I would be grateful to you
for further information on:

Congressional hearings of the last few years
on ‘*AI POLLUTION; particularly auto exhausts .
*lestimony relating to enactment and implementation
of the Air Quality Control Act 1967.

Did you see my piece on Nickel in Saturday's bashéngton Post?

How serious this is really depends very much on the chemical form of
the nickel emitted. The people at Sinclair Oil Co. are themselves
concerned about this, but it @s odd that the product should be widely
distributed before the appropriate biological and chemical research

is done. Nickel may already be a serious pollutant in New York City
and other urban centers; once again we don't know enough about the
chemical form of it to bé sure of the consequences. A lot of it may
come from burning coal. It also comes from spark plugs, the ignition
points being rich in nickel, and gradually eroding away.

Thank you
