I ngā tau tata nei, kua piki haere te aro ki te oranga tonutanga me te whakaiti i te pānga ki te taiao o ngā momo ahumahi. Kāore te umanga tā i rerekē, me te maha haere o ngā kamupene e rapu ana i ngā huarahi pai mō te taiao hei whakakapi i ngā tikanga tā tuku iho. Ko tētahi otinga kua tino rongonui ko te pūreretā eco-solvent. He whānuitanga o ngā painga ka tukuna e ēnei pūreretā, he mea tino pai mō te tā oranga tonutanga.
Ko tētahi o ngā painga matua ongā pūreretā whakarewa taiaoko tā rātou whakamahinga i ngā waituhi hoa-taiao. He rerekē ki ngā waituhi whakarewa tuku iho, kei roto nei ngā matū waro mimiti kino (VOC), he mea hanga ngā waituhi whakarewa-taiao ki ngā rauemi kore-paitini, kore-mura. Mā tēnei ka whakaitihia te tukunga o ngā matū waro mimiti i te wā o te tukanga tā, ka waiho hei kōwhiringa hoa-taiao ake ngā pūreretā whakarewa-taiao.
Hei tāpiritanga, he mea hanga motuhake ngā waituhi whakarewa-taiao kia piri ki ngā momo rauemi, tae atu ki te winīri, te papanga, me te pepa. Mā tēnei whānuitanga ka taea te whakamahi i ngā mahi tā pumau ake, nā te mea ka kore e hiahiatia he maha ngā hangarau tā, te whakamahi rānei i ngā piripiri kino. Mā ngā pūreretā whakarewa-taiao ka whakarite he hua mutunga kounga teitei, me te whakaiti i te para me te pānga ki te taiao.
Ko tētahi atu painga nui o ngā pūreretā whakarewa-taiao ko te iti o te kaha e pau ana. Kua hangaia ēnei pūreretā kia penapena i te kaha, ā, he iti ake te hiko e hiahiatia ana hei whakahaere i ngā hangarau tā tuku iho. I tēnei wā e tino hira ana te tiaki i te kaha, ko te whakaiti i te kaha e pau ana i ngā pūreretā whakarewa-taiao ka whai wāhi ki tētahi tukanga tā pumau ake.
Hei tāpiritanga, he nui ngā painga o ngā pūreretā whakarewa-taiao mō te kounga o te hau o roto. Nā te mea he iti ake ngā taumata o ngā matū waro pūngāwerewere e tukuna ana e rātou, he kōwhiringa pai rawa atu ēnei mō ngā tono tā o roto. He tino whai hua tēnei mō ngā pakihi e mahi ana i ngā wāhi kati, pērā i ngā toa hokohoko, he iti ake te kounga o te hau. Mā te whiriwhiri i tētahi pūreretā whakarewa-taiao, ka taea e ēnei pakihi te whakarite i tētahi taiao hauora mō ā rātou kaimahi me ngā kiritaki.
Hei tāpiritanga, e mōhiotia ana ngā pūreretā whakarewa-taiao mō tō rātou pakari me te ātete ki ngā āhuatanga o waho pērā i te hihi UV me te wai. Ko te tikanga he pakari ngā tānga e whakaputaina ana e ēnei pūreretā ahakoa i roto i ngā taiao o waho. Nō reira, ka whakaitihia te hiahia mō ngā tānga anō, ka iti ake te para, ā, ka roa ake te tukanga whakaputa tā.
Hei whakamutunga, he māmā noa iho te tiaki i ngā pūreretā whakarewa taiao, ā, ka whakapakari ake i ō rātou tohu pumau. He maha ngā āhuatanga horoi-ake o ēnei pūreretā e whakaiti ana i te whakapaunga o ngā otinga horoi tāpiri, ngā matū, me te wai. Ehara i te mea ka penapena rauemi anake tēnei engari ka whakaitihia hoki te tukunga o ngā matū kino ki te taiao.
Hei whakarāpopototanga,ngā pūreretā whakarewa taiaoHe maha ngā painga e tukuna ana mō te tānga pumau. Mai i ngā waituhi hoa-taiao ki te iti o te whakapaunga pūngao me te whakapai ake i te kounga o te hau o roto, he taputapu kaha ēnei pūreretā mō ngā pakihi e hiahia ana ki te whakaiti i ō rātou tapuwae taiao. He pakari ngā pūreretā whakarewa-taiao, ā, he ngāwari ki te tiaki, e whakarato ana i tētahi otinga pumau me te kore e whakararu i te kounga. I te mea kei te whakatairanga tonu te ao i te pumau, kei te ārahi ngā pūreretā whakarewa-taiao i te huarahi i roto i te umanga tā.
