Please explain where the benzene and chloroform gets into my
showerhead and

what concentration in the house air might develop from this practice
and how

that relates to the safety standards.

The chloroform is in all municipal drinking water that has been
disinfected with chlorine to prevent water borne disease (such as
cholera). Chloroform is formed from the reaction of the chlorine
with natural compounds (humics) are present in almost all waters.
Chloroform is volatile, meaning that it comes out of the water into
the air when you use hot water in your home. So you and your kids
breathe this carcinogen.

Benzene comes from different sources in the home, not the shower
(please read the FAQ!): cars parked in attached garages, fuel storage
in the home, solvents, paints, even inks, woodstoves, and -- the big
one -- second hand smoke.

Studies of volatile carcinogenic pollutants in the air in urban homes
around the world including the US found levels that ranged into the
regulated levels for benzene and chloroform and for formaldehyde
(which our GMO does not degrade). for citations see the full proposal
on our website. So most homes were below the workspace regulatory
levels, but consider this: children and their adult caretakers spend
nearly all of their time in these environments with these low level
known carcinogens. These exposures are important.


There is a movement that says you can sell anything in the western
world if

you invoke the boogieman of danger to children.

Our children are precious

Exactly the same emotive motherhood and apple pie statement as any salesman
would make. I thought that you were a scientist.


This idea tells us to buy

special products to sterilise the inside of our toilet bowls and
every

surface in our house and to have a machine on the wall that pumps out

perfume/insecticide/ bactericide all day at timed intervals.



Now I would much prefer to house full of plants to splashing
chemicals

everywhere but I am doing neither until both the need and efficacy is

demonstrated. Your web site seems devoid of both.


Dear David, If you live with chlorinated water, when you shower you
fill your home air with chloroform.

I don't. But for those who do how much chloroform and how much is
dangerous? Your FAQ has no numbers.

If you store your snow-blower or
lawnmower or park your car in your garage you "splash" benzene into
the air that your family breathes. Please read our website,
especially the FAQ, to really understand these important issues and
how our new technology can provide some relief.

I read it and if you had read my questions you would know the FAQ doesn't
address them. Until you provide evidence that there is a significant risk
I won't be giving you money to develop a product to deal with it. So far
you are still in the same category as those who want to charge me money to
turn my toilet water blue.

If you have any information that that chloroform, or benzene reach toxic
levels in homes, you should share it.

11. === Toxicological Information ===

Toxicological Data:
Chloroform: oral rat LD50: 908 mg/kg; skin rabbit LD50: 20 gm/kg;
inhalation rat LC50: 47702 mg/m3/4H; irritation data: skin rabbit 10
mg/24H open mild; eye rabbit: 20 mg/24H moderate; investigated as a
tumorigen, mutagen, reproductive effector.
Reproductive Toxicity:
Birth defects have been seen in rats and mice exposed by inhalation of
chloroform at concentrations greater than 100 ppm in air. Ingestion of
chloroform by pregnant laboratory animals has resulted in fetotoxicity
but not birth defects, and only at levels causing severe maternal
effects.

From your presumed website:
http://faculty.washington.edu/sstrand/project5.html
[W]e have expressed mammalian cytochrome P450 2E1 (CYP2E1) in plants,
achieving orders of magnitude greater oxidation of trichloroethylene in
transgenic poplar. We are presently engaged in testing trichloroethylene
degradation by wild-type and CYP2E1 transgenic poplar at field scale in
a test bed facility capable of mass balance measurements. We are also
studying the pathways and genetics of volatile organic compounds
metabolism in plants, and to developing new applications for genetically
modified phytoremediation.

It seems that you are far from your goals, and have over stated your
case.
