Isitshalo Se-Asphalt se-TTM - Umkhiqizi Wemishini Yokuxuba Nokuvuselela I-Asphalt Ochwepheshe Kusukela ngo-2004.
Ingabe Kuphephile Ukuhlala Eduze Nesitshalo Se-Asphalt? Nakhu Okushiwo Yimininingwane Ngempela
Kungani Abathengi Bezindlu Nabaqashi Bezindlu Ngokungazelelwe ku-Google “Ingabe Kuphephile Ukuhlala Eduze Nesitshalo Se-Asphalt?”
Uma uke wadlula i-silo enkulu yesiliva ekhipha amafu amhlophe, kungenzeka ukuthi uzibuze, “ Ingabe kuphephile ukuhlala eduze kwesitshalo se-asphalt? ” —yebo, nami futhi . Eminyakeni emihlanu edlule, izinkundla zezindlu namaqembu e-Facebook angomama aveze lokhu kukhathazeka. Ukukhathazeka kuyiqiniso: ukukhiqizwa kwe-asphalt kuhilela ukomiswa kwezinga lokushisa eliphezulu le-aggregate, ukuxuba ne-bitumen, nokugcina ku-300 °F. Iphunga lodwa libangela izinsimbi zokuxwayisa, kodwa izifundo ezibuyekezwe ontanga zembulani ngempela?
Ukuqapha Ikhwalithi Yomoya: Izinombolo Eziningi Zezindaba Ezidlulayo
Ake sigweme ukwesaba sibheke idatha yangempela . Ngo-2022, iKhomishini yaseTexas Yekhwalithi Yemvelo yabeka ama-monitor aphathekayo 150 m ukusuka esikhungweni sokuxuba izigubhu. Izinyanga ezingaphezu kwe-18:
- I-PM₂.₅ isilinganiso esingu-9.4 μg/m³—ngaphansi kwesiqondiso se-WHO esingu-15 μg/m³.
- Ukufundwa kwe-benzene kufinyelele ku-0.8 ppb, cishe okufanayo nendawo ephithizelayo yedolobha.
- Kutholakale ama-polycyclic aromatic hydrocarbons (ama-PAH), kodwa ku-1/20th izinga litholakale eduze kweziteshi zamandla ezisebenzisa amalahle.
Ukuhumusha? Ezinsukwini eziningi, amazinga okungcola ayengahlukaniseki emazingeni angemuva asemadolobheni. Kodwa-ke, "imicimbi yokulayisha" yesikhashana (lapho amaloli elahla i-aggregate) yayicindezela i-PM₂.₅ ifike ku-35 μg/m³ imizuzu engama-30-45. Yilapho indaba iqondakala khona.
Lokho Ososayensi Abakushoyo Ngokuthi “Ingozi Eyamukelekayo” Uma kuqhathaniswa nalokho Izakhamuzi Ezikunukayo
Nasi isizathu: iphunga aliyona ubuthi. Ikhala lomuntu lingahogela ama-thiol acebile nge-sulfur kuma-parts-per-billion, kodwa umkhawulo wempilo yawo useduze ne-parts-per-million. Ucwaningo lwe-University of Cincinnati lwango-2021 luthole ukuthi izakhamuzi ezingaphakathi kwekhilomitha eli-1 zibike ikhanda eliphindwe kabili kanye nokucasuka komphimbo ngesikhathi sokusebenza kwehlobo, kodwa ukuhlolwa kokusebenza kwamaphaphu kwahlala kujwayelekile. Ngamanye amazwi, ukucasuka ≠ isifo .
Gcina Amafasitela Akho Evaliwe? Ukuthola Okuphambene Nokucabanga
Abacwaningi bafake amasampula omoya angaphakathi emakhaya angu-42. Ngokumangalisayo, izindlu ezine-mechanical ventilation (HRV/ERV) zibonise amazinga aphansi e-PAH kunalezo ezivulwa umoya ngokwemvelo, ngisho nalapho amafasitela evaliwe. Isifundo: ukuvala ikhaya lakho kuyingxenye yempi; ukuhamba komoya okuhlungiwe kuyakuqeda.
Ukubola Kwebanga: Kuseduze Kangakanani Kakhulu?
Iziqondiso zemboni zake zasebenzisa i-mantra ethi “500 ft futhi uphilile.” Amamodeli esimanje okusabalala alandisa indaba ehlukile. Ngokusebenzisa i-AERMOD, isofthiwe ethandwa yi-EPA, ukukhishwa kwegesi kwehla ngo-60% ku-300 m kanye no-90% ku-600 m— kodwa kuphela ngaphansi kwezimo zomkhathi ezingathathi hlangothi . Ekuseni okuzolile nomswakama, leyo nkungu ingagubha umhlabathi isikhathi eside. Iphuzu elibalulekile: uma ungakhetha, khetha uhlangothi oluya phezulu lomgwaqo bese uhlose ukubuyela emuva okungenani amamitha angu-600.
