Sei Vanhu Vari Kutaura NezveNjodzi Dzehutano Hwezvirimwa zveAsphalt Zvakare?

Driva uchipfuura chero purojekiti huru yemugwagwa uye uchaona masilo marefu, mabhandi ekufambisa zvinhu uye mapfupa emhepo: chimiro chisingakanganisike chefekitori yeasphalt. Kune varidzi vemakondirakiti aya zvinoreva mabasa nekufambira mberi, asi kune vagari vanobvunza mubvunzo wekukurumidzira - njodzi dzehutano hwefekitori yeasphalt dziri kupinda chinyararire munzvimbo dziri pedyo here? Mumakore mashanu apfuura, Google Trends inoratidza kuwedzera kwe60% mukutsvaga "hutano hwehutsi hwefekitori yeasphalt," chiratidzo chekuti nharaunda, mainshuwarenzi uye kunyange vanoisa mari vemakanzuru vanoda kujekeswa.

Chii Chinobva MuAsphalt Plant Stack?

Nzvimbo dzekugadzira asphalt (HMA) dzinoshandiswa pakuomesa zvinhu pa300 °C uye kuzviputira nebhitumini. Kusanganiswa kwezvinhu zvinopisa zvakanyanya, zvinosunga petroleum uye zvinogadziriswazve asphalt pavement (RAP) zvinoburitsa musanganiswa wezvinosvibisa:

• Zvinhu zvidiki (PM10 & PM2.5) — zvidimbu zvidiki zveguruva nemahydrocarbon akasanganiswa zvinopinda mukati memapapu.
• Polycyclic aromatic hydrocarbons (PAHs) —rudzi rwemakemikari anopfuura zana, akawanda acho akarongwa neIARC seanokonzera kenza muboka 1 kana 2A.
• Zvidimbu zvinonyungudika muBenzene —zvinowanzo shandiswa senzira yekudzivirira zvinhu zvine chepfu zviri muutsi hwebhitumini.
• Carbon monoxide, sulfur dioxide uye nitrogen oxides — magasi ane chekuita nekunetseka kwekufema uye kuumbwa kweutsi.

Tichichinja kubva pamakemikari kuenda kuepidemiology, mubvunzo wekutevera uri pachena: zvinhu izvi zvinosvika papi chaizvo?

Kuswedera Pedyo Kwakanyanya Sei? Uchapupu hweEpidemiologic pamusoro peNjodzi dzeUtano hweMiti yeAsphalt

Ongororo yakakosha yegore ra2020 muEnvironmental Research yakabatanidza zvidzidzo gumi nemasere zvebasa uye zvemunharaunda. Vashandi vane makore ≥ gumi ekurapwa neHMA vakaratidza kuwedzera kwe34% kwengozi yekenza yemapapu mushure mekusvuta fodya. Kunyange zvazvo vagari vemo vasingawani dose yakafanana, kuva pedyo kunokosha. 2022 Health Impact Assessment (HIA) muNorth Carolina yakaratidza kupararira kwePM2.5 kubva pamuti we300 K-ton pagore uye yakafanotaura:

• Nzvimbo ye 0–500 m: imwe 1.3 µg/m³ avhareji yePM2.5 pagore; kuwedzera kwakakosha kwekushanyira vana vane asthma nekuda kweER.
• Nzvimbo ye500–1 500 m: inowedzera 0.4 µg/m³; mutoro wehutano unoyerwa asi wakaderera.
• Kupfuura 2 000 m: njodzi yakaratidzwa isingasiyaniswi kubva kumashure.

Kushandura? Kana chikoro chemwana wako kana imba yekurerera iri mukati memamita makumi matatu, kubvumirana kwesainzi kunoti njodzi imwe inogona kunge iripo - chokwadi chisingawanzo ziviswa nemasangano ekuchengetedza nzvimbo.

Guta reRiverside, Oregon (raive nevanhu 4 200) rakatarisana nehurongwa hwekuvaka chivakwa cheHMA chine 450 K-ton muna 2019. Vagari vemo vakaumba sangano risingabatsiri reClear Air Riverside uye vakabhadhara $12 000 yemasensa ePAH anotakurika. Mumazuva makumi mapfumbamwe, huwandu hwePAH hwemasikati huri 400 m kubva panzvimbo yefekitori hwakawedzera kubva pa7 ng/m³ (pamberi pekuvakwa) kusvika pa27 ng/m³, zvichikwira kusvika pa110 ng/m³ panguva yekukwira kwemigwagwa masikati. Vaine ruzivo urwu, bhodhi redunhu rakaramba mvumo yemhepo, vachiti "njodzi yekenza yehupenyu hwese iri pamusoro pe1 pa10 000."

Varidzi vedzimba, vashandi nevanoronga maguta vanofanira kuitei?

Kana Uchigara Pedyo:

• Kumbira mvumo yeChinyorwa V chechirimwa — inoronga zvese zvinosvibisa zvinodzorwa; enzanisa nezvinodiwa zvemhepo yemuchadenga.
• Pinda kumisangano yeruzhinji uye kumbira kuti pave nevanoona nezvekuchengetedzwa kwezvakatipoteredza (PM2.5 monitors) nguva dzose; ruzivo runofanira kuiswa pawebhusaiti yeDEQ mukati memazuva makumi matatu zvichienderana nekuvandudzwa kwemutemo weEPA wegore ra2023.
• Funga nezve sensor yemhando yenharaunda (PurpleAir, AirBeam) kuti unyore humbowo; matare anogamuchira ruzivo rwakasimbiswa.

Kana Uchishanda Pafekitori:

• Simbisai kushandisa ma respirators ehafu-mask ane ma cartridge eOV-P100 panguva yekuchenesa silo; OSHA's 29 CFR 1910.1001 inoisa 5 mg/m³ TWA yeutsi hwebitumen, asi NIOSH inokurudzira < 1 mg/m³.
• Sundidzirai kuchinjana kwemabasa; njodzi yekenza yemapapu inokwira zvichienderana nemakore anowanzoonekwa.

Kana Uchigara Pabhodhi Rekuronga:

• Tora buffer ye 1 000 m yezvivakwa zveHMA zviri pedyo nezvikoro, zvipatara nenzvimbo dzinochengeterwa vakwegura; izvi zvinoenderana nemirairo iri muGermany neNetherlands.
• Ita ongororo dzeguruva rinobuda kamwe chete pagore, kwete gore rega rega; zvinoda kuti zvinhu zvivharwe uye mabhedha emota akafukidzwa.

Kuchinjira kunyaya dzemutemo, yeuka kuti mainishuwarenzi emhosva ava kutengesa mitengo yekusvibiswa kwevagadziri veasphalt ne25-30% kupfuura makore gumi apfuura—chikurudziro chekuvandudza nekuzvidira.
