Frogs with > 4 legs are actually quite common, even in areas where the
chances of pollution are zip. I recall an article from the New York
State Conservationist, perhaps 10 years back, showing a frog with a few
extra appendages. Amphibians are genetically fairly mutable; there are
some frogs that are completely parthenogenetic (requiring no males for
reproduction).

Karen Silkwood's problems were with Plutonium, which is indeed deadly in
small amounts (esp. 238Pu). Depleted Uranium is rather innocuous; it has
a far greater kidney toxicity than alpha toxicity. I recall reading that
you could feed rats about 2% soluble 238U/day for 30 days (2% of total
diet) before seeing the kidney failure. Kerr-M was not angelic in the
days of Karen Silkwood; her protests were justified. But she was also a
bizarre person, with a phenomenal drug habit and a prior conviction for
driving off the road.

There is no documented case of human mutagenesis from radiation
(teratogenesis, yes; mutagenesis, no). Even at Hiroshima, where the
doses were phenomenal. For a while, there was an indication of
microcephaly, but it turned out that the incidence in the bomb areas was
indistinguishable from background.

I'm not sure how to deal with postings like the one referenced above.
There are some hooks to real science in this paranoid rambling, but
whenever quantitative reasoning is required, the eco-fascists tend to
focus on emotions rather than numbers. As Adolf Hitler showed, if you
can pray on peoples' fears, you have a very powerful constituency.

Subject: Testing for LEAD in Paint
Organization: AT&T
Distribution: bl
Date: Tue, 13 Oct 1992 17:41:18 GMT
Keywords: Paint lead



Hello to all those wanting to get the lead out.

My wife (a M.S. chemist, M.D. epidemiologist with the Centers for Disease
Control) works in the environmental hazards division of the CDC.  The
CDC has a Lead Branch and I asked her the question about testing for lead
in the paint, versus sending it to a lab.  She sent e-mail to her 
associates in the lead branch and got back these replies.  

Hope this helps with the lead discussion.  By the way, and of course it
is of academic interest, I don't really care if it is PbO2 or Pb3O4.
It is still lead and it is still a danger to children and adults.

---------------------------start of replies----------------------
The test kits are available, but their sensitivity and specificity are 
variable.  It is probably ok to use a swab as a gross screen for very high 
lead levels in paint, as long as you get paint chips or cut through your wall 
to the bottom layers.  However, you cannot say how much lead is in your paint 
as a result of a swab test. Consumer Reports reported on test kits last year. 
------------------------------------------------------------------------------
The easiest way is to do an XRF reading.  If lead paint content is very high, 
the reading is fairly reliable.  Around the border zone between what is 
considered lead-painted and is not, the XRF is not as good.  The most 
accurate test is to have a laboratory analyze paint chips (that contain 
all layers of paint) for lead content.  However, one has to get chips from 
all questionable surfaces, and obtaining these chips is destructive to the 
wall.  How I would evaluate the environment would depend on exactly what the 
situation was.  In some cases, for example, I would test dust lead levels and 
not paint.  If you want to tell me about the specific situation, I may be 
able to help you.  The agency responsible for testing varies from state to 
state.  In many places and situations, it has to be done by contracters who 
are paid by the homeowner.  Let me know the issues and I'll be glad to give 
you more specific information.

-----------------end of replies----------------------
My note:  XRF is x-ray fluorescence.  There is a hand-held device that you
can place next to the paint and read the x-ray fluorescence.  Some local
health departments have these and will come out and check for your paint.
However, this depends on your locality and your health department.  They are
not required to have or do this test.  Call your local health department,
inquire about the test, if they don't have/do it then demand that they get
the equipment to do it.  If enough people call, then they will do it.

I've never heard of PbO2 used in paint; the highest Pb oxide likely to

Note I said 0.2 atm O2, not "room pressure". The electrochemical
(Pourbaix) diagram for Pb shows PbO2 up in the region above the
dissociation of water... conditions you can reach in a battery or in
some bleaches, but not in normal atmospheres (if PbO2 forms in a car
battery, you can bet the effective O2 pressure is well above 0.2 atm).

In normal air, PbO2 is probably metastable. So is diamond, but I'd wager
that PbO2 is a lot more reactive "in our lifetimes".

