Re: A bit of history, for those new to the anti-dioxin move
I'm gratified that you would quote me regarding the introduction of
plastics into industrial chemicals and products.
There is a great deal of anecdotal evidence that something really
quite odd is going on with respect to asthma, diesel exhaust, incinerators,
and dioxin (or maybe other organochlorine by-product, but dioxin is the most
potent of them...). The dioxin air emissions from incinerators are primarily
carried clinging to microscopic and sub-microscopic particulates. Diesel
exhaust is also known to contain dioxin, and the pattern of dispersion is
likely to be the same. As you know, the incidence of asthma in cities in
general and incinerator cities specifically has skyrocketed, to the point
where 1/3 of the kids have asthma and many adults are developing it as well.
There are many possible scenarios, for instance:
1. Dioxin interferes with the immune system. That much is known. The immune
system also has something to do with the Ah receptor, but the research is
sketchy. General immune system depression (to common colds and flu) is a
common symptom of dioxin exposure. It is also a common affliction of
"modern" allergy/asthma sufferers. Maybe there is a connection or
Whatever it is, breathing sub-microscopic particulates with dioxin molecules
clinging to them cannot be good for one's lungs.
2. Dioxin causes dysplasia - the growth of a type of cells that don't belong
in the place where they are growing. (An example is endometriosis, for which
dioxin is a known cause and, I believe, the only known cause). I have heard
of stomach acid cells growing on the lining of the esophagus.
At least one researcher has found a correlation between stomach acid
irritation and asthma. Another possible avenue of research.
In the city, asbestos is also a factor. Its irritative potential is
magnified by orders of magnitude when there are also aromatic hydrocarbons.
I hope this helps...
