“…Accumulation and deposition of gaseous pollutants and particulate matter depends upon the vegetation type (Bunzl et al, 1989;Fowler et al, 1989). Vegetation makes contribution in reducing dust concentration in environment by acting as a sink for air pollutants.…”

“…This altitude corresponds also to a more dense forest. The greater deposition of radionuclides in coniferous forests was already observed (9,10). This increase is due to the interception of radionuclides by the canopy and to the contribution of the Utter fall to the activity deposited on the forest floor.…”

Abstract. The study of an Alpine Wetland presented in this study can bring interesting answers to the problems of the environment management. The determination of the radionuclides in soils and sediments has allowed not only to establish the history of depositions and consequently the origin of the radionuclides, but also to evaluate the various transfers, which took place. The studied elements are plutonium 238, 239-240, americium 241, caesium 134, 137 and strontium 90. The detailed vertical study of sediment core shows the accumulation mode and gives information on the sedimentation rate of the small lake. The study of isotonic ratios allows understanding the origin and the environmental behaviour of the elements. Soil core inventory shows the activity on this region. The evolution of the activity versus the altitude is made.

“…It is important to determine canopy effects on the initial deposition of FD1NPP-derived radionuclides for elucidation of the subsequent radionuclide dynamics in forest ecosystems. However, since it takes some times to build monitoring and analysis systems for radionuclides, there were only two reports about radionuclide depositions in forested areas during the main emission period just after the Chernobyl (Bunzl et al, 1989) and FD1NPP (Kato et al, 2012) accidents. In these previous reports, it was emphasized that atmospheric deposition of radionuclides was intercepted and retained temporally by forest canopies, and then transferred to the forest floor gradually.…”

Abstract:The Fukushima Daiichi Nuclear Power Plant accident in 2011 resulted in releases of enormous amounts of radionuclides into the atmosphere. The radionuclides were deposited over a large forested area in the Tohoku and Kanto regions. There were few reports about the initial depositions of radionuclides on forest ecosystems during the main emission period. We investigated the initial radiocesium deposition at various forest sites. The deposition of radiocesium by bulk precipitation during the initial few months (approximately until the end of May just after the accident) ranged from 4.4-42.1 kBq m -2 while that by throughfall ranged from 2.1-36.6 kBq m -2. The ratio of radiocesium deposition by throughfall to that by bulk precipitation (D TF /D BP ) ranged from 0.13-0.66 during the first sampling period (approximately until the end of March just after the accident). In the following sampling periods, the radiocesium input by bulk precipitation decreased rapidly and became undetectable. The D TF /D BP ratios in these periods increased and then generally exceeded 1.0, meaning that the forest canopies gradually released the entrapped radiocesium. Atmospheric radiocesium inputs to forest ecosystems were strongly influenced by the forest canopy interception and temporal retention.
