Atomic history, nuclear future

October 19, 2008

We’re going to see more nuclear power plants in the U.S., it’s a safe bet.  Both presidential candidates support developing alternatives to oil and coal.  Nuclear power is one of the alternatives.

John McCain kept repeating his comfort words, that ‘storage of wastes is not a problem.’ There is not a lot of evidence to support his claims.  With turmoil in financial markets, however, the nuclear power issue has gotten very little serious attention or scrutiny.  From the push to get compensation for radiation victims of atomic weapons and development in the U.S., I learned that the issue is not really whether wastes and other materials can be safely used and wastes stored. The issues are entirely issues of will.

Advantage to Obama, I think.  He’s not claiming that the storage problems are all solved.  A clear recognition of reality is good to have in a president.

Son Kenny sent a link to a history site, Damn Interesting, and it tells the story of the Techa River in the old Soviet Union — a place condemned for generations by the nuclear excesses of the past.

To make the story briefer, in their rush to produce nuclear weapons, the Soviets did nothing to protect Russia from radioactive waste products until it was much too late.  Efforts to reduce radioactive emissions, by storing them in huge underwater containers, resulted in massive explosions that released more radiation than Chernobyl (What?  You hadn’t heard of that, either?).

It’s a reminder that safety and security with peaceful uses of nuclear power depend on humans doing their part, and thinking through the problems before they arise.

Can we deal with radioactive wastes?  We probably have the technology.  Do we have the will? Ask yourself:  How many years has the U.S. studied Yuccan Mountain to make a case to convince Nevadans to handle the waste?  How many more decades will it take?

How is our history of dealing with nuclear contamination issues?  Not good.

Last spring SMU’s history department sponsored a colloquium on a power generation in the southwest, specifically with regard to coal and uranium mining on the Navajo Reservation.   We’ve been there before.

One of the photos used in one of the lectures, by Colleen O’Neill of Utah State, showed two Navajo miners outside a uranium mine during a previous uranium boom.  Neither one had a lick of protective equipment.  Underground uranium mining exposes miners to heave concentrations of radon gas, and if a miner is unprotected by breathing filters at least, there is a nearly 100% chance the miner will get fatal lung cancers.

Of the 150 Navajo uranium miners who worked at the uranium mine in Shiprock, New Mexico until 1970, 133 died of lung cancer or various forms of fibrosis by 1980 ([Ali, 2003] ).

Our Senate hearings on radiation compensation, in the 1970s, produced dozens of pages of testimony that Atomic Energy Commission officials understood the dangers, but did nothing to protect Navajo miners (or other miners, either).  It is unlikely that anyone depicted in those photos is alive today.

"Mine memory - Navajo miners work the Kerr-McGee uranium mine, 7 May 1953. Today, uranium from unremediated abandoned mines contaminates nearby water supplies. image: AP Photo" (borrowed from ehponline.org) This photo is very close to the one used by Prof. O'Neill. It may have been taken at nearly the same time. If you know of any survivors from this photo, please advise.

At a refining facility on the Navajo Reservation, highly radioactive wastewater was stored behind an inadequate earthen dam.  The dam broke, and the wastes flowed through a town and into local rivers.  Contamination was extensive.

Attempts to collect for the injuries to Navajo miners and their families were thrown out of court in 1980, on the grounds that the injuries were covered under workers compensation rules (where injury compensation was also denied, generally).

Navajos organized to protest the power plant. One wonders whether they can win it.

Sen. McCain seems cock sure that radioactive wastes won’t kill thousands of Americans in the future as they have in the past.  The uranium mining and uranium tailings issues occurred in Arizona, the state McCain represents.  Does he know?

We regard ourselves in the U.S. as generally morally superior to “those godless communists.”  Can we demonstrate moral superiority with regard to development of peacetime nuclear power, taking rational steps to protect citizens and others, and rationally, quickly and fairly compensating anyone who is injured?

That hasn’t happened yet.

