Please take the time now to review this packet carefully, paying particular attention to the Guidelines for Symposium Organizers. It is important that you plan your program well in advance to allow yourself, and prospective authors, sufficient time to meet deadlines. As soon as you have a finalized version of the call for papers available, please forward it to me sot that I can get it posted to the web. ACS short abstracts must be submitted electronically to the OASYS website (see above) where you can review them as they are posted. ACS will no longer accept paper abstracts. Extended abstracts are to be sent to you by email attachment. Directions for their preparation are described on the program website (above). Once you have received all short and extended abstracts from authors, you are responsible for putting them in order and grouping them into half day sessions and submitting the abstracts and appropriate forms to us by our deadline, preferably by email attachments. You do not need to send all papers and forms at one time, however, please note clearly that it is your symposium to avoid confusion. Please keep me and the Program Chair informed of your progress, and if we can help, don't hesitate to call. Sign the symposium organizer agreement form and return it to me as soon as possible. Sincerely, Ruth Hathaway Business Office Manager Enclosures: (See following page) A8-1 Appendix 8 Enclosures: Symposium Organizer Agreement Form Guidelines for Symposium Organizers Call for Papers Example Organizer's Letter to Participants Example Instructions for Preparing Extended Abstracts Instructions for Poster Session Authors Cosponsor/Colist Request Recommended Session Format Session Format Example Meeting Time Table ACS Letterhead A8-2 Appendix 8 SYMPOSIUM ORGANIZER AGREEMENT FORM Extended abstracts are published in the Division of Environmental Chemistry's Preprints of Papers CD, in association with the program presented at each National meeting. The Program Chair of the Environmental Division reserves the right to refuse acceptance of any paper for which the ACS or extended abstract is not provided and may cancel any symposium that does not conform to these requirements. As a symposium organizer, I understand that it is my responsibility to obtain the ACS and extended abstracts from my speakers in the proper format prior to the published deadline for submission of abstracts to the Business Manager and Program Chair. I also understand that should books or other publications result from the symposium that it is usual and customary for the Division of Environmental Chemistry to share in the royalties. I agree to share any resulting royalties with the Division of Environmental Chemistry. The customary royalty split is 60:40 editor/author:the Division of Environmental Chemistry. I also agree to give ACS first right of refusal to publish any book that results from this symposium. Signed Date Washington, DC, August 28 - September 1, 2005 Global Environmental Regulation: Regulation of Chemicals - A View towards 2015 A8-3 Appendix 8 GUIDELINES FOR SYMPOSIUM ORGANIZERS Thank you for agreeing to plan and organize an ACS-sponsored symposium. You will find the task personally rewarding. The information presented may have long-term scientific value, particularly if it results in "open-literature" publications. In addition, your interaction with peer scientists, highly qualified in their fields, can be stimulating. These simple guidelines are to assist you in timely development of your symposium. Planning Time Select an appropriate ACS meeting for the proposed symposium in consultation with the Division Program Chair. Allow yourself sufficient time for adequate preparation. Major symposia may require up to two years to plan and develop, whereas minor symposia may require much less time. Planning time is highly variable. Symposium Length Decide whether the symposium topic or subject matter justifies a long symposium (2 to 4 days) or can be adequately covered in as little as one half-day session. This decision will affect your solicitation and publication plans. Coordinate with the Division Program Chair to be certain the time/space is available. Allow for papers that may be contributed after the symposium and topic is announced. Paper Solicitation Prepare a list of experts in the field. Develop a letter on appropriate letterhead (several sheets enclosed) stating that you invite the leaders in the field to contribute papers for presentation at the 2xxth National Meeting of the American Chemical Society to be held in City, State. State requirements for abstracts and preprints as indicated in the attachments and book manuscript requirements (if known) depending on your plans. Optional: Include an easy to fill out form for the potential speaker to return to you giving the speaker the option of making a firm or probable commitment; include space for addresses (email and mail) and phone numbers of authors. Symposium Publicity It is generally the responsibility of the symposium chairman to publicize the symposium by letter, call for papers, handouts at the Division table at ACS National Meetings, news items, etc. For inclusion