That is all I have found too but if you heat your dehydrator too high

then you might create outgassing of some of the chemicals I suppose.

That could create a problem. Course we don't really know at what temp

that would occur at. Hmmm.....Maybe it is time to make a wooden

dehydrator and move all the electronics to it and toss the #7.

Here’s a dehydrator that has chrome shelves – a

tad on the expensive side!

Okay, I really think the jury is out to lunch on this one. Here is an

article to read that may shed some light on this subject. However, we

all need to make our own choices. Plastics are not natural and we all

know that petroleum products are toxic. As are most chemically

synthesized substances that get churned out of the chemical houses. Read

and see what else you can find on it. It is interesting to note,

Excalibur was originally made from wood, as I recall. They then changed

to polycarbonate. Why I don't know. To save a tree or save money or what.

*New studies raise question of plastic water bottle safety *

If your Lexan water bottle does not give off an odor or taste, is it

safe to use? That’s the question raised by several recent studies

that looked at the risk from bisphenol A (BPA), a component of

polycarbonate plastics such as Lexan water bottles.

Review panels from Harvard, the European Union, and the U.S.

Environmental Protection Agency (EPA) looked at the studies. They

found no significant risk of BPA migration nor did they find

sufficient evidence of negative human health effects at low levels

of BPA.

There are caveats, however. The Harvard and EPA panels agree that

more research is needed because of conflicting conclusions reached

by the reviewed studies. Some studies also suggest that

polycarbonate does degrade under high temperature and with harsh

cleansers.

Until researchers have sorted out these results, you can play it

safe by hand washing polycarbonate bottles with a mild detergent to

minimize the risk of BPA leaching. Cleaning at high temperatures

with harsh detergents (such as in a dishwasher) or with bleach may

accelerate polycarbonate deterioration. In any case, remember that

plastics, while durable, do not last forever. If your water bottle

is cloudy and scratched, it is probably time to get a new one.

BPA is used in the manufacturing of plastics for food and beverage

can linings, PVC pipe, polycarbonate baby bottles, and the

ubiquitous Lexan NALGENE ® bottle (identified by a “7” on the

bottom). The use of these plastics retards metal corrosion and food

spoilage in cans, corrosion in water pipes, and creates strong,

lightweight beverage containers.

It has been known that BPA can leach out of some grades of

polycarbonate under high temperatures or alkaline conditions. What

remains to be determined is whether BPA can migrate at room

temperature or neutral pH from food-grade polycarbonate. If this is

the case, we must also find out how much BPA migrates under these

everyday conditions and what effects, if any, these levels would

have on humans and the environment.

BPA is suspected of being a hormonally active agent that mimics

estrogen. Elevated estrogen levels in males can lead to decreased

reproductive organ weight or function, or in a population they can

lead to more females than males being born.

The study most often cited as cause for alarm was published in the

journal /Current Biology /, April 2003. It found that BPA migrated

from damaged polycarbonate mouse cages and caused reproductive

abnormalities in mice.

A study in the journal /Environmental Health Perspectives /, July

2003, had similar findings. Polycarbonate mouse cages released BPA

at room temperature and neutral pH. The study also found relatively

higher BPA levels when the cages were old and worn, and detected

increased, but not statistically significant, reproductive

abnormalities in mice when they were exposed to these levels. The

BPA levels in this study were orders of magnitude lower than the

amount considered harmful to humans as set by the EPA.

Extrapolating from these studies to human health and the safety of

food-grade polycarbonate is a different story. Slight differences in

study design, weighing technique, or the specific grade of

polycarbonate used can affect the conclusion.

The Harvard Center for Risk Analysis reviewed 19 contemporary

studies of BPA leaching and its effects on laboratory animals. Some

studies did find a link between BPA exposure and negative health

effects such as reduced reproductive organ weight in laboratory

animals, but many others did not. The reviewers found the studies

had too many sources of potential error or their statistical

findings were not strong enough. The statistical power of the

studies that found no association between low levels of BPA and

health effects was actually stronger than those that did find an

effect. They also cast doubt on BPA even being an estrogen-mimicking

compound, as it does not have several key estrogenic characteristics.

The European Union Scientific Committee reviewed BPA studies using

food-grade polycarbonate articles and found no evidence of

significant BPA contamination under normal use.

Those of use who tote our polycarbonate water bottles from home to

work to class to hikes in the mountains, the jury is still out but

we can probably rest easy. In the meantime, we might want to wash

our bottles by hand.
