Kei te noho puku ngā mōrearea hauora o ngā tipu uku i roto i tō hapori?
He aha te take e kōrero anō ai te iwi mō ngā tūponotanga ki te hauora o ngā tipu uku?
Peia atu i tētahi kaupapa rori nui, ā, ka kite koe i ngā whare pupuri rakau teitei, i ngā whitiki kawe me ngā hau mamaoa: te āhua o tētahi tipu uku. Mō ngā kaimahi kirimana, he mahi me te ahunga whakamua ēnei whare, engari mō ngā kainoho, he pātai nui kei te ara ake - kei te rere puku ngā mōrearea hauora o ngā tipu uku ki ngā rohe tata? I roto i ngā tau e rima kua pahure ake nei, e whakaatu ana a Google Trends i te pikinga 60% o ngā rapunga mō te "hauora tukunga tipu uku," he tohu e hiahia ana ngā hapori, ngā kaiinihua me ngā kaipupuri moni ā-rohe ki te mārama. Ka keri tēnei tuhinga ki tua atu i te auahi hei wetewete i ngā kōrero a te pūtaiao, te ture me te hangarau o te papa mō ngā mōrearea pea, me te mea nui, he aha tāu e taea ai mēnā kei te whakamaheretia he tipu ki te taha.
He aha tonu te mea e puta mai ana i te puranga tipu uku?
Ko te hanga uku wera (HMA) e arotahi ana ki te whakamaroke i ngā konganuku i te 300 °C me te paninga ki te uku. Mā te whakakotahitanga o te wera nui, ngā here hinu me te papa uku hangarua (RAP) ka tukuna he ranunga o ngā poke:
- Matūriki (PM10 me te PM2.5) — he maramara puehu ririki me ngā warowaihā kua whakakōkīhia e uru hohonu ana ki roto i te kiko o te pukahukahu.
- Ngā hauwaiwai kakara polycyclic (PAH) — he akomanga o ngā matū neke atu i te 100, ā, ko ētahi o ēnei kua whakarōpūtia e te IARC hei matū whakaputa mate pukupuku Rōpū 1, 2A rānei.
- Ngā wāhanga wairewa-benzene — e whakamahia ana hei whakakapi mō ngā huānga paitini ake i roto i ngā kohu bitumen.
- Te hauota waro, te hauota whanariki me ngā waikura hauota — he hau e pā ana ki te ahotea manawa me te hanganga kohu.
I te whakawhiti mai i te matū ki te mate urutā, he mārama te pātai whai muri mai: e hia o ēnei mea ka tae atu ki te rohe taiapa?
Kia Pēhea te Tata rawa? Ngā Taunakitanga Mate Urutā mō ngā Mōrearea Hauora o ngā Tipu Āpara
I roto i tētahi tātaritanga nui o te tau 2020 i roto i te Environmental Research, i whakakotahihia e 18 ngā rangahau mahi me ngā rangahau hapori. Ko ngā kaimahi he ≥ 10 tau te roa o te pānga o te HMA i whakaatu i te pikinga o te mōrearea mate pukupuku pūkahukahu 34% i muri i te whakarerekētanga ki te momi hikareti. Ahakoa kāore ngā kainoho e pāngia e te horopeta kukū ōrite, he mea nui te tata. I whakatauirahia e te Aromatawai Pānga Hauora (HIA) o te tau 2022 i North Carolina te horapa o te PM2.5 mai i tētahi tipu 300 K-tana-ia-tau, ā, i matapaetia:
- Rohe 0–500 m: tāpiri 1.3 µg/m³ toharite ā-tau PM2.5; he pikinga nui ā-tatauranga mō ngā haerenga ki te ER e pā ana ki te mate huango i waenga i ngā tamariki.
- Rohe 500–1 500 m: pikinga 0.4 µg/m³; ka taea te ine engari he iti ake te taumahatanga hauora.
- Neke atu i te 2 000 m: te mōrearea kua whakatauirahia, kāore e taea te wehewehe mai i te papamuri.
Whakamāoritanga? Mena kei roto i te hawhe maero te kura, te whare reti rānei o tāu tamaiti, e ai ki te whakaaro pūtaiao tera pea he mōrearea tāpiri - he mea kāore i te tino pānuitia e ngā poari rohe.
Ehara te Teitei o te Puranga i te Mea Katoa: Te Āputa o ngā Tukunga Rerenga
He pai ki ngā kaupapa kōrero a te umanga te whakanui i ngā puranga teitei me ngā tātari whare putea hou; e rua e whakaiti ana i ngā tukunga mai i te pūtake o te hau. Heoi, e whakaatu ana te rarangi tukunga a te EPA i te tau 2018 o ngā Hot Mix Asphalt Plants e tae atu ana ki te 55% o ngā PAH katoa ka puta hei tukunga rere - te puehu e tangohia ana i ngā moenga taraka, ngā warowaihā e mimiti ana mai i ngā whare rokiroki tuwhera, me te hau o te utauta i roto i te kāinga. He maha ngā wā ka "hongi" ngā hoa noho tata ki te hau i te ara i mua i te kitenga atu nā te mea ka haere ēnei puna iti ki te taha, kaua ki te piki ake. Arā, tera pea ka kitea e tō ihu te raruraru i mua i te kitenga o te aroturuki kounga hau - āe, he mea āta whakaaro taua hapa kupumahi.
