(Q)SAR models could provide useful information on impurities of unknown toxicity, and they have become one of the most important tools to assess the equivalence of a new source (TC/TK) when compared to the reference source. Along with this, an increasing number of countries and organizations (e.g., EU countries, Australia, Brazil, FAO/WHO) requires the applicants to perform (Q)SAR analysis for new/increased levels of impurities in their technical grade active ingredients via pesticide registration by equivalence. In our upcoming webinar, REACH24H will discuss basic concepts, requirements in different countries, application of expert knowledge, establish an acceptable upper limit concentration and uncertainty analysis for (Q)SAR application in assessing the toxicological equivalence of technical grade active ingredients. And beyond that, REACH24H will also share our practices on (Q)SAR applications in toxicological evaluation of new pesticide active ingredients as well as identifying relevant impurities/metabolites in accordance with China pesticide regulation.