When [uranium] mining [on the Navajo Reservation] ceased in the late 1970’s, mining companies walked away from the mines without sealing the tunnel openings, filling the gaping pits, sometimes hundreds of feet deep, or removing the piles of radioactive uranium ore and mine waste. Over 1,000 of these unsealed tunnels, unsealed pits and radioactive waste piles still remain on the Navajo reservation today, with Navajo families living within a hundred feet of the mine sites. The Navajo graze their livestock here, and have used radioactive mine tailings to build their homes. Navajo children play in the mines, and uranium mine tailings have turned up in school playgrounds (103rd Congress, 1994 ).

Think of the story of Techa River as a warning.

Malaria/DDT Carnival addendum

October 11, 2008

It’s almost as interesting that these posts show up on the same day, as what they say.

Following on the heels of the impromptu Malaria/DDT carnival earlier in the week, take a look at these posts:


Carnival of Fighting Malaria (and DDT)

October 8, 2008

It’s been about a year since the first, completely impromptu Carnival of DDT.  Last fall, in October and November, there was enough going on about DDT to merit something like a blog carnival, with a second in November.

My news searches today turned up a number of items of interest in DDT and fighting malaria — enough to merit another summary post, IMHO.  Here goes.

First, Tim Lambert at Deltoid sets straight the history of the policy of the World Health Organization (WHO) with regard to DDT use, and whether WHO caved in to pressures from environmentalists to completely ban DDT, as Roger Bate had earlier, erroneously said.  Tim has a number of well-researched, well-reasoned posts on DDT and health; people researching the issue should be sure to visit the archives of his blog.  But for today, make sure you read “Roger Bates’ false history.

This Friday the Hawk Mountain Sanctuary presents an award to Tom Cade, the Boise, Idaho guy credited with doing much to save the endangered peregrine falcon. You can read about it in the Allentown, Pennsylvania, Morning Call.

Cade played a major role in reviving the nearly extinct peregrine falcon in the 1970s. As a graduate student, he studied how a pesticide contributed to their sharp population decline. He eventually founded a conservation group, The Peregrine Fund, which reintroduced captivity-bred birds to the wild.

. . . The falcon’s revival is widely considered one of the most successful recoveries of an endangered species. The species teetered on the brink of extinction in 1970, when as few as 39 known pairs of nesting falcons existed. A 2003 survey puts the number of nesting pairs at more than 3,100.

On Thursday Cade will receive the Sarkis Acopian Award for Distinguished Achievement in Raptor Conservation.  According to The Morning Call, “The award is given infrequently by Hawk Mountain officials and is named after the Kempton-area bird sanctuary’s primary benefactor, a late philanthropist who studied engineering at Lafayette College.”

Also, see this story about the recovery of peregrines in Canada, from the Sudbury Star.

Bug Girl tells the story of a new documentary on the Michigan State University professor who documented the deaths of songbirds made famous in Rachel Carson’s book, Silent Spring. Dr. George J. Wallace’s work became the subject of an article in Environmental Journalism in 2005.  Students and faculty at MSU’s Knight Center for Environmental Journalism produced the movie, “Dying to Be Heard.”  Be sure to check out the comments at Bug Girl, for more information.

International health care expert César Chelala argues that the “War Against Malaria Can Be Won, Without DDT” at the on-line Epoch Times. Chelala reports on a project in Mexico — where DDT use has never stopped since 1946 — a project now extended to other places in Central America, demonstrating that the tried and true methods of preventing mosquitoes from breeding and avoiding contact work well to fight malaria.  Plus, he says, it’s cheaper than using DDT.  Doubt that it could work?  Chelala points out that the Panama Canal could not be dug without controlling mosquito-borne illnesses, and the Canal was opened in 1914, 25 years before DDT was demonstrated to be deadly to insects, more than 30 years before widespread deployment of DDT.

Early detection and treatment is critical to eliminate the parasite carriers. An important aspect of this project has been the collaboration of voluntary community health workers who are taught to make an early diagnosis in situ and to administer complete courses of treatment not only to those affected but also to the patients’ immediate contacts.

The project was carried out in specific pilot areas called “demonstration areas” which had been selected due to their high levels of malaria transmission. In those areas, the number of malaria cases fell 63% from 2004 to 2007. In several demonstration areas I visited in Honduras and Mexico as a consultant for the Pan American Health Organization malaria had practically been eliminated. Plans are underway to expand the project to other regions where malaria remains a serious threat.

