Amerika izashyira mu bikorwa ibyangombwa bisabwa kugira ngo ibintu 329 PFAS bishoboke

Ku ya 27 Mutarama 2023, Ikigo cyo muri Amerika gishinzwe kurengera ibidukikije (EPA) cyasabye ko hashyirwa mu bikorwa itegeko rikomeye ry’imikoreshereze mishya (SNUR) ku bintu bidakora PFAS bidashyizwe ku rutonde hakurikijwe itegeko rigenga ibiyobyabwenge (TSCA).

Nyuma yumwaka umwe wo kuganira no kungurana ibitekerezo, iki cyemezo cyo kugenzura cyashyizwe mubikorwa kumugaragaro ku ya 8 Mutarama 2024!
1. Ibintu bidakora
Ibintu bidakora mububiko bwa TSCA bivuga ibintu bya shimi bitakozwe, bitumizwa mu mahanga, cyangwa bitunganijwe muri Amerika kuva ku ya 21 Kamena 2006.
Muri rusange, imiti nkiyi ntisaba isuzumabumenyi ryuzuye rya EPA no gukemura ibibazo kugirango isubukure ibikorwa byubucuruzi, ibicuruzwa bitumizwa mu mahanga, nogutunganya ibicuruzwa muri Amerika.
Hamwe nogushiraho politiki yanyuma yo kugenzura, inzira yo kongera umusaruro wibintu bya PFAS idakora muri Amerika bizahinduka.
2. Amavu n'amavuko y'ingamba zatangijwe
EPA ibona ko niba ibintu bya PFAS bidakora byemerewe kongera umusaruro nibindi bikorwa hatabanje gusuzumwa neza no gukemura ibibazo, byanze bikunze byangiza ubuzima bwabantu n’ibidukikije.

Kubera iyo mpamvu, EPA yemeje ko ibintu nkibi bigomba gukorerwa Itangazo Rikoreshwa Rishya (SNUN) mbere yo kongera umusaruro nibindi bikorwa. Uwatanze imenyekanisha agomba gutanga amakuru ku mikoreshereze, imurikwa, no kurekurwa muri Amerika muri EPA kugira ngo asuzumwe, kandi amenye niba bizatera ingaruka zitagengwa n’ubuzima bw’abantu n’ibidukikije mbere yo kubikoresha.
3. Nibihe bintu bizahura ningamba zo kugenzura
Iyi politiki yo kugenzura ikubiyemo ibintu 329 bidakora PFAS.
Ibintu 299 byashyizwe kurutonde, kandi ibigo birashobora kubyemeza binyuze mumakuru nka numero CAS. Ariko haracyari ibintu 30 bitashyizwe kurutonde neza kubera uruhare rwabo mubisabwa na ସିବିଆଇ. Niba ibikoresho byikigo byujuje ibisobanuro bikurikira bya PFAS, birakenewe kohereza ibyemezo bishya kuri EPA:
R - (CF2) - CF (R ') R', aho CF2 na CF byombi byuzuye karubone;
R-CF2OCF2-R ', aho R na R' bishobora kuba F, O, cyangwa karubone yuzuye;
CF3C (CF3) R'R '', aho R 'na R' 'bishobora kuba F cyangwa karubone yuzuye.
Laboratwari ya BTF ni ikigo cyipimisha cyemewe n’ikigo cy’igihugu cy’Ubushinwa gishinzwe kwemeza ibipimo ngenderwaho (CNAS), nimero: L17568. Nyuma yimyaka yiterambere, BTF ifite laboratoire ihuza amashanyarazi, laboratoire itumanaho idafite umugozi, laboratoire ya SAR, laboratoire yumutekano, laboratoire yizewe, laboratoire yo gupima batiri, gupima imiti nizindi laboratoire. Ifite amashanyarazi meza, guhuza radio, umutekano wibicuruzwa, kwizerwa kubidukikije, gusesengura ibintu, ROHS / REACH nubundi bushobozi bwo gupima. 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.
