Wasakhowga hawada dibadda iyo walxaha qayb ka ah (PM) ayaa loo kala saaray inay yihiin kooxda 1-aad ee kansarka sanbabada. Ururada wasakhaysan ee qaba kansarka dhiigbaxa ayaa soo jeedinaya, laakiin kansarradani waa kuwo aetiology ahaan ka duwan oo baadhitaano-hoosaadyada ayaa ka maqan.
Hababka
Daraasada Kahortagga Kansarka Bulshada Kansarka Mareykanka-Kooxda Nafaqada II ayaa loo isticmaalay in lagu baaro ururada wasakhowga hawada dibadda ee qaba kansarrada dhiigbaxa dadka waaweyn. Tirakoob-kooxeed-kooxeed saadaasha sanadlaha ah ee walxaha yaryar (PM2.5, PM10, PM10-2.5), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), iyo carbon monoxide (CO) ayaa lagu meeleeyay cinwaano la deggan yahay. Saamiyada khatarta ah (HR) iyo 95% ee isku-kalsoonida (CI) ee u dhexeeya wakhtiga kala duwan ee wasakhowga iyo noocyada hoose ee dhiigbaxa ayaa la qiyaasay.
Natiijooyinka
108,002 ka mid ah ka qaybgalayaasha, 2659 kansar oo dhiigbax ah ayaa la aqoonsaday laga soo bilaabo 1992-2017. Heerarka sare ee PM10-2.5 ayaa lala xiriiriyay lymphoma unugga mantle (HR per 4.1 μg/m3 = 1.43, 95% CI 1.08-1.90). NO2 waxay la xiriirtay Hodgkin lymfoma (HR per 7.2 ppb = 1.39; 95% CI 1.01-1.92) iyo lymphoma zone marginal (HR per 7.2 ppb = 1.30; 95% CI 1.01-1.67). CO waxay la xiriirtaa aagga margin (HR per 0.21 ppm = 1.30; 95% CI 1.04-1.62) iyo T-cell (HR per 0.21 ppm = 1.27; 95% CI 1.00-1.61) lymphomas.
Gabagabadii
Doorka wasakhowga hawada ee kansarka dhiiga waxaa laga yaabaa in hore loo dhayalsaday sababtoo ah nooc-hoosaadka kala duwanaanshiyaha.
Waxaan u baahanahay hawo nadiif ah si aan u neefsano, iyo codsiyada badankoodu waxay u baahan yihiin sifooyin hawo oo habboon si ay si sax ah u shaqeeyaan, markaa waa muhiim inaan ka warqabno agagaarkeena. Arrin tan la xiriirta, waxaan bixinaa dareemeyaal deegaan oo kala duwan si loo ogaado walxaha sida ozone, carbon dioxide iyo xeryahooda organic kacsan (VOCs).
