Ngaba Kukhuselekile Ukuhlala Kufutshane Nesityalo Se-Asphalt? Nantsi Oko Idatha Ikutshoyo Ngokwenene
Kutheni Abathengi Nabaqeshi Bezindlu Ngequbuliso KuGoogle “Ngaba Kukhuselekile Ukuhlala Kufutshane Nesityalo Se-Asphalt?”
Ukuba wakha wadlula kwi-silo enkulu yesilivere ekhupha amafu amhlophe, mhlawumbi ukhe wazibuza, " Ngaba kukhuselekile ukuhlala kufutshane nesityalo se-asphalt? " - ewe, nam . Kwiminyaka emihlanu edlulileyo, iiforam zepropathi kunye namaqela e-Facebook anomdla kakhulu kule nkxalabo. Ingxaki iyinyani: ukuveliswa kwe-asphalt kubandakanya ukomiswa kwe-aggregate ngobushushu obuphezulu, ukuxuba ne-bitumen, kunye nokugcinwa kwi-300 ° F. Ivumba lodwa libangela i-alamu, kodwa zityhila ntoni izifundo eziphononongwe ngontanga?
Ukubeka esweni umgangatho womoya: Amanani ezona zihloko zibalaseleyo azitsitywayo
Masiyiyeke loo nto yokoyika size sijonge idatha yehlabathi lokwenyani . Ngowama-2022, iKhomishini yaseTexas yoMgangatho weNdalo yabeka iimonitha eziphathwayo kwi-150 m ukusuka kwiziko lokuxuba iidrama. Ngaphezulu kweenyanga ezili-18:
- I-PM₂.₅ ingumndilili we-9.4 μg/m³—ngaphantsi kwesikhokelo se-WHO se-15 μg/m³.
- Uvavanyo lweBenzene lufikelele kwi-0.8 ppb, phantse ngendlela efanayo nendawo exakeke kakhulu esixekweni.
- Ii-polycyclic aromatic hydrocarbons (ii-PAH) zifunyenwe, kodwa kwi-1/20th inqanaba lifunyenwe kufutshane nezikhululo zamandla ezisebenzisa amalahle.
Uguqulelo? Kwiintsuku ezininzi, ubuninzi bongcoliseko bebungahlukani namanqanaba asezidolophini. Nangona kunjalo, "iziganeko zokulayisha" zexesha elifutshane (xa iilori zilahla i-aggregate) zinyusa i-PM₂.₅ ukuya kwi-35 μg/m³ imizuzu engama-30–45. Kulapho ibali liqala khona ukucaca.
Oko Kuthethwa Zizazinzulu Xa Zisithi “Umngcipheko Owamkelekileyo” Xa Zithelekiswa Nabantu Abahlala Kwivumba Lazo
Nantsi eyona nto ibalulekileyo: ivumba aliyotyhefu. Impumlo yomntu inokufunxa ii-thiols ezityebileyo kwi-sulfur kwi-parts-per-billion, kodwa umgangatho wempilo yabo usondele kwi-parts-per-million. Uphononongo lweYunivesithi yaseCincinnati ka-2021 lufumanise ukuba abemi abakumgama we-1 km baxela iintloko ezibuhlungu kunye nokucaphuka komphimbo ngokuphindwe kabini ngexesha lokutshintsha kwehlobo, kodwa uvavanyo lomsebenzi wamaphaphu luhlala luqhelekile. Ngamanye amazwi, ukucaphuka ≠ isifo .
Ngaba Ugcina Iifestile Zakho Zivaliwe? Ngaba Ufumana Isiphumo Esichasene Nokungaqondakali?
Abaphandi bafake iisampuli zomoya zangaphakathi kwizindlu ezingama-42. Okumangalisayo kukuba, izindlu ezine-mechanical ventilation (HRV/ERV) zibonise amanqanaba aphantsi e-PAH kunezo zingeniswe umoya ngokwendalo, nokuba iifestile zivaliwe. Isifundo: ukuvala ikhaya lakho sisiqingatha semfazwe; ukuhamba komoya okucociweyo kuyayigqiba.
Ukubola komgama: Kukufutshane kangakanani?
Izikhokelo zoshishino zakha zasebenzisa i-mantra ethi “500 ft kwaye uphilile.” Iimodeli zanamhlanje zokusasazeka zixela ibali elahlukileyo. Ukusebenzisa i-AERMOD, isoftware ethandwayo yi-EPA, ukukhutshwa komoya kwehla ngama-60% kwi-300 m kunye nama-90% kwi-600 m— kodwa kuphela phantsi kweemeko zomoya ezingathathi cala . Ngeentsasa ezizolileyo nezinomswakama, loo mphunga unokugubungela umhlaba ixesha elide. Ingongoma ephambili: ukuba ungakhetha, khetha icala elinomoya ovuthuzayo esitalatweni kwaye ujonge ukubuyela umva ubuncinane ngama-600 m.
