Guest guest Posted September 5, 2009 Report Share Posted September 5, 2009 Armour makes some good points, in agreement with my previous postings, about nano outside of direct use inside consumer products. My posting was very specific to consumer products that directly use nano particles and do *nothing* to contain them in the product. 's post provides good clarification. I elaborate on his points, reinforcing it, and revisit my point, and reinforce that as well. The topic is complex, and I give examples you likely are familiar with.

After this period is past, as the substance ages, it might begin a rapid release of the encapsulated nano particles. Might. Some products certainly well. And those will be dangerous. Some products will be dangerous even when brand new. There are no rules, regulations, laws, or agencies attempting to protect the public from such " abuses. " This situation has been going on since the use of petroleum products by industry back in the 1800's. And even before, with lead glasses used to drink wine in Rome. Before they knew lead particles made people stupid. Lead is used in medical radiation centers to protect key body parts from excessive xray exposure. So, lead is fear in some aspects, likely bodily contact to particles, but not bodily contact to sheets of it. Size is a factor. Molecular shape is the key here. When the shape is huge, it will have little impact on the body. When the shape is in the range of the body's molecular processes, inhaling, digestion, etc, there is not just a likelihood of dangerous interaction, there is a clear and present danger. Why? The body has never developed defenses through the millions of years of evolutionary development. Formaldehyde is an example that goes totally towards fearing it in any consumer product. Fluoride I would add to that. Even in medicine. Chlorine, related to fluoride, is much less dangerous than fluoride, yet poses threat to those not fully healthy, or too young or old. Look at teflon cookware, a chemical used in it's manufacture has never been in any consumer product, and yet industry has allowed every animal to have it their blood. Point is, there is a broad range of industrial chemicals, similar to 'nano tech', which has a broad range of impacts upon consumers. The unpredictability of 'nano' is a hazard. Even more so is the human unpredictability for ensure safe manufacturing. To talk further on these points would be off topic for this list, imo. To summarize, there are now two entirely separate topics dealing with nano. The first is nano " particles " in consumer products that are *dangerous*, brand new and as it ages. The other is nano " tech " used in making products, or as I put it, in " industry " by " experts " who know how to keep the employees safe, or safe enough (which given the Precautionary Principle would mean, it's not safe, imho, to employees, and/or to the consumer. " Nano Tech " in manufacturing is producing some wonderful products, which will be revolutionizing segments of both industry and consumer, mostly industry. Most of the applications I know are within industry, never to be seen by a consumer. Computers designed not with 55, or 50, 30 or 10 microns thick electrical " wires " or pathways, but bucky tunnels, just 4-5 atoms wide. Enough computer power in your wristwatch to match the entire total of all supercomputers in existence today. Sensor technology for mold, toxins, of unheard of concentrations, down below parts per billion, non clogging, ever lasting safety monitoring. DNA analysis of entire animals or plants within a few seconds by a hand held device. Delivery of medicine directly into an organ, or cancer cluster. Truly amazing future. You may say my examples are all things you want, but I maintain you will not see them as consumers. Computers that powerful are military weapons, and you will not have them. Sensors that keep you so safe, are not good for your immune system, and like accurate CO digital readouts with adequate alarm levels, will be prevented from entering the consumer marketplace. DNA analysis is so abused today, in understanding what valid conclusions can be made from it, that such devices will be available to only trained license holders. So, 's point, do not 'fear' nano should *not* be overgeneralized to include everything nano, I completely agree with. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 5, 2009 Report Share Posted September 5, 2009 , Brief comment on your response to . BTW, the two of you are having a good discussion. My comment has to do with the casual use of the word " fear. " Why, if we don't like something or are uncertain, are we afraid? Why not cautious and then check it out more closely? Some of my efforts in the past which I initially " feared " were actually a tremendous help to me. Some, like Vitamin C, made me very ill except for one specific brand. It was my lifeline while very ill. But I would have never found it if my fear kept me away from all Vitamin C. Let's not automatically assume the unknown is to be feared. Some discretion and research may be needed before a decision is made. Which this group is usually very good at, and is the reason it exists. Find out more before the hysteria. What helps me may harm others. And, conversely, what harms me may help others. That's the conundrum or our affliction.
