This project focused on four aspects, including industry usage of chemical substances and establishing baseline data, strenuous 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). For industry survey of TCSs and CCSs and establishment of baseline data, the project provided 27 assessment reports of CCS handlers as well as importers of asbestos and mercury-added products, with 60 handlers investigated. In addition to 27 reports concerning handling of CCSs, handlers’ usage of other chemical substances, including substance appearance, purposes, end products as well as chemical compositions, were gathered. Downstream manufacturer distribution was simultaneously tracked to understand chemical product supply chains and provide enterprises consultation with pollution flow diagram creation. For importers of asbestos-added products, according to 64 first-time importers in 2021, over 81% importers actually imported non-asbestos products, and were counseled to choose c.c.c. code correctly. 12asbestos-added product importers were counseled to use alternatives. In addition, restrictions on importing of mercury-added products had been implemented since January of 2021. Currently, 1 enterprise has acquired import approval visa documents for their mercury-added product, a Solid State Relay (SSR). We assisted Toxic and Chemical Substances Bureau (TCSB) in onsite investigation on July 4th, 2022. Consulted imports should have permit number assigned and report handling records periodically. For reinforcement of sampling and testing technologies for chemical substances, this project gathered 27 assessment reports regarding CCSs. Standard testing methods were provided for competent authorities for references by comprehensively studied and analyzed chemical substance testing methods of domestic and foreign governments as well as credible institutions, followed by further evaluation of feasibility and amendments by environmental analysis organizations. In compliance with authorities, this project performed 35 field samplings and 319 sample tests. Testing samples were mainly submitted from county/municipal Environmental Protection Bureaus (EPBs), market products and the border. In addition to aquatic organism toxicity, aniline and allyl alcohol, known for their high handling capacity, water-solubility and biotoxicity properties, were conducted toxicity tests on Chinese rice fish and Neocaridina denticulate (freshwater shrimp). For promotion of inter-ministerial cooperation for border management, the B＆W Tek TacticID-1064 Handheld Raman Analyzer was utilized. 27 announced CCSs were priority targets and 17 CCSs were established. Furthermore, 219 chemical substances were established in the Raman Spectroscopy database. To familiarize TCSB and EPB with the analyzer, 1 workshop was held on November 4th. The participants were introduced to the analyzer, practice, lab testing and demo. For e-commerce inspections, e-search was carried out across 14 domestic ecommerce platforms. To screen high risk products, a list of keywords was established, followed by online inspection of 341 TCSs, 3 CCSs as well as to be announced CCSs. A list of 56,481 products with risk were selected electronically and double checked manually. 180 uspicious products were manually verified. After notifying their respective platforms, all concerned products were removed.
