Kua whakaarohia e te Tari Tiaki Taiao o Amerika te aukati i te whakamahinga o te methylene chloride i roto i ngā mahi kaihoko katoa me te nuinga o ngā mahi ahumahi me ngā mahi arumoni. I puta mai tēnei tono hou i muri i te otinga o te aromatawai mōrearea a te tari i te Whiringa-ā-rangi 2022 i kitea ai ko te pānga ki ngā whakarewa ka pā kino ki te hauora pērā i te mate ate me te mate pukupuku.
Kei roto i ngā momo hua te methylene chloride, tae atu ki ngā piripiri, ngā tango peita, me ngā tango hinu. E whakamahia whānuitia ana hoki hei rauemi mata mō te hanga i ētahi atu matū. E ai ki te whakatau tata a te US Environmental Protection Agency, neke atu i te 900,000 ngā kaimahi me te 15 miriona kaihoko e pāngia ana e te methylene chloride i ngā wā katoa.
Ko te matū nei te tuarua o ngā matū kua arotakehia i raro i te Ture Whakahaere Matū Paitini kua whakahoutia (TSCA), e hiahia ana kia arotakehia e te Tari Tiaki Taiao te haumaru o ngā matū arumoni hou me ngā matū arumoni o mua. Ko te whāinga a te tari he whakamutu i te hanga, te tukatuka me te tohatoha o te methylene chloride i roto i ngā marama 15.
Kāore ētahi whakamahinga o te methylene chloride i roto i tēnei aukati, tae atu ki tōna whakamahinga hei matū. Hei tauira, ka whakamahia tonutia i roto i te hanga o te hauhautanga hydrofluorocarbon-32, i whakawhanakehia hei huarahi kē atu ki ngā huarahi kē atu he nui ake te kaha ki te whakamahana ā-ao me/ranei te whakaiti i te ozone.
"E whakapono ana mātou kei te haumaru tonu te methylene chloride mō te whakamahinga a te ope taua me te kāwanatanga ā-motu," te kī a Michal Friedhoff, te kaiwhakahaere hono o te Tari Haumaru Matū me te Ārai i te Parahanga o te Taiao (EPA), i tētahi huihuinga pāpāho i mua i te panuitanga. "Me mahi te EPA hei tiaki i te haumaru o ngā kaimahi."
I mihi atu ētahi rōpū taiao ki te tono hou. Heoi, i whakapuaki hoki rātou i ō rātou āwangawanga mō ngā tūponotanga ki te ture e whakaae ana kia whakamahia tonutia te methylene chloride mō te tekau tau pea e whai ake nei.
I kī a Maria Doa, te kaiwhakahaere matua o te kaupapa here matū i te Environmental Defense Fund, ka noho tonu taua whakamahinga roa hei tūponotanga mō ngā hapori e noho tata ana ki ngā wāhi kua whakakorehia. I kī a Doa me whakapoto e te Environmental Protection Agency te roa o te whakakorenga, me whakatakoto rānei he here tāpiri ki ngā tukunga methylene chloride mai i ēnei tipu.
I taua wā tonu, i kī te American Chemistry Council, he rōpū hokohoko e tohu ana i ngā kaihanga matū, ka pā pea ngā ture kua whakaarohia ki te mekameka tuku. I roto i tētahi kōrero, i kī te rōpū mā te whakahekenga tere o te hanga methylene chloride ka heke iho i te haurua. I kī te rōpū, ka pā pea ngā whakahekenga ki ētahi atu ahumahi pērā i ngā rongoā, inā koa mēnā "ka whakatau ngā kaihanga ki te whakamutu katoa i te hanga."
Ko te Methylene chloride te tuarua o ngā matū tekau e whakamahere ana te Tari Tiaki Taiao ki te aromatawai mō ngā tūponotanga mō te hauora tangata me te taiao. Tuatahi, ko te asbestos. I kī a Freedhoff ko ngā ture mō te tuatoru o ngā matū, ko te perchlorethylene, ka rite pea ki ngā ture hou mō te methylene chloride, tae atu ki te aukati me ngā tiakitanga kaha ake mō ngā kaimahi.
