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.

        When you're expected to live to 75 and you're worried about the quality of the stuff that allows you to live that long, perhaps the problem is that you *ARE* living that long.

        This substance (H2O) has an even more obscure name in the IUPAC chemical naming system: "ozane" (H-saturated oxygen). It is so rarely used you can't even find it in Google.

        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.

      IAAAC (I am an analytical chemist) who worked directly with testing water samples from municipal water treatment facilities, schools, and private clients. The Clean Water Drinking Act of 1976 mandates standards for community water suppliers, including standards for lead, iron, biologicals, copper, manganese, aluminum, nitrates, organics, chlorine, turbidity, etc. Your public water company has to have its water tested at a certified lab monthly, and if any of the parameters are out of whack, the EPA will hear about it faster than you can say "boo".

      Saying your county won't pay for your water to be analyzed is a little untrue/misleading. Ask your water comany to send you results of the tests they have done. On the other hand, if you get your water from a private well, then the onus of testing IS on you. And as your /. analytical chemist, I *highly* reccomend you get at least the lead, aluminum, and E coli numbers on your well water.

    Overweight & Diabetes in Germany Due to overweight, obesity and inactive lifestyles, the number of people with diabetes is set to double from five million to 10 million in Germany in the next 10 years, doctors warned at a meeting of the German Society for Internal Medicine in Wiesbaden this week. Most worrying is the number of young people who are developing type 2 diabetes because of obesity. Unlike type 1 diabetes - an autoimmune disease that usually develops in children or young adults - type 2 diabetes is linked to obesity and lifestyle, and has traditionally been seen in mainly middle-aged and older adults.

      Type 2 diabetes is becoming a great concern in the U.S. as well, especially in children - an abundance of very fatty foods and a decrease in physical activity are among the causes.

      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 read something about this a few years ago.

        According to the author, while life expectancy has gone up in the last hunderd years, it isn't happending because people are living any longer than before. The rise is a result of dramatically reduced rates of infant mortality.

        Once the infant mortality rates are removed from the life expectancy formula, people are only living a few years longer than they did a hundred years ago.

          Are infant deaths factored into life expectancy calculations?

          http://mathworld.wolfram.com/LifeExpectancy.html

          Seems to me that at least the above method has a built-in correction. That they are actually measuring is the number of people (% of population) who die within age catagory x. If x is ages 30-40, then it has decreased in the past 100 years. If x is 70-80, then it has increased in the past 100 years.

          The conclusion is that more people are reaching the 70-80 age group, and therefore people pn average are living longer.

          At least that's my understanding...

        ... is that life expectancy has increased tremendously over the past hundred years,

        And, of course, this is one of the primary examples in intro statistics courses to explain why you need to know more than just such a sound-bite claim. It turns out that "life expectancy" is generally defined as the mean age at death, and almost all the change has been in eliminating causes of death before age 5. Life expectancy at ages 20 and up haven't changed all that much, despite all the medical advances. There has been a small improvement in advanced countries, mostly due to the elimination of some infectious diseases. OTOH, in some parts of the world, life expectancy past childhood has decreased in the past few decades.

        My wife, whose specialy in grad school was medical economics & statistics, likes to invite people to take a stroll through graveyards around here (New England) and note the ages at death. She actually did this for a class, and found that for people who lived past 50, the mean age of death was the same 100, 200 and 300 years ago as it is today. The difference is that there are now very few child graves.

        She also had a bit of fun in class by pointing out all the problems with her own "study", such as the question of what portion of the population was buried in graves that still exist. Such problems are rife in every such statistical claim.

          The National Center for Health Statistics doesn't quite agree with you.
          Life expectancy by age, race, and sex, 1900-2000 U.S. Life Tables, 2000, table 11 [cdc.gov]
          Summary: A person that reached 20 years of age between 1900-1902 could expect to live until they were 62.79 years of age. A person that reached 20 years of age in the year 2000 could expect to live until they were 77.8 years of age.

      • life expectancy has increased tremendously over the past hundred years, although medical advances probably greatly outweigh any negatives caused by pollutants

        Actually, the major part of the increase in average life expectancy predated most medical advances, and is almost certainly the result in improvements in public health (e.g. less shit in our water). I believe there's a bit of a blip when antibiotics came in, but that's about it.
      • "... an abundance of very fatty foods and a decrease in physical activity are among the causes."

        Perhaps you meant an abundance of easily-accessible complex carbohydrates and refined sugars that allow our children to get a sugar high from every meal of the day.

    Honestly, I am rather amazed at the human body's ability to seemingly tolerate the presence of these toxic chemicals for at least the short term.

    Unfortunately, it is rather difficult to say what will happen in the long term.