Kōnae Take: He Hapori i Whakakāhore kia Noho hei Kānari
I te tau 2019, i tūtaki te tāone o Riverside, Oregon (taupori 4 200) ki tētahi whare HMA 450 K-tana i whakaarohia. I whakatūria e ngā kainoho te Clear Air Riverside, he rōpū kore-moni, ā, i utua e rātou he $12 000 o ngā pūoko PAH kawe. I roto i ngā rā 90, i piki ake te toharite o ngā kukū PAH i te awatea 400 m mai i te papa tipu mai i te 7 ng/m³ (i mua i te hanganga) ki te 27 ng/m³, ā, i eke ki te 110 ng/m³ i te wā e whakatōngia ana ngā ara i te ahiahi. Nā ēnei raraunga, i whakakahoretia e te poari ā-rohe te whakaaetanga kounga hau, me te kī "he nui ake te mōrearea mate pukupuku mō te oranga katoa i runga ake i te 1 i roto i te 10 000." Ko te mea nui: ka taea e te pūtaiao ā-iwi te neke i ngā ngira ture ina inehia ngā mōrearea hauora o ngā tipu uku i te wā tūturu.
Ka taea e ngā hangarau hou te whakakakariki i te uku?
Ko te hanga o roto, te whakamahana hiko wāhanga, ngā taupoki hopu paoa kikorangi me ngā tāpiringa ranunga mahana e whakaiti ana i te pāmahana hanga ki te 230 °C, ka whakaitihia katoatia ngā tukunga mā te 30–50%. E ai ki te whakatau a te Carbon Trust o te UK, ka taea e te tipu te whakaheke i te PM2.5 mā te 65% ki te whakataurite ki te hangarau o te tekau tau atu i 1990. Heoi anō, ahakoa ngā whare tino iti-tukunga ka tukuna ētahi PAH; kāore he tohu kore o te pihi horopeta-tauhohenga. Ko te tino take: ka whakaitihia e ngā mana whakahaere hangarau engari kāore e whakakore i ngā mōrearea hauora o te tipu uku, inā koa mō ngā kaiwhakawhiwhi tairongo i roto i te 500 m.
He aha ngā mahi a muri ake mā ngā kaipupuri whare, ngā kaimahi me ngā kaiwhakamahere tāone?
Mena kei te noho tata koe:
- Tonoa te whakaaetanga Taitara V a te tipu — kei roto e whakarārangihia ana ngā poke katoa kua whakahaeretia; whakatairitea ki ngā paerewa hau taiao a te kawanatanga.
- Haere ki ngā huihuinga tūmatanui, me te tono kia whakatūria he aroturuki PM2.5 e mau tonu ana i te taha taiapa; me tuku ngā raraunga ki te paetukutuku DEQ i roto i ngā rā 30 e ai ki te whakahoutanga ture 2023 a te EPA.
- Whakaarohia he pūoko taumata-hapori (PurpleAir, AirBeam) hei takiuru i ngā taunakitanga; ka whakaaetia e ngā kōti ngā raraunga kua whakamanahia.
Mena kei te mahi koe i te wheketere:
- Me tohe kia whakamahia ngā taputapu manawa haurua-kōpare me ngā kātīra OV-P100 i te wā e horoia ana ngā silo; e whakatakoto ana te 29 CFR 1910.1001 a OSHA i te 5 mg/m³ TWA mō ngā kohu bitumen, engari e taunaki ana a NIOSH kia < 1 mg/m³.
- Panahia ngā huringa hurihuri; ka taurite te mōrearea o te mate pukupuku pūkahukahu me ngā tau whakareatanga tāpiripiri.
Ki te noho koe i runga i tētahi Poari Whakamahere:
- Whakatakotoria he ārai 1,000 m mō ngā whare tiaki kaumātua e tata ana ki ngā kura, ngā hōhipera me ngā pokapū tiaki kaumātua; he rite tēnei ki ngā aratohu i Tiamana me Hōrana.
- Me tirotiro i te puehu rerenga i ia toru marama, kaua i ia tau; me whakarite kia kati ngā moenga taraka uta me ngā moenga taraka kua hipokina.
I a koe e neke ana ki te ao ture, kia maumahara ko te utu mō ngā kaihanga uku parahanga e utua ana e ngā kaiinihua nama he 25–30% teitei ake i te tekau tau ki muri—he mea whakatenatena tēnei mō ngā whakapainga tūao.
Ko te Whakamutunga—Ka taea te Whakahaere i ngā Mōrearea Hauora o ngā Tipu Āpara, he Mea rānei e Whakakore ana i te Whakaaetanga?
E ai ki te pūtaiao he tūturu ngā mōrearea, he mea whakawhirinaki ki te horopeta, ā, he tino kaha rawa atu i roto i te radius 500 m. Ka taea e te hangarau te whakaiti i ngā tukunga ki te haurua, engari kāore e taea te whakakore. Ko te mataara o te hapori, ko ngā raraunga mārama me te rohenga matatau tonu ngā parepare kaha rawa atu. I mua i tō hainatanga i taua wāhanga hou—i mua rānei i tō whakaae ki tētahi tuku mahi i te tipu—pātai atu ki a koe anō: "He nui ake ngā painga ōhanga e kitea ana i te pikinga ka taea te ine i te mōrearea mate pukupuku mō te oranga katoa?" Ko te marea whai mātauranga anake ka taea te whakataurite i ngā tono hanganga me te tika taketake ki te manawa i te hau ma.
