Kei te whakaaro te Tari Tiaki Taiao o Amerika (EPA) kia aukatia te nuinga o ngā whakamahinga o te dichloromethane (methylene chloride) i raro i te Ture Whakahaere Matū Paitini (TSCA), e whakahaere ana i te kaupapa here matū o Amerika. He whakarewa taiwhanga whānuitia te dichloromethane i roto i ngā hua pēnei i ngā piripiri, ngā hiri, ngā tango hinu me ngā whakangawari peita. Koinei te matū tuarua kua whakahaeretia i raro i te tukanga Tsca kua whakahoutia, i hangaia i te tau 2016, whai muri i te asbestos i te tau kua hipa.
Kei roto i te tono a te EPA kia aukatia te hanga, te tukatuka me te tohatoha o te dichloromethane mō ngā whakamahinga katoa a ngā kaihoko, kia aukatia te nuinga o ngā whakamahinga ahumahi me ngā whakamahinga arumoni, me ngā mana whakahaere tino pakari i te wāhi mahi mō ētahi atu whakamahinga.
Ka whakahaeretia te whakamahinga o te methylene chloride i roto i te taiwhanga e te kaupapa, ā, ka whakahaeretia hoki e te mahere tiaki matū i te wāhi mahi, ehara i te aukati. Ka whakawhāitihia e te mahere te pānga ki ngā mahi ki te toharite o te 2 wāhanga ia miriona (ppm) mō ngā hāora 8 me te 16 ppm mō ngā meneti 15.
Ka Whakatakotohia e te Tono Hou a te EPA he Here Hou mō ngā Taumata Whakamārama o te Dichloromethane i roto i ngā Taiwhanga
Kua tautuhia e te Tari Tiaki Taiao te mōrearea o ngā pānga kino ki te hauora o te tangata mai i te manawa me te pānga ki te kiri o te methylene chloride, tae atu ki te paitini roro me ngā pānga ki te ate. I kitea anō e te tari ko te manawa roa me te pānga ki te kiri o te matū ka piki ake te mōrearea o te mate pukupuku.
I te panuitanga o te tono a te tari i te 20 o Paenga-whāwhā, i kī te Kaiwhakahaere EPA a Michael Regan: "He mārama te pūtaiao kei muri i te methylene chloride, ā, ka taea e ōna pānga te pā kino ki te hauora, tae atu ki te mate. He tokomaha rawa ngā tāngata kua mate ō rātou whanaunga nā te paihana nui." whānau".
Mai i te tau 1980, e ai ki te EPA, neke atu i te 85 ngā tāngata kua mate i te pānga kino ki te methylene chloride. Ko te nuinga o rātou he kaimahi whakapaipai whare, ko ētahi o rātou he tino whakangungua, ā, e mau ana i ngā taputapu tiaki whaiaro. I kite te tari he maha atu ngā tāngata e "pāngia ana e ngā pānga hauora kino me te roa, tae atu ki ētahi momo mate pukupuku."
I te wā o te whakahaerenga a Obama, i whakatau te Tari Tiaki Taiao he "tūponotanga kino ki te hauora" ngā mīhini tango peita kei roto te methylene chloride. I te tau 2019, i aukatia e te tari te hoko o aua hua ki ngā kaihoko, engari i whakawakia e ngā kaiwhakatairanga hauora tūmatanui i kī kāore i tino tutuki ngā ture, ā, me tere ake te mahi i ngā mahi kaha ake.
E matapaetia ana e te EPA ka whakatinanahia katoatia te nuinga o ngā huringa hou kua whakaarohia i roto i ngā marama 15, ā, ka tutuki ki te 52 ōrau te aukati i te whakaputanga ā-tau mō ngā whakamahinga whakamutunga a te TSCA. I kī te tari mō te nuinga o ngā whakamahinga dichloromethane e whakaaro ana rātou ki te aukati, he rite tonu te utu mō ngā hua rerekē.
Heoi, i whakautu tonu te Kaunihera Matū o Amerika (ACC), e tohu ana i ngā kamupene matū o Amerika, ki te EPA, me te kī he "pūhui nui" te methylene chloride e whakamahia ana hei hanga i ngā hua kaihoko.
Hei whakautu ki te kōrero a te EPA, i whakapuaki te rōpū ahumahi i tōna āwangawanga kei "whakauru mai tēnei i te koretake me te whakapoauau ture" ki ngā herenga whakaraerae methylene chloride a te US Occupational Safety and Health Administration o nāianei. E kī ana te ACC kāore te EPA i "whakatau he mea tika" kia whakatakotohia he herenga whakaraerae mahi tāpiri atu ki ērā kua whakatakotoria.
I whakapae anō te rōpū tautoko i te EPA mō te korenga e arotake katoa i te pānga o āna whakaaro ki te mekameka tuku. "Tērā pea ka pā nui te rahi o aua whakahekenga tere ki te mekameka tuku mena he herenga kirimana ā ngā kaihanga me tutuki e rātou, mena rānei ka whakatau ngā kaihanga ki te whakamutu katoa i te whakaputa," te whakatūpato a te ACC. ka pā ki ngā tono nui, tae atu ki te mekameka tuku rongoā me ētahi tono nui e pāngia ana e te waikura kua tautuhia e te EPA."
Kua roa e tatarihia ana te aukati a te EPA mō ngā hua kaihoko, engari e whakaae ana kia whakamahia tonutia ngā hua arumoni.
Kua whai mana te whakahoutanga o te Ture Whakahaere Matū Paitini, e roa nei e tatarihia ana, e whakahaere ana i te ture whakahaere o ngā matū i te Hononga o Amerika.
E whakaatu ana te pūrongo a te Whare Paremata o te UK me kaha ake te mahi a te kāwanatanga ki te whakatika i ngā take e pā ana ki te pūtaiao.
I kitea e te waka rererangi Cassini a NASA te puehu me te hukapapa e karapoti ana i te Ao, he rau miriona tau noa iho te pakeke.
