Background

Three other substances (CAS RNs 122-68-9, 24448-20-2 and 43048-08-4) were identified as being a part of the Acrylates and Methacrylates Group at the outset of the third phase of the CMP. These substances were subsequently determined to be of low concern to both human health and the environment, through other approaches. The conclusion for CAS RN 122-68-9 is provided in the Screening Assessment of Substances Identified as Being of Low Concern based on the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances. Conclusions for CAS RNs 24448-20-2 and 43048-08-4 are provided in the Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
