒中铅浓度最高。结果表明,第聂伯罗河悬浮液中所调查元素的平均浓度明显超过背景值,土壤中所调查元素的平均浓度超过允许标准的3.5倍以上。与此同时,大气气溶胶中铅的固定形态与其他环境物体相比,失去了主导地位,让位于易溶解形态,因此成为环境危害的证据。对城市空气中铅元素分布的季节模式监测显示,在一年中寒冷时期铅的浓度过高,这是由于气象条件和自然和人为因素的重新分配,这些因素在一年中不同季节对大气中铅的到达和转化过程起着驱动作用。

Lead Distribution in Ground-Level Atmospheric Aerosol of Zaporizhia City
The results of long-term observations on the geochemical peculiarities of technogenic lead distribution in atmospheric aerosol of Zaporizhia, as well as in soils, bottom sediments, suspended matter from Dnipro river and substance from wet gas filters of open-hearth furnaces PJSC Zaporizhstal are presented. The actual material was obtained on the basis of comprehensive field monitoring during 2015-2019. Simultaneous involvement of data on hydrometeorological conditions (seasonality, precipitation, wind speeds, directions and duration) in the study area provided a integral approach to the processing and generalization of research results. A number of peculiarities of sedimentary substance distribution in air, interrelations of its anthropogenic and natural components are defined. Correlations were revealed between lead concentrations changes and aeolian mineral component distribution, seasonality, and a number of other factors. The highest concentration of lead was found in solid aerosol particles accumulated by the sedimentary trap at the monitoring site. It was revealed that the average concentration of investigated element in river suspension of Dnipro exceeds significantly background values, and for soils exceeds more than 3.5 times the permissible norms. At the same time, the fixed form of lead in atmospheric aerosol, in contrast to other environmental objects, loses its domination, giving the way to easily soluble forms, so the evidence of environmental hazard. Monitoring of seasonal patterns of the element distribution in the city air showed excess concentrations in the cold period of the year, which, according to the authors, is due to both meteorological conditions and redistribution of natural and anthropogenic factors that serve the driving force in processes of arriving and conversion of lead in atmosphere during different seasons of the year.
