TPCH ku United States imatulutsa malangizo a PFAS ndi Phthalates

Mu Novembala 2023, lamulo la US TPCH lidapereka chikalata chowongolera pa PFAS ndi Phthalates pamapaketi. Chikalata chowongolerachi chimapereka malingaliro pa njira zoyezera mankhwala omwe amatsatira kuyika zinthu zapoizoni.

Mu 2021, malamulo aphatikiza PFAS ndi Phthalates omwe akuwongolera ndikuletsa kugwiritsa ntchito mwadala pakuyika ndi mayendedwe ake. Panthawiyi, dziko lililonse lasintha malamulo omwe alipo kale kapena kukhazikitsa malamulo ndi malamulo atsopano kuti aletse zinthu zapoizoni ndi zovulaza m'mapaketi. Posachedwapa, mayiko ambiri aletsa kugwiritsa ntchito zinthu za PFAS ponyamula zakudya.
Chikalata chowongolerachi chimapereka njira zoyeserera zoyeserera za PFAS, monga fluoride yonse. Ngati zonse za fluorine zili pansi pa 100ppm ndipo zikugwirizana ndi miyezo yoyendetsera bwino, chinthucho chikhoza kuganiziridwa ngati sichikuwonjezera mwadala zinthu za PFAS. Ngati kuchuluka kwa fluorine kuli kochepa kwambiri (monga pansi pa 100ppm), kutsimikizira kwina kungapangidwe ndi wogulitsa. Chikalata chowongolera chikugogomezera kuti kuwonekera poyera ndikofunikira pakutsatiridwa, ndipo tikulimbikitsidwa kugwiritsa ntchito dongosolo ili kutsimikizira ngati PFAS ikufuna kuwonjezera:
1) Funsani ogulitsa kuti afotokozere zonse;
Amafuna ogulitsa kuti apereke chidziwitso chokwanira;
2) Funsani ogulitsa kuti atseke ngati mankhwala a PFAS awonjezedwa;
Amafuna ogulitsa kuti aulule ngati zinthu za PFAS zawonjezedwa;
3) Yang'anani chiphaso chachitatu cha zida zanu
Mukuyang'ana chiphaso chachitatu.
TPCH ikuwonetsa kugwiritsa ntchito SW 846 njira 8270 pokonzekera zitsanzo ndi njira ya EPA 3541 pakuyesa kuyika zinthu zokhudzana ndi njira yoyesera ya Phthalates. Nawa mndandanda wa ma phthalates omwe nthawi zambiri amawunikidwa ndi njira zoyesera pamwambapa:

BTF Testing Lab ndi malo oyesera ovomerezeka ndi China National Accreditation Service for Conformity Assessment (CNAS), nambala: L17568. Pambuyo pakukula kwazaka zambiri, BTF ili ndi labotale yofananira ndi ma electromagnetic, labotale yolumikizirana opanda zingwe, labotale ya SAR, labotale yachitetezo, labotale yodalirika, labotale yoyezetsa ma batire, kuyezetsa mankhwala ndi ma labotale ena. Imayenderana bwino ndi ma elekitirodi, ma frequency a wailesi, chitetezo chazinthu, kudalirika kwa chilengedwe, kusanthula kulephera kwa zinthu, ROHS/REACH ndi kuyesa kwina. BTF Testing Lab ili ndi malo oyezera akatswiri komanso athunthu, gulu lazoyeserera ndi akatswiri a certification, komanso kuthekera kothana ndi zovuta zosiyanasiyana zoyesa ndi ziphaso. Timatsatira mfundo zotsogola za "chilungamo, kusakondera, kulondola, ndi kukhwima" ndikutsata mosamalitsa zofunikira za ISO/IEC 17025 test and calibration laboratory management system for science management. Tadzipereka kupatsa makasitomala ntchito zabwino kwambiri. Ngati muli ndi mafunso, chonde omasuka kulankhula nafe nthawi iliyonse.
