Abstract Submissions


Why Submit an Abstract?

By presenting at the 2024 SOT Annual Meeting and ToxExpo, you will:

  • Share your research during the leading international forum for toxicologists
  • Engage in open dialogues with some of the 5,000+ attendees for future collaborative opportunities
  • Gain recognition among your peers by having your research published in The Toxicologist, a digital-only publication and an official supplement to Toxicological Sciences, the Society’s journal

Awards Available for Top Abstracts

Many SOT Special Interest Groups and Specialty Sections administer awards for outstanding abstracts. Deadlines vary throughout the year.

Abstract Submissions Closed

Abstracts are no longer being accepted for the 2024 SOT Annual Meeting and ToxExpo. Please consider submitting an abstract for the 2025 meeting when abstract submission opens in August.

About Abstract Presentations

Poster Sessions occur Monday through Wednesday during the SOT Annual Meeting and ToxExpo.

Authors are assigned to a specific Poster Session, and on the day of their assigned session, their posters are displayed all day during ToxExpo hours (9:00 am–4:30 pm), allowing attendees to visit the posters at their convenience. Authors will attend their posters only during the assigned Poster Session time frame. Please consult the Poster Sessions FAQs for additional information.

By submitting an abstract and having that abstract accepted, the author is expected and obligated to pay the meeting registration fee and present the abstract during the assigned Poster or Platform Session. Acceptance notification and session timing/instructions will be sent by email in early January, before the early-bird registration deadline.

Crafting and Submitting Your Abstract

The Scientific Program Committee (SPC) reviews each abstract that is submitted and bases acceptance or rejection on specific criteria. Review this section carefully to better understand that criteria and to gain tips for successfully completing an abstract submission.

Required Content and New Submission Format

Over the last few years, the SPC has noticed that most rejected abstracts fail to include at least one of four main elements. To help ensure that applicants are including the correct content in their abstracts—especially trainees submitting their first abstract—the SPC has updated the application form by breaking the abstract entry into the four required pieces of information. Your abstract length in total—when combining the character count from each required element/box—should be 4,500 characters or less, not including spaces. Please note that your abstract title and the author block (author names, institutions, city, state, country) are included in the 4,500 maximum character count.

Background and Purpose

The first few sentences of your abstract will go in the “Background and Purpose” box of the submission form and should describe why you embarked on this work and your overall purpose or objective.


The next few sentences of your abstract will go in the “Methods” box and will provide a description of how your research was done.


Arguably the most important portion of your abstract are the sentences conveying your results. This means data! If your study is not the kind to produce data, clearly summarize the results and findings. Do not include figures, tables, or chemical structures and avoid nonstandard acronyms.


The final sentences of your abstract should convey the impact or significance of your work to the field of toxicology.

Pitfalls to Avoid

Abstract reviewers first ensure that a submitted abstract clearly describes the background and purpose of the work, the methods used, the results obtained, and the conclusions drawn. From there, the reviewer assesses the quality of this information, and abstracts can be rejected for one of these reasons:

General Concerns

  • The abstract raises ethical questions that need to be resolved before it can be accepted.
  • The writing style is insufficient to clearly describe the goals, approach, outcome, and/or significance of the study.
  • The abstract describes/promotes a commercial project without providing substantive scientific data/results.

Scientific Concerns

  • The experimental design and/or interpretation appears to be flawed or biased.
  • The abstract lacks sufficient data or results, or the abstract is a commentary without sufficient data or evidence.
  • The abstract is one of several emanating from a single study and cannot stand alone.
  • The abstract fails to identify substance(s) being investigated, provide sufficient information on characterization of substance(s), or provide sufficient information on numbers of substances being investigated (in screening projects).
  • The abstract represents a review of published literature without a clearly identified novel interpretation or application, nor sufficient new data or knowledge.
  • The work appears fundamentally sound, but it is unclear in its connection and/or relevance to toxicology.