One of the advantages of not using DDT (besides avoiding its toxic effects) is the enormous savings realized from discontinuing its routine use. These savings can now be put to good use with other diseases.

You might also want to view Chelala’s description of solutions for public health crises in Africa, at The Globalist.

Chelala’s cool, clear and accurate reporting sadly contrasts with the hysteric and wrong reporting at Newsbusters and other polemical outlets on the web, seemingly bent on perpetration of the hoax that DDT is harmless and Rachel Carson was wrong.

Liz Rothchild’s one-woman play about Rachel Carson, “Another Kind of Silence,” got good reviews upon opening at the Warehouse Theatre, in Croydon, England.

Meanwhile, from Uganda comes news that DDT spraying failed to reduce malaria in spraying done in that nation. Proponents expected a sharp and steep decline in malaria, but numbers are not greatly reduced.  Even after taking account for the legal difficulties of spraying, after conservative businessmen sought an injunction to stop DDT use, the results do not speak well for DDT’s effectiveness.

Contrary to expectations, data collected by health departments in Apac and Oyam districts, which record the highest malaria incidence in the world, do not reflect significant improvements since DDT spraying ended prematurely. From May to July 2008, which is the period immediately following the spraying, between 400 and 600 clinical malaria cases per 100,000 of the population were reported per week in Oyam; and 600 to 800 such cases in Apac for the same period. These are almost exactly the same as the number of cases reported between January and April 2008.

Getting news out of Africa is not always easy.  Reading reports from Ugandan papers, it becomes clear that reporting standards differ greatly from the U.S. to Uganda.  Still, the saga from Uganda demonstrates that DDT is no panacea.  Uganda is a nation that had not used DDT extensively prior to the mid-1960s.  Resistance to use now comes from tobacco and cotton interests who speciously claim that potential DDT contamination of crops would result in the European Union banning vital Ugandan exports.  The legal issues all alone assume Shakespearean tragedy dimensions.  Or, perhaps more accurately, we could call the story Kafkaesque.

Happily, we have evidence that younger people show concern about DDT pollution, in a story about the stuff in Teen Ink magazine.

A study in the UK finds DDT present in colostrum, the vital pre-milk substance newly-lactating mothers create for their babies, as well as in later breast milk.

Bed bugs continue their own surge on Americans, and knee-jerk writers editorialize for the return of DDT, completely unaware that bed bugs are among those critters most resistant to DDT, and unaware that there are other, more effective solutions.

James McWilliams writes in The Texas Observer that most of us are ecological illiterates, which makes control of pollution more difficult, in a review of a new book, The Gulf Stream. Canny readers will recognize McWilliams as the author of the recently-published book, American Pests: Our Losing War on Insects from Colonial Times to DDT.

Sandra Steingraber will lecture on November 11 in Philadelphia on “The Many Faces of DDT,” part of a series of lectures sponsored by the Chemical Heritage Foundation, “Molecules That Matter.”  Steingraber is the author of Living Downstream:  An ecologist looks at cancer and the environment.

Canada’s Leader-Post reports that Chinese food processors have been caught using DDT in food to reduce insect infestations.  The cycle starts all over again.

Time for this carnival’s midway to shut down for the night.  Don’t let the bed bugs bite.


Hope is the things with feathers

September 11, 2008

The Singing Cricket noticed that, with DDT use in decline, a lot of birds can be seen that we didn’t see for a long time. She takes hope at that thought.

Nice photos, too.

Apologies to Emily Dickinson, of course.

An account of bioaccumulation of pesticides — dangers of DDT explained

August 14, 2008

Even short-time readers know of the problems of DDT advocates, denialists who seen to think we can poison our way to health — or worse, that we can poison others, in Africa, to health.

Here’s a voice from the other side, an Australian anti-pesticide, go-back-to-nature site, that tells a dramatic story from California:  The Permaculture Institute, “Pesticides, and You.” Clear Lake offered a dramatic example of the dangers of bioaccumulating chemicals, especially pesticides like DDT.