in the Division Newsletter and webpage, send symposium information to the Division Business Manager (Ruth Hathaway) for forwarding to the Newsletter Editor and webmaster. Program Development Firm up offered papers. As soon as a paper is promised, send the author a letter of thanks stating deadlines for abstracts and copies of the Extended Abstract Instructions and any other pertinent information. Contact the authors at least every three months giving a progress report on program development, publication plans, etc. Maintain enthusiasm, momentum, and a sense of the scientific importance of your symposium. Do not promise a speaker a specific time slot. Tell them most presentations are expected to be 20 min (total 15 min allowing 5 min for discussion). Special cases may be allowed more. A8-4 Appendix 8 GUIDELINES FOR SYMPOSIUM ORGANIZERS (continued) Several months before the deadline for submission of abstracts (ACS and Extended) for inclusion in the ACS meeting, review your list of papers, tentatively group them into sessions, and look for any serious omissions or margin/style violations. You may need to have the author revise the abstracts to fit within the allotted space, add the proper heading, etc. If the author cannot or does not correct the error, do so yourself. Fill in the areas needing attention by obtaining more papers, guiding authors, or covering the areas in your introductory remarks, which can be published. Program Requirements Reaffirm your meeting size with the Program Chair. Check other programs for conflicts using OASYS. Review incoming abstracts for content and compliance with abstract instructions. If abstracts do not comply, return to authors for revision before sending them to the Business manager. Send the Division Extended Abstracts for each presentation, the Proposed Symposium Format, and a Proposed Session format for each session to the Business Manager TO BE RECEIVED NO LATER THAN May 1, 2005, to permit evaluation of time requirements, program conflicts, etc. and in order that the Program Chair can, in turn, meet ACS deadlines. The Business Manager (R Hathaway) must receive the extended abstracts (by email or floppy disc) by this date. Answer requests from ACS headquarters and the Division Program Chair for preliminary programs, advance publicity, teleconferencing potential, and final programs promptly. Most of this is handled through the Program Chair but must originate with the Symposium Chair. Be available by phone or email about two weeks before the program publication deadline dates, or designate someone else to negotiate final scheduling of your program. Symposium Publication Symposia of scientific value and/or public interest may be publishable and the Division strongly encourages publication of such material. The Division has a publishing agreement with the American Chemical Society (American Chemical Society, 1155 Sixteenth Street, N.W., Washington, DC 20036, Phone 202-872-4600). ACS books must be granted the first right of refusal before the book can be offered to another publishing house. Details of the publishing arrangement and Division requirements may be obtained from the Program Chair on request. Miscellaneous Some symposia are co-sponsored by more than one ACS division. Coordination with the other divisions is usually done by the Division Program Chair; however, it is appropriate for the symposium organizers to make suggestions and preliminary contacts, etc. Other divisions may have different requirements for abstracts, publications and deadlines. The Division has limited funds for guest registration of foreign scientists and American nonchemists. Check with the Division Program Chair for details if you have a need. If you have specific questions or desire clarification, call or email the Division Program Chair or Business Manager. CALL FOR PAPERS [EXAMPLE] A8-5 Appendix 8 THE FATE OF SYNTHETIC CHEMICALS AND PESTICIDES IN SOIL AND AQUATIC ENVIRONMENTS [EXAMPLE] Division of Environmental Chemistry 224th American Chemical Society (ACS) National Meeting August 18-22, 2002 Boston, MA Synthetic chemicals and pesticides are widely distributed in the environment through indirect losses or direct application to the soil and water. Many of these chemicals are toxic to animals and the biota and accurate information about their movement and fate in these environmental compartments is essential to conducting and reliable risk analyses for these chemicals. A wide variety of physical, chemical and biological processes move these chemicals and transform them into new chemical species with new sets of physical and chemical properties. This symposium will present research concerning fate processes for chemicals, environmental fate and effects modeling and results of investigations of the fate of specific chemicals in soil and water. Presenters are required to submit a short abstract to the ACS by April 25, 2005, using the the ACS online system (OASYS) at http://oasys.acs.org/. This division also requires an extended abstract of two or more pages that must be submitted to the symposium organizer by May 1, 2005 using the instructions posted on the web at http://envirofacs.org.

