Ikigo cyo muri Amerika gishinzwe kurengera ibidukikije cyasohoye ku mugaragaro amategeko yanyuma ya raporo ya PFAS

Ku ya 28 Nzeri 2023, Ikigo cyo muri Amerika gishinzwe kurengera ibidukikije (EPA) cyasohoye itegeko ryo gutanga raporo ya PFAS, ryateguwe n'abayobozi ba Amerika mu gihe kirenze imyaka ibiri kugira ngo riteze imbere gahunda y'ibikorwa byo kurwanya umwanda wa PFAS, kurengera ubuzima rusange, no guteza imbere ubutabera bushingiye ku bidukikije. Nibikorwa byingenzi mubishushanyo mbonera bya EPA kuri PFAS, Muri kiriya gihe, ububiko bunini cyane bwibintu bya perfluoroalkyl na perfluoroalkyl (PFAS) byakozwe kandi bikoreshwa muri Amerika bizahabwa EPA, abafatanyabikorwa bayo, ndetse n’abaturage.

Ibirimo byihariye
Ikigo cyo muri Amerika gishinzwe kurengera ibidukikije (EPA) cyasohoye amategeko ya nyuma yo gutanga raporo no kubika inyandiko ku bintu bya perfluoroalkyl na perfluoroalkyl (PFAS) hakurikijwe ingingo ya 8 (a) (7) y’itegeko rigenga ibiyobyabwenge (TSCA). Iri tegeko risaba ko abakora cyangwa abatumiza mu mahanga PFAS cyangwa PFAS ikubiyemo ibintu byakozwe (harimo n’ibitumizwa mu mahanga) mu mwaka uwo ari wo wose kuva mu mwaka wa 2011 bagomba guha EPA amakuru ku mikoreshereze yabo, umusaruro, kujugunywa, guhura n’ibyago bitarenze amezi 18-24 nyuma y’iri tegeko ritangiye gukurikizwa. , kandi inyandiko zibishinzwe zigomba kubikwa mumyaka 5. Ibintu bya PFAS bikoreshwa nk'imiti yica udukoko, ibiryo, inyongeramusaruro, ibiyobyabwenge, amavuta yo kwisiga, cyangwa ibikoresho byubuvuzi birasonerwa iyi nshingano yo gutanga raporo.

1 Ubwoko bwa PFAS burimo
Ibintu bya PFAS nicyiciro cyibintu bya shimi bifite ibisobanuro byihariye byubatswe. Nubwo EPA itanga urutonde rwibintu bya PFAS bisaba inshingano zo kumenyesha, urutonde ntabwo rwuzuye, bivuze ko amategeko atarimo urutonde rwihariye rwibintu byagaragaye. Ahubwo, itanga gusa ibice byujuje ibyaribyo byose bikurikira, bisaba inshingano za raporo za PFAS:
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.

2 Kwirinda
Dukurikije ingingo ya 15 n'iya 16 z'Itegeko ryo muri Amerika rishinzwe kurwanya ibiyobyabwenge (TSCA), kudatanga amakuru hakurikijwe ibisabwa n'amategeko bizafatwa nk'igikorwa kinyuranyije n'amategeko, bihanishwa ibihano by'abaturage, kandi bishobora gukurikiranwa mu nkiko.
BTF ivuga ko ibigo byakoranye n’ubucuruzi n’ubucuruzi n’Amerika kuva mu mwaka wa 2011 bigomba gushakisha byimazeyo inyandiko z’ubucuruzi z’imiti cyangwa ibintu, ikemeza niba ibicuruzwa birimo ibintu bya PFAS byujuje ibisobanuro by’imiterere, kandi bikuzuza igihe inshingano zabo zo gutanga raporo kugira ngo birinde ingaruka zo kubahiriza.
BTF iributsa ibigo bireba gukurikiranira hafi uko ivugururwa ry’amabwiriza ya PFAS, no gutegura umusaruro no guhanga ibintu mu buryo bushyize mu gaciro kugira ngo ibicuruzwa byubahirizwe. Dufite itsinda ryabahanga babigize umwuga kugirango bakurikirane iterambere rigezweho mubipimo ngenderwaho kandi bagufashe mugutegura gahunda iboneye. Nyamuneka nyamuneka twandikire.