Without endorsing everything this group urges, I will say the clear, simple explanation of the events at Clear Lake is accurate, worth reading, and worth remembering.  It’s what Rachel Carson sounded the alarm to warn us about, and but for the movement spurred partly by her book, Silent Spring, it’s what we would have faced at countless other locations.

African nations back off of limited DDT use

August 7, 2008

Anti-DDT business interests appear triumphant, if only temporarily,  in their efforts to stop the use of DDT in the fight against malaria.

ProtectAfrica.com reports use of DDT has been stopped in northern UgandaNine corporations sued to stop the sprayingNew Visions reports a shift to a chemical named ICON for use in Indoor Residual Spraying, designed to protect people against mosquitoes in their homes.

I have links to stories saying Rwanda has abandoned DDT in the past few weeks, but none of the links work.

Meanwhile, from The East African in Nairobi, Kenya, comes the report that Tanzania became the first East African nation in recent years to use DDT for limited, indoor spraying. [But be wary of this source; the article also claims many nations outlawed DDT after 1972; not accurate in Africa, nor most other places.]

There is high irony in businesses opposing the use of DDT when environmental organizations in other nations do not oppose it.


Thought of the moment: Environmental movement most diverse

August 6, 2008

Environmentalism is the most politically diverse movement in history. Here in the Kingsnorth climate camp, I have met anarchists, communists, socialists, liberals, conservatives and, mostly, pragmatists. I remember sitting in a campaign meeting during the Newbury bypass protests and marvelling at the weirdness of our coalition. In the front row sat the local squirearchy: brigadiers in tweeds and enormous moustaches, titled women in twin sets and headscarves. In the middle were local burghers of all shapes and sizes. At the back sat the scuzziest collection of grunge-skunks I have ever laid eyes on. The audience disagreed about every other subject under the sun – if someone had asked us to decide what day of the week it was, the meeting would had descended into fisticuffs – but everyone there recognised that our quality of life depends on the quality of our surroundings.

The environment is inseparable from social justice. Climate change, for example, is primarily about food and water. It threatens the fresh water supplies required to support human life. As continental interiors dry out and the glaciers feeding many of the rivers used for irrigation disappear, climate change presents the greatest of all threats to the future prospects of the poor. The rich will survive for a few decades at least, as they can use their money to insulate themselves from the effects. The poor are being hammered already.

What if we’re wrong about global warming? Bob Park sez . . .

July 25, 2008

4. UNCOOL: LOT OF HEAT FROM GLOBAL-WARMING DENIERS.
Suppose, I asked myself, that the deniers are right and the CO2 thing is a mistake? What will happen if the world takes the CO2 thing seriously, adopting common sense measures to counter anthropogenic warming and there never was any warming in the first place? 1) there will more non-renewable resources to leave to our progeny; 2) we will breath cleaner air and see the stars again, the way we saw them half a century ago; 3) we could stop paving over the planet, and 4) cut down on the number of billionaires. If we’re wrong we could have a party. We could have a party either way.

News from Uganda? DDT, cotton, misreporting

July 13, 2008

In continuing efforts to slam environmentalists and Rachel Carson, Instapundit and RWDB complain (whine?) about the European Union’s efforts to block the importation of cotton from Uganda on fears of DDT contamination.

Meanwhile, back in Kampala, the news is that the EU has done the opposite, and is encouraging the use of DDT officially, not blocking its use at all. If DDT is used to fight malaria and not in uncontrolled agricultural use simply to keep products blemish-free, in carefully-controlled sprayings, EU has no complaints.

Is there any western news agency with a stringer in Kampala who could chase this story down? Beck and Reynolds still offer no evidence to back their odd claims, but the story could sure benefit from a solid chunk of reporting from BBC, or Reuters, or Agence France Presse, or someone who could talk with the EU and Uganda officials.

Instapundit screws up again (Uganda, cotton, DDT)

July 5, 2008

Instapundit loves to roil waters, but he’s low on content, and everytime I see it, low on accuracy, too.

This is the entirety of Glenn Beck’sReynolds’s post linking to the rabidly anti-Rachel Carson, RWDB with a rant about DDT that lacks several key points of accuracy:

THE HIGH COST OF fighting malaria.

