PUBLICATIONS--"A Primer on Sediment-Trace Element Chemistry" (Second Edition), In Reply Refer To: August 7, 1991 Mail Stop 412 OFFICE OF WATER QUALITY TECHNICAL MEMORANDUM 91.08 Subject: PUBLICATIONS--"A Primer on Sediment-Trace Element Chemistry" (Second Edition), by Arthur J. Horowitz Initially the Primer (first edition) was published in 1985 as U.S. Geological Survey Water-Supply Paper (WSP) 2277. Designed to be used in training courses on sediment-trace element chemistry, the first edition has been widely distributed. Inclusion of solid-phase chemistry in the Water Resources Division operational program has increased over the past 7 years. Additionally, research has continued and our understanding of sediment-trace element chemistry has increased since WSP 2277 was published. We are pleased that Art Horowitz has taken the time to incorporate the new insights and produce this second edition of the Primer. Copies of the subject publication have been provided to each Region and District. Individuals interested in obtaining a copy may contact Art directly in the Georgia District office (FTS 257-6860 or (404) 986-6860). David A.
