Seasonal and regional variations in the transfer of cesium radionuclides from soil to roe deer and plants in a prealpine forest

Influence of fertilizing on the 137Cs soil–plant transfer in a spruce forest of Southern Germany

“…The differences in fractional 137 Cs inventories of soil horizons in fertilized and non-fertilized sites can be attributed to the stronger binding and the smaller bioavailability of Cs in O h horizons of the fertilized sites, and agrees with the lower fractional inventories found in the L, and O f horizons from this part, due to the lower activity concentrations of the plant cover (Lindner et al, 1994). The observed increase in pH after fertilization supports the observed smaller bioavailability on fertilized sites.…”

“…These equations are used to predict the values of TF, the transfer of 137 Cs from the root zone to the plant. The same equations were used by Konopleva et al (2009) to explain that in spruce forest the bioavailability of radiocaesium was on average seven times higher than in mixed forest on sites in the neighbourhood to those of this study (Lindner et al, 1994). Soil pH was measured in 0.01 M CaCl 2 using a solid-liquid ratio of 1:2.5 for mineral layers and a solid-liquid ratio of 1:5 for organic layers after 2 h of equilibration.…”

“…A one-time treatment of a spruce forest site (Baden-Wü rttemberg, Germany) in 1984 with fertiliser consisting mainly of CaCO 3 has been found to reduce substantially the 137 Cs uptake. At this site the highest fraction of the total caesium inventory was found in the O h horizon, rich in organic matter (Lindner et al, 1994). After the treatment the effect of liming has been measured in the years between 1991 and 1996 Zibold et al, 1997Zibold et al, , 2003.…”

Ecological half-lives of 90Sr and 137Cs in terrestrial and aquatic ecosystems

“…Furthermore, the ecological half-lives appear to increase with the length of observation period, which might indicate that different processes (e.g. redissolution) Drissner et al (1996), Kiefer et al (1996), Klemt et al (1996Klemt et al ( , 1999, Lindner et al (1994), Zibold et al (1989Zibold et al ( , 2001 Roe deer a Januarye December, muscle .…”
