Once again, you display either willful ignorance, insipid stubborness, blatant dishonesty or a true inability to comprehend what has previously transpired.
Once again, the chronology of the posts states my point. Once again, your refusal to actually READ the reference material linked and discuss information that supports my assertions and statements speaks volumes of your mindset in the forementioned categories.
Once again, I grow tired of arguing with an ingorant man who is proud of his ignorance.
Radiation is all around us Libbie. There is an ambient concentration. And people get exposed to it at the dentist, from radon in buildings, at the beach, or just walking to your car on a sunny day.
I used to manage sewage sludge for a major city in New York and headed up public discussions in all the surrounding towns where we had application projects. Folks would come in all hissy and screaming about "heavy metals". So I'd ask them to name these "poisons" and then write them down on a list. Then I'd put up a list of those same metals in ambient soils and stuff they bought off the shelf to put on their gardens, like fertilizer and lime. Then I'd take out a bottle of Centrum vitamins and pass that around, and showed that some of the same metals were in there, as nutritional supplements.
In a typical crowd of 40 or so I'd get nods of agreement from all of them except one or two and no matter what I said they'd made up their mind about the situation. I got cat-calls once in a while, shouts, an occasional threat, but I'll tell you a story about one guy that I'll never forget.
But first my point: there is always stupid assholes like you who, no matter what the science, have made up their closed minds before they entered the discussion.
Now for the story and I hope it shocks you as much as it did me (and everyone else in the room that night).
This was a rural farm community about 20 miles outside of the central urban area. I drove through this area many times each month and there was one farmer who used a complex system of plastic pipes and pumps to spread liquid cow manure. Once he spilled some on the road and I drove through it. My truck stunk for a week and I had to get under it with a hose and a scrub brush to get the odor off. I told you that story to give you an indication of what the town smelled like when this guy spread his manure pond, and what his neighbors had gotten used to.
Anyway the meeting took place in the town garage, because there wasn't enough room where the board usually met. They moved all the plow truck out except one that had a fuel pump problem and there was at least 40 people there. I start with my 15 minute talk and slide show and about half way through this guy waves his hand above his head and says "what about the heavy metals". So I addressed his question then completed my prepared talk and ask for questions and the same guy waves his hand again and says "what about the heavy metals". So I went into a little more detail and then answered a few more questions from folks in the crowd. After six or seven the guy waves his hand a third time and says "what about the heavy metals" so I turn the projector back on and show more data and more details. I then answer questions from the crowd until they peter out and then look over at the Town Supervisor and he nods then begins to stand up to adjourn the meeting and then the same guy waves his hand a fourth time and says "well I don't want that N----R SHIT around me anyhow.
Well I tell you jaws dropped and gasps were given all over the room. I just looked at the guy and didn't bat an eye. I've heard all excuses though had not heard that one- but was not surprised. My boss was speechless and could not close his mouth. Anyway the crowd left quickly and so did "Mr. Heavy Metals".
One the way back my boss and I discussed what had happened and he said that there were black folk who lived in the city and I guess this guy felt that he was getting their shit in his town. I never thought of that before, since I imagine black folks shit was the same as everyone else.
So for the corollary to my point: folks make up their mind about environmental issues as an excuse to conceal some other personal problem. For that guy it was racism. For others it was always more difficult to diagnose.
There was a tenured professor at Cornell who was on the heavy metal bandwagon and I could never figure out why. He published anti-sludge papers in local papers and farmers' journals- never scientific journals- and about three times per year one would come out and I'd have a rash of phone calls and meetings to deal with.
The one day Mr. Professor made the mistake of coming to one of my public presentations. After my dog-n-pony he raises his hand and asks a question about arsenic becoming concentrated over time like had happened in some orchards and I reached in my stack and put up a slide that proved, beyond any scientific doubt, that my product, over time, would actually
decrease the concentration of arsenic in the soils. I then explained to him that the product that he was referring to was a pesticide with arsenic as the active ingredient with a volatile carrier- not at all similar to my product which had arsenic concentrations approaching ambient and was mainly inert inorganics which act over time to dilute the ambient soil concentrations. He had no choice but to shut his mouth and had no further questions, because if he did I would have blown the rest of his theories out the window for all the world to see, at least the portion that was in that room.
Needless to say Mr. Professor continued to publish two or three times per year about the evils of sewage sludge and of course never in peer reviewed scientific journals. My guess is he got off trying to be an expert and maybe got kickbacks from commercial fertilizer manufacturers.
You, Libbie, will continue to spout nonsense about something you know nothing about, desperately clinging to the coattails of folks like Mr. Cornell Professor. You'll continue to call folks who know better mindless neocons, corporatists and all the other bullshit terms that you hear, when it fact it is you who are closed-minded and ignorant of the science.
You are SO full of it it's amazing......this little tale you spin is A-typical of the fog machine used by low level bureaucrats to excuse actions of others.