A8-8 Appendix 8 SAMPLE EXTENDED ABSTRACT BRIEF TRIPHENYLTIN EXPOSURE CAUSES IRREVERSIBLE INHIBITION OF THE CYTOTOXIC FUNCTION OF HUMAN NATURAL KILLER CELLS Sharnise Wilson*, Bommanna G. Loganathan and Margaret M. Whalen Department of Chemistry, Tennessee State University, Nashville, TN 37209 *Department of Chemistry, Murray State University, Murray, KY 42071 Introduction Organotin compounds are used as heat stabilizers polyvinyl chloride polymers, industrial and agricultural biocides and as industrial catalysts in variety of chemical reactions1. Triphenyltin (TPT) is an organotin, which is primarily used in agriculture as a contact fungicide to treat wide variety of crops including potatoes, peanuts, carrots, soybeans, sugar beets and rice2-4. TPT is also used in antifouling paints to prevent growth of barnacles and other fouling organisms on aluminum hulled boats and ships over 75 ft. Due to its extensive use, TPT contamination has been reported in water, sediment and fish from both freshwater and marine environments in the United States, Europe and Japan5-8. Laboratory TPT exposure studies have revealed a wide spectrum of toxic effects in aquatic and terrestrial organisms. Immune function studies with rats fed TPT revealed that the thymus dependent immune responses were suppressed including delayed-type hypersensitivity reactions.Triphenyltin hydroxide produced tumors in rats and mice4,9. Human exposure to phenyltins (PTs) might come from occupational exposure and/or consumption of contaminated food. Very limited information is available on the toxic effects of TPT in humans. Because of the deleterious effects of this compound, the Occupational Safety and Health Administration (OSHA) has established workplace exposure limits of 0.1 mg m3 of air for organotin compounds4. The Food and Agricultural Organization of the United Nations/ World Health Organization’s (FAO/WHO) proposed a provisional tolerable daily intake (TDI) of 0.5 µg TPT/kg body wt/day 10. Natural Killer (NK) cells are lymphocytes capable of killing tumor cells, virally-infected cells and antibody-coated cells. NK cells are the earliest and possibly predominant defense against tumor cells11. Human NK cells play a central role in immune defense against virus infection and formation of primary tumors11. Previously, we have shown that exposure to TPT (1 mM for 1 h) greatly reduced the ability of NK cells (obtained from peripheral blood of adult male and female volunteer donors) to kill K562 (human chronic myelogenous leukemia) tumor cells12. The ability of NK cells to lyse tumor targets was measured using a 51Cr release assay12. In this study we examined whether the inhibition of NK-cell cytotoxicity induced by a brief (1 h) exposure to TPT could be reversed if the TPT was removed and the cells were allowed to incubate for up to 6 days in TPT-free media. A8-9 Appendix 8 Material and Methods Blood Sampling and Isolation of NK Cells Peripheral blood samples from healthy adult (male and female), volunteer donors were used for this study. Whole blood was applied to Ficoll-Hypaque (1.077 g/ml) and centrifuged at 500 g for 30 min. to remove red blood cells. Mononuclear cells were collected from the Ficoll-Hypaque and washed twice (250 g, 10 min.) with phosphate buffered saline (PBS). In order to remove platelets, the cells were suspended in a small volume (2.5 - 5 ml) of PBS and layered on to 2.5-5 ml of bovine calf serum (BCS) and centrifuged at 200 g for 5 min. The pellet was resuspended in PBS and the process was repeated. The cells were then suspended in complete medium which consisted of RPMI-1640 supplemented with 10% heat-activated BCS, 2 mM L-glutamine and 50 U penicillin G with 50 µg streptomycin/ml. Non adherent cells (30-40% CD16+, 60-70% CD3+) were prepared by incubating the cells in glass Petri dishes (150 X 15 mm) at 37 °C and 5% CO2 for 1 h.12-14. Chemical Preparation TPT was purchased from Aldrich Chemical Co. WI, USA. Dimethylsulfoxide (DMSO) was obtained from Sigma Chemical Co. St. Louis, MO, USA). A Neat standard was resuspended in DMSO. TPT was diluted in gelatin media (0.5% gelatin replaced the calf serum in complete medium) to achieve a final concentration of 750 nM (the final concentration of DMSO did not exceed 0.0005%. Cell Viability and Cytotoxicity Cell viability was determined by trypan blue exclusion. Prior to assay, the NK cells were separated by centrifugation from complete medium (RPMI 1640) and transferred to gelatin media. Cell numbers and viability were assessed at the beginning and end of the assays. Cell numbers and their viability did not vary among experimental conditions. NK cytotoxicity was measured using a 51Cr release assay12-14. The target cell in all cytotoxicity assays was the NK-susceptible K562 (human chronic myelogenous leukemia) cell line. An appropriate number of K562 cells were incubated with 51Cr in 1 ml of BCS for 1.5 hr at 37 °C in air/CO2 (19:1). The cells were then washed twice with gelatin medium. NK (effector) cells (5.0x105/100 µL for 50:1 ratio) were added to the wells of round-bottom microtitre plates. The effectors were diluted to 25:1 ratio (2.5x105/100 µL), and 12.5:1 ratio (1.25x105/100 µL); each ratio was tested in triplicate. Targets were added (1x104/100µL) to each well, and the plate was centrifuged at 150 g for 3 min. and incubated for 2 hr at 37 °C ( air/CO 2 ,19:1). After incubation 0.1 ml aliquot of the supernatant was collected and counted for radioactivity for 60 sec in a Packard COBRA gamma counter (Packard Instrument Co., Meriden, CT, USA) gamma radiation counter. Specific lysis was calculated as follows: 100x[(test c.p.m spontaneous c.p.m.)/maximum c.p.m.- spontaneous c.p.m.)]