Monitoring of the Atmospheric Deposition Loads of Selected Elements in Moss Occurring in the Forest in Relation to Traffic Intensity

Popis výsledku v původním jazyce

The goal of the study was to test post hoc if different intensity of traffic along roads close to sampling sites of moss, representing bio-indicator of territorial background air pollution loads in the Czech Republic, could affect element concentrations in this substance. The concentration of 37 elements was determined in samples of forest moss (mainly Pleurozium schreberi) collected at 284 sites accross the Czech Republic in the frame of the international moss monitoring campaign (programme UN ECE ICP-Vegetation) in 2005. The moss sampling sites were situated further than 100 and 300 m from local and main roads. Additionally data about the distance to the nearest road (no more than 2000 m away) and the data about average intensities of traffic of cars, trucks and motorbikes at the given road segments in 2005 were included in the analyses. Relationships between concentration of studied elements in moss samples and the distance of the sampling sites from the nearest road in the zone 100(300)-2000 m and 100(300)-500 m away from these roads were analysed. Relationships between element concentrations in moss and intensities of traffic of the given vehicle categories along these roads were studied as well. No significant increase in the element concentrations in moss samples collected in the tested zones towards the road proximity was found. However, significant increase of Cr, Cu, Fe, Mo, Sb, and Zn concentrations in moss in the zone 100(300)-2000 m was detected for the increasing intensities mainly of cars. In the zone 100(300)-500m, the element concentrations in moss were not significantly correlated with the distance of the sampling site from the road edge. In this zone the increase of traffic of all types of vehicles significantly increased total content of nitrogen in moss and increasing intensity of the motorbike traffic significantly increased concentration of Cu, Mn, S and Hg in moss.