But the HFCs are bad greenhouse gases. Look at the IR spectra of these
molecules, and you will see. CF4 should be perfectly safe, but it is a
potent greenhouse gas. Just like the C2F6 gas from Al production.
So none of these molecules are friendly ! They are usefull and nice to use
but all of them have side effects !

	Came across the following in the local newspaper and would like to
share with fellow chemists:

South China Morning Post, July, 1992.

**Treat with care**

	When industrial planners are choosing raw materials for projects,
they study a document called the Hazardous Materials Data Sheet.
	Mike Yalden of Richardson Pacific sent us the latest such sheet,
since it concerns a hazardous item many of us come across in everyday life.

	ELEMENT: 	Woman
	SYMBOL:		WO^2
	ATOMIC MASS:	Accepted as 118 lb but know to vary from 100-500 lbs.
	FOUND:		Copious quantities in all areas
	PHYSICAL PROPERTIES:
	(1)	Melts if given special treatment
	(2)	Bitter if incorrectly treated
	CHEMICAL PROPERTIES:
	(1)	Has great affinity for gold, silver, platinum and precious
stones 
	(2)	May explode spontaneously without prior warning and for no
known reason
	(3)	Activity greatly increased after alcohol saturation
	(4)	Most powerful money-reducing agent known to man
	COMMON USES:	
	Highly ornamental, especially in a sports car.
	TESTS:
	(1)	Pure specimen turns rosy pink when discovered in natural
state
	(2)	Turns green when placed beside a better specimen
	HAZARDS:
	(1)	Highly dangerous except in experienced hands,
	(2)	Illegal to possess more than one.


South China Morning Post, July 23, 1992.

**Base element**

	Several speciments of WO^2 offered a follwo-up to our hazardous
materials guide, offering one for men:

	ELEMENT: 	Man
	SYMBOL:		EG^0
	ATOMIC MASS:	MOST think they are 150lbs but actually vary from 
98 lbs to 650 lbs
	FOUND:		In large quantities around alcohol outlets
	PHYSICAL PROPERTIES:
	(1)	Made of much denser materials than WO^2, especially between
the ears
	(2)	Black lump in centre-left chest is the hardest material
yet discovered
	CHEMICAL PROPERTIES:
	(1)	Turns a bright shade of crimson when asked to describe 
feelings
	(2)	Froths violently when placed in view of sports events
	COMMON USES:
	(1)	Useful for unskilled labour, such as changing light buls
	(2)	Used as bed warmer by WO^2
	TESTS:
	(1)	Becomes completely inert when faced with domestic chores
	(2)	Dissolves into tears (H_2O) when their team loses.
	(3)	When plaved near WO^2 in a bikini, middle portion of EG^0
is sucked in and upper portion thrust out.
	HARZARDS:
	(1)	Stupid
	(2)	Doesn't know it.

Subject: Spin density calculations for benzene
Organization: University of Jyvaskyla, Finland
Date: Sun, 11 Oct 1992 13:02:24 GMT


We just received gaussian 92 and I tried to calculate spin densities for
benzene anion. The results were (using HF):

 Total atomic spin densities:
              1
  1  C   -0.434526
  2  C    0.493475
  3  C    0.494552
  4  C   -0.434527
  5  C    0.493482
  6  C    0.494592
  7  H   -0.040585
  8  H    0.027736
  9  H   -0.040687
 10  H   -0.040576
 11  H    0.027740
 12  H   -0.040677
 Sum of Mulliken spin densities=   1.00000

This result is not symmetrical (obviously it should be..). Does anyone know
why? The only reason that I can think of is that benzene has orbitals nearly
with the same energy and the electron is jumping from one level to another.
This would mean that I had to take mean value of the spin densities for
these orbitals. If I do this then I get nearly the correct value
(= measured value with EPR spectrometer). If this is true then this would mean
lots of troubles for more compilcated molecules... :-(

Gaussian also reports the following values:

 Fermi contact analysis (atomic units).
              1
  1  C   -0.158284
  2  C    0.134964
  3  C    0.135348
  4  C   -0.158284
  5  C    0.134970
  6  C    0.135350
  7  H   -0.020671
  8  H    0.013269
  9  H   -0.020724
 10  H   -0.020667
 11  H    0.013271
 12  H   -0.020718

How are these calculated are what are they? From "Fermi contact analysis"
I could think that it is hyperfine coupling constant calculated using
Fermi's equation (ie. constant * psi(at nucleus)**2)?