. Maximum release was produced by adding 100 µL of 10% Triton X-100. Results and Discussion Lymphocytes were exposed to 750 nM TPT for 1h. The concentration of TPT used in treating the cells was a concentration that reduced cytotoxic function by between 5070% after a 1 h exposure, while not affecting cell viability. Following the exposure A8-10 Appendix 8 period, the TPT containing media was removed and replaced with TPT-free media. The cells remained in TPT free media for varying lengths of time (0, 24 h, 48 h, 4 days and 6 days) and were assayed for cytotoxic function using a 51Cr release assay. Figure 1 shows the percent inhibition of NK cytotoxicity when NK cells were exposed to 750 nM TPT for 1h followed by a 0 h, 24 h, 48 h, 4 d or 6 d period in TPT-free media at the 50:1 lymphocyte: target ratio. When the cells were assayed for cytotoxic function immediately after a 1 h exposure to 750 nM TPT (0 h recovery) there was a 57±10% decrease in NK-cytotoxic function at the 50:1 ratio, (n=12). When TPT-exposed NK cells were allowed to incubate in TPT-free media for 24 h (24 h recovery period), NKcytotoxic function was decreased by 840±15% at the 50:1 ratio (n=12). Specific lysis was decreased by 83±25% following a 48 h incubation in TPT-free media (n=9, 50:1 ratio). A 1 h exposure to 750 nM TPT followed by a 4 d incubation in TPT-free media produced an 86±19% inhibition of cytotoxicity (n=6, 50:1 ratio). After a 6 day incubation period in TPT-free media cytotoxicity was reduced by 98±4% at the 50:1 ratio (n=6). Thus, there was no significant recovery of cytotoxic function even when the NK cells were allowed to incubate in TPT-free media for up to 6 days. There was a significant difference in percent inhibition of cytotoxicity between the 0 h recovery time and all other recovery time points (p<0.001) when a pair wise comparison was carried out using Student's t test. That is, there was a greater decrease in cytotoxic function in the cells that were given a recovery period than in those that were given no recovery period (0 h in TPT-free media). This indicated that exposure to TPT induced changes in the NK cells that lead to an increased inhibition of function even in the absence of compound in the media. This indicated that TPT was acting as an irreversible inhibitor of cytotoxic function whose effect(s) increased with time. FIGURE 1 Triphenyltin hydroxide appeared to have an effect on immunity in both rats and mice as shown by the moderate changes in immunoglobulins IgG, IgA, IgM in both males and females4. An accidental exposure of phenyltin lead to death of a female worker reported following renal failure 12 days after exposure15. Human exposure to TPT can occur by multiple routes (occupational exposure during the manufacture, application in the agricultural fields, consumption of contaminate fish from coastal as well as freshwater ecosystems etc.). Since human exposure to PTs is possible as evidenced by the presence of these compounds in fishery products20 and there are demonstrated negative effects of these compound on NK cell function in as little as one hour. There is a need for further studies dealing with the mechanism by which TPT disrupts essential immune functions such as NK cytotoxicity. References 1. Kimbrough, R.D. (1976). Environ.

A8-12 Appendix 8 INSTRUCTIONS FOR POSTER SESSION AUTHORS • Each poster paper "booth" will have a horizontal poster board measuring 4' x 6', and the number of the poster paper assigned to that booth. • All illustrations, charts, and textual material to be posted must be prepared in advance, since materials for these purposes will not be available at the meeting. • Although you may be scheduled to be present for only a portion of the poster session, your paper should be mounted prior to the opening of the session, and left in place until the close. While required to be present only for a time period assigned to your presentation, you are encouraged to be present for the entire time. • You must have a heading (with lettering at least 1-1/2" high) giving the title of the paper, the author(s), and their affiliation(s). • Illustrative material will have to be read by attendees from a distance of 3' or more, so lettering on illustrations should be at least 3/8" high or typed with a BULLETIN typewriter. • There should be a logical sequence (introduction, development and conclusion) to your display. Each sheet should be numbered. • Although it is not necessary to be too "arty," the effectiveness of your presentation will be enhanced by mounting the sheets on colored construction paper and/or other techniques to improve the graphic impact. Simplicity, ease of reading, etc., are more important than artistic flair. Certain color combinations, for instance, may look beautiful, but be almost impossible to read--especially in the absence of optimum lighting. • Illustrations should NOT be mounted on heavy stock, since they may prove difficult to mount on the poster boards. • Each author is responsible for mounting his/her material prior to the opening of the poster session, and for removing it immediately after the close of the session. The ACS cannot assume responsibility for materials beyond those time limits. • Authors may provide sign-up sheets to record names and addresses of attendees who might wish more information, reprints, etc. • Authors may wish to bring duplicated copies of their data and conclusions. No duplicating facilities will be available at the meeting. • ACS will provide a reasonable supply of push-pins, (although it would be wise to bring your own), masking tape, felt-tipped pens, and will arrange for blackboards to be available in the room, if requested.
