INDEX TO NATIONAL AIR TOXICS INFORMATION CLEARINGHOUSE
     NEWSLETTER:   DECEMBER 1983 THROUGH MARCH 1989
-------
ABOUT THE NEWSLETTERS

     The National Air Toxics Information Clearinghouse Newsletter is
published by the Clearinghouse to inform interested persons of current
activities related to toxic air pollutants.  To be placed on the mailing
list, contact the Clearinghouse staff at (919) 541-0850 or (FTS) 629-0850.

HOW TO USE THIS INDEX

     Alphabetically arranged key word headings (in boldface type) are
followed by a subheading describing the context in which the key word
appears in the indexed Newsletter article.   The title of the article itself
is not given since, for example, an article on California's process of
identifying and controlling toxic air pollutants might discuss at length, or,
at the other end of the scale, briefly mention, a good many topics of
interest to Newsletter readers.  Both broad topics of discussion and brief
mentions of an item are indexed for the sake of completeness.
     The subentry is followed in turn by a locator consisting of the
Newsletter month and year plus page number on which the information may be
found.  Subsequent references to the key word in other Newsletters are
separated by semi-colons and have their own subentry phrases as necessary.
Thus, the entry, Acetaldehvde. tells the reader that he may find that
substance referred to in the context of California's air toxics
identification and control process on page 5 of the December 1984
Newsletter.  The second locator tells the reader that further information on
acetaldehyde in the same context (in this case, California revised the list
mentioned in the December 1984 article) may be found on page 6 of the
May 1985 issue.
