Since 1998 USC has actively sponsored research related to the long term ecological and health consequences of the low level radiation that was dispersed over vast expanses of Europe. Investigators at USC have obtained funding from a variety of extramural sources including NSF, National Geographic, CRDF, and other private foundations and have published several seminal papers concerning the impacts of low level radioactive contaminants on ecological systems. This research is important for the understanding of long term consequences of radiation for ecosystem and human health and will be instrumental in predicting the environmental half-lives of these contaminants. This research is of significance for hazard assessment related to industrial, military or terrorist nuclear incidents.

 

Summary of principal findings to date that are published, in press or submitted (see attached list for citations):

 

1)      Surveys of bird populations indicate that mutation loads in natural populations are much higher than in uncontaminated areas.

2)      Literature reviews indicate that mutation rates in many different species of plants and animals (including humans) are higher than in control regions.

3)      Chernobyl populations exhibit a wide variety of morphological deformities that are not found in any normal population.

4)      Surveys of birds, insects, and spiders indicate that many species are either absent or in very low numbers in the Chernobyl region. Brightly colored and migratory species of birds appear to be particularly sensitive to radioactive contaminants.

5)      Studies of birds indicate that some species may only persist in the contaminated regions via immigration from uncontaminated areas. Without this immigration, perceived impacts would be even higher than current projections. Media reports of a “healthy” Chernobyl environment with rare species of birds and mammals are likely the result of immigrants and not locally sustained populations.

6)      Population and community studies suggest that antioxidants (e.g. vitamins A and E, and carotenoids) may provide protection against the mutagenic effects of radioactive contaminants.

7)      In a study of 1251 children living in the contaminated regions of Chernobyl, we find dramatic impacts of contamination on several hematological measures including platelets, red and white blood cell counts, and hemoglobin.  This is the first study of this sort to be reported.

 


Priorities for future studies:

 

1)      Chernobyl Children Study

 

USC is working in collaboration with the Scientific Center for Radiation Medicine, Academy of Medical Sciences of Ukraine, to analyze a 21 year dataset concerning health irregularities in children living in the Chernobyl affected territories. This long term dataset is unique and will provide detailed insights to the health consequences of radioactive contaminants. Our goal is to acquire the remaining data currently housed in Kiev and to develop a rigorous epidemiological program to fully exploit this untapped resource. Funding is needed for statistical analysis, travel to field sites, and detailed follow-up studies of affected children and their children. Many of the children in the initial cohort are now of child-bearing age and opportunities exist to acquire important and unique information concerning second generation effects of radioactive contaminants. Such information is critical for assessment of the long term health consequences following industrial, military or terrorist nuclear incidents.

 

2)      Chernobyl Ecosystem Study

 

USC now has a well established, internationally recognized track record of basic ecological and environmental studies of Chernobyl, with seven years of baseline data for several species. Funding is needed to continue our monitoring of primary study populations and expand our coverage to include additional affected populations in Ukraine, Belarus and Russia. Our goals are to rigorously assess population and community dynamics for birds, insects and plants with the ultimate aim of predicting ecosystem recovery times following nuclear incidents.  In addition, we are developing methods for rapid assessment of environmental impacts on DNA, populations and communities that will be invaluable for monitoring following other incidents. Preliminary data indicate that the Chernobyl ecosystem is presently improving and continued monitoring is essential for the development management plans related to nuclear incidents in the future.

Publications from USC Chernobyl Research:

 

 

1)      Determinants of Interspecific Variation in Population Declines of Birds after Exposure to Radiation at Chernobyl. This paper is in press at the Journal of Applied Ecology. It reports on a community analysis of bird species that appear to experience disproportionately higher population depression in response to radioactive contaminants in the Chernobyl zone. The main findings are that brightly colored  and migratory bird species are most likely to be absent or in low numbers in the more contaminated regions of the Chernobyl Zone. This is perhaps the first rigorous analysis of community level consequences of radioactive contaminants.

2)      Elevated Frequency of Abnormalities in Barn Swallows from Chernobyl:  This paper reports on the numbers and diversity of morphological abnormalities found in Chernobyl populations of barn swallow when compared to control populations in Ukraine, Italy, Spain and Denmark. This is possibly the first comprehensive survey of abnormalities in natural populations and suggests that the elevated mutation rates seen in Chernobyl populations are generating significant numbers of morphological defects.

3)      Children from Chernobyl Show Depressed Numbers of Red Blood Cells, Leukocytes and Platelets: This paper explores a unique dataset of children born and living in the Narodichesky region of Ukraine, a region that is moderately contaminated. This is the first comprehensive analysis of this unique group of children and this paper represents the first of a series that investigate many non-cancer morbidities observed in this population.

5)      Objections to the Chernobyl Forum Report: The official UN Chernobyl Forum report significantly underestimated the likely deaths from cancers in human populations of Europe. The UN predicts 4000 deaths, but reanalysis of the same data indicates that death rates will certainly exceed 9000, with 30,000 – 60,000 very likely. Mousseau et al. (2005) were the first to voice their objections to the Chernobyl Forum Report.

      And, for related information, see The Other Report on Chernobyl (TORCH).

 

6)      Review of Genetic Damage to Many Species: Mousseau and Moller’s reviews of other research have found more than 20 species that show genetic damage as a consequence of Chernobyl contaminants. This is the first systematic review of the genetic consequences of low dose radiation in a natural environment and suggests that such damage may be extensive.

7)      Survival and Reproduction are Dramatically Reduced in Chernobyl Swallows:  Because barn swallows return to the same nest year after year it is possible to track individual survival.  And, since these birds make their nests inside barns, it is possible to examine individual reproductive rates and offspring survival.  We have found that survival rates close the reactor in the most contaminated sites are close to zero.  In areas of moderate contamination, annual survival is less than 15- 25% (versus about 40% in control populations from Ukraine, Spain, Italy and Denmark).  Chernobyl populations also show dramatically reduced reproductive rates and lower offspring survival. This is perhaps the only published study that attempts to address questions of reproduction and survival for any species in the Chernobyl Zone. There has been virtually no other research of this type, probably due to the lack of funding for this sort of research.

8)      Stable Isotope Analyses Indicate Chernobyl Populations are Sinks:  Using high tech geochemical approaches, we have determined that the Chernobyl barn swallow populations are only sustained via immigration from adjacent, uncontaminated populations.  Using stable isotope analyses on current and past specimens (from museums) we have inferred that current Chernobyl populations are composed of a more diverse group of individuals (i.e. immigrants) than is observed in control populations or in populations collected from the Chernobyl region prior to the disaster.

9)       Antioxidants, Radiation and Mutations:  Investigations of individual birds have revealed that in areas of high contamination, antioxidants (i.e. vitamins A and E, and carotenoids) are depressed.  Depressed antioxidants appear related to increased mutation rates (as has been found in many other species, including humans).  In Chernobyl barn swallows, depressed antioxidants are associated with dramatically increased rates of defects in sperm, a phenomenon linked to depressed fertility in many species.

10)  Mutation in Morphological Characters: It has also been observed that the sort of characters that seem most affected by increased mutation rates are those that may be very important to reproductive behavior in barn swallows.

11)  Albinism in Chernobyl Barn Swallows:  Mousseau and colleagues have investigated the consequences of elevated mutations in barn swallow populations living in the contaminated regions of Ukraine.  The principle findings are that there are many visible mutations observed, including dramatically increased rates of partial albinos.  The expression of this mutation, which is analogous to vitiligo in humans, is likely related to depressed antioxidants observed in these birds.
