Machibidoro dichloromethane ewebata, mwepụta amachibidoro maka iji ụlọ ọrụ mmepụta ihe

Na Eprel 30, 2024, United States Environmental Protection Agency (EPA) nyere mmachibido iwu iji dichloromethane ọtụtụ ebumnuche dịka ụkpụrụ njikwa ihe egwu nke Iwu Njikwa Ihe Na-egbu egbu (TSCA). Nkwagharị a bu n'obi ịhụ na enwere ike iji dichloromethane dị oke egwu mee ihe n'enweghị nsogbu site na mmemme nchekwa ndị ọrụ zuru oke. Mmachibido iwu a ga-arụ ọrụ n'ime ụbọchị 60 ka ebipụtachara ya na Federal Register.

Dichloromethane bụ kemịkalụ dị ize ndụ, nke nwere ike ibute ọrịa kansa dị iche iche na nsogbu ahụike siri ike, gụnyere ọrịa imeju, kansa akpa ume, ọrịa ara ara, ọrịa kansa ụbụrụ, ọrịa leukemia na sistem ụjọ akwara. Na mgbakwunye, ọ na-ebukwa ihe ize ndụ nke neurotoxicity na mmebi imeju. Ya mere, mmachibido iwu ahụ chọrọ ka ụlọ ọrụ ndị dị mkpa jiri nwayọọ nwayọọ belata mmepụta, nhazi na nkesa dichloromethane maka ndị na-azụ ahịa na ọtụtụ ụlọ ọrụ mmepụta ihe na azụmahịa, gụnyere ịchọ mma ụlọ. A ga-ewepụ ojiji ndị ahịa n'ime otu afọ, ebe a ga-amachibido iji ụlọ ọrụ mmepụta ihe na azụmaahịa n'ime afọ abụọ.

Maka ihe atụ ole na ole nwere ihe dị mkpa na gburugburu ebe mepere emepe nke ukwuu, mmachibido iwu a na-enye ohere maka njigide dichloromethane ma guzobe usoro nchebe isi nke ndị ọrụ - Atụmatụ Nchedo Chemical Ebe Ọrụ. Atụmatụ a na-edobe oke ikpughe siri ike, ihe nleba anya, na ọzụzụ onye ọrụ na ọrụ ngosi maka dichloromethane iji chebe ndị ọrụ pụọ na ihe iyi egwu nke ọrịa kansa na nsogbu ahụike ndị ọzọ nke ikpughe na kemịkalụ dị otú ahụ. Maka ebe ọrụ ga-aga n'ihu na-eji dichloromethane, ọnụ ọgụgụ ka ukwuu nke ụlọ ọrụ kwesịrị ịgbaso ụkpụrụ ọhụrụ n'ime ọnwa 18 ka ahapụchara iwu nchịkwa ihe ize ndụ ma na-eduzi nlekota mgbe niile.

Ojiji igodo ndị a gụnyere:
