PFHxA idzaphatikizidwa mu REACH regulatory control

Pa February 29, 2024, European Committee on Registration, Evaluation, Licensing and Restriction of Chemicals.FIKIRANI) adavota kuti avomereze malingaliro oletsa perfluorohexanoic acid (PFHxA), mchere wake, ndi zinthu zina zomwe zili mu Appendix XVII ya lamulo la REACH.
1. Ponena za PFHxA, mchere wake, ndi zinthu zina
1.1 Zambiri zakuthupi
Perfluorohexanoic acid (PFHxA) ndi mchere wake ndi zinthu zina zokhudzana ndi izi:
Zophatikizika ndi magulu a perfluoroapentyl olumikizidwa ndi maatomu a kaboni a C5F11 owongoka kapena nthambi
Kukhala ndi magulu a C6F13 perfluorohexyl owongoka kapena nthambi
1.2 Kupatula zinthu zotsatirazi:
C6F14
C6F13-C (=O) OH, C6F13-C (=O) OX ′ kapena C6F13-CF2-X ′ (pomwe X ′=gulu lililonse logwira ntchito, kuphatikiza mchere)
Chilichonse chokhala ndi perfluoroalkyl C6F13- cholumikizidwa mwachindunji ndi maatomu a sulfure
1.3 Malire zofunika
Mu zinthu homogeneous:
PFHxA ndi kuchuluka kwake mchere: ＜ 0.025 mg/kg
Zonse zokhudzana ndi PFHxA: ＜ 1 mg/kg
2. Kuwongolera kuchuluka
Chithovu chozimitsa moto ndi thovu lozimitsa moto limayang'ana kwambiri zozimitsa moto pagulu, kuphunzitsa ndi kuyesa: miyezi 18 malamulowo atayamba kugwira ntchito.
Zogwiritsidwa ntchito pagulu: nsalu, zikopa, ubweya, nsapato, zosakaniza muzovala ndi zina zowonjezera; Zodzoladzola; Mapepala okhudzana ndi chakudya ndi makatoni: Miyezi 24 kuchokera tsiku logwira ntchito la malamulowo.
Zovala, zikopa, ndi ubweya muzinthu zina osati zovala ndi zina zogwiritsiridwa ntchito ndi anthu: Miyezi 36 kuchokera tsiku logwira ntchito la malamulowo.
Chithovu chozimitsa moto pa ndege ndi thovu lozimitsa moto: patatha miyezi 60 malamulowo atayamba kugwira ntchito.
PFHxAs ndi mtundu wa perfluorinated and polyfluoroalkyl compound (PFAS). Zinthu za PFHxA zimawonedwa kuti ndizolimbikira komanso zamadzimadzi. Amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, monga mapepala ndi mapepala (zothandizira chakudya), nsalu monga zida zodzitetezera, nsalu zapakhomo ndi zovala, ndi thovu lamoto. Dongosolo lokhazikika la EU lachitukuko chamankhwala limayika mfundo za PFAS patsogolo komanso pakati. European Commission yadzipereka kuthetsa pang'onopang'ono PFAS yonse ndikungolola kuti igwiritsidwe ntchito m'malo omwe zitsimikiziridwa kuti ndizosasinthika komanso zofunika kwambiri kwa anthu.
BTF Testing Lab ili ndi malo oyezera akatswiri komanso athunthu, gulu lazoyeserera ndi akatswiri a certification, komanso kuthekera kothana ndi zovuta zosiyanasiyana zoyesa ndi ziphaso. Timatsatira mfundo zotsogola za "chilungamo, kusakondera, kulondola, ndi kukhwima" ndikutsata mosamalitsa zofunikira za ISO/IEC 17025 test and calibration laboratory management system for science management. Tadzipereka kupatsa makasitomala ntchito zabwino kwambiri. Ngati muli ndi mafunso, chonde omasuka kulankhula nafe nthawi iliyonse.
