I-Dichloromethane (DCM), ikhemikhali equkethe ifomula i-CH₂Cl₂, ihlala iyisithako esisetshenziswa kabanzi ezimbonini eziningi ngenxa yezakhiwo zayo eziyingqayizivele. Lolu ketshezi olungenambala, oluguquguqukayo olunephunga elimnandi, luyaziwa ngokusebenza kahle kwalo ekuncibilikiseni uhla olukhulu lwamakhemikhali e-organic, okwenza lube yisithako esivamile kuma-paint strippers, ama-degreasers, kanye nama-aerosol formulations. Ngaphezu kwalokho, indima yalo njenge-ejenti yokucubungula ekukhiqizweni kwemithi nemikhiqizo yokudla, njengekhofi engena-caffeine, igcizelela inani layo elibalulekile lezimboni.
Kodwa-ke, ukusetshenziswa kabanzi kwe-dichloromethane kuhambisana nokukhathazeka okukhulu ngempilo kanye nemvelo. Ukuchayeka emisipheni ye-DCM kungaba yingozi enkulu empilweni yabantu, okuhlanganisa nomonakalo ongaba khona ohlelweni lwezinzwa oluphakathi. Uma kugxilwe kakhulu, kwaziwa ukuthi kubangela isiyezi, isicanucanu, futhi, ezimweni ezimbi kakhulu, kungaba yingozi. Ngenxa yalokho, izinqubo zokuphepha eziqinile ezigcizelela ukuphefumula okwanele kanye nemishini yokuzivikela yomuntu siqu ziyimpoqo kubaphathi.
Izinhlangano zemvelo nazo zigxile emthonjeni we-dichloromethane. Njengoba ihlukaniswe njenge-Volatile Organic Compound (VOC), inegalelo ekungcolisweni komoya futhi ingakha i-ozone esezingeni lomhlaba. Ukuqhubeka kwayo emkhathini, nakuba iphakathi nendawo, kudinga ukuphathwa ngokucophelela kokukhishwa kwayo nokulahlwa kwayo.
Ikusasa le-dichloromethane liphawulwa ukushisekela izinto ezintsha. Ukusesha ezinye izindlela eziphephile nezisimeme kuyashesha, kuqhutshwa yizingcindezi zomthetho kanye noshintsho lomhlaba wonke oluya kumakhemikhali aluhlaza. Nakuba i-dichloromethane iqhubeka nokuba ithuluzi elibalulekile ezinhlotsheni eziningi zokusebenza, ukusetshenziswa kwayo isikhathi eside kuhlolwa ngokujulile, kulinganiswa ukusebenza kwayo okungenakuqhathaniswa nokubaluleka kwezindawo zokusebenza eziphephile kanye nendawo enempilo.
