 Europa - Public Health - Risk Assessment - Scientific committees - Toxicity, Ecotoxicity and the Environment - Opinion
The reported degree of risk from the use of the plasticisers o-acetyltributyl citrate (ATBC) and diethylhexyl adipate (DEHA) in PVC childcare articles and toys is not sufficiently justified, since it is not possible to perform an adequate exposure assessment on these substances.
The text presented on ATBC and DEHA on exposure and toxicological effects is almost exclusively an abridged duplication of the CSTEE opinion (of 28 September 1999) on those substances.
It is not possible to estimate DEHA intake doses for children from PVC toys, maximum emission rates from the toys and an intake dose.

 Meditation on Siddha Deha   (Site not responding. Last check: 2007-10-13)
Both of these acaryas have emphasized that one's siddha deha is experienced at the stage of asakti, at which time deep meditation on one's siddha deha is possible.
For the followers of Bhaktivinoda Thakura, perhaps the conclusion to be drawn from all of this is that meditation on one's siddha deha is appropriate at whatever stage and to whatever extent it manifests.
By all means, whenever one's siddha deha begins to manifest, to that extent one should try to meditate on it.

 Boiler Water Oxygen Scavengers; Sulphite Tannin DEHA Carbohydrazide
An example of an inorganic oxygen scavenger is sulphite, whereas examples of organic oxygen scavengers are tannin, DEHA, and carbohydrazide.
One method used to reduce the amount of oxygen in boiler feed water is to maintain as high a temperature as possible.
Tannins, DEHA and carbohydrazide are not temperature dependent and do not add to the 'dissolved solids' and hence blowdown is reduced relative to a sulphite treated boiler, however, these products are slightly more expensive than sulphite.

 Did Claire Nelson Find Cancer & Plastic-Wrap Link?
New plastics and plastic additives, such as DEHA, are permitted for food use only after FDA reviews the scientific data and is satisfied that they are safe for their intended use.
Also contrary to the e-mail, DEHA is neither regulated nor classified as a human carcinogen by the U.S. Occupational Safety and Health Administration, the National Toxicology Program or the International Agency for Research on Cancer, the leading authorities on carcinogenic substances.
Although a real student named Claire Nelson did receive an award for a school project in the late 1990s, the award was based on her systematic approach to exploring a question, not for identifying a danger to human health as suggested in the e-mail hoax.

Diethyl hydroxylamine is indeed sometimes abbreviated as DEHA but it has nothing to do with plastic water bottles.
The student examined a variety of other plastic bottles and found DEHA in the water they contained, leading to the conclusion "migration of DEHA was not limited to polyester bottles alone and other bottles may also pose a health hazard." But a critical control experiment was never done.
Actually, there is. Because DEHA is a ubiquitous plasticizer used in the manufacture of items ranging from toys to shower curtains, it shows up in trace amounts everywhere.

DEHA, or DOA, is one of the organic contaminants commonly found at trace levels in standard drinking water.
