Purpose.   The award was established in honor of the founders of the Division and recognizes scientists whose work exemplifies the founders’ vision of excellence in the field of chemical toxicology. Nominees should be members of the Division of Chemical Toxicology whose scientific activities have emphasized innovative research in the general field of chemical toxicology.

Dick Loeppky
Dick Loeppky

The Richard Loeppky Lecture.  Richard Loeppky began studying nitrosamine chemistry in the mid 1960s.  In the ensuing decades, Loeppky’s group used the tools of mechanistic chemistry to shed light on carcinogenic N-nitroso compounds. His work centered on the definition of the bioactivation pathways of environmental and metabolically-generated ß-oxidized nitrosamines and the exploration of new nitrosation mechanisms for the generation of endogenous and exogenous nitrosamines.

Loeppky’s research in the field of nitrosamine carcinogenesis led to his central role in conceiving and establishing the Division of Chemical Toxicology. In the early 1990s, he and others recognized that there was no appropriate venue for the presentation of work in this field.  This led to the idea that chemical toxicology could be represented by a new division of ACS.  Loeppky’s dedication to the cause was substantial. He was instrumental in developing a petition, recruiting a leadership group and, most importantly, obtaining permission from various ACS committees and individuals to mount a drive for a new division. He also secured the approval of the existing ACS divisions and the ACS president. The division was granted probationary status and presented its first program at the Orlando meeting of the ACS in August 1996.

With this Lecture, we honor the creativity, enthusiasm, and the work of Richard Loeppky.

The Division of Chemical Toxicology (TOXI) will make available Travel Assistance Awards to undergraduate and graduate students and postdoctoral researchers. The awards of approximately $750 will reimburse travel and hotel costs for the ACS meeting in Philadelphia this August (receipts will be required). Applications will be awarded on the basis of financial need, scientific merit, and diversity factors. Preference will be given to first-time attendees.

All students and postdocs who are members or affiliates of TOXI and who have submitted an abstract for the National ACS meeting in Philadelphia are eligible to apply.

The application should consist of:

  1. A nomination letter from the faculty advisor or laboratory director. The letter should explain why Travel Assistance Award funds are needed.
  2. A curriculum vitae for the applicant.
  3. The abstract for the work to be presented by the nominee at the meeting.

Applications are due by July 8th, 2016.

The Program Committee will evaluate proposals based on their ability to attract and engage a large audience, timeliness, and appropriateness for the Division of Chemical Toxicology.

The Executive Committee seeks proposals that span the interests, and fully reflect the diversity of the membership in the Division. Therefore, selection of speakers should be balanced when considering gender, groups historically underrepresented in the profession, research area, employment sector, and career stage.

  • Proposals are due on July 15 ONE YEAR prior to the meeting where the session is requested.  For example, for a symposium in Fall 2018, the due date is July 15, 2017.
  • Proposals should be a maximum of ONE page (12 point font, 0.5 inch margins).

The proposal must contain (see the Template/example below):

  • A symposium title.
  • A paragraph stating the idea behind the proposal, why it is timely,  how this symposium will differ from those recently given at TOXI, and  why TOXI is the appropriate forum for this symposium. (Chemical mechanisms of toxicology)
  • Indicate your willingness to organize this symposium at a different (later) time than originally proposed.
  • A list of potential speakers, preferably with tentative titles (4-6 speakers is a typical number submitted).
  • The names of several alternative speakers for the session should be included.
  • The speaker’s status should be listed as outlined in the template
    Please use the template provided below for the proposal.
    E-mail national meeting symposia proposals to Thomas E. Spratt
  • Proposals will usually be considered for a half-day session only.
  • Academic speakers are eligible for reimbursement of reasonable travel expenses
  • Industrial speakers are eligible for reimbursement on a case-by-case basis.
  • Speakers working for the government or a non-profit institution are eligible for reimbursement.
  • Typical reimbursement for an academic speaker would include:
    • Travel – Non-refundable round trip coach airfare to the meeting (usually up to $500).
  • ACS members are expected to pay their own registration fees.  Non-ACS members can get reimbursed for a one-day registration.
    • Accommodation – Two night’s stay in a hotel (please choose one from the ACS list, if possible).
  • Miscellaneous – Other reasonable travel expenses (taxi, tolls, etc.), but not meals, during the trip.
  • Reimbursement amount outside the guidelines is at the discretion of the session organizer and Divisional Treasurer.
  • Symposium organizers are eligible for reimbursement within the above guidelines.
  • The symposium organizer will collect all original receipts from the speakers, and submit them to Secretary-Treasurer using the reimbursement form.

Any funds that are raised by the organizer are technically donated to the TOXI, which formally funds the symposia at the National Meetings. Symposium organizers should manage the overall expenses for their symposium on behalf of the TOXI, so please be sure to let the speakers understand the guidelines before the symposium to avoid misunderstandings.

As an organizer, it is your responsibility to determine the distribution of available funds. This is critical when there are not enough funds to pay all of the expenses encumbered by invited speakers. In this case, you must indicate to the Secretary/Treasurer the level of partial reimbursements to be accorded to each speaker.
