Wasakhowga hawada ee bannaanka iyo walxaha qashinka ah (PM) waxaa loo kala saaraa inay yihiin kansar-sideyaasha kooxda 1aad ee aadanaha ee kansarka sambabada. Xiriirka wasakhaysan ee la leh kansarka dhiigga waa wax soo jeedin ah, laakiin kansarradani waa kuwo aan la xiriirin aetioloji ahaan iyo baaritaanno nooc-hoosaad ah ayaa maqan.
Hababka
Kooxda Nafaqada ee Ka Hortagga Kansarka ee Ururka Kansarka Mareykanka-II ayaa loo isticmaalay in lagu baaro xiriirka wasakhowga hawada bannaanka ee qaba kansarka dhiig-mareenka ee dadka waaweyn. Saadaasha sanadlaha ah ee heerka kooxeed ee walxaha qashinka ah (PM2.5, PM10, PM10-2.5), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), iyo kaarboon monoksaydh (CO) ayaa loo qoondeeyay cinwaanada guryaha. Saamiyada khatarta (HR) iyo 95% isku-kalsoonaanta kalsoonida (CI) ee u dhexeeya wasakhowga waqtiga kala duwan iyo noocyada hoose ee dhiig-baxa ayaa la qiyaasay.
Natiijooyinka
108,002 ka qaybgalayaasha ka mid ah, 2659 kansar oo ku dhacay dhiigga ayaa la aqoonsaday laga bilaabo 1992-2017. Fiirsashada sare ee PM10-2.5 waxay la xiriirtay lymphoma-ka unugyada mantle cell (HR halkii 4.1 μg/m3 = 1.43, 95% CI 1.08–1.90). NO2 waxaa lala xiriiriyay lymphoma-ka Hodgkin (HR halkii 7.2 ppb = 1.39; 95% CI 1.01–1.92) iyo lymphoma-ka aagga marginal (HR halkii 7.2 ppb = 1.30; 95% CI 1.01–1.67). CO waxaa lala xiriiriyay aagga marginal (HR halkii 0.21 ppm = 1.30; 95% CI 1.04–1.62) iyo T-cell (HR halkii 0.21 ppm = 1.27; 95% CI 1.00–1.61) lymphomas.
Gunaanad
Doorka wasakhowga hawada ee kansarka dhiigga ayaa laga yaabaa in hore loo dhayalsaday sababtoo ah kala duwanaanshaha nooca hoose.
Waxaan u baahanahay hawo nadiif ah si aan u neefsano, inta badan codsiyada waxay u baahan yihiin astaamo hawo oo habboon si ay si sax ah u shaqeeyaan, sidaa darteed waa muhiim inaad ka warqabto agagaarkeenna. Arrintan awgeed, waxaan bixinnaa dareemayaal deegaan oo kala duwan si loo ogaado walxaha sida ozone, kaarboon laba ogsaydh iyo isku-dhafka dabiiciga ah ee isbeddela (VOCs).
