A video recording and slides are available from a January 22 webinar titled “CATMoS: Development and Use of the Collaborative Acute Toxicity Modeling Suite,” presented by the PETA International Science Consortium (PETA-ISC). Links to recordings of all webinars in the PETA-ISC series on “Use of New Approach Methodologies in Risk Assessment” are available at https://www.piscltd.org.uk/nam-webinars/.

In this webinar, NICEATM Acting Director Nicole Kleinstreuer and Kamel Mansouri, ILS (contractor supporting NICEATM), discussed development of CATMoS, a free resource for screening organic chemicals for acute oral toxicity. Predictions generated by CATMoS compare favorably with performance characteristics of the in vivo acute oral toxicity test. Kleinstreuer and Mansouri also demonstrated how to use the modeling suite to generate acute oral toxicity predictions.
