  •  as for autism.... (5+ / 0-)

    I would like to see some serious studies done about the rising rates of autism compared/correlated to the rates of cell phone use in the mother during pregnancy.
    As for fluoride being on that list (above) -- I think I'll read the study from Lancet.
    Thanks for your post.

      away from the baby. I could see looking for some maternal brain changes.

      I'd wonder if electrical radiation from laptops rested on the stomach or lap would have more effect on babies.

      but I do think the confluence of chemicals and perhaps their interaction with each other seems to explain some of problems we see.  Most importantly, we need to think carefully before blaming victims--often the poor and those lacking of power.

    •  Autism was around long before cell phones. (5+ / 0-)

      In fact, it's far from clear if autism rates are actually going up all that much since it wasn't diagnosed until fairly recently.

      •  That's the $100,000 question (0+ / 0-)

        We don't know the incidence of "that boy ain't right" back in the day, so we lack pre-contemporary baselines worth a darn.

    •  I agree....what has changed in our society? (0+ / 0-)

      It's the overall radio frequency field we're living in.  I don't even  know that it has to be proximity to a device.

    •  The Fluoride ion is ID'd based on a meta-analysis (1+ / 0-)
      Recommended by:
      Rich in PA

      of 27 studies - all focused on China. That is clear in the current Lancet paper very tersely summarized at the link you give, the original Lancet paper is found here: (PDF)

      A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations.
      Confounding from other substances seemed unlikely in
      most of these studies. Further characterisation of the
      dose–response association would be desirable
      As for the meta-analysis itself. They were looking at high fluoride ion concentration vs. low fluoride ion concentration in various regions of China. I infer that many of the studies in China subjected to meta-analysis concern naturally high fluoride ion concentrations. The studies examined sought to estimate IQ deficiency in response to higher fluoride levels. Some studies therein appear ripe for conflation between other pollutants and fluoride ion (high fluoride release in high coal burning areas).

      Here is that meta-analysis (PDF) which appears to be the sole basis for fluoride's inclusion in the list of newly identified neurotoxicological chemicals.

      One last thought - the fluoride levels at issue in the 27 studies subject to meta-analysis are often very high indeed. This reminds me that, when opponents of fluoride in drinking water say no to adding the ion to waters naturally free of the chemical, they also (unknowingly)  advocate for leaving water supplies bearing high levels of fluoride untreated to bring the fluoride ion level down to optimal levels of about 1-ppm (optimal for prevention of dental caries).

      •  That's the thing about fluoride. (0+ / 0-)

        We know that VERY high levels (of the sort that freakishly but "naturally" occur) aren't good for you.  The more relevant question is whether the standard human-inserted level is good for you and so far I haven't seen anything to suggest that.

    •  a lot of good comments, thanks. (0+ / 0-)

      I'd forgotten that I wrote anything which is why I did not respond to all the comments.

      ....When the phone is being answered, yes, quite distant from the baby, but we carry phones in purse & pockets, and we don't turn them off.

      to Rich in Pa -->

      I agree....what has changed in our society? It's the overall radio frequency field we're living in.  I don't even  know that it has to be proximity to a device.
      Yes, the overall increase in the radio frequency fields in our society .... it must have gone up immensely now that we all have cell phones and wireless stuff.

      to Publius 2008 -->

      Yes, drug/chemical interactions are not quantifiable at all. Too many, too much.

      Autism has been around forever, but yes, different definitions... remember it used to be blamed on poor maternal attachment (during the baby boom generation).
      But rates have risen dramatically even by loose definition standards.
