Polonium-210: A pretty good way to horribly murder somebody

Last week, a Swiss investigation found evidence to support the idea that Yasser Arafat was poisoned with polonium-210 — a radioactive element that's safe to carry around in a container, but causes unstoppable death if swallowed. NPR sat down with Deborah Blum, a science writer who specializes in the chemistry of poisonings, to talk about what makes polonium-210 a particularly handy way to off somebody and why it's so hard to bring a polonium poisoner to justice.

8 foods that aren't as frightening as Buzzfeed thinks they are

An actual chemist looks at claims made about "toxic foods" in a recent Buzzfeed linkbait post and calmly explains why the whole thing is ridiculous. Of the 8 foods (actually, mostly food additives) mentioned, one is hardly used anymore, another was withdrawn from the market two years ago, two only sound scary if you failed chemistry, and four have had their risks vastly overstated. It's the sort of situation where some studies show a risk, some studies don't, and there's good reasons to think the risk — if it exists — isn't that big, to begin with. Maggie

"Looney gas" and lead poisoning

Last week, Mother Jones published a really fascinating article arguing that the crime wave that swept through America between the 1960s and 1980s can largely be blamed on leaded gasoline — and the subsequent lead poisoning of an entire generation of Americans. For more background on the dangers of leaded gas, I suggest reading this post by Deborah Blum. Essentially, it's an excerpt from her fantastic book, The Poisoner's Handbook. In it, she tells the story of the history of leaded gas — a substance that was known to be dangerous even in the 1920s — and the conspiracy to sweep that danger under the rug. Maggie

Leaded gasoline and the 20th-century crime wave

Scientists are amassing evidence that suggests exposure to tetraethyl lead — the additive once used in almost all the gasoline sold in the United States — could account for the dramatic increase in crime that happened in this country between the 1960s and 1980s. As leaded gasoline was phased out, they say, children were exposed to less lead, leading to the decline in crime that began to really kick in in the 1990s.

This is the same curve of crime statistics that economist Steven Levitt, of Freakonomics fame, attributed to the legalization of abortion. Levitt's theory was that, after Roe v. Wade, there were fewer unwanted babies born into dire circumstances and, thus, fewer people to grow up on the path to criminal behavior. Levitt matched the rise in abortion rates to the decrease in crime, but frankly, there are a lot of things that you can correlate to the decrease in crime.

What makes the lead theory interesting is that correlations match not just at the national level, but at regional, and even neighborhood levels. Increases in lead relate to increases in crime — usually a couple of decades later. Likewise decreases in lead relate to later decreases in crime. What's more the same correlations exist in countries all over the world. Meanwhile, we know that lead has big impacts on growing bodies — it affects brain function, it's linked to hyperactivity, difficulty managing aggression, and lowered IQ.

Correlation isn't causation. But in this case they definitely seem to be winking suggestively at one another. Kevin Drum has an excellent piece on this at Mother Jones, working through a decade worth of research by multiple scientists that supports this disturbing conclusion. It really is possible that we, as a society, damaged a generation of children and caused a crime wave (not to mention the ongoing damage to kids that live in high-lead neighborhoods today).

Following a chain of unexplained deaths in Thailand

Over the past few years, multiple people have died in Thailand from what appears to be exposure to some kind of poison. Most of these people have been tourists. And most of them have been young women. The deaths have happened in clusters. Five or so on the island vacation hotspot of Kho Phi Phi. Another group of six at Chiang Mai's Downtown Inn.

Lots of possible explanations have been suggested — ranging from serial killers, to hallucinogenic beach drinks, to overuse of banned insecticides in hotel rooms. But, so far, none of the specific poisons proposed as the culprit totally makes sense in relation to the deaths. And, to make things worse, it seems like Thai authorities are doing their best to make it difficult to actually investigate what has happened in individual cases, and figure out whether the cases are linked or not. At this point, it's hard to even know whether all the people who have died exhibited the same symptoms.

Deborah Blum, a Pulitzer-winning journalist who has done a lot of reporting on poisons and true crime has been following this story and just published another piece on the still-unfolding mess.

Your daughter died.

Your daughter died thousands of miles from home. In a hotel where no one came to help. In a hospital where she struggled to keep breathing and just couldn’t. In a room where her heart – and somehow you still don’t really believe this – just stuttered to a stop. In a country, where authorities have failed for months, years even, to tell you how or why your daughter died.