Six words and he’s wrong already. That’s quite a skill to be dead wrong in six words.

Our friend, Mr. Beck, at RWDB, has a news report from Uganda, and rather than note it and check for accuracy, he uses it as a tee for numerous shots and mulligans against science, scientists, environmentalists, health care workers, the EU, and anyone else who inhabited his latest delerium.

The story out of Africa is that a buyer of organic cotton refused to buy Ugandan cotton due to DDT contamination. True to the line of recent events, it’s not environmentalists who do anything , though the news story finds a way to blame them in the last paragraph. Instead, it’s a businessman.

But here are problems with the story:

  • There is no indication EU has anything to do with this failed purchase.
  • There is no indication that any environmentalist ever played a role — this is a Dutch purchasing company, shopping for organic cotton.
  • There is no indication that Uganda farmers can’t sell their cotton to other buyers.
  • There is no reason to presume that the cotton must be sold as “organic.”
  • There appears to be no indication of any DDT contamination.
  • It’s illegal to spray DDT on cotton in Uganda, as I understand it — if this cotton is contaminated, the problem is that DDT was diverted from malaria control. That’s not a problem for environmentalists — and, according to the PAN story cited above, farmers have incentives to keep it from happening.

Are we to believe that marauding anti-insect people roam Uganda, forcing farmers to steal DDT from health authorities and spray it on their cotton instead, against the farmer’s better interests?

Neither Glenn BeckReynolds at Instapundit nor the other Beck at RWDB bothered to check the facts, nor even to see whether the first face story passes the smell test. Where would DDT contamination come from? Why would a buyer refuse cotton if there’s no DDT contaminant? Why wouldn’t there be tests? Where are the test results? If EU is so down on DDT on cotton, where is the document that says so?

The company in the news story, ineptly named as it is, Bo-Weevil, does exist, it appears, either there or in the Netherlands. That surely is not the only cotton buyer for the EU. The first BoWeevil isn’t an EU company, since it’s headquartered in Tennessee. From their website:

Welcome to Bo-Weevil Eco Sportswear Mfg. LLC., nestled in the hills of Tazewell, Tennessee.

Producers of the most earth friendly clothing on the planet.

Bo-Weevil Eco started manufacturing and supplying clothing with one main vision: “Provide our customers with the highest quality clothing that integrates current fashions with timeless style, to create lifestyle clothing that brings awareness to care what you wear.”

We are a company that practices to restore, maintain and enhance ecological harmony. Doing so by being at the forefront of U.S.A. factories producing a line of women’s, men’s, kids and k-9 apparel made by pre-consumer recycled fibres. We are working to create change in the textile industry; to offer one step on the path to more sensible and sustainable use of resources in the production of basic commodities.

So, how does the EU get into this story at all? The second company, I can find listed only through a post at Pesticide Action Network, a source that is not always reliable on such issues.

Smell test: Does this sound accurate to you? When was the last time you saw anyone at Wal-Mart demand organic cotton?

The use of DDT has now affected cotton prices in the region. Patrick Oryang from Lango Cooperative told All Africa, “We are buying cotton at sh500 per kilogram instead of sh750. The country will lose about US$20 million because EUREP-GAP, an EU exporters body, has suspended buying products from the region because the consumers in Europe and America want purely organic products.”

What’s the real story?

Neither Beck nor Reynolds seems to care. They get a dig at environmentalists, so what if Ugandans get malaria?

Update, sorta: News from Uganda, in New Vision, seems to indicate that the EU has okayed the wise use of DDT in Uganda, contrary to claims of an EU ban (July 10 story). You can’t help but wish there were some good, clear reporting of this issue, from BBC or Reuters, or someone in Kampala besides these few, shallow news dailies.


Suzuki: 50 years of science makes a difference

June 27, 2008

Dr. David Suzuki is a Canadian scientist who writes popular science chiefly for Canadians. We in the U.S. might do well to pay more attention to him.

Below, his e-mail newsletter/column, with observations about the 50 years of science progress since his graduation from college. FYI.

Dear Friend:

Here’s your weekly Science Matters column by David Suzuki with Faisal Moola.

