DPRG mailing list archives: [DPRG] breathe

Mon Jul 29 18:32:01 CDT 2002

Actually for the past two weeks or so we have had Smog alerts constantly.
I would suspect that it is all that smog in the atmosphere settling out onto
the surfaces causing the oily effect. We've got tons of particulates in the
air, rubber dust from tires, diesel smoke from trucks, unburned hydrocarbons
by the ton. Unburned hydrocarbons condense out as a oily film on the car
windshields and such. I don't remember them spraying anywhere except south
of I30 though.

Ed:
You may be right. However, this particular combination of circumstances
hasn't happened before, and I've watered the car before. Also, the process
of managing my feedings involves the use of water in clear glass
containers. This gives me visual clues about the tap water eight times
a day and I haven't noticed any residue on the glasses after I finish.

Now that it has rained, if stuff was there before, it is gone now. Until
(unless) they spray near here again after a dry spell so I will water
again. So, I can't repeat the test; it is hard to test a hypothesis when
you don't have control of the lab!
