ChemBark

A friend on Facebook brought my attention to a very interesting article from NBC News:

People always worry about pee in the pool, but number two is the No. 1 problem, government health experts say. They found plenty of evidence that someone’s pooping in the pool. It’s not only disgusting, but it’s evidence that people are not following basic hygiene rules, says Michele Hlavsa, chief of the Centers for Disease Control and Prevention’s Healthy Swimming Program.

“It is time to stop treating the swimming pool as a toilet,” Hlavsa told NBC News. “Nowhere else except for the pool is it acceptable to poop in public or pee in public. In other places if we did this in public, we’d be arrested.”

The pool-poo expert went on to say:

“The average person has about .14 grams of feces on their rear end,” Hlavsa said. “If that rinses off into the water, the amount from one person might not be that much. But as more and more swimmers introduce it that much, it does become an issue.”

She’s actually done the math.

“Let’s imagine 1,000 kids go to a water park. They have as much as 10 grams of feces on their rear ends,” she said.  “We are now talking about 10,000 grams or 10 kg. That translates to 24 pounds of poop in the water.”

I am willing to grant Hlavsa’s obscenely high estimate of 10 grams of poo per bottom—which does lead to 10 kg of poo per 1000 bottoms—but that does not equate to 24 pounds! The correct conversion factor for poo (or any other substance at the surface of Earth) is 2.2 pounds per kg.

I am immensely relieved her hypothetical pool contains only 22 lbs. of poo.

Tom Barton won last year’s ACS national election for President (and was kind enough to answer our questionnaire about important issues facing the society). Yesterday, President-Elect Barton asked that I share this message with the readers of the blog:

In my ACS presidential year of 2014 I’m considering hosting a symposium on fracking with, of course, emphasis on the involvement of chemicals.  I would appreciate hearing from anyone suggestions for particular areas for inclusion, and potential speakers.  I seek a balanced set of presentations from experts in the various aspects, and would certainly be interested in any germane research.  I myself am not an expert in this arena, but I am trying to get smart in it.  In advance, I appreciate your assistance.

Feel free to weigh in using the comments. I will leave the first…

I was amused by a news story out of Florida, where a pair of disc jockeys were suspended after going on the radio Monday (April Fools’ Day) and reporting that the local water supply had dihydrogen monoxide in it. Unaware that dihydrogen monoxide is H₂O, and H₂O is water, many residents went crazy:

 

As if we needed any more evidence that science education in this country is absolute crap.

What’s more, the DJs might face felony charges. From a legal standpoint, I’m interested in seeing how this one turns out. I haven’t heard any direct quotes from the broadcast, but can you charge someone with a crime for stating a scientific fact? I’m assuming they were careful and said something along the lines of “there’s dihydrogen monoxide in the water” as opposed to “the water is poisoned with dihydrogen monoxide.” Anyway, I suppose the DJs went in with a fair amount of mens rea; what else did they expect to happen?

Hey, look what the American Chemical Society produced for St. Paddy’s Day: it’s a tutorial on the chemistry of alcohol, including its effects on your body and how your body attempts to rid itself of the poison.

 

Uh oh, but there’s a WWWTP? in there. If you pause at the 2:45 mark, you can see that they flubbed the structure of “amyl alcohol”:

 

While there are several isomers of amyl alcohol, instead of drawing one of those, the ACS has shown the structure for isoamyl acetate (commonly known as banana oil). When banana oil is dilute, it kind of smells like Juicy Fruit bubble gum. In concentrated form, it smells really gross. I know, because I made it in 6th period orgo lab in high school and the people around me in 7th period religion paid the price.

But good effort, ACS! This is exactly the sort of info we (as chemists) should be communicating to the People. It’s news they can use. Of course, in the future, try to get the structures right! (And for the record, you also misspelled “judgment” at 0:49. Boo.)

H/T to Kim the Magnificent for the tip.

The annual ScienceOnline 2013 conference is taking place in North Carolina, and chembloggers Carmen Drahl and Dr. Rubidium are running a session tomorrow on chemophobia. You can follow updates on Twitter labeled with the hashtag #chemophobia.

Personally, I think the greatest failure of our field over the past three decades has been the steady decline of the public image of chemistry. Our “brand” has steadily deteriorated from an apex of “better living through chemistry” in the 1970s to the ever-worsening current climate where “chemicals are bad” and products are nonsensically advertized as “chemical-free”.

There certainly are cases where specific chemists and chemicals have had horrific consequences for the public (e.g., thalidomide or the Bhopal disaster), but surely these cases are balanced by the numerous ways that chemistry has improved modern life: from countless new pharmaceuticals that improve health to a wide array of new materials that make modern technology possible. That’s all “chemistry” and “chemicals”, but the average person-on-the-street would probably not associate these advances with our science.