Additional Abstract Development Tips

  • Details to Describe

    Additionally, authors should consider the following when developing the abstract:

    • Test compounds utilized in the study should be identified in the abstract as much as possible. In cases where the length of the proper chemical name precludes its use, a manufacturer’s identification number, etc., may be acceptable, provided the structure and chemical identity of the compound are included in the presentation. Abstracts may not be accepted if the authors are unable to disclose the chemical identity of the compound(s) used in the study. It is very common for Poster Session Chairs to present a poster in the session that they are chairing; this is why SOT assigns two Chairs per Poster Session. You may split the poster Chair duties with the other Chair. If the other Chair also is presenting posters during your Poster Session, you are authorized to leave your poster for a few minutes during the session to fulfill the Chair duties as explained in the Poster Session Chair Guidelines.
    • It can be challenging to describe results of “big data” studies within the confines of a 4,500-character abstract. Instead, include specific examples of findings to help meet the requirement for description of data.
    • All animal experimentation must be carried out in accordance with the Society’s Guiding Principles in the Use of Animals in Toxicology.
    • All abstracts submitted with human testing require that IRB protocol has been followed and approval obtained. References are not required in the body of the abstract, but the Scientific Program Committee may request authors to provide the IRB protocol followed.
  • Tips for Non-laboratory or Non-field Studies

    In the case of studies that do not describe laboratory or field experiments, such as reports on educational, ethics, legal, or social initiatives, authors should:

    • Describe the research or assessment approach instead of experimental procedures.
    • Summarize the study’s results or findings explicitly.
    • Clearly articulate the implications for stakeholders.

    In addition, abstracts describing new initiatives or science policy in the regulatory community must clearly describe the impact on the practice of toxicology and/or risk assessment. Care should be taken to clearly distinguish between statements based on documented facts versus opinions. Regarding literature surveys or reviews and background materials, simple overviews or unstructured assessments of a topic, without novel advances in either approach or interpretation of a topic that leads to new conclusions, are discouraged. However, systematic reviews and/or advances in systematic review methods are acceptable abstract submissions.

Authorship and Sponsorship Requirements

Authors are permitted as the presenting author on only one poster abstract for the meeting. There is no restriction on the number of co-authorships. The SOT Scientific Program Committee reserves the right to require consolidation of multiple abstracts submitted from a single study. Each abstract selected for the program must be presented by the presenting author.

SOT membership or sponsorship by an SOT member is required for all abstracts. If an SOT member is unavailable to sponsor the abstract and at least one author is a member of an organization approved for offering sponsorship, the author can indicate a sponsoring organization instead of an SOT member in the Abstract Submission System. By sponsoring the abstract, the sponsor acknowledges that the research has been done according to the SOT Code of Ethics. SOT member sponsorship is limited to Full and Associate members, who may sponsor an unlimited number of abstracts.

Abstract Scheduling

When abstract acceptances are sent in early January, the notifications contain the assigned Poster or Platform Session, including date and time, for each abstract. Once poster and platform presentations have been scheduled, the complexity of the program planning process prevents any changes in the type of session, time, or location of any presentation. There are no exceptions.

Abstract Withdrawals

Written notification of withdrawal of an abstract must be received by SOT Headquarters by January 16 if the abstract cannot be included in the Annual Meeting materials. Any withdrawal requests made after January 16 will be honored by SOT Headquarters; however, based on the date of the request, the abstract may be included in the materials, and a “Withdrawn by Author” sign will appear on the poster board.

  • I would like to submit an abstract for an oral presentation. How do I do that?

    Abstracts that are selected to be presented orally, as opposed to as a poster, are scheduled into Platform Sessions, where speakers have 15 minutes each to deliver a PowerPoint presentation of their abstract.

    You may indicate your interest in this type of presentation at the beginning of the submission process by selecting the option for “Platform or Poster” on the “Presentation Preference” screen. The programming of your abstract into a particular session type will be at the discretion of the Scientific Program Committee.

  • Will SOT accept late-breaking abstracts?

    There will be a late-breaking abstract submission period December 11, 2023–January 18, 2024. The late-breaking abstract submission fee is $90.

    An important criterion for the late-breaking submission period is that the research must be new and of sufficient scientific importance to merit special consideration after the standard abstract deadline. Abstracts should describe high-impact, original research that could not be completed before the original deadline. All late-breaking abstracts will be presented during Poster Sessions on Thursday morning.

