Project Tocoen: The fate of selected organic pollutants in the environment part xxiv. The content of PCBs and PCDDs/Fs in high‐mountain soils

Immediate Impact of the Flood (Bohemia, August 2002) on Selected Soil Characteristics

“…The cycle starting with the long range transport of pollutants as already described (Holoubek et al, 1994, Holoubek et al, 1998Blais et al, 1998), followed by their wash out by heavy rainfalls on the slopes above ca. 800 m a.s.l.…”

Project TOCOEN (toxic organic compounds in the environment) part XXXI. The occurrence of POPs in high mountain ecosystems of the Czech republic

“…During this campaign, the ambient air, soils and needles samples were collected and analysed. These results will be compared with our older data [2] and with the Downloaded by [The UC Irvine Libraries] at 16:04 04 November 2014 values from relatively clean area in South Bohemia (Chlum u Tfebonë) and observatory Kosetice.…”

“…We can supposed as concerning to results from the first campaign [2] that in this area-in south part of "Black triangle" -the combined inputs of organochlorines and other POPs to forest soils. The first is probably longrange transport from the sources inside and outside of this region and the second can be from the forest comporting processes [9,10].…”

“…The highest concentration is in Beskydy mountains (3 220.13 ng-kg" 1 , 49.24 ng-kg~' TEQ) followed by Luzické hory mountains (2 727.13 ng-kg" 1 , 44.01 ng-kg" 1 TEQ), but the highest toxicity has Krkonose mountains (53.51 ng-kg" 1 ). When we calculate with additional contribution of planar PCBs to the total TEQ, which ranged between 9.3 and 49.3% [2], we will get the value which should be monitored at least, from the point of view of the future development of the whole high mountain ecosystem.…”

“…Understanding the transport mechanisms of these contaminants in the environment is essential [1,2]. The predominant part of the long-range transport takes place in the atmosphere.…”
