PFHxA izashyirwa mubikorwa byo kugenzura REACH

Ku ya 29 Gashyantare 2024, Komite y’Uburayi ishinzwe kwiyandikisha, gusuzuma, gutanga uruhushya no kugabanya imiti (SHAKA) yatoye kwemeza icyifuzo cyo kugabanya aside ya paruforohexanoic (PFHxA), imyunyu yayo, nibindi bintu bifitanye isano n’umugereka wa XVII w’amabwiriza ya REACH.
1. Kubireba PFHxA, imyunyu, nibintu bifitanye isano
1.1 Amakuru y'ibikoresho
Acide Perfluorohexanoic (PFHxA) n'umunyu wacyo hamwe nibindi bifitanye isano na:
Imvange hamwe na parfluoroapentyl matsinda ahujwe na atome ya C5F11 igororotse cyangwa ishami
Kugira amatsinda agororotse cyangwa amashami C6F13 parfluorohexyl
1.2Kuyemo ibintu bikurikira:
C6F14
C6F13-C (= O) OH, C6F13-C (= O) OX ′ cyangwa C6F13-CF2-X ′ (aho X ′ = itsinda iryo ari ryo ryose rikora, harimo umunyu)
Ikintu cyose gifite parfluoroalkyl C6F13- ihujwe neza na atome ya sulfuru
1.3Ibisabwa
Mu bikoresho bimwe:
PFHxA n'umunyu wacyo: ＜ 0,025 mg / kg
Ibintu byose bifitanye isano na PFHxA: mg 1 mg / kg
2. Igenzura
Kurwanya inkongi y'umuriro hamwe no kurwanya inkongi y'umuriro byibanda ku kurwanya umuriro rusange, imyitozo no kwipimisha: amezi 18 nyuma y'amabwiriza atangiye gukurikizwa.
Kubikoresha rusange: imyenda, uruhu, ubwoya, inkweto, imvange yimyenda nibikoresho bifitanye isano; Amavuta yo kwisiga; Impapuro zo guhuza ibiryo n'ikarito: amezi 24 uhereye igihe amabwiriza yatangiriye gukurikizwa.
Imyenda, uruhu, nubwoya mubicuruzwa bitari imyenda nibindi bikoresho bifitanye isano kugirango bikoreshwe rusange: amezi 36 uhereye igihe amabwiriza yatangiriye gukurikizwa.
Indege za gisivili zirwanya ifuro hamwe no kurwanya ifuro yibanda: amezi 60 nyuma yamabwiriza atangiye gukurikizwa.
PFHxAs ni ubwoko bwimvange ya polyfluoroalkyl (PFAS). Ibintu bya PFHxA bifatwa nkibikomeza kandi bitemba. Zikoreshwa cyane mu nganda nyinshi, nk'impapuro n'impapuro (ibikoresho byo guhuza ibiryo), imyenda nk'ibikoresho byo kurinda umuntu ku giti cye, imyenda yo mu rugo n'imyambaro, hamwe n'ifuro y'umuriro. Umuryango w’ubumwe bw’ibihugu by’Uburayi w’iterambere ry’imiti ushyira politiki ya PFAS ku isonga no hagati. Komisiyo y’Uburayi yiyemeje gukuraho buhoro buhoro PFAS yose kandi yemerera gusa kuyikoresha mu bihe byagaragaye ko idasimburwa kandi ifite akamaro muri sosiyete.
Laboratwari ya BTF ifite ibikoresho byumwuga kandi byuzuye, itsinda ryinzobere mu gupima no gutanga impamyabumenyi, hamwe nubushobozi bwo gukemura ibibazo bitandukanye byo gupima no gutanga ibyemezo. Twubahiriza amahame ngenderwaho y "" ubutabera, kutabogama, ubunyangamugayo, no gukomera "kandi dukurikiza byimazeyo ibisabwa na sisitemu yo gucunga laboratoire ya ISO / IEC 17025 na kalibrasi yo gucunga ubumenyi. Twiyemeje guha abakiriya serivisi nziza. Niba ufite ikibazo, nyamuneka twandikire igihe icyo aricyo cyose.
