Editorial Policy Environmental Science & Technology reports on aspects of the environment and its control by scientific, engineering, and political means. Contributed materials may appear as feature articles, critical reviews, current research papers, research notes, and correspondence. Central to the evalu ation of all contributions is a commitment to provide the readers of ES&T with scientific information and critical judgments of the highest quality. For the convenience of authors, the specific nature of each type of contribution is outlined below. Feature articles. A manuscript submitted for publication as a feature article should present useful discussion and opinion on important research directions in environmental science, developing technology, environmental processes, and social, political, or economic aspects of environmental issues. Each manuscript undergoes review by qualified peers as well as by the editors for the purpose of balance and elimination of inappropriate bias. Review criteria include significance of the scientific issue or process described, quality and succinctness of the text, and identification of potential research needs. Strict requirements for docu mentation of results, completeness of data, and originality, such as those applicable to research manuscripts, are not included in the review criteria for feature articles. Critical reviews. Critical reviews are thoroughly docu mented, peer-reviewed assessments of selected areas of the environmental science research literature for the purpose of identifying critical research needs. Criteria for accept ability include current importance of the field under review, thoroughness of the literature coverage, clarity of text, and adequacy of research need identification.
Current research papers. The research pages of ES& Τ are devoted to the publication of critically reviewed papers concerned with the fields of water, air, and waste chemistry, and with other scientific and technical fields which are relevant to the understanding and management of the water, air, and land environments. Contributed research papers will, in general, describe complete and fully inter preted results of original research. All research articles emphasizing analytical methodology for air or water analysis must include substantial application to environmental samples. ES& Τ faces some overlap with other journals in this area, and articles that do not contain, in the editors' judgment, a significant emphasis on envi ronmental analysis will be returned to the authors for sub mission elsewhere. Manuscripts should be prepared with strict attention to brevity. The vast majority of articles are expected to be fewer than four published pages. Processing time will be shortened if the editors do not have to return manuscripts to be condensed. Notes and correspondence, as well as full-length papers, will be published in the research section. Notes are shorter research reports describing preliminary results of unusual significance or studies of small scope. Authors of Notes should be able to justify why it is not desirable to wait for a more complete report to be published as a full-length paper. Correspondence is a significant comment on work published in the research section of ES&T. Comments should be received within six months of date of publication of the original article. The authors of the original article ordinarily will be allowed to reply.
Send manuscripts to Environmental Science & Technology, 1155 16th St., N.W., Washington, D.C. 20036. Address feature manuscripts to Managing Editor; research manuscripts to Manager, Manuscript Reviewing Office; include a signed copyright transfer form, a copy of which appears on the inside back cover of this issue.
Current Research Author's Guide This manuscript preparation guide is published to aid au thors in writing, and editors and reviewers in expediting the review and publication of research manuscripts in Environ mental Science & Technology. For a detailed discussion with examples of the major aspects of manuscript preparation, please refer to "Handbook for Authors of Papers in American Chemical Society Publications" (1978). Title Use specific and informative titles. They should be as brief as possible, consistent with the need for defining the subject of the paper. If trade names are used, give generic names in parentheses. Key words in title assist in effective literature retrieval. Authorship List the first name, middle initial, and last name of each author. Omit professional and official titles. Give the complete mailing address where work was performed. If present address of author is different, include the new information in a foot note. In each paper with more than one author, the name of
the author to whom inquiries should be addressed carries an asterisk. The explanation appears on the Contents page. Abstracts An abstract which will appear at the beginning of each paper must accompany each manuscript. Authors' abstracts frequently are used directly for Chemical Abstracts. Use be tween 100 and 150 words to give purpose, methods or proce dures, significant new results, and conclusions. Write for lit erature searchers as well as journal readers. Text Consult a current issue for general style. Assume your readers to be capable professionals not necessarily expert in your particular field. Historical summaries are seldom war ranted. However, documentation and summary material should be sufficient to establish an adequate background. Divide the article into sections, each with an appropriate heading, but do not oversectionalize. The text should have only enough divisions to make organization effective and comprehensible without destroying the continuity of the text. Keep all information pertinent to a particular section within Environ. Sci. Technol., Vol. 18, No. 2, 1984