  • Because I am not an SOT member, how can I submit an abstract for consideration for the SOT Annual Meeting?

    If none of the authors on your abstract is an SOT member, sponsorship by a Full or Associate member is required. By sponsoring the abstract, the sponsor acknowledges that the research has been completed in adherence with the SOT Code of Ethics. If there is no Full or Associate SOT member available, if at least one author is a member of an approved sponsoring organization, you may indicate that in the Abstract Submission System. A full list of approved sponsoring organizations can be found the “Authorship and Sponsorship” section on this web page.

  • Can I, or my company, be invoiced for abstract submission(s)?

    At this time, SOT can only accept payment by credit card. Accepted credit cards include Visa, MasterCard, Discover, and American Express.

  • How can I obtain a receipt for my abstract submission?

    A “Print Receipt” option will appear in the Abstract Submission System once the abstract fee payment has been approved. Receipts also are emailed to the submitting author. Check your Junk or Spam folder if you do not receive an emailed receipt within 30 minutes of submitting an abstract.

  • If I am unable to attend the SOT Annual Meeting, can I receive a refund for my abstract submission?

    Refunds are not offered for any abstracts that have been submitted for the SOT Annual Meeting. The submission fee covers the costs associated with processing and reviewing the abstracts.

Using the Abstract Submission System

  • How much time do I have to enter my abstract in the abstract system?

    The system has a 120-minute time-out feature. After 120 minutes of inactivity, the system will automatically log you out. If this happens, your entries up to that point WILL BE SAVED, and you will be returned to the place where you left off when you log back in. If you get a “Page Cannot Be Displayed” error, you have probably been logged out.

  • How can I get special characters to copy over if I am using a word-processing application to type my abstract?

    This depends on your browser. For most browsers, you may copy and paste your full title and abstract into the appropriate fields in the abstract system from an MS Word document, and the special characters will be preserved in the abstract system. However, if there is hidden coding embedded in the document you are copying from, the special characters may be replaced with a question mark or other symbols when the abstract is loaded into the Abstract Submission System. Be sure to review the summary page of your abstract submission in the system and check the special characters to make sure they are intact.

  • If I have a conflict of interest to disclose with my abstract, how do I indicate that?

    If you have any conflicts of interest that you need to disclose, please indicate them in the appropriate step in the submission site. If your abstract is accepted, you must include those conflicts on a disclosure slide in your platform presentation or make the disclosure on your poster.

  • I am logged in to the SOT website using my membership information, but the submission site reveals the following message: “Unknown username/password.” Why?

    The submission site does not recognize your SOT membership login information and requires a separate login. However, when you create your Abstract Submission System login, you may use your SOT credentials.

  • If I have to contact SOT Headquarters or the Tech Support team, what information should I have on hand?

    Upon starting the process to submit an abstract, you will be automatically assigned a control ID number. Once you have completed the abstract submission process, please keep a copy of the submission confirmation for your records, including your control ID number. You will need your control ID number to communicate with SOT Headquarters and/or the Tech Support team about a specific abstract.

Poster Session FAQs

  • Will authors be asked to attend their posters all day?

    No. Presenting authors will attend their posters during their assigned Poster Session time frame, but the poster will remain displayed during ToxExpo hours.

    The presenting authors are encouraged to include an email address or other contact information on their poster so attendees who view the poster when the author is not in attendance can contact the authors with questions or other information. Uploading an ePoster provides additional viewing opportunities for attendees.

    Poster Sessions and their corresponding time blocks are defined by topic (e.g., neurotoxicology, metals) so that attendees interested in that topic have access to all authors at the same time. In addition, the Scientific Program Committee will make every effort to ensure that no Scientific Sessions, including Platform Sessions, related to a specific topic occur during the same time period as the Poster Session for that topic.

  • What if a sudden time conflict arises and I—or any co-author—cannot attend my poster during the designated Poster Session time frame?

    SOT understands that sudden scheduling conflicts can arise. All presenting authors are encouraged to include an email address or other contact information on their poster so attendees who view the poster when the author is not in attendance can contact the authors with questions or other information. Presenting authors also are highly encouraged to upload an ePoster to provide additional viewing opportunities for attendees.

