Russia/Ukraine/ex-USSR

The former Soviet Union was rocked by one of the world's worst environmental disasters on April 26, 1986, when Unit 4 at the Chernobyl reactor site exploded, sending a radioactive plume across the world. The former Soviet Union is still also the site of some of the world's worst radioactive contamination from its nuclear weapons program.

Chernobyl no "Eden" after 28 years

A newly published study has uncovered alarming indications of biological loss and ecological collapse in the area around the Chernobyl nuclear reactor that exploded in Ukraine on April 26, 1986. 

Nuclear boosters have long claimed that the superficial appearance of teeming wildlife in the approximately 1,000 square mile Chernobyl exclusion zone indicates an Eden-like outcome. But the study observed a frightening halt to organic decay and the disappearance of important microbes that indicate the steady advance of a potential “silent spring.” 

“The illusion that the absence of humanity can only benefit wildlife is trumped when humanity has inflicted man-made poisons on a fragile ecosystem whose inhabitants are now biologically compromised by radiation exposures that will continue indefinitely,” observed Linda Gunter, international specialist at Beyond Nuclear, of the study’s findings.

 

Highly reduced mass loss rates and increased litter layer in radioactively contaminated areas, published in Oecologia, March 4, 2014, by Mousseau (Dr. Tim Mousseau pictured), Milinevsky, Kenney‑Hunt and Møller, found that the natural cycle of decay of organic materials around Chernobyl is largely dependent on microbial communities which have been significantly reduced in these radioactively contaminated zones. 

“We already know about plant and insect mutations and the shortened lifespans of birds in the zone, but this news is even more alarming,” said Paul Gunter, Director of Reactor Oversight at Beyond Nuclear. “The long-term consequences of the loss of this essential microbial community could be unprecedented ecologically, while the most immediate consequence is the build-up of undecayed leaf matter. This creates an increased risk of forest fires which could spread radioactivity to uncontaminated areas,” Gunter said.

Decay takes a holiday: the wickedness beneath the “Chernobyl wild paradise” myth and the rotten implications for ecosystems and radiation science

Zombie forest?

April 26, 2014 will mark 28 years since the Chernobyl nuclear reactor exploded causing an unprecedented nuclear catastrophe. In a creepy revelation, the forests around Chernobyl are having difficulty decomposing. A recently published study indicates that forest matter in the contaminated areas around Chernobyl is taking years or even decades longer to decay than it should. In the areas with low radiation, 70 to 90 percent of the leaves were gone after a year. Where radiation levels were higher, “leaves retained around 60 percent of their original weight...”(Smithsonian.com) This indicates a fundamental disruption to the natural cycle of death feeding life, and calls into question the forest’s longer-term viability. Creatures responsible for decay such as microbes, fungi and some types of insects, are essential components of any ecosystem because they recycle organic material back into the soil. Unfortunately, they do not function properly in the areas around Chernobyl, leaving a forest full of “petrified-looking pine trees that no longer seem capable of rotting.” GIZMODO

Radiation’s effect on decay processes should be expected, considering how it impacts microbes in food; or considering the results of a bizarre, cavalier and extremely ill-advised series of experiments performed using a “naked reactor” in the late 1950’s and early 1960’s. These experiments intentionally irradiated a number of varying materials and forest land 40 miles north of Atlanta, GA. Wood subjected to this radiation was produced in small-scale and called “Lockwood”, for Lockheed Aircraft Corporation who operated the Georgia Nuclear Laboratory. The building and land is still contaminated with radionuclides.

The lack of decomposer activity has researchers worried that nutrients which trees require for grow are not being recycled, causing trees in the area to grow more slowly.  Improper plant decay has potential implications for animal decay as well, although there do not appear to be any Chernobyl studies investigating this yet.

Stalked by Forest Fires

This lack of rotting is also causing the forest litter to pile up and become a fire hazard. Fire could not only destroy the forests further, but can spread the current radioactive contamination to other, potentially uncontaminated areas. “A devastating radioactive smoke cloud” could be carried large distances past Ukraine and right across Europe (again), putting people and farmland at further risk. Each year, Chernobyl firefighters manage up to 80 forest fires, sometimes experiencing metallic “taste” and a tingling of their skin that indicates exposure to higher radiation levels.

One fire in 1992 spread unchecked and destroyed a large area of contaminated forest. Scientists are still studying the effects of that fire and hope to use this data to pinpoint stands of vulnerable pines and other forest areas that should be cleared to lessen potential fire risk. Ukraine does not have the money to clear all contaminated forest vegetation. The lingering threat of forest fires and the inability to rot proves the Chernobyl nuclear disaster is anything but over even though the reactor leaks have long since stopped.

The research team that conducted the decay study and a number of other wildlife studies around Chernobyl, is collaborating with investigators in Japan to determine if improper decay is occurring in areas contaminated with Fukushima radiation.

Scientific fantasy versus ugly reality

As if plant matter’s inability to decompose isn’t unsettling enough, a study published in 2013 indicates that controlled experiments designed to examine the impact of radiation dose and dose rates on biological organisms may underestimate the impact by 8 to 10 times. This indicates that organisms in their natural environment are more sensitive to radiation. Perhaps this dichotomy between what happens in a controlled environment and what occurs in nature is in part due to a growing radiosensitivity among the forest’s inhabitants.