    With such chemicals like DDT, which continues to remain at high levels in the surrounding environment despite having been banned in 1970. I wrote a couple papers on the role of DDT in the decline of the Californian Condor, and it is really a scary chemical.

    Some scientists are even beginning to look at a link between DDT levels and breast cancer, as DDT and several other pesticides, which are absorbed and stored long-term in fat, also are capable of causing hormonal changes by acting much like estrogen. The unnatural changes caused by the continuing presence and buildup of DDT in mammary tissue could understandably be a large factor in the rising occurence of breast cancer. It could also have some particularly negative affect in men as well, as it acts as a blocker to the normal male hormones.

    • As I have come to understand it, chlorine gas (Cl2) in and of itself, is no more posionous than oxygen. The reason chlorine gas is useful as a weapon is because when inhaled it reacts with water to form a lot of acid

      Cl2 + H2O -> HCl (hydrochloric acid) + ClOH (hypochlorite acid)

      since there isn't a lot of water in your lungs (it can only react with the water on the surface of your bronchial tubes), the concentration is high and therefore leads to the acid eating away your lungs from the inside out.

    As somebody who claims to have followed the link, I feel decidedly nonplussed.

    Don't you hate it when people writing articles make up their own units? Whoever heard of measuring pollution in "humans"? This is pure bunk. Most useful units are standardized and published by ISO [www.iso.ch], and "humans" sure aren't listed anywhere I can see. And anyway, what's the symbol going to be, "hm"?

    Standardized units are essential when doing studies which claim repeatability. Anything less is simply not science. I shudder to think what useless arguments this will produce, when a swedish team checks their pollution readings in scandinavian humans, while an italian teams does the same in latin humans. At sufficiently high readings, the difference could be several percent! Then there are issues of hair colour and hair style, which could even change the results of the experiment years after the fact! And don't get me started on the problems every time bell bottoms get back into fashion.

    If you ask me, shoddy science begins with the wrong units. And humans are definitely the wrong unit to use in this case.

    "Everything is in everything else".

    The sensitivity of today's measurement techniques is stunning. But even decades ago, it was common knowledge among chemists that if you started looking at trace contaminants the results were like cleaning out your garage -- "what's THAT doing there?!".

    What's interesting is whether the odds and ends are in significant quantities. When you define "significant", remember that your body is a huge detoxification machine designed to survive consuming carrion, plants full of natural insecticides, and even unchlorinated water.
  • Blood and urine tests are often not reliable indicators of total body burden of a substance. Blood or urine levels can be low while significant (possibly toxic) amounts may be stored in various organs and visa versa.

    Also, due to health and genes, different people can tolerate vastly different amounts of a toxic substance before showing symptoms or being disadvantaged.

    Just from basic physics and chemistry, we know that if a chemical is anywhere around, it will be present in the environment and the human body at some concentration, so all this means is that modern analytical techniques have finally developed enough sensitivity to demonstrate what everybody with any sense knew already. The hard part is figuring out what the biological consequences of these tiny concentrations are--in most cases, the answer is likely to be somewhere between negligible and none.

    But it's OK, says the skeptical environmentalists: after all, we do not have definitive proof that all those substances are bad for you.

    Never mind that cancer is on the rise (could just be demographics, right?) and that dozens of species other than humans show hormonal abnormalities correlated with the presence of manufacured chemicals (could just be parasitic infections). Why be prudent and conservative if we can increase the GNP by 0.1%?

    In fact, it's probably impossible to prove at all that they are bad for you because no single substance may harm you--they may only harm you synergistically. And since you are exposed to all of them constantly, it is impossible to assign responsibility to individual chemicals. But without definitive proof that an individual chemical is harmful by itself, we wouldn't want to limit the freedom of corporations to pollute, would we?

    My brother has autism. Once we found out about it, we started researching and there has been a huge increase in children born with autism in recent years. Wired magazine even published an article trying to suggest that autism was on the rise in California relating autism to being smart. All hubris asside, there is something happening and we need to find out what it is.

    One theory suggests that Thirmosal used in childhood inoculations may trigger autism in some children because it contains Mercury which is a known toxin being injected into most children. There is even a provision in the Homeland Security bill which prevents companies such as Eli Lilly from being sued by parents if thirmosal is found to be the cause of autism.

    Even if it is not mercury in innoculations, autism is on the rise and for those of us with kids or planning on having them, this is a scary thing. I watched my brother revert from a normal 3 year old to ... well himself now, but trapped by autism. Hard to explain, but scary as hell now that I'm having kids of my own.

    The study mentioned in the article only included 9 people. Obviously not statistically relavant, but the findings found enough chemicals in the body that more studies analysis must be done to determine the effects on the body, and especially the developing young ones.
