Kubuza dichloromethane yatangijwe, irekuwe kubuza gukoresha inganda

Ku ya 30 Mata 2024, Ikigo cyo muri Amerika gishinzwe kurengera ibidukikije (EPA) cyabujije ikoreshwa rya dichloromethane ifite intego nyinshi hakurikijwe amabwiriza yo gucunga ingaruka z’itegeko rigenga ibiyobyabwenge (TSCA). Uku kwimuka kugamije kwemeza ko gukoresha dichloromethane bishobora gukoreshwa neza binyuze muri gahunda yuzuye yo kurengera abakozi. Iri tegeko rizatangira gukurikizwa mu minsi 60 nyuma yo gutangazwa muri rejisitiri nkuru.

Dichloromethane ni imiti iteje akaga, ishobora gutera kanseri zitandukanye n’ibibazo bikomeye by’ubuzima, harimo kanseri y’umwijima, kanseri y'ibihaha, kanseri y'ibere, kanseri y'ubwonko, leukemia na kanseri yo hagati yo hagati. Byongeye kandi, itwara kandi ibyago byo kwangirika kwa neurotoxicity no kwangirika kwumwijima. Kubwibyo, kubuza bisaba ibigo bireba kugabanya buhoro buhoro umusaruro, gutunganya, no gukwirakwiza dichloromethane kubaguzi nibikorwa byinshi byinganda nubucuruzi, harimo no gushariza amazu. Imikoreshereze y’abaguzi izavaho mu gihe cyumwaka umwe, mu gihe inganda n’ubucuruzi bizabuzwa mu myaka ibiri.

Kubintu bike bifite akamaro gakomeye mubidukikije byateye imbere cyane, iri tegeko ryemerera kugumana dichloromethane kandi rishyiraho uburyo bwingenzi bwo kurinda abakozi - Gahunda yo Kurinda Imiti Yumurimo. Iyi gahunda ishyiraho imipaka igaragara, ibisabwa byo gukurikirana, n'amahugurwa y'abakozi n'inshingano zo kumenyesha dichloromethane kurinda abakozi ibyago bya kanseri nibindi bibazo byubuzima biterwa no guhura niyi miti. Ku kazi kazakomeza gukoresha dichloromethane, umubare munini wibigo bigomba kubahiriza amabwiriza mashya mugihe cyamezi 18 nyuma yisohoka ryamategeko agenga imicungire y’ibyago kandi bigakurikiranwa buri gihe.

Izi ngingo zingenzi zikoreshwa zirimo:

Gukora indi miti, nkimiti yingenzi ya firigo ishobora gukuraho buhoro buhoro hydrofluorocarbone yangiza amategeko ya Bipartisan American Innovation and Manufacturing Act;

Gukora ibinyabiziga bitandukanya amashanyarazi;

Imfashanyo yo gutunganya muri sisitemu ifunze;

Gukoresha imiti ya laboratoire;

Gukora plastiki na reberi, harimo no gukora polyakarubone;

Gusudira.
