[Pharmwaste] Nanomaterials in medicines, toothpaste, foods, sunscreens, etc.--and growing health risks

Wed Apr 7 13:47:02 EDT 2010

Google it, you'll find many studies, many more questions and a complete lack of any regulatory framework for the use of nano's.  The process will be similar to that for the random use of every chemical we could synthesize into every product we consume. Only years later do we find out many were carcinogenic, endocrine disruptors, etc.  First we question it, then we try to study it, then people question the studies, then we study some more, then we start seeing actual impacts, yup, we're going to go through the same thing with nano's.  HEY LOOK WHAT WE CAN DO!  Put silver particles in your socks so your feet don't stink!  Then later we discover we should perhaps have studied their use more PRIOR TO stuffing them into food, socks, washing machines, personal care products...

Many professionals familiar with Green Chemistry concepts and concerns about the lack of federal oversight or investigation into the use of chemicals are also very concerned about the un restricted use of nanoparticles.  Questions have been asked for years, meanwhile the ostrich digs deeper while those interested in quick profits from untested science grow rich and powerful.

jeepers, this stuff is getting to me today,
JV, my own personal opinion

Has this study been published in a peer reviewed journal?

Folks:
This series of articles should be read and we should all be aware of the risks of the FDA, EPA, and USDA acting like ostriches with their heads buried in the sand.  The current actions clearly shout:  "If we do not look for problems, we won't find them and have to respond in any way." (?sound familiar--like asbestos, etc.?)

Scientists now know that nanomaterials can damage or destroy DNA or chromosomes and have been linked to "the big killers of man" (like cancer, heart disease, strokes, endocrine disruption, etc.---to say nothing about what will happen in vitro to any fetus and the chance of live birth or a child with full physical and mental abilities!).

This is about the scariest series of articles I have ever read and it includes pharmaceuticals, disposal of drugs, and other waste streams as well as imported foods dipped in nanomaterials to increase shelf life of produce and its potential impact on human health.  The US is ignoring nanomaterials, but Canada and the EU are not.

Amid Nanotech's Dazzling Promise, Health Risks Grow March 24 2010

-- For almost two years, molecular biologist Bénédicte Trouiller doused the
drinking water of scores of lab mice with nano-titanium dioxide, the most common
nanomaterial used in consumer products today. She knew that earlier studies
conducted in test tubes and petri dishes had shown the same particle could cause
disease. But her tests at a lab at UCLA's School of Public Health were in vivo
-- conducted in living organisms -- and thus regarded by some scientists as more
relevant in assessing potential human harm. Halfway through, Trouiller became
alarmed: Consuming the nano-titanium dioxide was damaging or destroying the
animals' DNA and chromosomes. The biological havoc continued as she repeated the
studies again and again. It was a significant finding: The degrees of DNA damage
and genetic instability that the 32-year-old investigator documented can be
"linked to all the big killers of man, namely cancer, heart disease,
neurological disease and aging," says Professor Robert Schiestl, a genetic
toxicologist who ran the lab at UCLA's School of Public Health where Trouiller
did her research.
