United States ichaita zvimwe zviziviso zvinodiwa zve329 PFAS zvinhu

Musi waNdira 27, 2023, iyo US Environmental Protection Agency (EPA) yakakurudzira kuitwa kweYakakosha New Use Rule (SNUR) yezvinhu zvisingashande zvePFAS zvakanyorwa pasi peToxic Substances Control Act (TSCA).

Mushure merinenge gore rekukurukurirana nekufunga, iyi nhanho yekudzora yakazoitwa zviri pamutemo muna Ndira 8, 2024!
1. Zvinhu zvisingashande
Izvo zvisingashande zviri muTSCA dhairekitori zvinoreva zvinhu zvemakemikari zvisina kugadzirwa, kutengwa kunze kwenyika, kana kugadziriswa muUnited States kubva munaChikumi 21, 2006.
Kazhinji, makemikari akadaro haadi yakakwana EPA ongororo uye kugadzirisa njodzi kuti utangezve kugadzira, kupinza, uye kugadzirisa zviitiko zvekutengeserana mukati meUnited States.
Nekuunzwa kweazvino marongero ekutonga, maitiro ekutangazve kugadzirwa kwezvinhu zvisingashande zvePFAS mukati meUnited States achachinja.
2. Nheyo yematanho akaunzwa
Iyo EPA inoona kuti kana isingashande PFAS zvinhu zvikatenderwa kutangazve kugadzira uye zvimwe zviitiko pasina ongororo yakakwana uye kugadzirisa njodzi, zvinozokonzera kukuvadza kuhutano hwevanhu uye nharaunda.

Naizvozvo, EPA yafunga kuti zvinhu zvakadaro zvinofanirwa kupinda Chirevo Chitsva Chekushandisa Chiziviso (SNUN) chisati chatangazve kugadzira nezvimwe zviitiko. Declarant inofanirwa kuendesa ruzivo rwekushandisa kwavo, kufumurwa, uye kuburitswa mukati meUnited States kuEPA kuti iongororwe, uye kuona kana vachizoisa njodzi dzisingadzoreki kuhutano hwevanhu uye nharaunda isati yashandiswa.
3. Ndezvipi zvinhu zvichatarisana nematanho ekudzora
Iyi yekudzora mutemo inosanganisira 329 isingashande PFAS zvinhu.
299 zvinhu zvakanyorwa pane iyo rondedzero, uye makambani anogona kuzvisimbisa kuburikidza neruzivo senge nhamba dzeCAS. Asi kuchine zvinhu makumi matatu zvisina kunyorwa zvakajeka nekuda kwekubatanidzwa kwavo muCBI application. Kana izvo zvebhizinesi zvichisangana neanotevera PFAS chimiro tsananguro, zvinodikanwa kuendesa humbowo cheki cheki kuEPA:
R - (CF2) - CF (R ') R', apo zvose CF2 neCF zvakasvibiswa kabhoni;
R-CF2OCF2-R ', apo R uye R' inogona kuva F, O, kana saturated carbon;
CF3C (CF3) R'R '', apo R 'uye R' 'inogona kuva F kana kuti saturated carbon.
BTF Testing Lab inzvimbo yekuyedza yakatenderwa neChina National Accreditation Service yeConformity Assessment (CNAS), nhamba: L17568. Mushure memakore ebudiriro, BTF ine electromagnetic inoenderana murabhoritari, isina waya yekutaurirana murabhoritari, SAR rabhoritari, kuchengetedza marabhoritari, kuvimbika marabhoritari, marabhoritari yekuyedza bhatiri, kuongororwa kwemakemikari uye mamwe marabhoritari. Iine yakakwana electromagnetic inoenderana, redhiyo frequency, kuchengetedzwa kwechigadzirwa, kuvimbika kwezvakatipoteredza, kuongororwa kutadza kwezvinhu, ROHS / REACH uye humwe hunyanzvi hwekuyedza. BTF Testing Lab yakashongedzerwa nehunyanzvi uye yakakwana yekuyedza zvivakwa, timu ine ruzivo yekuyedza uye nyanzvi dzezvitupa, uye kugona kugadzirisa kwakasiyana kwakaoma kuyedzwa uye matambudziko etifiketi. Isu tinoomerera kune inotungamira misimboti ye "kurongeka, kusarerekera, kurongeka, uye kuomarara" uye tinonyatso kutevedzera zvinodiwa ne ISO/IEC 17025 yekuyedza uye calibration laboratory manejimendi system yekutonga kwesainzi. Takazvipira kupa vatengi basa remhando yepamusoro. Kana uine mibvunzo, ndapota inzwa wakasununguka kutibata nesu chero nguva.
