Regulatory Status ntawm Dichloromethane los ntawm Cheeb Tsam
Tebchaws Meskas (EPA Regulation)
Cov neeg siv khoom - qib xim tshem tawm uas muaj dichloromethane (DCM) raug txwv. Raws li kev tswj xyuas, dichloromethane tseem tuaj yeem siv rau kev lag luam thiab kev lag luam, tab sis yuav tsum ua raws li cov qauv kev nyab xeeb nruj.
European Union (REACH Txoj Cai)
Kev siv dichloromethane hauv cov neeg siv khoom- qib xim tshem tawm raug txwv. Nws siv rau cov hom phiaj kev lag luam raug tso cai tom qab siv cov kev tswj hwm kev pheej hmoo tsim nyog.
Lwm thaj chaw (Asia, Middle East, thiab lwm yam)
Feem ntau cov cheeb tsam tsis txwv kev siv dichloromethane.

Vim li cas Dichloromethane raug txwv
Cov laj thawj tseem ceeb rau kev txwv dichloromethane:
- Kev phom sij loj rau kev noj qab haus huv: Sau npe tias muaj peev xwm carcinogen; tuaj yeem ua rau mob qog noj ntshav, mob ntsws, thiab mob pancreatic.
- Neurotoxicity: Ua rau lub hauv nruab nrab lub paj hlwb puas, ua rau mob taub hau, kiv taub hau, tsis meej pem, loog, lossis coma.
- Kev puas tsuaj rau lub cev: Ntev ntev - kis tau tuaj yeem ua rau lub siab, lub raum, thiab lub plawv puas.
- Kev pheej hmoo ua rau tuag taus: Cov concentration ntau tuaj yeem ua rau asphyxiation lossis carbon monoxide lom, ua rau tuag taus.
- High volatility: Volatilizes sai heev; nce kev pheej hmoo ntawm kev nqus pa hauv qhov chaw tsis zoo.
