Every few days in Silicon Valley, CA we are treated to a kind of stench
in the air probably caused by arsenide gas from our various wafer fabs.
It ranges in concentration from 'merely distracting' all the way to the
kind of in-your-face pall reminiscent of the worst days of the '70's.
(Think 'Chewable Air')

Just now I discovered that wearing my painting respirator with type 6003
Organic Vapor/Acid Gas Cartridges almost completely removes the smell.

Just a heads-up for folks also benefiting from our high-tech
environment.
