Read-across: Principle, case study and its potential regulatory application in China.

Read-across, has generated much attention and has been used in many regulatory schemes as an alternative approach to testing globally. The regulatory application of read-across in the chemical management in China is progressing but still limited. A workshop on the "Read-across: Principle, case study and its potential regulatory application in China", organized by the Chemical Risk Assessment Specialty Group under the Committee of Industrial Toxicology of Chinese Society of Toxicology, was held on May 28, 2019 to discuss the potential broader application and acceptance of read-across to support chemical risk assessment in China. The Workshop included global experts from regulatory agencies, academia and industry. Scientific presentations and constructive discussions raised awareness on the use of read-across in different regions, identified barriers to regulatory acceptance, and participants also brainstormed on practical strategies to help facilitate the further regulatory application of read-across approaches in China.
