Hashyizweho itegeko ribuza dichloromethane gukoreshwa mu nganda, rigabanya ikoreshwa ryayo

Ku ya 30 Mata 2024, Ikigo gishinzwe kurengera ibidukikije muri Leta Zunze Ubumwe za Amerika (EPA) cyashyizeho itegeko ribuza ikoreshwa rya dichloromethane y’ibintu byinshi hakurikijwe amabwiriza agenga imicungire y’ibyago yo mu Itegeko rigenga uburozi (TSCA). Iki cyemezo kigamije kwemeza ko dichloromethane ikoreshwa mu buryo bugaragara ishobora gukoreshwa mu mutekano binyuze muri gahunda yuzuye yo kurengera abakozi. Iri tegeko rizatangira gukurikizwa mu minsi 60 nyuma y’uko rishyizwe mu gitabo cya Leta.

Dichloromethane ni imiti itera kanseri zitandukanye n'ibibazo bikomeye by'ubuzima, harimo kanseri y'umwijima, kanseri y'ibihaha, kanseri y'ibere, kanseri y'ubwonko, kanseri y'amaraso na kanseri y'imitsi yo hagati. Byongeye kandi, ifite ibyago byo kwangirika kw'ubwonko no kwangirika k'umwijima. Kubwibyo, iri tegeko risaba amasosiyete abishinzwe kugabanya buhoro buhoro umusaruro, gutunganya, no gukwirakwiza dichloromethane mu buryo bw'abaguzi n'inganda nyinshi n'ubucuruzi, harimo no gushariza inzu. Ikoreshwa ry'abaguzi rizavaho mu mwaka umwe, mu gihe ikoreshwa mu nganda n'ubucuruzi rizahagarikwa mu myaka ibiri.

Ku bintu bike bifite akamaro gakomeye mu nganda zikora cyane, iri tegeko ryemerera kugumana dichloromethane kandi rishyiraho uburyo bw'ingenzi bwo kurinda abakozi - Gahunda yo Kurinda Ibiyobyabwenge mu Kazi. Iyi gahunda ishyiraho imipaka ikomeye yo guhumeka, ibisabwa mu gukurikirana, n'inshingano zo guhugura abakozi no kumenyesha dichloromethane kugira ngo birinde abakozi ibyago byo kwandura kanseri n'ibindi bibazo by'ubuzima biterwa no guhura n'ibyo binyabutabire. Ku kazi kazakomeza gukoresha dichloromethane, ibigo byinshi bigomba kubahiriza amabwiriza mashya mu mezi 18 nyuma yo gusohora amategeko agenga imicungire y'ibyago no gukurikirana buri gihe.

Izi ngeri z'ingenzi zirimo:

Gukora ibindi binyabutabire, nk'ibinyabutabire by'ingenzi bikonjesha bishobora gukuraho buhoro buhoro hydrofluorocarbons zangiza nk'uko biteganywa n'Itegeko ry'Ubuhanga n'Ingufu by'Abanyamerika Bipartisan;

Gukora ibikoresho bitandukanya batiri z'imodoka bikoresha amashanyarazi;

Ibifasha mu gutunganya ibikoresho muri sisitemu zifunze;

Gukoresha imiti yo muri laboratwari;

Gukora pulasitiki na kabutura, harimo no gukora polycarbonate;

Gusudira ibikoresho bishongesha.