What a difference 50 years makes

Last month, I attended the 50th anniversary of my college graduation. A week later, I celebrated my grandson’s graduation from high school. I don’t think I was much different from the kids in my grandson’s class when I went away to college in 1954 (give or take a few rings and tattoos). Like them, I was filled with trepidation but also excitement about testing my physical and intellectual abilities beyond high school. But my how the world has changed in 50 years!

I began my last year of college in 1957. On October 4 that year, the Soviet Union electrified the world by successfully launching a satellite, Sputnik 1, into space. Little did we dream that out of the ensuing space race between the U.S.S.R. and the U.S.A. would come 24-hour television news channels, cellphones, and GPS navigation. In 1958, the only trans-Atlantic phone lines were cables laid on the ocean floor, so phone calls to England had to be booked hours or sometimes days in advance. I flew from Toronto to a roommate’s wedding in San Francisco on a propeller plane that made several stops during the 22-hour trip.

In 1958, scientists were still debating about whether genetic material was DNA or protein, we didn’t know how many chromosomes humans have or that the Y chromosome determines sex, and the Green Revolution was yet to come. Polio was still a problem in North America, smallpox killed hundreds of thousands annually, and oral contraceptives, photocopiers, personal computers, colour TV, and DVDs didn’t exist. In 1958, parts of the Amazon, Congo, and New Guinea had not been explored. We were yet to learn of species extinction, depletion of fish in the oceans, the effects of CFCs on the ozone layer, acid rain, global warming, PCBs, and dioxins.

In half a century our lives have been transformed by scientific, medical, and technological advances, as well as a host of environmental problems. No one deliberately set out to undermine the planet’s life-support systems or tear communities apart, but those have been the consequences of our enormous economic and technological “success” over the past five decades. Beset by vast problems of wealth discrepancy, environmental issues, poverty, terror, genocide, and prejudice, we are trying to weave our way into an uncertain future.

I began speaking out on television in 1962 because I was shocked by the lack of understanding of science at a time when science as applied by industry, medicine, and the military was having such a profound impact on our lives. I felt we needed more scientific understanding if we were to make informed decisions about the forces shaping our lives. Today, thanks to computers and the Internet, and television, radio, and print media, we have access to more information than humanity has ever had. To my surprise, this access has not equipped us to make better decisions about such matters as climate change, peak oil, marine depletion, species extinction, and global pollution. That’s largely because we now have access to so much information that we can find support for any prejudice or opinion.

Don’t want to believe in evolution? No problem – you can find support for intelligent design and creationism in magazines, on websites, and in all kinds of books written by people with PhDs. Want to believe aliens came to Earth and abducted people? It’s easy to find theories about how governments have covered up information on extraterrestrial aliens. Think human-induced climate change is junk science? Well, if you choose to read only certain national newspapers and magazines and listen only to certain popular commentators on television or radio, you’ll never have to change your mind. And so it goes. The challenge today is that there is a huge volume of information out there, much of it biased or deliberately distorted. As I think about my grandson, his hopes and dreams and the immense issues my generation has bequeathed him, I realize what he and all young people need most are the tools of skepticism, critical thinking, the ability to assess the credibility of sources, and the humility to realize we all possess beliefs and values that must constantly be reexamined. With those tools, his generation will certainly leave a better world to its children and grandchildren 50 years from now.

USAID allows DDT use in Africa

June 25, 2008

Africa Science News Service reports that USAID signed a contract that allows U.S. money to be used to purchase DDT for Indoor Residual Spraying (IRS) against malaria-carrying mosquitoes.

If so, this is one of the final barriers to use of U.S. funds for DDT use. Oddly, the news report offers no details on when or where the contract was made.

DDT use in Uganda was halted pending a suit by Uganda agricultural businesses to stop the spraying. The contract discussed would allow purchase of other insecticides to be used in place of DDT for IRS.

It’s important to note that no environmental organizations have expressed opposition to the limited use of DDT in IRS applications. It may be significant to note that the programs involving indoor spraying fall into the category of integrated pest management, which is what Rachel Carson urged in her 1962 book, Silent Spring.
