Lus Cim: Hauv cov xwm txheej ib txwm muaj, DCM feem ntau raug cais raws li cov khoom tsis yog -flammable. Nws tsis muaj flash point. Nws qhov teeb meem tseem ceeb yog toxicity thiab vapor inhalation, es tsis yog hluav taws kub.

1. Tus nqi toxicity

2. Cov teebmeem tshwm sim

Dichloromethane DCM yog absorbed sai heev los ntawm inhalation thiab tawv nqaij. Hauv daim siab, nws yog metabolized rau carbon monoxide (CO), formaldehyde, thiab carbon dioxide. Cov pa roj carbon monoxide tsim khi rau hemoglobin, txo cov ntshav oxygen - nqa lub peev xwm thiab tsim cov teebmeem zoo ib yam li CO lom.
 

Cov tsos mob hnyav muaj xws li:

• Central nervous system kev nyuaj siab: mob taub hau, kiv taub hau, qaug zog, tsis meej pem, poob ntawm kev sib koom tes
• Kev ua pa ua pa: hnoos, hauv siab nruj, ua tsis taus pa
• xeev siab thiab ntuav
• Kev ntxhov siab hauv plawv: palpitations, mob hauv siab
• Kev tsis nco qab thiab kev tuag ntawm qhov siab heev
• Daim tawv nqaij thiab qhov muag khaus thaum ntsib ncaj qha

3. Ntev thiab ntev -Cov teebmeem

Carcinogenicity: Lub Koom Haum Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kev Kho Mob (IARC) faib cov dichloromethane ua Pawg 2A (tej zaum carcinogenic rau tib neeg). US National Toxicology Program (NTP) teev nws li "tsim nyog xav tias yuav yog tib neeg carcinogen." Ntev- kev tshawb fawb txog kev nqus pa hauv cov tsiaj tau pom tias muaj cov kab mob siab, ntsws, thiab qog nqaij hlav qog.
Kev puas tsuaj rau lub cev: Kev rov ua dua lossis ntev ntev tuaj yeem ua rau lub siab, lub raum, thiab cov ntshav puas.
Neurological teebmeem: Kev raug mob ntev tuaj yeem ua rau muaj kev puas siab puas ntsws, nco tsis tau, thiab hloov tus cwj pwm.
Kev yug me nyuam thiab kev loj hlob toxicity: Tsiaj cov kev tshawb fawb tau pom tias muaj kev loj hlob thiab kev loj hlob ntawm cov koob tshuaj ntau.
 

1. Kev nqus pa: txav mus rau huab cua ntshiab tam sim ntawd, muab cov pa oxygen yog tias xav tau
