The project has achieved consensus on improving the data structure and filling method under the existing framework of the chemical substance toxicology database through several meetings and ensured the quality of data through data verification management mechanisms such as within-group review and cross-check. On this basis, the information on announced 344 toxic and concerned chemical substances has been established and updated, including information on 250 new substances and updates on 94 primal substances. With the new addition and update of substance data, the contents of the toxicology database dictionary and statistical table have been revised to improve the correctness and completeness. In addition, the database system retains the flexibility of field integration and expansion to meet future needs and adds blank for filling in supplementary information in most fields to provide space for special data. In order to increase the convenience of use, the data export format has been added to 3 types, including PDF, XML and excel, and the latest content of the system can be captured in real time. Arranged two expert consultation conferences to discuss the major changes and discoveries in the content of the database, including data grouping, newly included BSAF data, and suggestions for adjusting the basic information of substances. In the future, it is recommended to prioritize the inclusion of newly announced toxic and concerned chemical substances, and then gradually include existing chemical substances.
