“…For the Palatinate Forest we could show as demonstrated in some earlier studies (Fielitz 1992;Haffelder 1995;Hecht and Honikel 1997;Zibold et al 2001) that Cs-concentration in the wild boar follows some kind of seasonality due to the varying food composition in their diet in the course of the year (Groot Bruinderink et al 1994;Tucak 1996). In southeastern Germany (Bavaria) studies of wild boar in contaminated areas have shown that Cs-concentration in muscle tissue often peaks between January and April and starts to decrease mostly in May or July, reaching its minimum in October-December Schwind et al 2002).…”

“…Radiocaesium is more readily available to the organisms in the forest ecosystems than in the agricultural areas owing to the difference in soil characteristics. As a consequence many plant and fungal species occurring in forests as well as wild ungulates are still significantly contaminated (Zibold et al 2001;BfS 2002;Schwind et al 2002). Whereas radiocaesium concentration in red deer (Cervus elaphus) and roe deer (Capreolus capreolus) venison has decreased 18 years after the Chernobyl accident, radiocaesium contamination of wild boar (Sus scrofa) venison remains high in areas of Bavaria (Hecht 2001;Schwind et al 2002;Steiner 2003) or it has erupted in formerly less conspicuous regions (Pohlschmidt 2000;Schu¨rmann 2002;Metschies et al 2003;Putyrskaya et al 2003).…”

To substantiate the pathways of radiocaesium contamination in wild boars in parts of RhinelandPalatinate, we analysed radiocaesium-activityconcentration of 2,433 wild boars shot in an area covering 45,400 ha in the western part of the Palatinate Forest between January 2001 and February 2003. Also, for a fraction of 689 animals shot between May 2002 and February 2003, we collected their stomachs for the examination of content and Cs-activity concentration. Wild boar meat contamination followed a seasonal curve with maximum proportions exceeding accepted levels in the summer (21-26%) and minimum levels in winter (1-9.3%) indicating a higher consumption of a contaminating source during the vegetation period. The autumn decline is obviously attributed to the extensive consumption of low-contaminated beech nuts. An exact analysis of food composition in 18 stomachs with maximum Cs-activity concentrations [345-1,749 Bq/kg (fresh matter: fm)] and 18 with low Cs-activity concentrations ( £ 20-199 Bq/kg) was carried out in the summer of 2002. Deer truffles (Elaphomyces granulatus) were found in significantly higher proportions in stomachs with maximum contamination levels than in stomachs with lowcontamination levels. This fungus was found in the Palatinate Forest, by a trained dog, in average densities of 1 truffel/20 m 2 primarily in spruce stands, showing an average Cs-concentration of 6,030 Bq/kg (fm). On the basis of our findings we stress the hypothesis that deer truffles function as a main Cssource for the wild boar in Rhineland-Palatinate.

“…Thus, fungal activity is likely to contribute substantially to the long-term retention of radiocesium in the organic layers of forest soil by recycling and retaining radiocesium between fungal mycelia and soil (Muramatsu and Yoshida 1997 ;Steiner et al 2002 ;Muramatsu 1994 , 1996 ). In fact, some examples have been Cs radioactivity in mushrooms persisted for a long period in forests and was transferred to animals, whereas that in plants had short ecological half-lives (e.g., 3-3.5 years) (Fielitz et al 2009 ;Kiefer et al 1996 ;Zibold et al 2001 ).…”

High concentrations of radionuclide contamination of wild mushrooms occurred near the Fukushima Daiichi nuclear power plant and along the path of radioactive plumes. This is a serious problem for the forest ecosystem and commercial wild mushroom production. Radioactivity in wild mushrooms collected from low-level contamination forest areas throughout Japan was measured approximately 6 months after the accident. In general, the radioactivity in mushrooms did not exceed those in the neighboring forest litter. However, further accumulation of 137 Cs is expected in mushrooms; therefore, continuous monitoring is necessary even in low-contamination areas. We also found that residual 137 Cs radioactivity due to nuclear weapons tests, mainly in 1950s, besides fallout from the Fukushima nuclear accident still remained in soil and was accumulated by mushrooms.

“…Soon after the Chernobyl accident roe deer feeding preference with high amounts of mushrooms was suggested as explanation for their comparatively high 137 Cs contamination (Tataruch et al, 1989). On the basis of a comprehensive monitoring data set, Zibold et al (2001) proved that the contamination of roe deer samples is highly dependent on the mushroom availability in autumn, which was dependent upon precipitation. This leads to increased T ag -values of roe deer in the second half of the year.…”