Ukubanjwa Okufihliwe: Umsindo, Ukudlidliza kanye Nenani Lempahla
Ikhwalithi yomoya iyaba yinto evelele, kodwa abanikazi bezindlu bakhononda kabuhlungu cishe ngo-5 ekuseni ngama-beeper okusekela kanye nokuduma kweloli okuzinzile. Ukuhlolwa kuka-2020 eCharlotte, eNC, kubonise amanani ehla ngo-5-7% ngaphakathi kwamamitha angu-400 ukusuka endaweni ye-asphalt—ngisho noma iphunga lalilincane. Kubonakala sengathi abathengi bafaka ingozi ebonwayo ezipeshelini kakhulu kunemibiko ye-EPA.
Amafulegi Abomvu: Lapho "Kuphephile" Kuphenduka Kungacacile
Qaphela lezi zimpawu eziyisixwayiso:
- Ukungacaci kwe-stack >20% isikhathi esingaphezu kwemizuzu emi-3/ihora (kubonakala njengomusi omnyama).
- Izikhalazo ezivame ukubhalwa ku-hotline ye -odor hotline yenhlangano.
- Izimvume eziphelelwe yisikhathi—hlola isizindalwazi se-inthanethi sesifundazwe sakho.
Uma kukhona ababili, funa umhlangano womphakathi; abalawuli bavame ukufika uma amakhamera efika.
Uhlu Lokuhlola Olusebenzayo: Ukuvikela Umndeni Wakho Ngaphandle Kokuthutha
Awukakulungeli ukuthengisa? Kulungile. Yibhekane nochwepheshe:
- Faka izihlungi ze-MERV-13 HVAC; shintsha njalo ezinsukwini ezingama-90.
- Tshala izihlahla ezihlala ziluhlaza eziminyene ohlangothini olubheke endaweni; zisika izinhlayiya ezingu-15-20%.
- Sebenzisa inzwa ye-Purple-Air engu-$200 bese ushicilela idatha—opharetha bengcindezi yokucaca.
- Hlela ukujima ngaphandle ngemva kuka-10 ekuseni; izitshalo eziningi zilayisha kusenesikhathi.
Futhi, ungakhohlwa ukuvota ezinkundleni zokuxhumana zendawo — ukungenelela kwezempilo okushibhile kakhulu “kuwuku-yebo” ekubuyiseleni emuva ngamamitha ayi-1,000.
Ubuchwepheshe Besikhathi Esizayo: I-Asphalt Ehlanganisiwe Ngokufudumele kanye Nomusi Oncishisiwe
Imboni ayimi ndawonye. Izithasiselo ezixutshwe ngokufudumala zinciphisa amazinga okushisa okukhiqiza ngo-30–50 °C, zinciphisa ama-VOC afinyelela ku-50%. Izitshalo ezisebenzisa izinhlelo zokubamba umusi oluhlaza okwesibhakabhaka zibika ukukhishwa kwe-benzene ngaphansi kwemingcele yokutholakala. Ukuhumusha kwabahlali: izakhiwo ezintsha zihlanzekile, ngakho-ke ukulungiswa kabusha kubaluleke kakhulu kunobudala bekhalenda.
Isixazululo Sezomthetho: Lokho Ongakufuna
Ngaphansi koMthetho Womoya Ohlanzekile, izakhamuzi zingacela ukubuyekezwa kwemvume yeSihloko V. Isicelo esaphumelela ngo-2019 saphoqa isikhungo saseLouisiana ukuthi sifake izihlungi zekhabhoni, kwehlisa ama-HAP (ukungcola komoya okuyingozi) ngo-70%. Izindleko? Iqembu lomphakathi, ummeli, kanye nezinyanga ezingu-18 —okuncane kakhulu kunecala lesenzo seqembu .
Ngakho-ke, Ingabe Kuphephile Ukuhlala Eduze Nesitshalo Se-Asphalt?
Ngokwezibalo, kubantu abadala abaphilile ngaphandle kwendawo engamamitha angu-300, ingozi iphansi futhi iyafana nokuhlala eduze komgwaqo omkhulu. Amaqembu azwelayo—izingane ezine-asthma, asebekhulile—kufanele aphikelele okungenani kumamitha angu-600 kanye nezilawuli zesimanje. Qaphela ukuthuthukiswa kwezimvume, sebenzisa ubuchwepheshe obungabizi ukuqapha umoya wakho wangaphakathi, futhi ucindezele iziphathimandla zendawo ukuthola idatha ecacile. Yenza lokho, futhi uzoshintsha umbhalo kusukela kohlalayo okhathazekile uye kothintekayo onolwazi.
