Kubuza dichloromethane watangijwe, hagamijwe kurekura inganda zo gukoresha inganda

Ku ya 30 Mata 2024, ikigo gishinzwe kugenzura ibidukikije cya Amerika (EPA) cyasohoye kubera gukoresha imigambi myinshi dichloromethane hakurikijwe amabwiriza yo gucunga ibyago by'itegeko rishinzwe kurwanya uburozi (TSCA). Iyi moteri igamije kwemeza ko gukoresha dichloromethane bishobora gukoreshwa neza binyuze muri gahunda yo kurengera umutekano. Iri tegeko rizatangira gukurikizwa mu minsi 60 nyuma yo gutangazwa mu gitabo cya federasiyo.

Dichloromethane ni imiti iteje akaga, ishobora gutera kanseri zitandukanye n'ibibazo bikomeye by'ubuzima, harimo na kanseri y'ibihaha, kanseri y'ibihaha, kanseri y'idubu, kanseri yo mu bwonko, kanseri yo hagati. Byongeye kandi, itwara kandi ibyago byo kwangirika kwa neurotoxie. Kubwibyo, iryo tegeko risaba ibigo bigabanya buhoro buhoro umusaruro, gutunganya, no gukwirakwiza Dichloromethane kubaguzi ndetse ninganda ninganda nubucuruzi, harimo no gukandamizwa murugo. Gukoresha umuguzi bizahita byihuta mugihe cyumwaka umwe, mugihe ikoreshwa ryinganda nubucuruzi bizabuzwa mumyaka ibiri.

Kuri ibintu bike hamwe nibidukikije byingenzi mubidukikije byateye imbere mu nganda, Iri tegeko ryemerera kugumana Dichloromethane kandi rishyiraho uburyo bw'ingenzi bwo kurengera abakozi - gahunda yo kurengera imiti. Iyi gahunda ishyiraho imipaka igaragara, igenzura ibisabwa, hamwe no guhugura abakozi no kumenyesha inshingano zo kurwanya Dichloromethane mu iterabwoba ribangamira imiti n'ibindi bibazo biterwa no guhura nimiti nkiyi. Kumurimo uzakomeza gukoresha Dichloromethane, umubare munini wibigo bigomba kubahiriza amategeko mashya mugihe cyamezi 18 nyuma yo kurekura amategeko no gukora ikurikirana risanzwe.

Izi mfunguzo zirimo zirimo:

Gutanga indi miti, nk'imiti ikonje ishobora kugereranya buhoro buhoro hydrofluo k'amashanyarazi yangiza mu mico ya Biparsan no gukora;

Umusaruro wibinyabiziga byateye amashanyarazi;

Imfashanyo yo gutunganya muri sisitemu zifunze;

Gukoresha imiti ya laboratoire;

Inganda za plastike na reberi, harimo umusaruro wa Polycarbonate;

Kuborana.