Ukubanjwa Okufihlakeleyo: Ingxolo, Ukungcangcazela kunye nexabiso lePropati
Umgangatho womoya uyaba yinto ebonakala kakhulu, kodwa abanini bezindlu bakhalaza kabuhlungu malunga nentsimbi yesi-5 kusasa ngee-beeper zokuxhasa kunye nokuduma kwelori okuzinzileyo. Uvavanyo lwango-2020 eCharlotte, eNC, lubonise ukuba amaxabiso ehla nge-5–7% ngaphakathi kwe-400 m ukusuka kwindawo ye-asphalt—nangona ivumba lalincinci. Kubonakala ngathi abathengi bajonga umngcipheko obonwayo kwizibonelelo ngaphezu kweengxelo ze-EPA.
Iiflegi Ezibomvu: Xa "Ukhuseleko" Lujika Lube Lubi
Lumka kwezi mpawu zilumkiso:
- Ukungacaci kwe-stack >20% ngaphezulu kwemizuzu emi-3/iyure (kubonakala njengomsi omnyama).
- Izikhalazo ezihlala zifakwa kumnxeba we-odor hotline we-arhente.
- Iimvume eziphelelwe lixesha—jonga isiseko sedatha se-intanethi selizwe lakho.
Ukuba kukho ababini abakhoyo, funa intlanganiso yoluntu; abalawuli badla ngokubonakala xa kukho iikhamera.
Uluhlu Lokujonga Olusebenzayo: Ukukhusela Usapho Lwakho Ngaphandle Kokufuduka
Awukulungelanga ukuthengisa? Kulungile. Yilungise njengengcali:
- Faka izihluzi ze-MERV-13 HVAC; zitshintshe rhoqo emva kweentsuku ezingama-90.
- Tyala izityalo ezihlala ziluhlaza ezixineneyo kwicala elijonge kwindawo; zisika iinxalenye zezityalo nge-15–20%.
- Sebenzisa i-sensor ye-Purple-Air eyi-$200 kwaye upapashe idatha—abaqhubi bexinzelelo lokucaca.
- Cwangcisa ukuzilolonga ngaphandle emva kwentsimbi ye-10 kusasa; uninzi lwezityalo luzalisa kwangethuba.
Kwaye, ungalibali ukuvota kwiindibano zasekuhlaleni zokwahlulwa kweendawo —ungenelelo lwezempilo olungabizi kakhulu “kukuba ulinde” ukuba ubuyele umva ngeenyawo ezili-1,000.
Itekhnoloji yexesha elizayo: I-Asphalt exutywe ngobushushu kunye ne-Fumes encitshisiweyo
Eli shishini alimi ndawonye. Izongezo zomxube ofudumeleyo zinciphisa amaqondo obushushu emveliso ngama-30–50 °C, zinciphisa ii-VOC ukuya kuthi ga kwi-50%. Izityalo ezisebenzisa iinkqubo zokubamba umsi oluhlaza okwesibhakabhaka zibika ukukhutshwa kwe-benzene ngaphantsi kwemida yokubhaqwa. Inguqulelo kubemi: izakhiwo ezintsha zicocekile, ngoko ke ukuhlaziywa kwazo kubaluleke ngaphezu kobudala bekhalenda.
Inkxaso-mali Yezomthetho: Oko Unokukufuna
Phantsi koMthetho woMoya ococekileyo, abemi bangafaka isicelo sokuhlolwa kwemvume yeSihloko V. Isicelo esaphumelela ngo-2019 sanyanzela indawo yaseLouisiana ukuba ifake izihluzi zekhabhoni, nto leyo eyabangela ukuba i-HAPs (ukungcola komoya okuyingozi) ilahle i-70%. Ixabiso? Iqela loluntu, igqwetha, kunye neenyanga ezili-18 —ingxaki encinci kakhulu kunetyala lesenzo samaqela .
Ngoko ke, Ngaba Kukhuselekile Ukuhlala Kufutshane Nesityalo Se-Asphalt?
Ngokwezibalo, kubantu abadala abasempilweni ngaphandle kommandla weemitha ezingama-300, umngcipheko uphantsi kwaye uyafana nokuhlala kufutshane nomgaqo omkhulu. Amaqela anovakalelo—abantwana abane-asthma, abantu abadala—kufuneka bagxininise ubuncinci kwiimitha ezingama-600 kunye nolawulo lwanamhlanje. Hlala ujonge ukuphuculwa kweemvume, sebenzisa ubuchwepheshe obufikelelekayo ukujonga umoya wakho wangaphakathi, kwaye ukhuthaze oorhulumente basekuhlaleni ukuba bafumane idatha ecacileyo. Yenza loo nto, kwaye uya kutshintsha umbhalo ukusuka kubemi abaxhalabileyo ukuya kubathathi-nxaxheba abanolwazi.
