Dichloromethane (DCM), mankhwala omwe ali ndi formula ya CH₂Cl₂, akadali chosungunulira chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale ambiri chifukwa cha mawonekedwe ake apadera. Madzi opanda mtundu, osasunthika awa okhala ndi fungo lofewa komanso lokoma amayamikiridwa chifukwa cha luso lake lalikulu posungunula mitundu yambiri ya mankhwala achilengedwe, zomwe zimapangitsa kuti ikhale chinthu chofala kwambiri mu zochotsa utoto, zochotsa mafuta, ndi zopangira aerosol. Kuphatikiza apo, ntchito yake monga wothandizira popanga mankhwala ndi zakudya, monga khofi wopanda kafeini, ikuwonetsa kufunika kwake kwakukulu m'mafakitale.
Komabe, kugwiritsa ntchito kwambiri dichloromethane kumayenderana ndi nkhawa zazikulu pa thanzi komanso chilengedwe. Kukhudzidwa ndi nthunzi ya DCM kungayambitse mavuto aakulu pa thanzi la anthu, kuphatikizapo kuwonongeka kwa dongosolo la mitsempha. Pakakhala kuchuluka kwambiri, imadziwika kuti imayambitsa chizungulire, nseru, ndipo, pazochitika zazikulu, imatha kupha. Chifukwa chake, njira zodzitetezera zolimba zomwe zimagogomezera mpweya wabwino komanso zida zodzitetezera ndizofunikira kwa ogwira ntchito.
Mabungwe oteteza zachilengedwe akuyang'ananso kwambiri pa momwe dichloromethane imakhudzira. Popeza ndi Volatile Organic Compound (VOC), imathandizira kuipitsa mpweya ndipo imatha kupanga ozone pansi. Ngakhale kuti imakhalabe mumlengalenga, imafunika kuyang'aniridwa mosamala kuti itulutsidwe ndi kutayidwa.
Tsogolo la dichloromethane limadziwika ndi kulimbikira kwa zatsopano. Kufunafuna njira zina zotetezeka komanso zokhazikika kukuchulukirachulukira, chifukwa cha zovuta zowongolera komanso kusintha kwapadziko lonse lapansi kupita ku chemistry yobiriwira. Ngakhale dichloromethane ikupitilira kukhala chida chofunikira kwambiri m'magwiritsidwe ntchito ambiri, kugwiritsidwa ntchito kwake kwa nthawi yayitali kukuwunikidwa mozama, kulinganiza magwiridwe ake osayerekezeka ndi kufunika kokhala malo otetezeka pantchito komanso malo abwino.