Your daughter, you’ve come to realize, died in a pattern that links too many other young women, a chain of suspected poisonings over the last few years. Jill St. Onge, 27, of Seattle, Washington, and Julie Bergheim, 22, of Drammen, Norway, who both died in May 2009 on the southern island of Koh Phi Phi. Sherifa Khalid, 24, of Kuwait, who died 12 hours she spent a day on the same island in July of the same year.

The chilling history behind a museum's disembodied uterus

To be fair, there are really only a few ways that London's Hunterian Museum would end up with the uterus of a young woman floating in a jar. Given that the museum is home to surgical specimens, many of which were collected in the days before surgery involved anesthesia, it's easy to guess that the story behind the uterus is not a pretty one.

But at The Chiurgeon's Apprentice blog, we learn that the story is even more grisly than you might have suspected. In fact, it belonged to a woman who committed suicide by drinking arsenic in 1792. She was, at the time, a month or so pregnant. Medical historian Lindsey Fitzharris writes about the autopsy:

In his [autopsy] report, Ogle remarked that her stomach contained ‘a greenish fluid, with a curdy substance…an effect produced by the arsenic’. He also noted that there was ‘an uncommon quantity of blood in the vessels of the ovaria and Fallopian tubes’ and that it was ‘evident, from this circumstance, that conception had taken place’.Nevertheless, when told that the date of her last period had only been ‘a little more than a month before her death’, Ogle began to question whether Mary had been pregnant when she died.

Curious to know the truth, Ogle removed the ‘organs of generation’ and gave them over to the famous anatomist, John Hunter, whose interest in pregnant cadavers was well known. Hunter injected the arteries and smaller vessels of the uterus with a wax-like substance so that ‘the whole surface became extremely red’. The uterus was then split open and the ‘inner surface of the cavity…was examined with a magnifying glass’...

Poison, forensics, and how science protects us

Last month, I read Deborah Blum's The Poisoner's Handbook , a really fascinating book about poison and murder in the early decades of the 20th century. Primarily, Blum looks at the development of forensic science and how the New York City coroner's office transitioned from being a place to stash political flunkies to being a scientific and effective player in crime solving. But there's another theme to the book as well—without science, there are many crimes that go not just unpunished, but completely unnoticed.

And this isn't just about women offing their husbands or villains chloroforming unsuspecting strangers. As the coroner's office developed standards of research and became an entity that served justice, the people who worked there became increasingly aware of the ways that the powerful profited off poisoning average workers and consumers. From government agents intentionally lacing alcohol with deadly adulterants during Prohibition, to factory owners knowingly exposing their workers to dangerous chemicals, Blum's book is full of examples of public corruption that was only brought to light because coroners took the time to apply the scientific method to investigating and cataloging deaths.

Some of these stories are ones I'd heard before, but had no idea the role that coroners and forensics had played in exposing the crime and providing evidence that ensured the people harmed received justice. For instance, Blum has a couple of posts on her blog right now about tetraethyl lead—the lead in "leaded" gasoline. This additive fixed an obnoxious mechanical problem in car engines, but at the price of sending factory workers to their deaths in straight jackets.

In October of 1924, workers in the TEL building began collapsing, going into convulsions, babbling deliriously. By the end of September, 32 of the 49 TEL workers were in the hospital; five of them died.

In response to the worker health crisis at the Bayway plant, Standard Oil suggested that the problem might simply be overwork. Unimpressed, the state of New Jersey ordered a halt to TEL production. And then the compound was so poorly understood, state health officials asked the New York City Medical Examiner’s Office to find out what had happened.

In 1924, New York had the best forensic toxicology department in the country; in fact, it had one of the few such programs period ... It took Gettler three obsessively focused weeks to figure out how much tetraethyl lead the Standard Oil workers had absorbed before they became ill, or crazy, or dead. “This is one of the most difficult of many difficult investigations of the kind which have been carried on at this laboratory,” Norris said, when releasing the results. “This was the first work of its kind, as far as I know. Dr. Gettler had not only to do the work but to invent a considerable part of the method of doing it.

Working with the first four bodies, then checking his results against the body of the last worker killed, who had died screaming in a straitjacket, Gettler discovered that TEL and its lead byproducts formed a recognizable distribution, concentrated in the lungs, the brain, and the bones. The highest levels were in the lungs suggesting that most of the poison had been inhaled; later tests showed that the types of masks used by Standard Oil did not filter out the lead in TEL vapors.

Ultimately, the reactions to this research didn't go far enough, fast enough—the workers got better safety equipment, but Americans were still being exposed to tetraethyl lead in gasoline though the 1980s. But, without science, there would have been even less protection than there already was. The work of the New York City medical examiners forced government and business to pay attention to something they preferred to ignore.
