Kuletsa Dichloromethane, kumasulidwa kwa mafakitale

Pa Epulo 30, 2024, bungwe loteteza zachilengedwe ku United States (EPA) limaletsa kugwiritsa ntchito cholinga cha zinthu zambiri. Kusunthaku kumafuna kuonetsetsa kuti kugwiritsa ntchito motsutsa ku Dichloromethane kumatha kugwiritsidwa ntchito bwino kudzera mu pulogalamu yoteteza bwino. Kuletsedwa kumachitika mkati mwa masiku 60 pambuyo pofalitsa magazini atalembetsa ku Federal.

Dichlororthane ndi mankhwala oopsa, omwe angapangitse khansa yayikulu yazathanzi, kuphatikiza khansa ya chiwindi, khansa ya musunga, leukemia ndi chapakati mantha khansa. Kuphatikiza apo, imakhalanso ndi chiopsezo cha neurotoxicity ndi chiwindi. Chifukwa chake, kuleka kumafunikira makampani oyenera kuti muchepetse kupanga, kukonza, ndikugawa kwa DIVlorthamene kwa ogula ndi mafakitale ambiri komanso malonda, kuphatikiza zokongoletsa zapakhomo. Kugwiritsa ntchito kwa ogula kudzatulutsidwa mkati mwa chaka chimodzi, pomwe kugwiritsa ntchito mafakitale komanso malonda kudzawaletsedwa pasanathe zaka ziwiri.

Kwa zochitika zingapo zogwiritsa ntchito zofunika kwambiri m'malo okwanira, zoletsa izi zimalola kusungirako dichloromethane ndikukhazikitsa njira yoteteza makina ogwiritsira ntchito mankhwala. Makonzedwe awa amapereka malire okhwima, owunikira zofunikira za dichloronorthane kuti ateteze antchito ku chiwopsezo cha khansa ndi mavuto ena azaumoyo chifukwa cha kuwopsezedwa ndi mankhwala otere. Kwa malo antchito omwe apitilizabe kugwiritsa ntchito dichloromethane, makampani ambiri amafunika kutsatira malamulo atsopano patatha miyezi 18 atatulutsidwa kwa malamulo ndi chikhalidwe chowunikira pafupipafupi.

Izi zimaphatikizapo:

Kupanga mankhwala ena, monga mankhwala ofunikira kukhazikitsa ma hydrofluorbocarbons oopsa pansi pa a Bipartisan American Americanyame ku Frarce;

Kupanga magetsi olekanitsidwa;

Kukonza Edzi mu kachitidwe kotsekedwa;

Kugwiritsa ntchito mankhwala a labotale;

Kupanga pulasitiki ndi mphira, kuphatikizapo kupanga kwa polycarbonate;

Kuweta.
