After the 7th meeting of the Conference of the Parties to the Stockholm Convention, Taiwan added Dichloronaphthalene and other 4 substances into the TCSL and is now regulated as a Class 1 toxic chemical substances. So far 310 substances are regulated as toxic substances in Taiwan, including:
112 Class 1 substances
100 Class 2 substances
72 Class 3 substances
92 Class 4 substances
(Note* some overlap exists among Class 1, Class 2 and Class 3)
The details of the newly added 5 substances are specified as below.
Listed No. | Series No. | Chinese Name | English Name | Chemical Formula | CAS. Number | Control concentration standard w/w (%) | Large-scale handling standard (kg) | Toxicity Classification |
094 | 01 | 二氯萘 | Dichloronaphthalene | C10H6Cl2 | 1825-31-6 | 1 | 50 | 1 |
094 | 02 | 三氯萘 | Trichloronaphthalene | C10H5Cl3 | 1321-65-9 | 1 | 50 | 1 |
094 | 03 | 四氯萘 | Tetrachloronaphthalene | C10H4Cl4 | 1335-88-2 | 1 | 50 | 1 |
094 | 04 | 五氯萘 | Pentachloronaphthalene | C10H3Cl5 | 1321-64-8 | 1 | 50 | 1 |
094 | 06 | 七氯萘 | Heptachloronaphthalene | C10HCl7 | 32241-08-0 | 1 | 50 | 1 |
In addition to adding substances, Taiwan authority also revised the regulated control concentrations for another 5 substances. The concentration threshold under control was lowered via this revision, which means a stricter management was imposed on the following five toxic substances.
Listed No. | Series No. | Chinese Name | English Name | Chemical Formula | CAS. Number | Control concentration standard w/w (%) | Large-scale handling standard (kg) | Toxicity Classification |
050 | 01 | 丙烯醯胺 | Acrylamide | CH2CHCONH2 | 79-06-1 | 30 (Previous: 50) | 50 | 2,3 |
066 | 01 | 甲醛 | Formaldehyde | HCHO | 50-00-0 | 15 (Previous: 25) | 50 | 2,3 |
075 | 01 | 1,2-二氯乙烷 | 1,2-Dichloroethane ( Ethylene dichloride) | CH2ClCH2Cl | 107-06-2 | 15 (Previous: 25) | -- | 4 |
165 | 01 | 壬基酚（壬酚） | Nonylphenol | C6H4(OH)C9H19 | 25154-52-3 84852-15-3 | 5 (Previous: 10) | 50 | 1 |
165 | 02 | 壬基酚聚乙氧基醇 | Nonylphenol polyethylene glycol ether | (C2H4O)nC15H24O | 9016-45-9 26027-38-3 | 5 (Previous: 10) | 50 | 1 |
Transitional measures have been provided for the above mentioned 10 toxic chemical substances in terms of substances handling, release quantity recording, transportation, etc.
Taiwan authority also prohibits the use of Endosulfan, Alpha (α) endosulfan, Beta (β) endosulfan and Endosulfan sulfate in pesticides via this revision.
