For those coming to the SETAC North America 40th Annual Meeting, which will be held from 3–7 November 2019 in Toronto, Canada, plan on taking advantage of a collaborative and interactive workshop designed to look closely at toxicity testing accreditation in Canada and the United States. Representatives from the Canadian Association for Laboratory Accreditation, Environment and Climate Change Canada, the NELAC Institute (TNI) and the U.S. Environmental Protection Agency will be speaking on various topics related to laboratory testing and accreditation.

The Whole Effluent Toxicity (WET) Methods, Laboratory Training and Accreditation Workshop will be held from 10:00 a.m.–2:30 p.m. on Friday, 1 November in north Toronto. For those not attending the SETAC annual meeting, you are more than welcome to make a trip to Toronto for this workshop. There is no fee to attend the workshop, and the tentative subjects that will be addressed are as follows:

  1. Laboratory Accreditation Processes
  2. Laboratory Training and Assessment Requirements
  3. Approaches to WET Data Analyses
  4. Up Front Processes Necessary for Obtaining Successful Testing Outcomes
  5. Confounding Factors Observed in WET Tests
  6. Reduced Organism (Fish) Usage During Testing Programs

We hope you are able to come to share your thoughts and perspectives in the discussion. We welcome any suggestions for discussion topics and will address other related questions.

To RSVP for the workshop, please email Stephen Clark at or call him at (707) 207-7766.
