Masensa a Zachilengedwe Amayang'ana Ubwino wa Mpweya

Kuipitsidwa kwa mpweya wakunja ndi tinthu tating'onoting'ono (PM) zimagawidwa m'gulu la Gulu 1 la anthu omwe amayambitsa khansa ya m'mapapo. Kugwirizana kwa zinthu zodetsa ndi khansa ya m'magazi kukuwonetsa, koma khansa izi ndizosiyana kwambiri ndipo palibe mayeso amitundu ina.

Njira
Kafukufuku wa Cancer Prevention Study-II Nutrition Cohort wa ku America Cancer Society unagwiritsidwa ntchito pofufuza mgwirizano wa mpweya woipa wakunja ndi khansa ya m'magazi ya akuluakulu. Kuneneratu kwa pachaka kwa magulu a anthu pamlingo wa Census block kwa tinthu tating'onoting'ono (PM2.5, PM10, PM10-2.5), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), ndi carbon monoxide (CO2) kunaperekedwa ndi ma adilesi okhala. Ma hazard ratios (HR) ndi 95% confidence intervals (CI) pakati pa zoipitsa zosiyanasiyana nthawi ndi mitundu ya m'magazi zinayerekezeredwa.

Zotsatira
Pakati pa anthu 108,002 omwe adatenga nawo mbali, anthu 2659 omwe adapezeka ndi khansa ya m'magazi adapezeka kuyambira 1992–2017. Kuchuluka kwa PM10-2.5 kudalumikizidwa ndi mantle cell lymphoma (HR pa 4.1 μg/m3 = 1.43, 95% CI 1.08–1.90). NO2 idalumikizidwa ndi Hodgkin lymphoma (HR pa 7.2 ppb = 1.39; 95% CI 1.01–1.92) ndi marginal zone lymphoma (HR pa 7.2 ppb = 1.30; 95% CI 1.01–1.67). CO idalumikizidwa ndi marginal zone (HR pa 0.21 ppm = 1.30; 95% CI 1.04–1.62) ndi T-cell (HR pa 0.21 ppm = 1.27; 95% CI 1.00–1.61) lymphomas.

Mapeto
Udindo wa mpweya woipitsa pa khansa ya m'magazi mwina sunaganiziridwepo kale chifukwa cha kusiyana kwa mitundu ina.

Timafunikira mpweya woyera kuti tipume, ndipo ntchito zambiri zimafuna mpweya woyenera kuti ugwire bwino ntchito, choncho ndikofunikira kudziwa bwino malo otizungulira. Pachifukwa ichi, timapereka zida zosiyanasiyana zoyezera zachilengedwe kuti tizindikire zinthu monga ozone, carbon dioxide ndi volatile organic compounds (VOCs).
