See Star, this is the power of the media
If an intelligent person such as you, who is technically savvy can be totally mislead , what chance does the average Joe have who did almost no science in high school ?
Had I not done the 5 years with Unitest I would have been just as ignorant as the next person
And had I not been in charge of the biological monitoring of the workforce I would have been as easy to brainwash as the next person
I used to monitor the workers for Pb,Zn,Cd, Sb & Cu poisoning so had to be conversant with the symptoms , sources & consequences.
Lead was misrepresented as being the reason why there were air quality problems and those air quality problems were then attributed to development problems in children .
While it was true because it COULD have happened in reality the actual source of the lead was mostly paint.
Since then all sorts of professional lie tellers have been graphing health against lead in petrol, ignoring all sorts of other things like the shift from solvent based enamel paints to acrylics
The shift from lead oxide to zinc oxide & titanium oxide as pigments
The shift away from chromium tanned leather.
Just about every building over 3 stories uses copper water pipes that are soldered together.
Most farms on tank water used galvanised steel tanks that were soldered & riveted together before plastic tanks became available and that water often came off galvanised iron roofing using lead flashing and collected in soldered guttering.
WWII caused an explosion in chemical analysis development, away from wet chemistry to spectrual chemistry through to things like atomic vibrational chemistry ( magnetic resonance ) .
So chemists suddenly had very fast , very accurate and unbelievably sensitive tools.
Then we started to find things we did not know were there because the new tools could find very low concentrations .
A prime example of this what the Cryptosporidium & Giardia fisco Sydney in the 90's
Prior to the installation of the new computerised analysis of Sydney's tap water we ran every drop through a fish tank with some Macquarrie Bass in them.
Now this fish is one of the most sensitive to water quality and if the fish suddenly looked crook they turned the valves off & did a chemical & biological analysis of the water.
The new system was way too sensitive and suddenly showed the actual amount of Crypto & Giardia that was in the water so the water department went into a panic & shut off the water
Health alerts were issued every hour for days , bottled water issued to all resturants & food processors , households told to boil all water etc etc etc.
Then some of the sacked ( because the new machine made them redundant ) chemists were re-employed and the first thing they did was to bring some bass down from Newcastle & put them in the water.
And wadda you know, the fish were quite happy.
So they brought water from every catchment & dam in and ran it through the machine which condemed them all as being unsafe yet none of the towns & cities that were drinking this water showed no increase in sickness.
However individual testing by real people all showed the water to be perfectly safe .
Now to the cruxt of this little diversion
Thousands of residents suddenly came down with food posioning and all the experts attributed this to Crypto & Giardia in the water because they now knew it was there.
And this is exactly what happened to lead , everything that could be attributed to lead posioning was deemed to be derived from the lead in the petrol despite the fact it is impossible for a body to process it after it comes out of the tailpipe .