  • How are Poster Session times and locations in the ToxExpo Exhibit Hall assigned by the Scientific Program Committee?

    Poster Sessions and their corresponding time blocks are defined by topic (e.g., neurotoxicology, metals) so that attendees interested in that topic have access to all authors at the same time. In addition, considerable effort is made to group similar topic Poster Sessions together in the same color-coded area in the ToxExpo Exhibit Hall. Finally, the Scientific Program Committee makes every effort to ensure that no Scientific Sessions, including Platform Sessions, related to a specific topic occur during the same time period as the Poster Session(s) for that topic.

  • If authors are not standing by their posters all day, how can photography be monitored?

    SOT policy is to not allow any photography of posters unless permission is expressed by the author. SOT staff and security staff will be enforcing the “no photography” policy on-site to curtail concerns about the all-day display format. “No Photography” signs will be displayed on all poster boards. Attendees who violate the no photography policy risk ejection from the Annual Meeting.

  • What time in the morning should authors mount their posters?

    On Monday through Wednesday, authors may enter the ToxExpo as early as 7:30 am to mount their posters. Poster presenters will be admitted into the ToxExpo provided they have an Annual Meeting badge and are carrying a poster; a badge alone will not allow entry prior to 9:00 AM. As soon as you have mounted your poster, please remain by the poster board or depart the exhibit hall until the ToxExpo opens. If you wander around the ToxExpo prior to 9:00 AM, you will be asked to leave by security.

  • What time in the afternoon should authors remove their posters?

    Poster “tear-down” will occur between 4:15 pm and 4:30 pm Monday through Wednesday.

  • What if an author forgets to remove the poster in the afternoon?

    Poster presenters should remove their posters by 4:30 pm each day. Posters left on boards after 4:30 pm on Monday and Tuesday will be removed and placed on retrieval tables located throughout the ToxExpo.

    ToxExpo closes on Wednesday at 4:30 pm. Remaining posters will be gathered and placed on retrieval tables in the Late-Breaking Poster Session room on Thursday morning. Any posters unclaimed by 11:00 am on Thursday will be destroyed.

  • How will author compliance to the all-day poster policy be monitored?

    Authors are required to have their poster mounted on the board for the full duration of the ToxExpo hours (9:00 am–4:30 pm). Poster Session Chairs will be assigned to assist authors during the Poster Sessions, to note any empty boards, and to check compliance with the all-day poster display requirement.

  • I am presenting a poster in a Poster Session that I am chairing. How should I handle this?

    It is very common for Poster Session Chairs to present a poster in the session that they are chairing. If you are Chair in a Poster Session you are presenting in, you may leave your poster a few times during the 2-hour poster session time to fulfill your Chair duties.

  • What rationale goes into programming Poster Sessions in a particular order?

    The SOT Scientific Program Committee traditionally groups Poster Sessions into daily slots based on topic. For example, the Arsenic Toxicity, Toxicity of Metal Mixtures, and Metal Toxicity Poster Sessions would occur on the ToxExpo floor at the same time. Keep in mind that all accepted posters must be displayed all day during ToxExpo hours, but authors will attend their posters only during the assigned Poster Session time frame.

  • Why do Poster Sessions begin in one cluster of poster boards on the ToxExpo floor and then continue in another cluster several feet away?

    Not all poster board clusters on the ToxExpo floor contain the same number of boards, and not all Poster Sessions contain the same number of posters. Therefore, ensuring that all Poster Sessions begin and end in the same poster board cluster is extremely difficult.

    To resolve this issue, the SOT Scientific Program Committee would need to set a minimum and maximum number of poster abstracts accepted per Poster Session so the sessions would contain an equal number of boards within the same cluster, which would limit the number of poster abstracts accepted. The current policy is to assign no more than 40 posters to a Poster Session, while the minimum is five posters for a Poster Session.

    Signs are used throughout the poster board areas to help attendees and poster presenters locate sessions and specific poster presentations.

  • Why are the poster board clusters scattered throughout the ToxExpo Exhibit Hall instead of all together?

    Poster boards are strategically placed throughout the ToxExpo Exhibit Hall to optimize the experience of attendees and exhibitors by creating an ease of movement throughout the hall.
