Ngomhla ziyi-18 kuMasingana 2024, i-ECHA yashicilela umbiko wokuhlola ukuze ihlole ukuthi ukusetshenziswa kwalawa ma-benzotriazole amane ezihlokweni, okuhlanganisa i-UV-328, UV 327, UV-350, ne-UV-320, kufanele kukhawulelwe ngokuvumelana ne-REACH Article 69(2).
Lezi zinhlobo ezine ze-benzotriazoles zihlanganisa:
| Ukungena kwe-Annex XIV | Igama lezinto | Isifinyezo | EC | I-CAS CHA. | Impahla yangaphakathi |
| 51 | 2-(2Hbenzotriazol-2-yl)- 4,6- ditertpentylphenol | I-UV-328 | 247-384-8 | 25973-55-1 | I-PBT i-vPvB |
| 52 | 2,4-di-tert-butyl6-(5-chlorobenzotriazol2-yl) phenol | I-UV-327 | 223-383-8 | 3864-99-1 | i-vPvB |
| 53 | 2-(2H-benzotriazol-2-yl)-4-(tert-butyl)-6-(sec-butyl) phenol | I-UV-350 | 253-037-1 | 36437-37-3 | i-vPvB |
| 54 | 2-benzotriazol-2-yl-4,6-di-tertbutylphenol | I-UV-320 | 223-346-6 | 3846-71-7 | I-PBT i-vPvB |
Ngokusekelwe ebufakazini obutholakalayo, i-ECHA icabanga ukukhawulela noma ukwenqabela ukusetshenziswa (noma ukuba khona) kwezinto ezintathu kwezine, okuhlanganisa i-UV-320, UV-350, ne-UV-327 kuma-athikili kanye nokulungiselela idosi le-Annex XV ukuze libe nomkhawulo ngezizathu ezilandelayo:
- I-UV-320, UV-327, ne-UV-350 yizinto ze-vPvB, noma i-vPvB kanye ne-PBT, futhi ibeka engcupheni imvelo engalawulwa ngokwanele.
- Umkhawulo ongaphansi lapho ukuchayeka okungavikeleka khona awukwazi ukunqunywa; futhi
- I-UV-327, UV-350, kanye ne-UV-320 akuhlongozwanga ukuthi kubuyekezwe ngaphansi kweNgqungquthela yaseStockholm. Ngakho-ke, ubungozi babo ngeke kubhekwane nabo ngokomthetho we-EU POP.
Ngokuya nge-UV-328, i-ECHA inombono wokuthi okwamanje asikho isidingo sokulungiselela idosi le-Annex XV ukuze libe nomkhawulo njengoba into kulindeleke ukuthi isingathwe yi-EU POPs regulation.
Kuhle ukusho ukuthi yi-UV-328 kuphela ebhaliswe ngaphansi komthetho we-EU REACH ngevolumu yokungenisa eqinisekisiwe yonyaka cishe amathani ayi-1,000. I-Japan iphinde yakhipha umkhawulo osalungiswa ku-UV-328 ngoDisemba 2023 ukuze kuvikelwe impilo yomphakathi.
Izingozi
Ama-phenolic benzotriazoles amane asetshenziswa njengezimunyisi ze-UV zezinhlobonhlobo zamapulasitiki, irabha, izinhlaka, nezinye izinto eziphilayo. Lezi zinto azikwazi ukubola kalula noma ngokwemvelo ngakho-ke zithathwa njengeziphikelelayo. Angahlala emvelweni isikhathi eside futhi abe namandla aphezulu okuqongelela ku-biota. I-ECHA igqamise embikweni wayo wokuthi uma lezi zinto sezingenile endaweni ezungezile, ukuchayeka kuzo kunzima kakhulu ukuhlehlisa, noma ngabe ukukhishwa/ukukhishwa kwazo kuyekwa.
Finyelela Ukugunyazwa Nokuvinjelwa
Ngaphansi komthethonqubo we-EU REACH, ukugunyazwa kwe-REACH (ngaphansi kwe-Annex XIV) kanye nomkhawulo (ngaphansi kwe-Annex XVII) kusebenza kanyekanye ukuze kusungulwe iphrothokholi yokuphepha ebanzi.
- Ukugunyazwa izokhawulela ukusetshenziswa kwamakhemikhali athile ngokubeka izikhathi zokusetshenziswa kwesikhashana. Uma isikhathi sokusebenzisa sesikhashana sesiphelelwe yisikhathi, into ehambisanayo inqatshelwe ukuthi ithengiswe emakethe ye-EU.
- Imikhawulo wukulawula ukugcwala okuvunyelwe okuphezulu kwezinto ezithile emikhiqizweni noma ukukhawulela ukusetshenziswa kwazo ezinhlelweni ezithile ezithile.
Ngokuvamile, izinto ezikhawulelwe ngaphansi kwe-Annex XVII ngeke zifakwe ohlwini Lokugunyazwa ngaphansi kweSijobelelo XIV kanye kanye.
