Thaum Lub Ib Hlis 27, 2023, US Environmental Protection Agency (EPA) tau tshaj tawm txoj kev siv Txoj Cai Siv Tshiab Tseem Ceeb (SNUR) rau cov tshuaj PFAS uas tsis muaj npe nyob rau hauv Txoj Cai Tswj Tshuaj Toxic (TSCA).
Tom qab ze li ib xyoos ntawm kev sib tham thiab kev txiav txim siab, qhov kev tswj xyuas no thaum kawg tau ua tiav thaum Lub Ib Hlis 8, 2024!
1. Cov tshuaj tsis ua haujlwm
Cov tshuaj tsis muaj zog hauv TSCA phau ntawv qhia yog hais txog cov tshuaj uas tsis tau tsim, xa tawm, lossis ua tiav hauv Tebchaws Meskas txij thaum Lub Rau Hli 21, 2006.
Feem ntau, cov tshuaj no tsis tas yuav tsum tau ua tiav EPA kev ntsuam xyuas thiab kev daws teeb meem kev pheej hmoo kom rov pib tsim khoom, ntshuam, thiab kev ua lag luam hauv Tebchaws Meskas.
Nrog rau kev qhia txog cov cai tswj xyuas tshiab kawg, cov txheej txheem rau rov pib tsim cov tshuaj PFAS tsis ua haujlwm hauv Tebchaws Meskas yuav raug hloov pauv.
2. Keeb kwm ntawm kev ntsuas tau qhia
EPA tau txiav txim siab tias yog tias cov tshuaj PFAS tsis ua haujlwm raug tso cai rov pib tsim khoom thiab lwm yam dej num yam tsis muaj kev ntsuam xyuas tiav thiab kev daws teeb meem, nws yuav ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig.
Yog li ntawd, EPA tau txiav txim siab tias cov tshuaj no yuav tsum tau ua raws li Daim Ntawv Ceeb Toom Tshiab Siv Tseem Ceeb (SNUN) ua ntej rov pib tsim khoom thiab lwm yam dej num. Tus tshaj tawm yuav tsum xa cov ntaub ntawv ntawm lawv cov kev siv, raug, thiab tso tawm hauv Tebchaws Meskas mus rau EPA rau kev ntsuam xyuas, thiab txiav txim siab seb lawv puas yuav tsim kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig ua ntej siv.
3. Yam tshuaj twg yuav ntsib kev tswj xyuas
Txoj cai tswjfwm no suav nrog 329 yam tsis muaj zog PFAS.
299 yam khoom tau teev tseg hauv daim ntawv teev npe, thiab cov tuam txhab tuaj yeem lees paub lawv los ntawm cov ntaub ntawv xws li CAS tus lej. Tab sis tseem muaj 30 yam khoom uas tsis tau teev meej meej vim lawv txoj kev koom tes hauv CBI daim ntawv thov. Yog tias cov khoom ntawm lub tuam txhab ua tau raws li cov qauv hauv qab no PFAS cov ntsiab lus, nws yog ib qho tsim nyog yuav tsum xa daim ntawv lees paub tshiab rau EPA:
R - (CF2) - CF (R ') R', qhov twg CF2 thiab CF yog saturated carbon;
R-CF2OCF2-R ', qhov twg R thiab R' tuaj yeem yog F, O, lossis saturated carbon;
CF3C (CF3) R'R', qhov twg R' thiab R'' tuaj yeem yog F lossis saturated carbon.
BTF Testing Lab yog lub chaw kuaj xyuas tau lees paub los ntawm Tuam Tshoj National Accreditation Service for Conformity Assessment (CNAS), tus lej: L17568. Tom qab xyoo ntawm txoj kev loj hlob, BTF muaj electromagnetic compatibility laboratory, wireless kev sib txuas lus laboratory, SAR laboratory, kev soj ntsuam kev nyab xeeb, kev cia siab rau lub chaw soj nstuam, roj teeb kuaj kuaj, tshuaj ntsuam xyuas thiab lwm yam chaw soj nstuam. Nws muaj qhov zoo tshaj plaws electromagnetic compatibility, xov tooj cua zaus, cov khoom muaj kev ruaj ntseg, ib puag ncig kev ntseeg siab, cov ntaub ntawv tsis ua hauj lwm tsom xam, ROHS / REACH thiab lwm yam kev kuaj muaj peev xwm. BTF Testing Lab yog nruab nrog cov kws tshaj lij thiab ua tiav cov chaw sim, pab pawg paub txog kev sim thiab cov kws tshaj lij, thiab muaj peev xwm los daws ntau yam teeb meem kev sim thiab ntawv pov thawj. Peb ua raws li cov qauv qhia ntawm "kev ncaj ncees, kev ncaj ncees, kev ncaj ncees, thiab kev nruj" thiab ua raws li cov cai ntawm ISO/IEC 17025 kev ntsuam xyuas thiab ntsuas qhov ntsuas qhov ntsuas rau kev tswj xyuas kev tshawb fawb. Peb tau cog lus los muab cov neeg siv khoom nrog cov kev pabcuam zoo tshaj plaws. Yog tias koj muaj lus nug, thov koj xav tiv tauj peb txhua lub sijhawm.
