Inqubekelaphambili yakamuva emikhawulweni ye-EU PFAS

Ngomhla zingama-20 kuNovemba 2024, iziphathimandla zase-Denmark, Germany, Netherlands, Norway, nase-Sweden (abahambisa amafayela) kanye ne-ECHA's Risk Assessment Scientific Committee (RAC) kanye ne-Socio Economic Analysis Scientific Committee (SEAC) zacubungula ngokugcwele imibono yesayensi nezobuchwepheshe engaphezu kuka-5600. etholwe ezinkampanini zangaphandle ngesikhathi sokubonisana ngo-2023, futhi yakhipha inqubekelaphambili yakamuva ngenqubo yokukhawulela i-perfluoroalkyl ne-polyfluoroalkyl izinto (PFAS) eYurophu.

Le mibono yokubonisana engaphezu kuka-5600 idinga othumele ifayela ukuthi aqhubeke ecubungula, abuyekeze, futhi athuthukise ulwazi lokuvinjelwa oluhlongozwayo njengamanje ku-PFAS. Kuphinde kwasiza ekuhlonzeni ukusetshenziswa okungazange kukhulunywe ngokuqondile esiphakamisweni sokuqala, ezifakwe ekuhlolweni okukhona komnyango noma okuhlukaniswa njengeminyango emisha njengoba kudingeka:

Izicelo zokubeka uphawu (ama-polymers ane-fluorinated asetshenziswa kakhulu kubathengi, izimboni, nezimboni, okuhlanganisa izimpawu, amapayipi amapayipi, ama-gaskets, izingxenye ze-valve, njll.);

Izindwangu zobuchwepheshe (i-PFAS esetshenziswa kumafilimu asebenza kahle kakhulu, izinto zezokwelapha ezingamboziwe izinhlelo zezokwelapha, izindwangu zobuchwepheshe zangaphandle njengezindwangu ezingangeni manzi, njll.);

Izicelo zokuphrinta (izingxenye ezihlala njalo nezinto ezisetshenziswayo zokuphrinta);

Ezinye izinhlelo zokusebenza zezokwelapha, ezifana nokupakishwa nezinto ezisizayo zezidakamizwa.

Ngaphezu kokuvinjelwa okuphelele noma ukuvinjelwa kwesikhathi esinqunyelwe, i-ECHA iphinde icabangele ezinye izinketho zokukhawulela. Isibonelo, enye inketho ingase ibandakanye izimo ezivumela i-PFAS ukuthi iqhubeke nokukhiqiza, ukumaketha noma ukusetshenziswa, kunokuvinjelwa (izinketho zokukhawulela ngaphandle kokuvinjelwa). Lokhu kucatshangelwa kubaluleke kakhulu ebufakazini obubonisa ukuthi ukuvinjelwa kungase kubangele imithelela engalingani kwezenhlalo-mnotho. Izinjongo zalezi ezinye izinketho ezicatshangelwayo zihlanganisa kodwa azikhawulelwe kulokhu:

Ibhethri;

I-Fuel cell;

Electrolytic cell.

Ngaphezu kwalokho, ama-fluoropolymers ayisibonelo seqembu lezinto ezine-perfluorinated ezikhathazeke kakhulu ngababambe iqhaza. Lokhu kuxoxisana kuphinde kwajulisa ukuqonda ngokutholakala kwezinye izindlela zokusetshenziswa okuthile kwalawa ma-polymer, izinyathelo zobuchwepheshe nezenhlangano zokunciphisa ukukhishwa kwazo endaweni ezungezile, kanye nemithelela engase ibe khona kwezenhlalo-mnotho yokuvinjelwa kokukhiqizwa kwawo, ukukhishwa kwemakethe, kanye nokusetshenziswa kwawo kudingeka kucatshangelwe kabusha.

I-ECHA izohlola ibhalansi yenye indlela ngayinye futhi iyiqhathanise nezinketho ezimbili zokuqala zemikhawulo, okuwukuthi ukuvinjelwa okuphelele noma ukuvinjelwa kokukhululwa okunomkhawulo wesikhathi. Yonke le mininingwane ebuyekeziwe izohlinzekwa kumakomidi e-RAC kanye ne-SEAC ukuze kuqhutshekwe nokuhlolwa kwesiphakamiso. Ukuthuthukiswa kwemibono kuzothuthukiswa futhi ngo-2025 futhi kuzokhiqiza imibono esalungiswa evela ku-RAC kanye ne-SEAC. Ngemva kwalokho, kuzobanjwa izingxoxo mayelana nemibono ewuhlaka yekomidi labaluleki. Lokhu kuzonikeza ithuba kubo bonke abantu besithathu abanentshisekelo yokuhlinzeka ngolwazi olufanele lwezenhlalo nezomnotho ukuze kucutshungulwe umbono wokugcina we-SEAC.
