Title: ACCUMULATION OF RADIOCESIUM BY MUSHROOMS IN THE ENVIRONMENT: A LITERATURE REVIEW AND IMAGE GALLERY

Keywords: 54 ENVIRONMENTAL SCIENCES; CONTAMINATION; IMAGES; MUSHROOMS; SAMPLING; SOURCE TERMS; CESIUM 137; BIOLOGICAL ACCUMULATION; CESIUM 134
Abstract: During the last 50 years, a large amount of information on radionuclide accumulators or ‘sentinel-type’ organisms in the environment has been published. Much of this work focused on the risks of food-chain transfer of radionuclides to higher organisms such as reindeer and man. However, until the 1980’s and 1990’s, there has been little published data on the radiocesium ({sup 134}Cs and {sup 137}Cs) accumulation by mushrooms. This presentation will consist of a review of the published data for {sup 134,137}Cs accumulation by mushrooms in nature. The review will consider the time of sampling, sample location characteristics, the radiocesium source term and other aspects that promote {sup 134,137}Cs uptake by mushrooms. This review will focus on published data for mushrooms that demonstrate a large propensity for use in the environmental biomonitoring of radiocesium contamination. It will also provide photographs and descriptions of habitats for many of these mushrooms to facilitate their collection for biomonitoring.

Title: Transgenic plants are sensitive bioindicators of nuclear pollution caused by the Chernobyl accident.

Abstract: To evaluate the genetic consequences of radioactive contamination originating from the nuclear reactor accident of Chernobyl on indigenous populations of plants and animals, it is essential to determine the rates of accumulating genetic changes in chronically irradiated populations. An increase in germline mutation rates in humans living close to the Chernobyl Nuclear Power Plant site, and a two- to tenfold increase in germline mutations in barn swallows breeding in Chernobyl have been reported. Little is known, however, about the effects of chronic irradiation on plant genomes. Ionizing radiation causes double-strand breaks in DNA, which are repaired via illegitimate or homologous recombination. We make use of Arabidopsis thaliana plants carrying a beta-glucuronidase marker gene as a recombination substrate to monitor genetic alterations in plant populations, which are caused by nuclear pollution of the environment around Chernobyl. A significant (p<0.05) increase in somatic intrachromosomal recombination frequencies was observed at nuclear pollution levels from 0.1-900 Ci/km2, consistent with an increase in chromosomal aberrations. This bioindicator may serve as a convenient and ethically acceptable alternative to animal systems.
