Ko te Dichloromethane (DCM), he matū kei roto te tātai CH₂Cl₂, he mea whakamahi whānuitia tonutia puta noa i ngā ahumahi maha nā ōna āhuatanga tino pai. Ko tēnei wai kore tae, he pūngāwerewere me te kakara reka, he mea utu nui mō tōna whai huatanga ki te whakarewa i te whānuitanga o ngā matū waro, ā, he mea noa iho i roto i ngā tango peita, ngā tango hinu, me ngā hanganga aerosol. Hei tāpiri, ko tōna tūranga hei kaihoko tukatuka i roto i te hanga rongoā me ngā hua kai, pērā i te kawhe kore-kawheina, e whakaatu ana i tōna uara ahumahi nui.
Heoi, ko te whakamahinga whānui o te dichloromethane he mea nui ki te hauora me te taiao. Ka taea e te pānga o ngā kohu DCM te whakararu i te hauora o te tangata, tae atu ki te kino pea ki te pūnaha io matua. Mēnā he nui te kukū, e mōhiotia ana ka pāngia e te whanoke, te whakapairuaki, ā, i ngā wā kino, ka mate pea. Nō reira, he mea whakahau kia whakamahia ngā tikanga haumaru pakari e aro ana ki te hauhautanga me ngā taputapu tiaki whaiaro mō ngā kaimahi.
Kei te aro nui hoki ngā tari taiao ki te pānga o te dichloromethane. E kiia ana he matū matū waro (VOC) e whakarōpūtia ana, ā, ka whai wāhi atu ki te parahanga o te hau, ā, ka taea te hanga i te ozone o te whenua. Ahakoa he iti te noho o te hau i roto i te hau, me āta whakahaere tōna tukunga me te whakakorenga.
Ko te heke mai o te dichloromethane e tohuhia ana e te akiaki i te auahatanga. Kei te tere haere te rapu i ngā huarahi haumaru ake, pumau ake, e akiakihia ana e ngā pēhanga ture me te nekehanga ā-ao ki te matū matomato ake. Ahakoa kei te noho tonu te dichloromethane hei taputapu nui i roto i te maha o ngā tono, kei te arotakehia tōna whakamahinga mō te wā roa, me te whakataurite i tōna whai huatanga kore e taea te whakataurite ki te hiranga mō ngā wāhi mahi haumaru ake me te taiao hauora ake.