Of course, this is a blog for chemists, so there’s no sense wasting time here celebrating all of the benefits of chemicals and chemistry. Rather, why don’t we focus on how utterly stupid our field is with regard to communicating these benefits? Despite the manifestly dire state of the public image of chemistry, chemists continue to do nothing to correct the problem.

But, Paul…is it really a problem? Who cares if the public dislikes chemicals? So long as chemists know better, we will continue doing good science. Why should we be distracted by general ignorance?

The problem with that argument is that we live in a democracy. For a democracy—where the People govern by voting—to function efficiently, the electorate must be educated and informed. The steady decline of chemistry’s public image is a massive problem, because it erodes support for our field. Taxpayers fund our research, and if they are convinced that not only is chemistry not helping the world, it is hurting it, then what is going to stop politicians from cutting funding? This is already occurring. Look at how many Americans vilify scientists who support the highly (un)controversial theory of evolution. We also spend many, many times more money on the DoD than scientific research because the public is generally much more concerned about the threat of foreign dictators than the combined threats of insidious disease and the global energy crisis. Seem stupid? Well, turn on the news tonight. What are people talking about, the Middle East or cancer? And what’s worse than people not knowing anything about chemistry is when they “know” incorrect negative information about chemistry. That’s basically where we are.

Hey Paul, isn’t this something the ACS should handle?

Yes! Actually, it is something all of us should take responsibility for handling to some degree, but the ACS should be at the forefront. This brings me to the point: WHAT THE HELL HAS THE ACS BEEN DOING FOR THE PAST 30 YEARS? As far as I can tell, very little in the public-image battle, and the miserable status quo is all the evidence you need that our professional society has failed its mission in this regard.

OK, wise guy, what should the ACS be doing?

I can think of a number of things, but let me give you two: one from the executive level and one from the grass-roots level. First, the ACS needs to get a handle on misinformation in the media. When someone blurts “chemical-free” into a microphone or opines about the hazards of a compound with zero supporting evidence, the ACS should have someone step up and provide a rebuttal. We need a “war room” at ACS headquarters that monitors all major media outlets and contacts editors and producers when something is wrong. The war room should have experts trained in public communication who are camera-ready 24 hours a day and a TV studio on-site for satellite interviews. Reporters are getting lazier; we must adapt. At the grass-roots level, the ACS needs to do a better job organizing outreach efforts and coordinating volunteer chemists to run these programs. More on that below.

Whoa. Volunteer chemists and outreach programs? What are you talking about?

I think it is important that every chemist spend some time engaging the general public for the purposes of education and promoting the benefits of our field. Let me toss out a ball-park figure: 5% of your time allotted to chemistry.

You want me doing what, exactly?

Pretty much anything where you are bringing science/chemistry to a population not already intimately involved in the field. I am not talking about writing essays for Angewandte or leaving comments on In the Pipeline. I am talking about: (1) judging kids’ science fairs, (2) writing letters to the editors of newspapers to correct misinformation, (3) running or volunteering at a local science club, (4) explaining your research at a science cafe, (5) volunteering to talk to a middle-school science class, (6) developing a lab exercise for high schoolers based on your research, (7) making a science Web site for a general audience, (8) making YouTube videos pretending you are “Phil Nye the Chemistry Guy”, (9) editing Wikipedia, (10)…   need I go on? Anything. Anything! There are thousands of possibilities. If you don’t think you have a good idea, other people should have plenty of ideas in need of volunteers.

You think this will work?

Yes. I believe it will help. I think that education and outreach, or “E & O” in NASA parlance, is exactly what kept a largely overpriced set of shuttle missions in operation for so long. Spacemen realize that they need the public on their side, so they appeal to the public. I assume astronauts on space stations have more important scientific activities they could be doing than giving interviews to the yentas on The View, but NASA has the big picture in mind. If NASA could keep the space shuttles up so long, think about all of the additional funding we could bring to a field of science that is much more successful at improving people’s lives.

What’s in it for me?

Lots of things: (1) you’ll become better at communicating and teaching technical material, (2) you’ll feel good having taught someone something, (3) you’ll be giving back to society – was there a role-model or teacher when you were young that made you want to pursue a career in science?, (4) you are making the world less dumb, one person at a time, (5) in thinking about fundamental concepts and how to explain/teach them, you will invariably come up with new ideas. Sometimes it’s nice to think about areas of chemistry outside your focus of research, (6) you will help to improve the funding climate by persuading voters chemistry is valuable.

Bah. Those are worthless. I can’t list those on my CV!

