Measuring Pollution In Humans 423
CHaN_316 writes "Scientists have begun measuring pollutants in our body and the results sound like a chemical clean-up site. They've found things such as flame retardants, chemicals derived from DDTs, mercury, uranium, cotinine, and many more. The concern is a lot of this stuff is ending up in mother's milk. But hey, at least in the event of spontaneous combustion, I'll be partially protected."

What your asking for is oversight, and audit... and frankly I agree with them. If you want to audit the quality of their work, you should pay for it. Also, I would think you'd want an independent 3rd party doing the work anyway. I do disagree with them about it costing dearly, I have a friend who works in a lab that does 'walk up' business on water, food and so forth and I wanna say, depending on the subject matter, its less then $100. If that is too steep (reasonable to me if trusting my water was important) I'm sure you could google your way to a reasonable home kit online.
Otherwise, I recommend buying bottled water in bulk or getting one of those 5 gallon dispensers.

I think Milloy's point, however, is that life expectancy has increased tremendously over the past hundred years, although medical advances probably greatly outweigh any negatives caused by pollutants.

I mostly believe the opposite. Remember that before the invention of tap water, people drank out of rivers and streams that ran over lead and mercury deposits and had animals (and people) shitting in them. We can tolerate a good deal of crud in the stuff we consume.
That's not to say that pure water isn't preferred, but I wouldn't go as far as to say that tap water is unfit for human consumption altogether.

Not true. Not even close. If they tried this the public would be all over them as the water would be completely impalatable and aesthetically appalling (algae and turbidity). The EPA would have a fit and require it to be corrected. If it wasn't, they would impose fines of up to $25K a day per violation.

Read the EPA regs - http://www.epa.gov/safewater/mcl.html There is no way in hell they are distributing untreated surface water. Bear in mind that Michigan probably imposes even stricter regs than the EPA.
Many people believe that public water sources are unsafe but they cannot say why. Is there something specific that concerns you?

A number of things. One of the more interesting here in the US was the ban on EDB (ethylene dibromide) back in 1983. This was a bit of a political fuss at the time, with farmers and commentators using the argument that "scientists hadn't been able to measure the danger" of this compound.
This has turned into a useful textbook example of "spin". I heard an article from NPR (National Public Radio) in which they talked about being curious about the claim, so they tracked down some of the scientists who had attempted to do such measurements. It turned out that they had done the usual tests to measure the concentration that killed 50% of their test animals. They failed. At one part per trillion, the lowest level that they could reliably produce, they lost nearly 100% of the animals. Autopsies showed that the critters died of multiple cancers. They commented that EDB was possibly the most powerful carcinogen yet discovered.
This wasn't exactly new news in 1983. Information on the biological efects of EDB date back to the early 1950's. There's a report [cdc.gov] online from 1974 that was obviously a preliminary study, of only 93 rats and 94 mice, some treated for only 12 days. The death rate of around 80% in this tiny study was a red flag that triggered further studies. It took another decade before a ban went into effect.
The farmers (or at least the farm-supply companies) really wanted to continue using EDB. Their PR depended on the fact that people would hear "scientists have been unable to measure the danger level" as meaning "EDB is so safe that
Decreasing this one compound in our food supply could well explain the slight decrease in overall cancer rate in the past decade. EDB is rather persistent in the environment, and underground water in a lot of farming areas was contaminated with it. But by the 90's, the concentration was starting to drop, and it's believed to be much lower now.
This story seems to be known in medical and statistical circles. It's generally unknown to the public. I never heard any hint of this part of the story from the mass media, where the story was generally presented as "controversial". The right-wing talk-radio types really publicised this as an example of heavy-handed government over-regulation of The Market. I've wondered occasionally whether the growing rabidity of their opposition to NPR had anything to do with stories like this.
Anyway, if you want a good example of how you can phrase things so that people make exactly the wrong inference, you might remember "scientists have been unable to measure the danger level".

Yours is the first time I've heard of a breastfed baby being jaundiced for longer than the first couple weeks (I'm assuming, you didn't say). It can't be that common.
Infant formula has its own laundry list of issues that crop up. Namely, recalls (contaminants getting into the final product) and digestive problems. Babies that have trouble digesting ANYTHING even after their first year of life, I've seen it several times with friends who formula feed but have never seen it with friends who breastfeed. I've also read that it is fairly common in formula fed babies to have the digestive problems.

I don't drink unfiltered tap water unless I have to. I usually drink distilled, and I shower and wash with tap. Some people have bad reactions to the stuff that's in water and that's them, personally I think everyone should drink distilled ideally but some people can't afford it, plus it takes a lot of energy to make distilled water. At least filter your water for the chemicals in it to reduce the amount that's in the water.
Re:this must vary enormously (Score:2, Informative)
There are some key parameters imposed ny the EPA that are universal. Most of us (public water supplies) try to exceed our state requirements which tend to be slightly more restrictive than the federal regulations. You are correct in saying that water quality from town to town does vary signifigantly but it is important to note that they all must meet the federal guidelines at a minimum. The differences in quality are usually aesthetic (discoloration, taste, odors)which is still very important as it is the most noticable. The water systems that people are pleased with have capital to build, improve and maintain. Those that don't have capital must get by with just "meeting the regulations". Good operators make all the difference in the world. Sometimes a problem that would require a significant expenditure on the part of the PWS (money they don't have in many cases) can be alleviated or at least lessened to a tolerable level by employees that care and are knowledgable.

low dose toxicity (Score:2, Informative)
take for example endocrine disruptors (substances that mimic hormones in your body). read this excerpt from the Chemical Messengers [That Work in Parts per Trillion] [mindfully.org] chapter in the book Our Stolen Future:
"What is astonishing about vom Saal's wombmate studies is how little it takes to dramatically change the tune. Hormones are exceptionally potent chemicals that operate at concentrations so low that they can be measured only by the most sensitive analytical methods. When considering hormones such as estradiol, the most potent estrogen, forget parts per million or parts per billion. The concentrations are typically parts per trillion, one thousand times lower than parts per billion. One can begin to imagine a quantity so infinitesimally small by thinking of a drop of gin in a train of tank cars full of tonic. One drop in 660 tank cars would be one part in a trillion; such a train would be six miles long.
The striking lifelong differences between a pretty sister and ugly sister stem from no more than a thirty-five parts per trillion difference in their exposure to estradiol and a one part per billion difference in testosterone. Using the gin and tonic analogy, the pretty sister's cocktail had 135 drops of gin in one thousand tank cars of tonic and the ugly sister's 100 drops-a difference that might not be detectable in a glass much less in a tank car flotilla.
This is a degree of sensitivity that approaches the unfathomable, a sensitivity, vom Saal says, "beyond people's wildest imagination." If such exquisite sensitivity provides rich opportunities for varied offspring from the same genetic stock, this same characteristic also makes the system vulnerable to serious disruption if something interferes with normal hormone levels-a frightening possibility that first dawned on vom Saal when Theo Colborn called him to talk about synthetic chemicals that could act like hormones."
some studies have even shown that as the dose is lowered toxicity increases and as the dose is increased toxicity approaches zero! this turns our traditional understanding of toxicity on it's head.
read these two issues of Rachel's Environment & Health News for an intro to toxicity:
