Measuring Pollution In Humans

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."

    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.

      ... 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.

      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.

    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.

    And that is just one of the chemicals commonly found in the body, as described in the article...

    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.

    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, 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.

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.