Actually, you can list outreach activities on your CV. They may even make you seem human, you robotic hardass.

Seriously, my boss/advisor won’t care. Actually, I’ll get in trouble because he views them as a waste of time.

Public engagement should be a shared responsibility. Perhaps the reason almost nobody pitches in is because “why should I do it if the guy over there doesn’t?”  We need to find ways to incentivize desired behavior. Maybe a small outreach component for Ph.D. theses? Maybe make it part of tenure packages?

But Paul, I went through 11 years of university training to become a high-powered research machine. I am God’s gift to chemical research. I can think of nothing more inefficient than removing me from the bench to muck around with third-graders. Can’t we just hire professional outreach people so I can be left alone?

First, you are going to be able to bring things to the table that an education professional would not. Second, if you are truly “God’s gift to chemical research”, then you are a rock star. People love rock stars of any field. That is why we are willing to watch events like curling in the Olympics. You will be a great help! Also, get over yourself! Astronauts frequently give interviews while working in space. I assume there are probably some experiments they could be doing, but NASA recognizes the importance of education and interacting with the public.

Paul, I am too busy, go away.

What if everyone were too busy? Everyone is too busy! You can make a little time for this. C’mon.

Paul, I am still unconvinced this is actually worth my time.

Fine. You are a selfish jackass. I hope there are enough good chemists out there who can make up for your dereliction.

 

Folks, if we don’t start getting serious about addressing chemophobia, we are going to find ourselves in a bad, bad place as a profession, and the consequences for mankind won’t be pretty either.

 

This summer, our NSF-funded center for solar-energy research joined forces with a local high school and a local science club to create a new program for informal science education in western Los Angeles. I serve as the coordinator for Caltech’s participation in the program, which involves helping to plan and run science club meetings every other Saturday for 8-to-14 year-olds at a housing unit on the west side of Los Angeles. We structure our meetings less like a class and more like a club by favoring the use of hands-on activities where the kids can actively discover the concepts we wish to teach (and have lots of fun at the same time).

As you might expect, one of my primary concerns has been making sure the kids run these activities safely. When designing experiments, there are a number of top-level considerations that go into addressing safety. First, we avoid designing any experiments with serious hazards—we don’t use especially toxic chemicals and we limit the scale of our activities to small volumes. Second, we have a fabulous team of “near-peer” mentors from the high school and Caltech who make sure that the kids aren’t performing any unauthorized experiments (like tasting the chemicals we use). Finally, we are actively working on building good habits with respect to personal protective equipment (PPE).

Before Caltech joined the program, the kids already had a shared set of goggles for general use when activities warranted. One of the first events we organized for the club was a field trip to Caltech to tour the school and see what we “real scientists” do in the lab. Before they came into my room to see a few demonstrations, I gave them a quick version of my lab accident story along with the requisite speech on the importance of wearing goggles when in laboratory. With this story freshly in mind, they all lowered their goggles over their eyes and marched in (see photo, above).

Sadly, despite my impassioned plea, it took all of two minutes before some of them started moving their goggles up to their foreheads. Two minutes! I know goggles are a drag—they can feel tight, fog up, and block your vision—but I was hoping for a little more after my attempt to scare them straight.

One of the most important things I’ve learned from my involvement in the new program is that it is really, really hard to get kids to pay attention to you. If you try to lecture them about a concept, you’ve got about ten seconds before their eyes start wandering across the room. It’s far better to get them learning concepts by running experiments and/or having them ask and answer questions. Kids at this age are not especially concerned about what you want them to do—they seem to do what they want to do.

And I think that was part of the problem with the goggles. We wanted the kids to wear them, but that missed the point. What would make the kids want to wear them? Obviously, a cautionary tale about preserving their eyesight in the unlikely event of an accident was not enough.

I thought we needed to do a better job of making eye protection cool/fun, so first, we ordered them some safety glasses like “real scientists” wear (for general use) in lab. I bought three varieties of glasses from my favorite safety company. Each pair was only about $2—well worth the investment. At the next club meeting, we let the students choose what model and color they wanted. (To my surprise, the boys all wanted red frames while the girls opted for the black or clear frames.) Finally, in order to let the kids establish a personal connection to their PPE, we brought some knickknacks to let them personalize their glasses. These included rolls of colored tape and packets of jewel stickers that the kids could use to “bling out” their frames. This model had particularly wide frames that gave the kids a bunch of space to decorate.

Right after the decoration activity, we performed our most demanding (and fun) activity to date: making glow sticks from scratch. I don’t think I saw a single kid remove his/her glasses during the experiment. We’ll keep monitoring the situation in the future, but I think we’ve made some headway.
