The results are in, and it turns out I'm a walking cocktail of toxic chemicals. I've got a jigger of lead in me, a splash of flame retardant and a dash of DDT.
But none of this came as a surprise, and before you take pity, let me remind you that your organs are probably marinating nicely too. We've all ingested and inhaled chemicals in our lifetimes, and some of them linger in the body for decades.
What's different in my case is that I've got the evidence right here in front of me, having participated in a bio-monitoring study two months ago with 10 other Californians who gave blood, hair and urine samples.
To be honest, there's little evidence of links between chemicals and specific diseases, and we don't know much about safe levels of exposure. Still, it was a little unnerving to read that I had the second-highest level of mercury among the 11 people tested. Have I eaten too much tuna?
Possibly, but my concern about mercury poisoning quickly faded when I ran my finger down the chart and realized I was leader of the pack, by a long shot, when it came to another chemical.
Ever heard of phthalates?
The chemical compounds, used in soap and shampoo and as a softener in plastic products, have been associated with cancers in rats and abnormalities in the reproductive systems of babies. In my group of 11 human guinea pigs, my mono-ethyl phthalate count -- one of several phthalates we were tested for -- was more than 40 times the median.
"It's surprising, but not unheard of," said Charlotte Brody of Commonweal. The Northern California health and environmental research group sponsored the study to call attention to our growing exposure to industrial chemicals, many of which are only partially tested before they're on the market.
Brody said there are suspected links between mono-ethyl phthalate and pulmonary problems, as well as low sperm counts. Seems to me I'm breathing just fine, though. And I've got a daughter who's not quite 2. It's quite likely my high count was a blip, because phthalates accumulate and pass through the body quickly, unlike, say, the DDT that's been in me since the pesticide was banned nearly 30 years ago.
"It could have been from something you were exposed to in the 48 hours before we tested you," Brody said. "It could have been in a deodorant, hair gel, anything with a fragrance. It could have been in a food container -- let's say a plastic wrap." One problem, Brody told me, is that you won't always find mono-ethyl phthalate listed as an ingredient.
"It might just say 'fragrance,' " she said, so you've got no idea that what you're smearing under your arms could lower your sperm count.
I checked out my long-lasting stick deodorant and read the ingredients. Dipropylene glycol, water, propylene glycol, sodium stearate, PPG-3 myristyl ether, triclosan, tetrasodium EDTA, hydroxide, D&C violet No. 2, D&C green No. 6, and -- voila! -- fragrance. So that could be it. Or it could have been my $1.99 shampoo and conditioner in one.
I'd never given it much thought, but you have to put a lot of faith in the chemical and hygiene industries -- along with federal regulatory agencies -- in exchange for "high endurance 24-hour odor protection." And now that I think about it, I had plenty of reason to be suspicious of a shampoo that promised "healthy and lustrous" hair even before I knew my phthalate level.
I also tested slightly above the median for perfluorooctane sulfonate, which used to be in Scotchgard and is still in textiles, leather protection products and cleaning agents. The suspected carcinogen may stay with us longer than DDT and PCBs.
So should I be worried about any of this?
I don't intend to lose any sleep, and far as I can tell, there's no need for me to go running to the nearest emergency room. The folks who sponsored the bio-monitoring cautioned us against being alarmed, even if the results "may be upsetting." As UC Riverside toxicologist Robert Krieger said when I last wrote about this subject, hard evidence of chemicals in our bodies is meaningless because we don't know what levels pose a health risk, and we may never know. Krieger has questioned the need for state Sen. Deborah Ortiz's (D-Sacramento) proposal to set up voluntary testing of California residents to monitor the presence and concentration of certain chemicals.
The bill has been viewed suspiciously by the California Chamber of Commerce, which is hyperventilating about the possibility that it could lead to chemicals being banned. Four other bills to regulate chemicals are pending in Sacramento, including one that would ban certain phthalates, calling into question the safety of everything from rubber ducks to plastic water bottles.
Are Commonweal and the authors of these bills overreacting? The correct answer is that we don't know, and that uncertainty is part of what's driving their efforts.
