Abstract:
In this study, the average values of vertical velocity of particles emitted from an aluminum smelter in the surface layer of the atmosphere were estimated using a semi-empirical method. The method is based on regression analysis of the horizontal profile of pollutants measured along the selected direction using moss bioindicators. The selection of epiphytic mosses Sanionia uncinata was carried out in 2013 in the zone of influence of a metallurgical industry enterprise in the city of Kandalaksha, Murmansk region. The concentrations of As, Si, Ni, Zn, Ti, Cd, Na, Pb, Co, K, Ba, Ca, Mg, Mn, Sr, Fe, Al, V, Cr, Cu were determined using atomic emission spectrometry. The conducted assessments showed that the average particle velocity toward the Earth\'s surface, when considering large spatial and temporal scales, is tens of times higher than gravitational settling velocities.
摘要:
在这项研究中,使用半经验方法估算了铝冶炼厂在大气表层中排放的颗粒的垂直速度的平均值。该方法基于对使用苔藓生物指标沿选定方向测量的污染物水平剖面的回归分析。2013年,在Kandalaksha市的一家冶金工业企业的影响区进行了附生苔藓Sanioniauncinata的选择,摩尔曼斯克地区。As的浓度,Si,Ni,Zn,Ti,Cd,Na,Pb,Co,K,Ba,Ca,Mg,Mn,Sr,Fe,Al,V,Cr,使用原子发射光谱法测定Cu。进行的评估表明,粒子向地球表面的平均速度,当考虑到大的时空尺度时,比重力沉降速度高几十倍。
