This project commenced on January 12, 2023. The primary is focused on four aspects, including grasp the chemical substances situation in industrial operations and establish baseline data, enhance chemical substances sampling and testing techniques, promoting inter-ministerial cooperation for border management of chemical substances as well as implementing e-commerce inspections of toxic chemical substances (TCSs) and concerned chemical substances (CCSs). In the section regarding the understanding of the chemical substances situation in industrial operations and data collection, the investigation of the purposes of chemical substances operations aims to collect data on industrial manufacturing processes for future assessments. In this instance, the focus was on 15 newly concerned chemical substances that might be used by various operators. A market survey was conducted with 40 operators to gain insights into the operation of these chemical substances. Apart from investigating how these chemical substances are used, data was also collected on other chemicals simultaneously used within the operators' facilities. This information encompassed aspects such as substance appearance, applications, final products, and the chemical composition ratios. Additionally, the distribution of downstream manufacturers was tracked to understand the chemical supply chain. Furthermore, operators were provided guidance in creating pollution flow diagrams. Additionally, in the section focused on the investigation of importers dealing with TCSs and CCSs products, we have completed surveys of importers dealing with products containing mercury, asbestos, nonylphenol/nonylphenol polyethoxylates and prfluorinated products. This survey aimed to confirm the types of imported products,applications and distribution. To enhance chemical substances sampling and testing techniques, this year, we have gathered and compiled relevant information on domestic and international testing methods for Perfluorohexanesulfonic acid (PFHxS), Per- and Polyfluoroalkyl Substances (PFAS), γ-Butyrolactone (GBL), cyclopentane, and 2-chloroethanol. After analyzing the testing methods announced by domestic and international governments and credible organizations, we have developed standardized testing methods that can be used as references for regulatory authorities. In addition to this, we have completed 20 on-site sampling sessions and tested 200 samples in accordance with the requirements of the regulatory authorities. The sample is tested from four aspects:sample verification by Chemical Administration, sample submission by Environmental Protection Bureau,border sampling and factory sampling. Furthermore, in the field of aquatic ecotoxicity testing, we have conducted toxicity tests on native species such as Oryzias sinensis (freshwater fish) and Neocaridina denticulata (freshwater shrimp) for nickel aminosulfonate and furfuryl alcohol. To promote inter-ministerial cooperation for the management of border chemical substances, we have also collaborated with the Customs Administration to conduct 20 border sampling operations. Additionally, to assist the Chemicals Administration and Environmental Protection Bureau in understanding the application of optical principles in chemical inspection cases and in customs clearance operations related to border risk detection, we organized an educational training session on October 18th. In the e-commerce inspections, we conducted electronic searches for 341 TCSs and 18 CCSs on 15 domestic online shopping platforms. After establishing a keyword list, we electronically checked high-risk products and then manually reviewed the results. This process resulted in a total of 56,810 entries in the risk list. Following manual evaluation, 229 items were flagged as suspicious products, of which 9 were confirmed to be in violation. The 9 non-compliant products have been successfully removed from the platforms, with approval from the Chemical Administration, and communication was established with the respective platform administrators.
