When I was a postdoc at Oregon State, someone told me that the summer haze
in the Willamette Valley was due to the emission of hydrocarbons by the
conifer forests (back in 1979 there wasn't much industrial pollution up
there, hopefully this is still true).  Whether this is due to terpenoids
primarilty I can't answer.

>I told him that I didn't know anything about it but would try to find out.