Studies examining Chernobyl animal populations living in chronic low-dose radiation (summarized by Goncharova in 1998) show an increase in radiosensitivity among those whose ancestors were exposed. This indicates that successive generations could be less able to cope with the same degree of exposure as their parents were and that, for certain animal species, there is no genetic adaptation to mutations from low-dose, chronic, man-made radiation exposure—the kind received from nuclear power whether or not there is an accident.

Importantly, a growing radiosensitivity among the individual of a population over generations would mean that research used to predict radiation damage, if based data from earlier generations, would not be reflective of damage to the current generation. Likewise, research used for long-term radiation exposure protection that relies on controlled experiments could be extremely unprotective. These two scenarios call into serious question our current radiation protection systems.

Møller)Actual in-the-field examinations of regions contaminated by radioactivity from Chernobyl also reveal evidence for increased mutation rates, abnormal sperm with reduced swimming ability, developmental abnormalities, cataracts, tumors, smaller brains in both birds and mammals, and decreased tree growth rates, a finding of fundamental importance for ecosystem functioning that likely relates to effects on the microbial community. Fewer spiders and insects including bees, butterflies and grasshoppers—live there. Animals and plants show other impacts of radiation after the Three Mile Island nuclear disaster in the US and the Fukushima nuclear disaster in Japan.

Timothy Mousseau, a biologist at the University of South Carolina, Columbia, who collaborated on many of these studies, contends that, fundamentally, this evidence indicates low-dose rate exposures cause significant measurable impacts for the biota inhabiting contaminated regions of Chernobyl. Further, this evidence supports a hypothesis that suggests effects down to very low levels.  Further implications for Fukushima should not be ignored.

Humans and animals alike: healthy looking on the outside, disintegrating on the inside

Referencing studies summarized in his book, Chernobyl: Consequences of the Catastrophe for People and the Environment, Alexey Yablokov states:

“Wildlife in the heavily contaminated Chernobyl zone sometimes appears to flourish, but the appearance is deceptive,” says Yablokov. “Levels of incorporated radionuclides remain dangerously high for mammals, birds, amphibians, and fish. Long-term observations of both wild and experimental animal populations in the heavily contaminated areas show significant increases in morbidity and mortality that bear a striking resemblance to changes in the health of humans – increased occurrence of tumours and immuno­deficiencies, decreased life expectancy, early aging, changes in blood and the circulatory system, malformations, and other factors that compromise health.

“All of the populations of plants, fishes, amphibians and mammals studied there are in poor condition,” he continues. “This zone is analogous to a ‘black hole’, in which there is accelerated genetic degeneration of large animals – some species may only persist there via immigration from uncontaminated areas. The Chernobyl zone is a micro-evolutionary ‘boiler’, where gene pools of living creatures are actively transforming, with unpredictable consequences. We ignore these findings at our peril.”

Dr. Yablokov’s statement deftly presents the dichotomy between what is observed by a dilettante’s eye – such as lots of members in a wild animal population -- versus what is actually happening to these members over time. What is happening to this wildlife has parallel implications for human health.

So where did this “paradise for wildlife” and “biodiversity sanctuary” myth come from? In 2006 the International Atomic Energy Agency, a nuclear power promoter and a member body of the United Nations, released a report entitled Environmental Consequences of the Chernobyl Accident and their Remediation: Twenty Years of Experience. This report references the creation of a nature preserve within the Chernobyl Exclusion Zone and remarks Without a permanent residence of humans for 20 years, the ecosystems around the Chernobyl site are now flourishing. The CEZ has become a wildlife sanctuary…, and it looks like the nature park it has become.” From another report: “Indeed, the Exclusion Zone has paradoxically become a unique sanctuary for biodiversity.”

The Chernobyl Forum coalition makes this statement in support of “unique biodiversity” in spite of their recognition that “Genetic effects of radiation, in both somatic and germ cells, have been observed in plants and animals of the Exclusion Zone during the first few years after the Chernobyl accident. Both in the Exclusion Zone, and beyond, different cytogenetic anomalies attributable to radiation continue to be reported from experimental studies performed on plants and animals.” They conclude, however, “[w]hether the observed cytogenetic anomalies in somatic cells have any detrimental biological significance is not known.” In order to know this, one has to actually look.

The study summaries compiled by Alexey Yablokov, et al. (studies which had been mostly unavailable in the west until 2009) and the published examinations of researchers Mousseau, et al., indicate rather strongly that there is significant biological detriment to wildlife in the contaminated areas surrounding Chernobyl. And unlike these studies, the Chernobyl Forum documents provide very few references (under ten total) for any claims they make regarding the flourishing of wildlife.

Forests Around Chernobyl Aren’t Decaying Properly

"Nearly 30 years have passed since the Chernobyl plant exploded and caused an unprecedented nuclear disaster. The effects of that catastrophe, however, are still felt today. Although no people live in the extensive exclusion zones around the epicenter, animals and plants still show signs of radiation poisoning.

Birds around Chernobyl have significantly smaller brains that those living in non-radiation poisoned areas; trees there grow slower; and fewer spiders and insects including bees, butterflies and grasshoppers—live there...

In the areas with no radiation, 70 to 90 percent of the leaves were gone after a year. But in places where more radiation was present, the leaves retained around 60 percent of their original weight..." supporting the idea of delayed decay.

The researchers worry that not only are these nutrients not being properly recycled, causing trees to grow more slowly, but the lack of decomposition is causing the forest litter to pile up and become a fire hazard. Fire can not only destroy the forests further, but can also spread the radioactive contamination now present to other, potentially uncontaminated areas. Smithsonian.com
