I-US FDA iphakamisa uvavanyo olunyanzelekileyo lwe-asbestos kwizinto zokuthambisa ezine-talc powder

Ngomhla wama-26 kuDisemba, ka-2024, i-US Food and Drug Administration (FDA) iphakamise isindululo esibalulekileyo esifuna abavelisi bezithambiso ukuba benze uvavanyo olunyanzelekileyo lwe-asbestos kwi-talc equlethe iimveliso ngokuhambelana nezibonelelo zoMthetho we-2022 we-Cosmetic Regulatory Modernization (MoCRA). Esi siphakamiso siya kuba neempembelelo ezinzulu kwishishini lezithambiso, ngakumbi kwimarike yomgubo we-talcum yomgangatho wokuthambisa.

Iindlela zokufumanisa ezicetywayo ze-FDA zibandakanya ikakhulu iindidi ezimbini: i-polarized light microscopy (PLM): le ndlela inokuhlalutya inani elikhulu leesampuli kunye nokuchonga i-asbestos ngokuqwalasela iimpawu ze-crystallographic optical (ezifana nombala, imibala emininzi, i-refractive index, i-birefringence, njl. ) kunye ne-particle morphology. Ukuhanjiswa kweMicroscopy ye-Electron / i-Energy Dispersive Spectroscopy / i-Selective Electron Diffraction (TEM / EDS / SAED): Le ndlela inokubona imicu encinci kwaye ibone i-asbestos ngokuhlalutya ukubunjwa kwe-elemental, i-crystal structure, kunye ne-particle morphology.

I-FDA ithe ukudibanisa ezi ndlela zimbini kunokunyusa ukubonwa kwe-asbestos. Nangona i-PLM inokunyusa okuphantsi, inokuhlalutya inani elikhulu leesampuli; Kwaye i-TEM/EDS/SAED inokubona iifiber ezincinci. Ezi ndlela zimbini ziyancedisana, ziphucula ukuchaneka kunye nobubanzi bokufumanisa.

Isindululo songqinelwano lwemigangatho yamazwe ngamazwe sihambelana nemigangatho yamazwe ngamazwe. I-European Union, iKhanada, kunye neJapan ziye zaseka imigaqo engqongqo efanayo ukuqinisekisa ukuba iimveliso zetalc aziqulathanga ungcoliseko lweasbestos. Ubuchwephesha beMicroscopic obufana ne-PLM kunye neTEM busetyenziswa ngokubanzi kwihlabathi liphela ukubona ngokuchanekileyo iasbestos. Lo mgangatho odibeneyo awuncedi kuphela ukukhusela impilo yabathengi, kodwa ukhuthaza urhwebo lwamazwe ngamazwe kunye nokwandisa ukuzithemba kwabathengi kukhuseleko lweemveliso ze-talc zehlabathi.

Isindululo se-FDA sichaza ngokucacileyo ukuba i-asbestos ifunyenwe kwizinto zokuthambisa okanye i-talc esetyenziswa kwizinto zokuthambisa, imveliso iya kuthathwa njengegqwethiweyo kwaye yaphule umthetho we-Federal Food, Drug, and Cosmetic Act. Lo mmiselo ubonelela ngesiseko esicacileyo esisemthethweni sokuthotyelwa komthetho.

Injongo ephambili yesi siphakamiso kukunciphisa umngcipheko wokuvezwa kwabathengi kwi-asbestos kunye nokukhusela izifo ezinxulumene nazo. Kwangaxeshanye, kuya kunceda abavelisi ukuba banciphise ukuphindaphindwa kweemveliso ezikhumbuzayo kunye nokunciphisa umngcipheko wokusebenza.

Ukongeza, esi siphakamiso sizalisa izikhewu kwizikhokelo ze-MoCRA, ngakumbi malunga nokungaqondwa ngokwaneleyo kwemigangatho yovavanyo lokhuseleko lwezithambiso ngamashishini amancinci naphakathi. I-FDA ngoku ichaze ngokucacileyo iindlela zokuvavanya i-asbestos kwi-talc, inika isikhokelo esicacileyo kwishishini.

I-FDA ivule ixesha lokuphononongwa koluntu lokuthatha inxaxheba koluntu kunye namanyathelo alandelayo, kunye nomhla wokugqibela we-27 Matshi 2025. Oku kunika ithuba loshishino kunye noluntu ukuba bathathe inxaxheba kwinkqubo yokulawula. Ukuba ekugqibeleni ipasisiwe, lo mmiselo mtsha uya kuphucula kakhulu ukhuseleko lwe-talc equlethe izithambiso kunye nokubonelela ngokhuseleko olunamandla kwimpilo yabathengi.

Isindululo se-FDA sibonisa ugxininiso oluphezulu lwabasemagunyeni kukhuseleko lwezithambiso, ngakumbi ekubhaqweni kwe-asbestos, i-carcinogen eyaziwayo. Ngokunikwa isindululo esitsha se-FDA, i-Bureau Veritas icebisa ukuba abavelisi bezithambiso baqale ukuvavanya nokuhlaziya iinkqubo zabo zolawulo lomgangatho kwangethuba, ngakumbi kwiimveliso eziqulethe i-talc. Amashishini afanelekileyo kufuneka afune uncedo kwangexesha kwii-arhente zovavanyo lomntu wesithathu, aqeqeshe abasebenzi abafanelekileyo, kwaye aseke inkqubo yolawulo lonikezelo olufanelekileyo ukuqinisekisa ukuthotyelwa kweemfuneko zolawulo olutsha, ukugcina isidima sohlobo, kunye nokuthenjwa kwabathengi.