that section. Avoid repetition. Do not use footnotes; include the information in the text. Introduction. Discuss relationship of your work to previously published work, but do not repeat. If a recent article has summarized work on the subject, cite the summarizing article without repeating its individual citations. Experimental. Apparatus: List devices only if of specialized nature. Reagents: List and describe preparation of special reagents only. Procedure: Omit details of procedures which are common knowledge to those in the field. Brief highlights of published procedures may be included, but details must be left to literature cited. Describe pertinent and critical factors involved in reactions so the method can be reproduced, but avoid excessive description. Results and discussion: Be complete but concise. Avoid nonpertinent comparisons or contrasts. Manuscript requirements Three complete legible copies of the manuscript are required. They should be typed double- or triple-spaced on 22 X 28 cm paper, with text, tables, and illustrations of a size that can be mailed to reviewers under one cover. Duplicated copies will be accepted only if very clear. If pertinent references are unpublished, furnish copies of the work or sufficient information to enable reviewers to evaluate the manuscript. In general, graphs are preferable to tables if precise data are not required. When tables are submitted, however, they should be furnished with appropriate titles and should be numbered consecutively in Roman numeral style in order of reference in the text. Double space with wide margins, and prepare tables in a consistent form, each on a separate 22 X 28 cm sheet. Submit original drawings (or sharp glossy prints) of graphs, charts, and diagrams prepared on high-quality inking paper. All lines, lettering, and numbering should be sharp and unbroken. If coordinate paper is used, use blue cross-hatch lines since no other color will "screen out." Typed lettering does not reproduce well: use black India ink and a lettering set for all letters, numbers, and symbols. On 20 X 25 cm copy, lettering should be at least 0.32 cm high—for example, with a Leroy lettering set, use template 120C and pen No. 0. Lettering on copy of other sizes should be in proportion. Label ordinates and abscissas of graphs along the axes and outside the graph proper. Do not use pressed wax for numbering or lettering; it rubs off in all the mailings and handlings necessary before receipt by printer. Photographs should be supplied in glossy print form, as large as possible, but preferably within the frame of 20 X 25 cm. Sharp contrasts are essential. Number all illustrations consecutively using Arabic numerals in the order of reference in the text. Include a typed list of captions and legends for all illustrations on a separate sheet. If drawings are mailed under separate cover, identify by name of author and title of manuscript. Advise editor if drawings or photographs should be returned to the author. Nomenclature The nomenclature should correspond, as closely as possible, to that used by other ACS primary publications (refer to "Handbook for Authors"). Use consistent units of measure (preferably SI). If nomenclature is specialized, include a "Nomenclature" section at the end of the paper, giving definitions and dimensions for all terms. Write out names of Greek letters and special symbols in margin of manuscript at point of first use. If subscripts and superscripts are necessary, place them accurately. Avoid trivial names. Trade names should be defined at point of first use (registered trade names should begin with a capital letter). Identify typed letters and numbers which 70A

could be misinterpreted, for example, one and the letter "I," zero and the letter "O." Formulas and equations Chemical formulas should correspond to the style of ACS publications. Chemical equations should be balanced and numbered consecutively along with mathematical equations. The mathematical portions of the paper should be as brief as possible, particularly where standard derivations and techniques are commonly available in standard works. Safety Authors are requested to call special attention—both in their manuscripts and in their correspondence with the editors—to safety considerations such as explosive tendencies, precautionary handling procedures, and toxicity. Acknowledgment Include essential credits in an "Acknowledgment" section at the end of the text, but hold to an absolute minimum. Give meeting presentation data or other information regarding the work reported (for example, financial support) in a note following Literature Cited. References Literature references should be numbered and listed in order of reference in text. They should be listed by author, patentee, or equivalent. In the text, just the number should be used, or the name should be followed by the number. "Anonymous" is not acceptable for authorship. If the author is unknown, list the reference by company, agency, or journal source. Do not list references as "in press" unless they have been formally accepted for publication. Give complete information, using abbreviations for titles of periodicals as in the Chemical Abstracts Service Source Index, 1975. For periodical references to be considered complete, they must contain authors' surnames with initials, journal source, year of issue, volume number, issue number (if any), and the first and last page numbers of the article. Consult the "Handbook for Authors" for reference style. Supplementary material Extensive tables, graphs, spectra, calculations, or other material auxiliary to the printed article will be included in the microfilm edition of the journal. Identify supplementary material as to content, manuscript title, and authors. Three copies of the supplementary material, one in a form suitable for photoreproduction, should accompany the manuscript for consideration by the editor and reviewers. The material should be typed on white paper with black typewriter ribbon. Computer printouts are acceptable if they are clearly legible. If individual characters for any of the material, computer or otherwise, are broken or disconnected, the material is definitely unacceptable. Figures and illustrative material should preferably be original India ink drawings or matte prints of originals. Optimum size is 22 X 28 cm. Minimum acceptable character size is 1.5 mm. The caption for each figure should appear on the same piece of copy with the figure. Be sure to refer to supplementary material in text where appropriate. Supplementary material may be obtained in photocopy or microfiche form at nominal cost. Material of more than 20 pages is available in microfiche only. Photocopy or microfiche must be stated clearly in the order. Prepayment is required. See instructions at the end of individual papers. The supplementary material is abstracted and indexed by Chemical Abstracts Service. Subscribers to microfilm editions receive, free, the supplementary material in microfiche form from individual papers in any particular issue.
